sm-t210 wont boot or charge - Galaxy Tab 3 Q&A, Help & Troubleshooting

as above i know your not supposed to fully drain this tab, but am getting frustrated as my son never charges it when low. so the only thing is to keep taking cover off and disconecting the battery.
has there been a fix for this bug?.
thanks
ps i have always had android, the mrs and kids have apple so am coping a bit of **** over it

Yes, the bug has been found and fix. The bug was a lackadaisical one. Worst type of bug in the technology world. Sorry to be so harsh on you, but you found your problem and the solution is to plug it in at night. Now, there is one thing that is certain and that is you use the OEM charger and cable to charge the device. Do not use Apple or a third party charger unless it meets or exceeds the specifications of the OEM charger (the charger that came with the tab).
If you use a smaller rated charger it may not work or will take forever to charge your device.
Next, take the device away from your son as he has no responsibility to maintain it. Again, sorry for being so harsh on you. Kids and expensive technology do not mix.
Also, did you or your son try to root and install one of these roms you can find here? I have seen several posts that have the same issue as you and the catalyst was rooting and loading a rom other than the OEM Rom for your device.

[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

Haha, I remember that WM driver..NueBattery (no2chem)..

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.
and for the person mentioning the developer who was a girl, cmonex legend of hardspl!

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

DEAD battery? (won't charge) - read this

I am posting this for three reasons:
I want to offer hope to people who may otherwise run out and spend $40 at retail B&M to get a battery.
I want to raise awareness about an issue that likely has some dev contribution to it.
I did a search in all the Evo forums here for posts with "dead" "battery" and "charge" and didn't readily see this information provided.
So here is the "secret" - the charger HTC supplies when you buy your phone provides more amperage than many other chargers. It provides 1A, whereas most others supply 950mA or less, and even non-OEM ones which say 1A do not usually provide it (I know, I have some). I learned this years ago when the HTC Wizards would go completely dead and the only thing that could revive them was the stock charger.
This still applies today, even to the Evo. Night before last I went to bed and my phone was plugged via USB into a plugged in PC as it has been dozens of times before and when I woke up it was dead and would not power on. No other charger, wall or USB would work, and I was traveling so I didn't have mine. A trip to the Sprint store confirmed my phone would power on with another battery. When I got home last night I plugged into my HTC charger and within 10 seconds the light was blinking, and it was solid within 30 seconds. Now it is "fine again", but needless to say I have a backup on the way from Ebay.
Now to why I posted this in Dev, and why I think it should stay here and not in general. Here is what I was running:
MikFroyo 4.4 (upgraded from 4.3, no wipe)
Netarchy 4.2.1 cfs havs more universal (forgot to check whether SBC or not, but I know I have run SBC and MORE kernels before for a couple days at least with no issues)
Launch day Evo, hardware 003
I think if mods move this to General then many fewer devs will see it, and I do think the SBC kernel probably played a role in this thing dying. I am NOT trying to blame the SBC dev for anything - this is all my responsibility, but if others have this problem and report ROM, wipe status, hardware rev, and kernel in this thread, maybe we can isolate what causes the problem. Regardless of what is decided, everyone who flashes should know about the charger issue so I hope this helps some folks.
Mark
I've owned a Diamond, a Touch Pro, Touch Pro 2 (x2), and an EVO. They ALL came with the 1A charger. I've NEVER had a battery die.
I've also used SBC, and although it provides substantial battery life, I removed it due to the fact that LI-Ion batteries are not supposed to be HELD at a 4.2V charge. But that's beside the point here...
The point is HTC Chargers have been this way for quite some time and being phone manufacturers for 14 years, I think they have sufficient evidence that their ways work. They wouldn't put out a 1A charger if it was known for killing batteries. After 13 years and collecting feedback about them all, if this was a problem, they would have provided a different charger.
You simply got a bad egg. It happens. Batteries are known for getting bad ones every now and again.
This also does NOT belong in the development forum... because there's nothing developers can do for a defective battery, and even if there was it still wouldn't belong here, because it's a request/question. (Can you do this for me/us?)
This belongs in the Q/A section.

This is all well and good but not useful. My post was not to say my charger (or any charger killed my battery), my post clearly said my software MAY have killed the battery and that only a 1A charger, which is what HTC supplies, revived it. I have had it happen 3 times, over 5 years and thousand of flashes so it doesn't surprise me you haven't seen it as most wouldn't. Clearly some combinations of roms/kernels/hardware (including batteries and their revs here) cause it, but when it happens to you it can be a royal PITA. Anyway, I have a dozen other chargers here from Motorola, Nokia, RIM and non-OEM which prove that your info about other manufacturers supplying 1A chargers to be wrong, so maybe you should read and investigate before you thread crap.

