3rd Party Chargers (also, beware of faulty ASUS chargers)

I'm curious if anyone's found any 3rd party chargers (or cradles) yet. Mine overheated and had a meltdown and I'm having some difficulty getting Asus to replace the darn thing.
Pics below. Beware. The watch seems fine, but was hot as hell when I took it off the charger in the morning.

Jed123, I had the same thing happen to my charger this morning. Did you have success getting ASUS to replace it? THanks.

I tried for 2 weeks to get them to help me and both tech & customer service were pretty inept. By the time I'd gotten to the point where they were willing to replace the cradle, I decided to just return the thing to Best Buy.
Were I to do this entire thing all over again, I'd have just gone to Best Buy for an exchange. They do it immediately, no questions asked. Asus is hopeless.
But to be honest, I was sorta glad to give it back, charging issues aside. The watch just didn't do enough for me. I liked it while I kept my expectations low and tried not to think about it. But when I did, boy I'd get a bit frustrated with how half-baked it was, even as an early adopter product.

Weird, I feel almost exactly the opposite, that there's very little about it that needs improvement. I guess I'm coming from a different place. I was really an early adopter: I used the first Sony Smartwatch for 2-1/2 years before getting the Asus. Compared to the old Sony, these Wear devices are amazingly good.

Same here. Love mine for now. lol

Could be the problem root cause be that the charger shipped with the cradle has an 1.35 A output , while the cradle itself is badged Input 5V, 0.5A ??? little bit too much current!!!

I actually had really good customer service from Asus. I emailed them, got an RMA and sent the watch and charging cradle to them and had it back within a week. They replaced the battery in my watch and gave me a new cradle. I sent the watch too bc I couldn't even power it on. I have pretty happy with it and have had it since Christmas.

I charge watch from PC with USB 2.0 with max current is less than 1A (my guess it is limited to 0.5A) so hopefully it won't overheat. Still enough to fully charge watch in a reasonable time.

No. As long as the voltages match, you should be good. The current needs to be the same or greater than what the watch expects. It will pull what it needs. What would be bad would be an adapter that is greater than 5V. I fried an old Palm PDA that way back in the day when I was getting started. I'd be curious to know if the watch was doing anything intensive when it was charging (something that would keep it on an generate heat and warming the charging paddle up) or if it was placed somewhere that would cause it to heat up?

Hi,
I'm using the usb cable connected to my laptop USB, it takes a long time to charge (sometimes it's seems like it's not charging).
And i also have flickering screen when browsing through the quick settings.
can anyone tell me where i can get a EU charger? i've ordered mine in the US , but i live in europe.
Or maybe i just can use a generic US to EU adapter for the wall charger?
Thanks!

It doesn't work that way. The current rating denotes the max current the watch would ever draw, and the max current capable of being produced by the converter.
The converter can output a maximum of 1350 milliamps, whereas the watch consumes 500 milliamps. There's no way the watch would (under normal circumstances) consume more than 500ma, unless there's a short circuit. I suspect the problem was a thermal issue in the internal lithium-ion battery. If the charge regulator doesn't detect that the battery is fully charged, it won't shut off the input current, and the battery can (eventually) go into thermal breakdown. See Thermal Runaway.

My personal opinion about exploding Note 7 batteries...

First of all, I'm not a noob regarding electronics and batteries.... Second, I don't think Samsung did such a stupid mistake like using millions of batteries without testing them and third, I don't think that a company who is producing batteries for a mammoth like Samsung can afford to sell defective batteries, or not properly tested batteries...
I'm the owner of a blue Note 7, and I am ready to take the chance and NOT exchanging the phone.
And this is why:
(please excuse my English...)
At the beginning, I have noticed that every single time when I was charging my phone, the phone was kinda overheating... Not too much, but still....
After that, the big scandal about exploding batteries was everywhere in the media...
I have read in the phone settings that SPEED CHARGING can overheat your phone (actually is overheating just the battery)....
So I've just disabled the speed charging on the phone and the now the phone is always cool
So my personal opinion:
I think that the problem is somewhere in the speed charging process, something that is shocking and putting too much pressure on the batteries, probably not proper designed for fast charging.
So I'm taking the risk and not exchanging my phone, and I suggest to all of you guys who are not exchanging your devices to do the same, especially because the charging speed is not too much different regarding the speed!!!
Please test and post your experience regarding charging speed and phone temperature with the fast charging option enabled/disabled....
Thanks, and again, this is my personal opinion, and I'm not advising anyone NOT to exchange the phone.

Just a couple of points on your post.
1. It's not all phones that have the reported problem - Samsung have a few different battery suppliers and only one has delivered faulty ones. The problem is that Sam has no record of which phones they went into.
2. Phones sold in China have not been recalled because Sam knows the dud batteries weren't used for that batch.
So a general charging problem doesn't explain the situation. But yes of course fast charging will make the battery hot.

My personal opinion what is the big deal no sweat off your back. Change the phine and get it over with.
The liability you are assuming is not worth a few hours of set up

on the testing front, it is impossible and far too time consuming and detrimental to the product to conduct full scale testing on every single thing coming out of a factory, the fact is mass production should make it so item 1 and item 1 million are identical, so due to the process they will do spot checks randomly testing say 1 in 100, now when you hit a problem like this battery fault where the actual fault is a very very small percentage it's like trying to find a needle in a haystack, you can poke at it randomly as is the industry norm (even with cars) but the majority of the time you are going to come out with hay. the only way this could have been caught if every single battery was put through intensive inspection and usage tests before they shipped, not only would this add a massive amount to the production cost and time it would also lead to the battery already having some pretty harsh wear and tear on it.
so the testing is pretty much manufacturing standard and the same as every other company worldwide, so if Samsung for doing this then you are saying every single company the world over is stupid.
on not exchanging the phone if the option is there it would be stupid not to, as basically if it does fail down the road and you refused the recall then you have no come back as you were told and given the chance to have a device deemed to be safe.
the fast charging claim was made up by phone shops, it's not one Samsung ever put forward. yes fast charging can generate increased heat, but the battery isn't failing because it is hot, it is hot because it fails. the actual failure of the battery is a short circuit caused by a fault making the 2 sides of the battery to bridge leading to the battery to have a runaway reaction, you can actually do this on any battery should you use something to short both sides of the battery together. now here lies the problem, people erroneously claim don't fast charge as it reduces heat, but when the flaw comes from parts of the battery that should never touch coming into contact with each other, slow charge or fast charge if them 2 parts are close enough they can touch they will eventually. so yeah heat is a symptom not a cause, with temperature things can expand and contract but the fact is if the short can be made on a device anything you do is only delaying the inevitable and there is nothing you can do to stop it eventually failing.
but end of the day if you want to risk it and live with 60% battery power that is up to you.

