[Q] Battery empty issue - ZenFone 2 Q&A, Help & Troubleshooting

Good day everyone.
i just bought my zenfone 2 551 2gb 16 variant at Lazada PH. i've been using if for like a week now. the problem is when the battery goes to completely 0% i can't turn on the device during charging. my other device can be turned on from the moment i plug it in. this device have to be connected from about 15 minutes before it can be turned on... any idea what the problem is?

That's normal with all the zenfone 2 devices, it needs a certain amount of power before it can turn back on properly

Usually waiting for 2-5 minutes of charging while off will provide enough power to turn on the device.

thank you for responding.
well if that's the case then i'm relived.
but initially i email the support team of ASUS and got this response from them:

Dear SquallDNA,
Actually this is normal for Zenfone 2. When 0% charge you will need to charge for a longer period before being able to turn back on. Also ZenFone 2 Intel 1.8GHz 2GB DDR3 16GB does not come equipped with 18w Boostmaster adapter and will require longer charge. Only the 2.3GHz 4GB DDR3 64GB comes with 18w Boostmaster adapter: http://www.asus.com/us/support/Sear...5-480F-AADA-FE49EDD81C01/?keyword=boostmaster

Thank you for responding. but it just seem abnormal. cause i have a cheap device that doesn't do this same issue. from battery empty stat, once i plug it in, even with a usb port, it immediately turns on with no problem... i guess you can actually fix this with a firmware upgrade by fooling the device from completely turning off the unit even before 0%.. this could be a life saving matter. i hope you understand what im saying. as of writing this reply, my phone went from totally empty at 6:13am. charged it. still can't turn it on by 6:30. somebody could have robbed and killed me in my room. i could've called 911 already..
finally, it turned on at 6:40am.
please consider my suggestion about firmware upgrade. im not a programmer but i know this could be done..
thank you so much.

No offense but wouldn't it just be easier to put ur phone the charge before it reaches 0%?.. I mean the same effort to escape murder could simply be put into plugging in ur charger at 1% instead.. it's that simple..
The scenario seems more of an excuse for being lazy IMO
To each his own i guess..

no offense taken. but in the instance that i forgot to charge the device, extended travel, or usb port is not available. that happens right? and then emergency came knocking your door.it's not an excuse for laziness, it could be for negligence but not laziness. again things like this happens. and besides c'mon, it's ASUS. not any cheap chinese low quality device(no offense). almost 30 mins of not being able to use your phone.

FYI , it happens exactly with Iphone phones.

wow really? that's ridiculous then. sony xperia, PIPO tabs, and myphone brands doesn't do that, based on my personal experience. well i guess nothin's perfect.

It is really not good to discharge your battery to zero on a regular basis. Never let it get below 10%.

Pls post screenshots of battery usage nd screen on time of zenfone 2

[REQ] We need a Fast Charge Battery Driver

Like most of the others in this section, I come from the WinMo world. I just got my OTA'd Evo and I have to say, the battery takes forever to charge. My Touch Pro2 & Touch Pro both have no2chem's fast charge battery driver(it makes it feel like they fully charge in 5 mins) and since we haven't seen him in a while I thought someone else might be able to develop one for our amazing Evo's!!
Please Help!! Thanks in advance!!
Can you provide more info on this? A full charge in 5 minutes sounds ridiculous but I won't out anything past XDA

this has been spoken of before on these forums... it might be in the works, but you are reffering to a fast charge via USB connection rather than wall connection. Wall connection is full speed, USB is throttled down to prevent damage to the USB port on the computer plugged in to.
the process is a great add if you use tether charge a lot, like I do. If I am constantly streaming online on my old winmo phone even with fast charge I would slowly deplete my battery while it was plugged in, I haven't used the EVO much for streaming but I would be afraid to see the results w/o fastcharge.
thats why you buy a couple extra batteries and a wall charger

This. Got a replacement battery and charger on ebay for under $10 shipped. Works out great. Just swap the generic out with the stock whenever my battery starts running low. The only time I ever plug in my phone to charge is at night.
Seriously - if somebody is requesting a valuable piece of development in a development forum, what value are you adding trying to sell him batteries!? Do you honestly think he's gonna be like, "Oh hey, yeah, you're right! Who needs a phone to charge fast when I can just carry around a pocket full of spare batteries and a charger! Why didn't I think of that?"

Perhaps he didn't realize how inexpensively good-quality replacement batteries and chargers can be acquired. Also, a single battery inside a charger case isn't much larger than a wall charger + cable (which by your own assumption he must be carrying around in his pocket).
I understand what you're saying about it being a developer forum and all, but I don't see any harm in offering a feasible solution to a posed problem. I mean, look at Apple. They told people they had to buy a case or stop holding a phone with their left hands!
+1 for this
5 Minutes to charge and 10 minutes of use sounds about right for WiMo
I wish when connect to USB it would trickle charge. that way you don't the drop as soon as you disconnect the phone. so i guess i want to slow things down a bit but just when on USB.
This!