I agree that the vast majority of batteries are probably fine.
The hassle of keeping will be having to deal with airports, gimped 80% battery and possibly IMEI blacklist.
The hassle of exchanging is getting a unit with screen or hardware other problems. As well as (like in my cause) having to exchange out of region, the process of which still isnt clear to me. I am currently playing ping pong with samsung UK and samsung Gulf (i am the ball)

BTW, I didn't update the phone with the last update, I've just turn off automatic updates in settings... I'm curious if I can skip this and will be able to update next time when Samsung will release a update....

You won't be able to give it away when you come to sell if you don't exchange it.

My note 7 to heated up too during that one time during its first w days. It was really really hot...I turned off fast charging and it never happened again.
I also believe it's related to fast charging...which is on by default.
Using generic adapters and cables hasn't made it hot every since i turned off fast charging.
But I'm still having this replaced..sad because I have no problems with this unit..GPS works perfectly and fast. Battery last long. And now the news is reporting that the new note 7 replacements are showing problems is South Korea. Over heating and not charging....sigh

the updates have to be done in order you can't skip one and go onto the next, if you get the next it will include this one so basically using that method you can never update the phone.

I agree with you 100%, through my own testing i came to the same conclusion which included charging from power point/usb and wireless, i believe heavy use, fast charge and a defective battery caused issues, not just battery issue , in my humble opinion i believe incorrect using of fast charging was probably an issue in all legit cases, but Samsung should of put some type of time limit for fast charging, ie 90 minutes, that way would of negated one part of the equation and probably stopped a few bangs, so blame all around really

If it was fast charging that was the problem don't you think samsung would have disabled it with the replacement phones?

Kudos for starting the thread by stating what's said is "your opinion." We're all operating off of second and third hand data yet some here will defend their interpretations as fact. Clearly they're not and can't be.
This explains the battery issue. If fast charging made batteries overheat than you'd see events like this on every forum for every OEM. S7's don't have this issue and they are only three months behind the Note7 in development and share many of the same internals.

I'm glad that i left Samsung family cuz It was pretty damn sure that someday my phone will kill me
Samsung is going the apple way i guess.... Just to sell it... Now apple doesnt look that expensive.... :/

Yes, you are a noob, you don't know anything about batteries.
Current Li-ion batteries can be safely charged with approximately 40 watts of power. Fast charging in Samsung phones utilizes only 15 or so watts.

It's not the fast charging. It's a just a tiny percentage of batteries with a defect.
I fast charge mine all the time and it stays pretty cool. I'll still switch when my replacement arrived, but in the meantime I am not worried.

Note 7 recall & media distributed information

When you look into the Note 7 recall and all of the information we have available, you have news outlets taking a biased point of view on the units. They have put words into both Samsung and the CPSC's mouth saying that the recalls are MANDATORY, that the Note 7 production has been permanently halted, and that the issue is the battery itself. In the meantime, Samsung themselves have announced that they CANNOT replicate the issue themselves, and the changing out of the battery would generally suggest that it was not the battery causing the problem. Plus, due to media coverage the issue has been severely exaggerated. According to the CPSC, only 96 units out of 1.9 million units sold in the US have been reported as overheating. In the two months since the release of the phone that is a 0.005% failure rate. That means the phone has a 99.995% chance of being perfectly fine. In terms of normal production, that would be considered a success by most companies. Samsung also has not announced anywhere on their site that production has been halted permenantly. They've said temporarily while they investigate. The investigation is NOT COMPLETE.
Now, if you take the battery out of the equation as the primary point of failure, there are three other points of possible failure that would be the most common cause to make the battery ignite. Those are software tampering, hardware tampering/error and the USB-C port/accessories.
Software: a partially flashed firmware could easily damage the charge rate systems to cause damage to the battery itself or damage the battery's protection board to the point where it can cause problems.
Hardware Tampering/Error: How many idiots have you seen on youtube sinking their Note7s to the bottom of a lake/river/pier, or drop testing them from heights that they are not rated for. Then count the # of people who replicate what other people do on youtube.. (Ghost pepper challenges anyone?)
USB-C Port/Accessories: USB-C has been under some controversy itself lately. Cheap USB cables have been sold that when used on devices damage not only the USB-C port, but also the power systems due to the cables being improperly wired. As well, the Note7 comes with USB-C accessories, one of which is a USB-A to a USB-C port adapter. This is used to use the unit AS a backup battery, or to attach flash drives to the unit and NOT to charge the unit. Many people have USB-A to USB-A cables. Imagine if someone used one of the faulty USB-C cables to charge the unit, or tried to use that adapter with a USB-A to USB-A cable to charge the unit. With only 96 cases reported of overheating, it's well within the number of people who don't understand technology enough to get the proper cables and/or use the unit up to spec. If the cable is not CERTIFIED by the USB-IF it could very well be a bad cable and have caused the issue.
What I'm saying here is look at the proof, look at the history of the devices you're attaching to the phone, look at human behavior, look at what the media's doing. We have people in this world who actually think TRUMP would make a good president. We have people in this world who snort condoms up their noses. It makes it completely possible that all 96 reported cases are 96 cases of users doing the wrong thing with their phones. It is very likely that out of 1.9 Million units sold in the US (according to CPSC), 96 of the people who bought Note 7s are simply idiots. (Plus there's a video of an idiot supposedly holding a Note 7 while the phone is catching fire. When a LI-Ion Battery overheats you can't hold it. not in your hands without receiving severe burns. Information below attached so you can see it all directly from the sources for the information on the Note 7 instead of from media locations.
Also, don't forget, some of these people with the phones who have overheated REFUSE to return them to Samsung for investigation. There is only one reason to refuse to turn in a destroyed device. If you tampered with it yourself.

Update: Just spoke with a supervisor at Verizon, and they are AWARE that this is a blown out of proportion recall and issue. As of the current moment, they are supporting the phone INDEFINITELY, until Samsung verifies what the problem is and completes the investigation. Then depending on the investigation result, they will decide what to do. I encourage people to call their carriers and talk to supervisors who have more information.

I ansolutely agree with you, around 100 devices in 2 million +, is better than many other quality standards around, and as you pointed out, many people handle devices in very bad ways

Well said. This is why I'm not getting rid of mine. BTW, you accidently put billion instead of million the first time.
---------- Post added at 12:22 AM ---------- Previous post was at 12:19 AM ----------
Maybe the whole thing is a conspiracy by another company like LG or Apple. Paying people to do this to their phones then paying the media to overhype and overexaterate the whole thing. I don't think it's a coincidence this happened to the best phone Samsung has ever made. Let me rephrase that, the best phone ever created.

Think about this, how rediculous would it be if samsung found out it was an uncertified cable causing the entire problem, and that they took a multi-billion dollar loss over the cable. This is why all of this crap should not be happening until the investigation concludes.

Updated first post with: Also, don't forget, some of these people with the phones who have overheated REFUSE to return them to Samsung for investigation. There is only one reason to refuse to turn in a destroyed device. If you tampered with it yourself.
Fixed billion replaced with million

Update with information from Verizon in first post.

NOW we're talking! Finally my kinda people! Where have you been the past couple of days? Now the dust is settling and the initial "shock" has subsided people are starting to think with clarity. Excuse the pun, but 'Think Different'
Keep it going, I LIKE this!! I was getting so lonely here getting called a conspiracy nut and such. Thank you my people!

I agree. My phone is perfect and I would keep it except I would like to receive updates and such. At&t told me it has a one year warranty. That I don't have to turn it in. I'm struggling real hard with this. I love this damn phone and nothing else compared to it. I think it's just another case of reefer madness.

My theory is that the playdoh like battery is just in a foil like cover, so it's easily squished. They have mentioned possible assembly problems with squishing it inside the phone being the cause, but I wonder if perhaps a high G drop on a floor might distort it sufficiently that, after a number of charge/discharge cycles, may develop those crystals which will fuse internally between squashed plates causing the battery run away we have all seen.
I doubt it is external to the battery as surely between battery and main phone assembly there will be short circuit protection (generally the metallic canister style batteries have this built in, but with a sealed phone and soft battery, this protection is probably the very first thing the phone battery cable plugs into).
I only dropped my N4 twice, my N7 never (ok, it hit ground inside a Gear VR when my son was being silly), but I have seen others who are far less careful with phones that may have dropped and distorted the battery putty enough to be more prone to internally fusing.
Although at least 2 photos show the phone in (melted) protector cases which should reduce the shock loading, perhaps these ones had the extra squished assembly with the SDI batteries which already had less internal tolerances than the Chinese one?

Another funny development that was brought up in another thread... The only video of the unit catching fire is a surveillance video from above... where you cannot actually see what device is spewing the smoke. The only reason its believed to be a note 7 is because someone SAID it is.

Thread cleaned.

The problem is obviously not the charger. I've charged it many times from below 10% all the way to 100 on the samsung unit, and it has never caused a problem. My best guess is that it wont fail because I am using a certified cable.

Perhaps samsung should go the apple route and put a chip in their chargers so only certified chargers work.
With the invention of fast charging technology it is pretty risky to use cheapies.

Do it yourself Hardware Repair

I am making this post so it is more broadly seen by people who have a specific hardware issue.
This solution is for issues specifically with the board being fried or more likely broken solder connection. I found this solution while browsing Chinese Custom Rom threads and apparently it works.
Absolutely it's better to pay a professional reball the broken solder connection.
There is a do it yourself/cheap method that definitely does not involve using an Oven.
I included photos at the bottom of the link and rather than create a redundant post, for something that I have already made : Go here for the Jerry Rig Suggestion

Good Luck
Make sure you followed all of the unbricking steps here https://forum.xda-developers.com/le-pro3/how-to/unbrick-leeco-phones-leeco-variants-t3847220 before even considering this method..
There are 3 unbricking methods mentioned
Qfil with Flash 2.0 or 1.9 ( Try both)
QPST ( Instructions in first comment of unbricking thread)
Flashbat.all method ( Instructions on Unbrick OP, and in first couple of comments)

Hi
What do you think, can I repair this problem? :
My phone is dead. It is not able to turn on, it just squezing sometimes, if I push the turn on button. The screen is full black since the shut down. No logo no any fastboot screen, nothing. The led light was pale green before the qfil.

I wouldn't bother trying this possible solution unless you are 100% sure that you have broken solder connections. Just because your phone doesnt turn on doesn't mean its the chips. It much more likely that your issue is just the battery.
Also just so you know when the board is fried the phone will still turn on, and will boot to fastboot but not recovery, qfil works but does nothing and if you boot to fastboot and leave it on the fastboot screen the screen will turn to static. At least this is what happens with the majority of chip death issues. However there was one case that I know of on a friends X722 which could not go to fastboot, and that issue ended up being a fried GPU, which this possible fix may resolve.
If you are only getting a black screen leave the phone plugged in overnight ( preferably with a different cable) , After knowing that the phone was charged for long enough what happened? Did the phone get warm at all? Does the phone vibrate?
If the phone does vibrate, try using the QPST method, it's the 2nd post on the Unbricking thread mentioned above in the OP.
Another possible cause of your issue is static, they only way to test and possibly resolved is to unplug the battery from the board and plug back in again. Should you attempt trying this, only use a heat gun to melt the glue holding the screen on...there is alot and a hair dryer will not work, without damaging your LCD.
If I had your issue, I would order a battery and LCD, and swap the battery, there is a good chance it will work. If not you can move on to more drastic solutions such as the one mentioned in the OP. Worse case scenario, you will be out the cost of the battery which is about $7 and LCD which is about $15

This thing here I believe is very important, so much to put it in special color

I guess it's certain now that I have some harware issue, most probably if GPU is separated from the CPU.