Yes, we need this for sure! Carrying around batteries is NOT the answer.
it wouldn't really charge in 5 minutes, but it would charge about as fast as plugging it into the wall.

this fast charge thing is NOT new to most of us that frequent XDA and other dev/mod forums (PPCGeeks)...and it is perfectly legit to put out a request for...
suggesting an extra battery is good and all...but not always feasible. Apple suggesting what they did was to redirect everyone's attention to THEIR lack of attention on a piece of supposedly high end hardware..that now seems to be flawed. OP has been around for sometime...and the extra battery thing is a good idea already...especially for noobs

[Q]

I have a Samsung Galaxy S2 and for some reason, the battery is draining fast at times and I have no clue why. Could it be a software issue? Lockscreen Issue? Whenever I have my phone hooked up and charging, sometimes it profusely keeps charging then stops charging and vibrating thousands of times. I'm thinking about doing a factory reset, any app that can backup all of my data to an SD card?
The only apps I'm using are facebook, chomp sms, magiclocker(theme), music, simple notepad, juice defender, kik, and magicjack.
This started happeneing about 3 days ago and its frustrating me when my phones dead and I have to call someone.
Please help,
Thanks
Just turned it off and back on, battery was at 50% now its at 25%...
System info. What you have done info. Then some one will help I should think mate :thumbup:

Its an SPH-D710, I havent modified the phone at all.
Thing is, everytime I hook up the charger to it, and it keeps charging on and off on and off on and off. It gets irritating and makes me want to throw this thing at the wall. Could it be the charging port?

Yes. This. I've asked mods to move it seeing as nobody else did.
You also mentioned that your battery is losing charge quickly, pull it out and try spinning it on a flat surface.
If it spins, then the battery may be going bad. There are a few options at this point, but I'd recommend ordering a new battery that has a larger capacity. There are several available on both Amazon and eBay.
I purchased a 3800 mAh battery with back plate for less than twenty bucks and my phone now lasts all day with heavy use. On top of that, I don't have to charge it as often, so there is less risk to my charging port.
Good luck!

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.

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!!!
rdgs
H.
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.
Sent from my Droid Turbo 64GB BN
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.

[Q] Rooted Motherboard Issues?

Knowing that this is my last resort and with all the wonderful knowledge here on the forums, I'm hoping I might get some creative ideas.
I recently bought a Tab S 8.4, rooted it about 2 weeks after I got it. No problems, everything is working great. Last week, the screen starts to flicker and the tablet reboots randomly. When it does this, the battery goes from 100% down to 12%. Eventually this happens enough where the tablet won't stay on for longer than a minute. Read around the forums and find others mention the exact same issue. Potentially a battery pull/re-plug may alleviate. Tried that to no avail.
I have found that if I hold the battery plug in place *real* tight, by pushing down with my finger, the tablet operates somewhat normally. Could be a motherboard issue.
Anyone run into this at all? Thoughts? Ideas? Replacement parts? I've got a $500 brick on my hands now with no warranty to boot. :crying:
Thanks in advance!
I soldered my battery straight to the board. But before doing that, try spraying some contact cleaner (found in hardware stores) and see if it Will work

I found a local electronic repair shop that said they could re-solder it for me relatively easily. Brought it in and he said it did look like the terminals on the battery plug had been pulled back a little bit and weren't soldered on there very good (good to hear some type of confirmation on that and he let me view it through a microscope as well). Twenty minutes and twenty dollars later, my tablet is working as it did previously. I've used it sparingly over the last 2 hours, so nothing definitive yet, but the fact that it doesn't restart right away makes me think the issue is resolved.
Thanks everyone for the suggestions!!

Battery Results
Just wanted to follow up with everyone that might be experiencing similar issues. After fixing the issue, and de-bloating a bit, my battery life is phenomenal. Much better than when I first got it. I suspect the battery issue was causing some drain as well, even when it wasn't restarting. The attached screen is still with 35% battery left.
Thanks to all those who contributed to this thread. I too was having battery issues. I'd get random restarts, disconnects from the cellular network, forgetting wifi passwords, battery that would go from 50% to dead in three seconds., display glitches etc. I finally opened up my tab which I thought was going to be a pain but was actually pretty easy. By naked eye the solder joints looked fine but under a microscope I could see that all six solder joints on the battery connector were cracked and by pressing on the connector could see the connector move independently from the PCB. Resoldered the joints and everything is good now.
Well my problem is that the battery isn't charging, I get a battery with a red "X" mark when the screen is on but when it is turned off, its charging well but very slow and when it reaches 99% it never goes to 100%. Could it be possible I have the same problem as you guys? no random restarts for me just the issue of sucky battery life (3 hours on wifi) and not charging

Are you using the stock Samsung charger? Just plug it into the wall and it should be fine. Don't charge from the computer or use a different charger
Got that same problem. My tab will only charge up to 60% under 6 hours. Batterystatus app shows that my 2amp wall charger is just charging at 300mah +/- . Tried my power bank, same issue. Changed the cable and the reading from the wall charger is 1800mAh , could top up the battery in 2hrs

Using wall charger. Never charged via pc...
Any Ideas?
I have experienced this. Flickering of the screen which eventually leads to reboots. Got it fixed at a samsung service center. You rooted it but you're on stock ROM right? I think there's a problem when we root it and stick with the stock ROM. When I rooted my tab again, certain apps started FCing which lead to lags. So I'm gonna wipe this and start from scratch.

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.

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
>>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.
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. 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.