I don't know if it's just me who is unlucky but I have lost yet another USB board. This time the one you sent me burnt up as I connected it to my PC. I don't think it's a cable issue because I was using a high quality USB cable from BASEUS. How could it be that I'm not seeing more complaints like mine?
This time I think it could have been caused by dirt in the port because I'd just returned from my rural area and there I did a lot of work involving dirt. Also, there was a slight shower that got me on my way back and I keep the phone in the pocket with the USB port exposed and looking up. My patience with this phone has just about run out now.

I don't know if it's just me who is unlucky but I have lost yet another USB board. This time the one you sent me burnt up as I connected it to my PC. I don't think it's a cable issue because I was using a high quality USB cable from BASEUS. How could it be that I'm not seeing more complaints like mine?
This time I think it could have been caused by dirt in the port because I'd just returned from my rural area and there I did a lot of work involving dirt. Also, there was a slight shower that got me on my way back and I keep the phone in the pocket with the USB port exposed and looking up. My patience with this phone has just about run out now. This is the worst investment I've ever made on a phone :crying:

Wow, sorry to hear that. I think that those LeEco phones are hit or miss. But it really doesn't seem that they were made to last more that a couple of years. I have fried the usb card myself, when I bought very first leeco, its too easy to fry those cards, and in retrospect the Leeco charge is too powerful. The remaining Leeco that I have left charges much better ( stays cooler) when using my Xiaomi Charger.
I agree that you have had some really bad luck. I would not put any more money into it. you are better off buying a cheap Xiaomi...even a used one. You can find some good deals on Amazon and Swappa. Amazon also has refurbished Samsung phones, and they are highly reliable.
You can get a Galaxy 7 for $139 https://www.amazon.com/Samsung-Gala...s=wireless&ie=UTF8&qid=1573693012&sr=1-4&th=1 and they are really good phones.
Here is a renewed One Plus 6T for $267 https://www.amazon.com/OnePlus-A601...ked+cell+phones+renewed&qid=1573693220&sr=8-4
LG V30 for $177 https://www.amazon.com/LG-Camera-Si...ed+cell+phones+renewed&qid=1573693365&sr=8-21
I bought my daughter an A3 and honestly I can't recommend it enough. For a tight budget I personally feel that this is one of the best deals out there for ony $158 ( $50 less than what I paid 2 months ago) https://www.amazon.com/Xiaomi-A3-64...=sr_1_3?keywords=Xiaomi&qid=1573693435&sr=8-3
It has an Amoled Screen and comes with Android One with zero bloatware. You basically get a custom rom experience with a stock phone. To make matters better Android 10 will be released for the A3 in January. The camera, is light years better than the Le Pro 3 and the processor is honestly fast enough, for most of us. No doubt, its more expensive than just getting another card. But saving yourself from the hassles of these constant issues will make it worthwhile. The only drawback is the screen is 720 instead of 1080. But I swear, if you place in side by side with my Mi8, most people would never guess, that the resolution is a little less. Because it's still an amoled screen.
Best wishes, unfortunately I don't have any more working cards or I would send it to you.

I've learned that quick charge is dangerous. I'm using now an usb meter that doesn't let an output beyond 1.4amps to charge my phone now, it charges pretty quickly in fact and my phone doesn't get hot now (even that I live in a hot area)

Yeah. The current pushed by the stock leeco charger is either too high (doubtful) or the charging system of the pro 3 isn't designed to handle quick charge 3 very well (most likely). I have used my stock leeco charger to charge my brother's Nokia 8 (Q.C. 3) and it gets just a little warm even with a case on. Also, the leeco charger is Quick Charge 3 certified so they must have made it according to Qualcomm standards.
I think it's the quality of the parts on the phone itself that are substandard. Since this USB board was sent to me by @tsongming and he had used it quite a while, I believe it could have been perfectly fine. My suspicion is that something else could be wrong with my phone like the USB flex cable. The kind of burning I saw must have been caused by power from the battery because the USB 2.0 port I was connecting to on my PC can only provide 2.5 amps maximum. This is not enough in my opinion to completely melt the usb-c receptacle on the phone. (It's very badly burnt). I will just have to charge the battery externally until I figure out whether it's worth investing any more money into this phone.

My X722 died because I just plugged in the cable to charge. Although I have to admit that the phone socket was not in optimal conditions because I used a crappy cable, so the last one I was using was charging fine but it had to enter in an specific position in order to quick charge to function. It's probably the charger IC that is damaged, but I haven't had the money to send it to repair.
As far as I know, the motherboards just provide 0.5amp unless you are using an special port that can provide more power.
In my opinion 2.5amp at 5v is not that good either, because it's pushing the limit of most phones at 5v.

I am guessing that buying the original $30 USB board from AliExpress won't buy me much time because they have all been used before. Almost every spare part of this phone is not brand new (except for batteries and screens, I guess).
I think it's time to cut my losses. My pro 3 not only needs a new USB board but also a battery and another high quality USB cable. I might buy all of that for $60 only to have the USB port burn again. It doesn't make any sense to keep pouring money into this phone.

What ? $30 usd ? I've seen it in $2.5 for 2 boards, well, not original of course.
You just need to check that it has the extra IC, because there are ones that doesn't has it... although I don't remember what was for that IC, but you can easy see it that some boards just are missing a chip.
As for the cable, I'm using some EFFE cables (EFFE is the brand) and they are working wonderfully, I bought 3 for $7 usd, they plug in fine and stay in too, they were recommended to me by a friend and I'm very happy with them. They even stop giving charge to my dead phone because they detect somehow that there is a short, well, at least that is what my usb meter tells me, although I don't know how do they manage to do that, I don't really think they have an IC in them.

For the record the board that I sent you came from a brand new, LePro 3 not opened bought in the spring 2018. However, I assume that it was made after Leecos public fall. I would guess that it was assembled with C grade parts, because my remaining, working LePro 3 is one of our first Leecos bought in 2016. It's also interesting to note that our 2 remaining X522s are both functioning just fine.
As you said could be the flex cables or just a shoddy soldering job that eventually shortened out the board.
Have you tested the board to be sure that it's not the port itself that is bad?
Another interesting thing to note is that Qualcomm removed Leeco from it's list of approved quick charge device list.
One last reason on why I feel that the charger itself may be part of the problem is that I have a 12 watt portable charger and the Leecos do not get hot at all when using it.
I threw my Leeco charging bricks in the trash after my daughter plugged in my Mi8 for me while I was cooking dinner. Not knowing that I had a preference, she used the Leeco charger.
Later when I checked the phone to see if it was finished charging, I found it was extremely hot, and this phone is rated for QC 4.0. So rather than taking any chances into the trash it went.

Wow!! Leeco really must have used grade c parts. I haven't mistreated that board even once since you sent it. That means it only lasted three months! It is just unbelievably negligent for leeco to use these parts. They must have been from the reject pile.
I don't need to test the board because the USB-C receptacle on the phone is completely melted. Connecting a charging cable seems to cause it to heat up fast and start smoking. It might have been a short on the connector that caused it to burn up. I think the quality of the protruding part with the pin connectors is just poor and repeated use loosens the pins which eventually touch.
I'm done with leeco for good now. I was thinking about fixing the phone to sell but that now seems like a lost cause. I'll keep it until it's dead and then take a hammer to it. Even selling it for spare parts might be a loss for me so I'm stuck with it.

I am sure that they used low quality parts on those last batches of phone, I heard via a friend who lives in Shenzhen that they hired a 3rd party to assemble the final phones... The ones that came with 32gb drives, no nfc or quick charge etc. It sucks because they had so much potential.
Whatever you end up getting. Please do stay in touch, I have enjoyed our conversations and I wish you the best.

This puppy is not out yet. I figure it's got one last hurrah before I throw in the towel. I've been shopping around for a phone with similar performance for around the same price but from the current generation of phones and I've not come across anything else. At least not in the same price range. Performance is very important to me and I just can't take a downgrade. I guess I'm stuck with it for a while.

Its good that it's still working for now. Unfortunately you probably only have 4 to 6 weeks before it stops working completely. I was thinking about you situation and made the list below of additional options/good deals.
The Snapdragon 665 has similar performance to the Snapdragon 821 and the Note 8, (the version with the SD665) can be had for under $200 : https://www.amazon.com/Xiaomi-Displ...keywords=Snapdragon+665&qid=1573874157&sr=8-2
If you can spend a just a little more the Mi8's price has dropped to $250, https://www.amazon.com/Xiaomi-6-64G...ef=sr_1_1?keywords=Mi+8&qid=1573874317&sr=8-1 and I can't recommend it enough. It's definitely my most favorite phone that I have owned and I know that you care about the camera a lot. I can promise that the Mi 8 has one hell of a great camera, and stock camera, is absolutely fantastic, especially with video. In fact, I prefer it for video over the latest Pixel 7.XXX Camera and yes it does Astrophotography.
As I mentioned before the A3, is much better than you would ever expect and you can find them for $150.
If budget is a primary concern: It is definitely worth looking at among the best new phones for the money. Plus the bootloader is easily unlocked with no waiting period. if you want a new phone for around $150. I honestly can't think of a better phone, and as I mentioned my daughter has this phone, so I have actually used it, and I am telling you, it's damn good.
Another option is buying a used 128GB Pixel refurbished $120
I have seen them for as low as $75, or you could buy a One Plus 3T
Edit: I just now found this phone and although it has a mediatek processor, its brand new , has Android 9.0 , 4gb ram, 64 gb hd space and it's just a little over $100 UMIDIGI Power This may be the one, if you can deal with processor but there's a lot of people who say that this phone is great, I dont know if you can use roms, but I have heard that it doesn't have bloatware, so it be a smart buy. Edit : The $118 price is a lightning deal, and the price will go backup to $139 by the time you read this. In that case, I would personally avoid it, but I am am a little biased against mediatek for reasons. Mostly heat and poor battery life.

Tony, you're among very few people I know who are invaluable to communities like these. I'm always impressed by how easily you go out of your way to help community members at XDA. Thank you so much for always being helpful even when you don't have to be. If I had the means I would buy you several cases of beer (or whatever non-alcoholic beverage you like) just to say how much I appreciate you. But for now I can just say THANK YOU!! From the bottom of my heart.
Out of all the options you gave me just now and a few days ago, the brand new Mi A3 is the best option by far. Refurbished is a no-go and yes, I hate Mediatek too. Been there, done that, but once you've got a taste of Qualcomm, there's simply no going back. I'm inclined to go for the A3 because of its AMOLED screen, UFS 2.1, decent camera, and, most importantly, it's price-performance ratio. It doesn't beat the A2 in performance but it more than makes up for it in the additional features.
I am going to keep the pro 3 as long as I can to see if prices drop even more (I'm all about the value). It's only my charging port that's gone so I'm taking out the battery and charging it externally for as long as I can. Everything else works normally. I'm also on my last ROM for this phone -- I can't flash another one because I changed to TWRP 3.2.1 which doesn't see my internal storage anymore (encryption).

Sorry I hadn't seen this post. The cheaper boards tagged as "copy" boards don't have working quick charge or ability to connect to pc for mtp file transfer. They're only good for slow charging and sometimes even that is hit or miss. The boards that cost between $25 and $30 are original leeco boards. Probably not brand new but original. They have all features of the original like quick charge, mtp, otg, cdla and everything else the new phone could do. I wouldn't even consider going close to the cheaper "copy" boards.
I had a single 50 cm baseus USB cable that i bought for around $4 and it was of very good quality. It even supported usb PD and it was built like a tank. Just holding it gives you confidence that it's gonna last a while. Even the board getting fried didn't damage the cable but I'm not using it again. The power pin on the usb cable changed from gold to just plain silver so it must have taken some damage. I would buy a new one to be safe.
I'm done repairing this phone for good. It's not worth the expense and there's too much uncertainty involved even after it's fixed. I could fix it and have it die barely a month later. That would be $50 down the drain. I'm not going through that again.

It seems this phone is on its last leg now. Since yesterday the proximity sensor doesn't work. I think it must be all this opening and closing up of the metal shield to remove the battery. Also, the earpiece speaker only works in loudspeaker mode now. It doesn't work in calls. I think I might have an audio related software issue because sound isn't playing even if I play a music or video file. I have flashed another ROM but this behavior remains. Could this require me to flash persist?
Edit: The earpiece and proximity sensor are acting up because of the damaged USB board. Both work well when I use an app that tests hardware features. They are failing to work for phone calls and video playback because the phone is detecting that I have earphones plugged in. I figured this out when I reflashed a new PIE ROM and saw the headphone icon is always displayed on the status bar even without anything connected to the port. I guess the board getting fried messed up with jack detection.

@tsongming Please tell me if this motherboard is le pro3 x722 or le pro3 x720.

Looking for large Battery/Battery-Case for OP7P

I am looking to swap from an LG V20 (H910) to the OnePlus 7 Pro... The main thing holding me back is a good extended battery for the new phone... With the LG V20, it apparently was one of the last phones that offered a removable battery, and this let it exchange the original 3,200 mAh for a 10,800 mAh battery, and just put on a replacement rear cover... While I know that this will not work on the OnePlus, they do have similar cases available for the iPhones that plug into the normal port and charge them through that port from an extended battery life battery-case...
My searches have so far come up negative, and this is the main issue preventing me getting the phone... I have very large hands, so I actually prefer the phone to be physically large anyway, makes me feel less like I am going to break it...
You help is appreciated

Surely Zerolemon will make one before long, but no word yet. They did one for the last few OnePlus phones, so it would reason the 7 Pro is on the list. Might try a DASH ready power bank, or wait for a WARP ready one to come out but having it built into a case is optimal for some.

I am genuinely interested in the use scenarios for these in modern phones. Do you travel a lot, need multi day use, play a lot of games, use it as a primary work device or actually talk on your phone a lot? I use my phone an embarrassing amount every day, probably more than I should but would not need something like this. Intrigued by demographic of accessories like this.
I have personally used them in the past but when phones were different.

I, too, am hoping zero lemon releases a battery case for the oneplus 7 pro. It's mainly for my prolonged usage of playing pokemon go.

@thetonyclifton I'll give you a good one.
I road ride, quite a bit (for a 50-something guy), I used to race, not that many years ago, so I still ride as far as my darn foot/nerve issue will let me, which can be 75+ (mi), on some weekends.
Here in the PNW, it's very easy to get into areas, even on a road bike where my service (ATT) "wanes" or just is completely gone (this is particularly bad when I go on a long MTB, which is less often).
Same for hiking around here, although I mostly just turn my cell off when I'm hiking, or leave it at home, just depends.
Anyway, if I'm out all day, say 6-8+ hours, on a ride/lunch-stop/ride, along those lines, and going in/out of coverage, it REALLY eats up my battery, FAST. I like to be able to rely on it, to check the weather six times, when it starts to look "threatening" later on, send a few texts, whatever, without wondering if I'm going to run out of juice, towards the end, that kind of stuff. This case would "fit the need", pretty much perfectly", as "one unit", rather than carrying a separate extra battery cable, etc (jersey pockets will only hold so much ;-]).
All that said though, I like using Qi receivers, having come from a LONG line of WinPhones that had the built-in, WAY back, so all my Android phones (Nexus 6, OP5T, OP6, now OP7Pro, the rest "trickled down into our family") have had a Qi receiver on them, behind a basic TPU case.
Occasionally, I carry slim-ish battery pack, with a Qi charging coil built into it, but that's also a bit much for a jersey-pocket.
If I had this type of pack, I'd install it, before long rides/hikes/etc, and and it'd solve my issue, of low-coverage being so darn tough on ANY phone battery, in one, nice, modular package. Not saying I'd buy one of these, 100%, but I'd definitely be a good candidate.
I do hear what you're saying, the "use case" for these having changed a LOT, say from 10 years back, there's no question about the overall advancement making these somewhat less "necessary".
On the other hand, I do like only having to charge my sports-activity watch every 3 days or so, that kind of "appliance-like" dependability is pretty cool; perhaps not necessary in a phone these days, but still pretty cool! I don't think anyone would "turn away" a 2-3 day phone, (say with 4-6hrs screen-on-time/day), if battery-tech evolved, in some rapid way, anytime soon
If this case had an Qi-coil built into it, then I bet it WOULD REALLY SELL, given the lack of Qi coil on the OP7-series, if anyone from ZeroLemon is listening...
So yeah, there's my diatribe, and perhaps some light on an "interesting subject", I suppose...

I do hear what you're saying, the "use case" for these having changed a LOT, say from 10 years back, there's no question about the overall advancement making these somewhat less "necessary".
On the other hand, I do like only having to charge my sports-activity watch every 3 days or so, that kind of "appliance-like" dependability is pretty cool; perhaps not necessary in a phone these days, but still pretty cool! I don't think anyone would "turn away" a 2-3 day phone, (say with 4-6hrs screen-on-time/day), if battery-tech evolved, in some rapid way, anytime soon
If this case had an Qi-coil built into it, then I bet it WOULD REALLY SELL, given the lack of Qi coil on the OP7-series, if anyone from ZeroLemon is listening...
So yeah, there's my diatribe, and perhaps some light on an "interesting subject", I suppose...

Thanks. Yes that is interesting. I can see a use for people regularly away from a charger with very heavy use. People who work in the field etc too I guess. Though I think a good power bank would be better in quite a few of those cases too.
Enjoy the bike, great hobby.

@thetonyclifton Yep, no question, I could "work around" the issue, with a small/slim power bank type of deal, but the added-battery case, particularly IF it added Qi charging, would be an awesome option to have.
Thanks for the cycling comment, I enjoy it, immensely, riding-fast/skiing-fast (I used to race here, too) are sort of my Zen-moments ;-]
I've also traveled by bike (i.e. loaded touring bike), pretty extensively, which is another (albeit adjunct) use-case for topic at-hand.
Hobbies are a good thing, it's hard to have too many (although my wife might disagree ;-0)...

A good Garmin or similar specific accessory for the bike might cut down on your need for phone use while out there...and be another thing to annoy your wife ?

Yeah, I've considered it, I have an old "Oregon XXX" unit I use, with good base-maps, for loaded touring, but I mostly just pull it out when I'm confused about something on a map, or similar, or I'm looking for someplace to buy groceries ;-]
If the Garmin or another bike GPS ever gets to a "decent enough battery life" (hmm, interesting that this is a cell-battery thread...), say a couple weeks worth, like 30-40 hours of riding, I'd be a lot more interested.
I like the fact that my "good old altimeter bike computer" runs for a solid 12-18 months, on a single coin-cell (wish it were a rechargeable, but that's tough with coin-cells), and just "counts my miles and climbing, basic stats", without fail.
I get a hard-time, in my fast riding group, for being a s/w-h/w engineering guy, but eschewing a "real GPS cycling computer", when darn near everyone else has their fancy Garmin's, or whatever ;-]
I do use an old Suunto Ambit 3 watch, for tracking my weekly riding, but it runs a good 30-40 hours, in "high GPS mode", and 100-120, in "low GPS mode", which is handy for touring, I can easily go a week without having to charge it.
For touring though, it'd have to be a step-up, still (from current GPS units-battery), maybe an ultra-low-GPS-screen-off-mostly "mode", or something like that, so it'd go for at least 5-7 days, without a charge. I'm often camped, and carrying an extra battery for my phone is enough, already, I don't want to carrying more, or even having to charge the GPS every or every-other day, that'd just be annoying, I'm a little more "back to basics" when I'm touring ;-]
I have a decent "general sense of direction", in most cases, and a pretty solid "visual route memory", so unless I'm exploring someplace new, I don't use maps when out riding, much anyway (solo exploring new streets/routes, perhaps), probably comes from years of backpacking and climbing, often off-route stuff, you sort of get a "feel" for how to dead-reckon stuff, or how to pick out a few landmarks, and keep yourself going the "general right way", I guess...
Or I'm a complete weirdo, which is possible, although my daughter seems to have the same sense, when we're bike touring (my wife could get lost in a subdivision though, and would admit to that;-]), she and I are the ones pouring over the map, and pointing at stuff, it's kinda' comical ;-]

Don't think you are a weirdo but think you are destined to be in the niche of a niche for these products ?
You have very unique use scenarios. Basically you need the stuff they give the military ? or for people who live off grid.

thetonyclifton said:
I am genuinely interested in the use scenarios for these in modern phones. Do you travel a lot, need multi day use, play a lot of games, use it as a primary work device or actually talk on your phone a lot? I use my phone an embarrassing amount every day, probably more than I should but would not need something like this. Intrigued by demographic of accessories like this.
I have personally used them in the past but when phones were different.

I currently have an LG V20, which at this point looks like it is going to be the last phone to ever have a removable battery, and switched it to have an 10,800 mAh battery instead (I even ebay'ed a replacement back cover, and man hacked it to have a hole for the new battery, this let the NFC continue working)
I have found that at first I can get about 2 days of normal use out of them when new, but after just a few months, I am getting down to just 20% or so at the end of the day... I prefer to just plug when I go to sleep rather than constantly topping off during the day... I think the original phone would only get me through about 1/3 of my day after just a few months, so I think phones should ship with 10,000 mAh batteries from the factory... I think that Energizer phone has the right idea, just a terrible implementation
Also as I mentioned, I have giant hands, and prefer to have a phone that doesn't feel like it could give me a papercut if I hold it too tight... I like my brick phone

Looks like Zero Lemon has no ETA for producing a case for the 7 Pro, lets hope that changes soon.

@graycatgrayhat Send them a "customer contact message", I did. The more they get, the more likely it is they'll produce one, particularly if they're "teetering" on their decision to make one for the OP7 Pro. Worst, case, you spent 60 seconds filling out a short-form...
Oh yeah, and ask for it to have a Qi coil, in the ZeroLemon pack, I REALLY think that would make this thing sell like hotcakes, given that it adds a LOT more than just a bigger battery runtime (wireless charging, while still having access to the USB port, something that is not really do-able with the current phone, my USB plugged with my cheesy, low-current-but-effective Qi coil, already, and I'd love to have it back...).

Yeah, most of my friends would agree with you, I've been a niche cyclist/explorer, most of my life. My Dad is a geologist, and we spent many times in "odd spots" in various places in Alaska, checking out old mines, surveying new sites, driving HUGE heavy equipment (I drove a D9 Cat when I was 10, across a big river too, and could drive a loader and operate it, by the same age, along with other stuff, backhoes, forklifts and such, I'm definitely "odd").
I would say though, even though my use-cases might be viewed as sort of "fringe", I bet a LOT of people would like to get 2-3+ days, from any of the aforementioned devices, right?
I will say, too, that when I started bike-touring, in the early 90's, I had a little solar-grid, that would recharge AA or AAA batteries, very effectively. It was "ahead of its' time, fully-sealed and all, I still have it somewhere, although I haven't used it for a few years now. It kept my headlamp and the few other batteries I had, back then, charged along my first 5.5 week tour, just bumping along on the back of a pannier...
I sure wish they used AAA and AA (rechargeable) batteries for more devices, these days, you can get REALLY energy-dense models, that last for a LONG time, charges-wise, and then you can simply replace them, eh? Plus, you'd have less problems with a "cheap cell replacement battery from who-knows-where, hoping that it wasn't going to catch fire, the first few times you charge it).
I get that a AAA has a pretty big diameter, for most modern mobiles, but I think it would be close, really close, say in my OnePlus 7 phone, in terms of being able to "just slide in" a set, on one end or something, and still have room for a full rubber seal around the compartment...

Your uses are interesting, bit unusual, not odd just niche which make product development unlikely.
The disposal batteries in a phone are never going to happen. It's not the size of the battery it's the totally empty space needed to fit them in. Phone companies, not even 3rd party accessory manufacturers are also not going to trust degradable batteries with so much room for user error, poor contact connections and poor user practice to hook up to phones with heat and high voltage chargers.

Yeah, maybe. There are phones with >5000 mAh batteries now, although most of those aren't very optimized, to really take advantage of the extra longevity, the ones I've seen anyway.
I still think that people would be "elated", to be able to use their mobiles, full-tilt, for 2-3 days, and still have "enough juice left" to not stress...
I don't mean "disposable batteries", for the AAA, and AA, suggestions, I mean "rechargeable" ones.
It's pretty easy to buy high-quality, 3000+ mAH AA's, and similar AAA's, upwards of 1200 mAH now.
On the other hand, if I order a "random replacement LiIon cell", for my mobile, it's VERY hard to find one, aftermarket, that's of "known good quality", all the battery "re-packagers" have learned to put OEM-looking stamps on them, and even things like the "UL logo"...
Even IF you do manage to find a decent replacement, it's generally a HUGE pain to replace it, involving a lot of very precise cutting (glue around edges), sketchy prying, tugging, pulling, and swearing, trying to get a phone apart "enough", to slot the new battery in...
LiIon is a MUCH more dangerous tech to "get wrong" too, in terms of the line/signal that reports the temperature and charging-state, back to the input line, than NiMH.
Even so, there are also high-quality rechargeable AAA LiIon's out there, too, with even (obviously) higher energy-density, than their NiMH precursors, if you will.
I get that the era of "replaceable LiIon brick-batteries" has probably come/gone, but I think that a "standardized" battery, perhaps the newer AAAA (in NiMH or LiIon), with high-quality cells, at only 8.3mm diameter is "the candidate".
Or, maybe I'm just looking for "a solution without a problem", but I doubt it.
How many people pay some "random cell repair store" say $40-80, plus the cost of an "unknown LiIon brick battery", on a regular basis. I bet almost ALL of those people would be elated, if they could just undo a few screws, buy some decent (Panasonic, Sanyo, etc.) AAA or AAAA cells, pop-them-in, and go back to "full capacity", after 1.5 years of a mobile devices' life, for only say $10-15?
That "seems" like a pretty good, real-world scenario (well beyond my "niche" stuff), IMHO...
Good banter, BTW!
It's always "refreshing" to come over to XDA, from things like the ATT and OnePlus forums. There are some sharp people, who know the industry, on those boards, too, but "less so", on average ;-]
If I were writing much code anymore, I'd probably spend a lot more time on XDA, but I've moved over to the "evil Tech-PM" type of roles, although I am "that PM" who often jumps in and starts debugging stuff, or signs off on a code-review for check-in, which is sometimes appreciated, and sometimes just annoys people, it depends on the team(s) I'm working with...
What I"m really aiming for, is to find a tech-PM role that's mostly remote; I have a bad nerve injury, that prevents me from sitting or standing for any length of continuous time (although I can still put in a 2-3 hour ride, it's a "nerve neutral" position, for me, for about that length of time), so it's a "weird deal" to be a PM who's always "pacing around" meetings, even if I'm not presenting (presenting can make it easier, to stand-up/sit-down). I'm perfectly eligible for disability, although I just don't ever see that happening, I'm way too driven ;-]
I could probably be a moderator, in many places, but I like to "bring teams together" on tech-issues, even down to the individual-interface level (API, whatever), I find that much more satisfying, professionally, than doing "policing" ;-]

@pgrey2
I think the answer is actually in your narrative. Exactly because people will make ropey versions of replaceable batteries and in so doing make them more dangerous. Because the phone manufacturers lose the control over their phones exploding when that is someone else fault. And because replacing batteries even with great, safe after market versions will prolong the life of a device which they want you to replace every couple of years. It won't happen. People will love to have 2-3 day battery life and it might happen but so far the new features of a phone have been draining batteries at the same rate as their capacity, size and cost improvements have been made.
Good luck with the job. Sounds like you know what you want and what will work for you. I assume you live in the US. I don't. We have a welfare state and laws which (relatively speaking) protect people with disabilities a bit better. You should be able to work the amount you can and be helped to do so for as long as possible.

I bought the OnePlus 7 pro then realized there was no battery case. The current battery won't last. I hope zero ? will make one but not too bulky. This phone is great but the down size is it's battery size.

Newdery perhaps???????
Newdery. A brand I no almost nothing about. While searching for Oneplus 7 Pro battery case this brand popped up on amazon. I'd really love to give you the link but as a new person I cannot. Search Newdery Oneplus 7 Pro. Or just Oneplus 7 Pro battery case. You'll run into a few, but no lemon.
I came across the Newdery brand one over the weekend on ebay really cheap in new condition. Still haven't received it yet. Well I'll try and report back. If anyone still cares that is.....

There actually is a shimmer of hope. That hope comes in the form of the Oneplus 7T Pro. That and the 7 Pro have the exact same body style and fit like a glove. Maybe all this added attention might bring about a style battery case that will fit them both.
One thing to note is the (IR) laser autofocus rangefinder on the 7T is on the left of the lenses, on the rear of the phone. So you won't have any problem getting a 7T case fitting the 7 Pro. But if you have a 7T you can't use a 7 Pro case properly. Unless your willing to cut a whole I suppose.