Very well, I skimmed over your original post, and it looked like from a glance, that you were saying that the 1A charger caused it, my mistake.
However, I never said that other manufacturers supply 1A chargers, I said that HTC does, so perhaps you should take your own advice and read.
Secondly, You presume to think for some reason that I have not done any REAL flashing/experimenting. You are incorrect. Being the owner of several HTC devices, I too have done thousands of flashes, both experimental and non-experimental. I also built my own roms and kernels for all the devices I specified. And I have NEVER had a problem with a battery failure caused by software issues. I did have ONE issue, but I caused the issue, I charged a battery with NO built in software/hardware protection, and killed it by leaving it on the charger without protection, which was my fault. (hence the second Touch Pro 2)
Thirdly, There have been a total of what... 8 or 9 battery failures reported now? (Granted this does not include those that have NOT reported on the forums that it died...) Now, I'm no expert, but in terms of statistics, in the minds of the manufacturer of products that are designed KNOWING that they are going to fail at some point or another, And dealing with naturally unstable elements inherent to the design aspect of the product, I would think that this is an acceptable number compared to the total number of batteries sold for this specific device.
Nope, presumed nothing. Even with dozens or hundreds of flashes you may not see this, especially with WinMo phones as I noted you listed 3, and so what I said was correct. You did note your phones came with HTC wall chargers, but that was irrelevant. I was talking to the vast majority of chargers of all types, which many of us have and use in addition to our HTC wall chargers (as I was, because I was traveling). And your last point, again, is off the mark. As you note, for every report of an issue there are many times more folks with actual issues who for whatever reason don't note them (in my experience, usually because we're all too busy). But I've taken some of my valuable time to try to help the dozens or hundreds of folks (including non-Evo folks who may search XDA or Google and see this) who actually have this problem. Anyway, I've wasted more than even time on you, so reply all you like, I'm done with this debate.

Holding the charge at 4.2 V is not an issue, and most kemels will do this. The "issue" is with the continuous movement of Li ions towards the anode even in low amperes. However, thus far the evidence and data presented behind the catastrophic failure caused by Li plating - is somewhat lacking.
Furthermore, I think its BS when someone with little knowledge on the subject reaches to blame SBC as soon as something goes wrong with their battery. I suppose its nice to have a scapegoat ...
Tapa tapa tapa
It's funny you should post this because this just happened to me....like it happened yesterday. I rooted my roommate's phone and the next morning his phone wouldn't turn on or charge with any charger, etc. I knew it had to have been a problem with the battery because I'm sure it wasn't something I had done like bricking the phone, so I switched his battery with mine and...his phone worked. Maybe it was a faulty battery or maybe I DID do something wrong but it was weird because all I did was flash CM and I didn't use any SBC/HAVS kernels. Either way seeing this post and what happened to my friend's phone has me a bit wary of the EVO's battery...but hey we all know the risks here so the lesson learned is...research before anything lol.
This is no secret, really.
It's just a common misconception that all USB chargers work the same.
USB 2.0 standard is 500mA+, and specifications allow USB 2.0 chargers to go up to 1.8A (1800mA).
USB 3.0 specifies a primary port to have 900mA, so charging your phone on a USB 3.0 port (laptop/computer) is recommended over USB 2.0.
Many smartphone chargers (stock) provide 1A, while many 3rd party chargers still use the typical 500mA.
ALSO, it should be noted that when a devices battery (if it is lithium-based) falls below a certain voltage, the device typically will not attempt to charge it for safety reasons (it causes oxidation which can cause physical damage and in worst scenarios the battery will explode).
Also, don't blame SBC...while I'm not a fan and it's arguable it can cause battery damage, this is solely a USER-ERROR (that means you made the mistake, not your phone, not your phone's software)!
Still think this should be in the general forum. Although I did "develop" a headache from reading all the big words, so maybe it can stay.
1 month after getting my Evo(2days after the Evo was released is my start date) ,my battery took a crap. I was unrooted. I rooted in July , I've run many roms and kernels since. I have been running SBC with not one problem unless you consider fantastic battery life an issue . I've been runening SBC since it came out and I'm an extremely heavy user.

The reason I called it a "secret" (not the quotes) is that many non-OEM chargers listed as 1A - aren't. I have 3 others here that show 1A that don't work (haven't plugged into a multimeter to see what they are actually putting out.
Also, to the poster who said this is the user's fault and not SBC's let me be clear (again, as I was in the first post) - I take absolute responsibility for whatever happens when I flash my phone with non stock software. Further, I am not blaming SBC, just mentioned I MAY have been running it at the time. That said, the phone had a charge and was plugged in to the same chargers it has operated on dozens of times before and again is operating on now that it has been revived, so there is SOME software or hardware issue here. Saying it is my fault, beyond the fact that I flashed something unauthorized, is patently ridiculous. Just want to be clear that taking responsibility for risk and understanding the related consequences is one thing, but being blamed in totality for all consequences is something else altogether.
So, to prevent this from turning into a blame SBC thread, I'd ask that anyone who isn't experiencing problems, or is, but hasn't had a completely dead battery, post in the SBC kernel thread, because they are doing great work over there.

You may not have tested, but you also aren't listing the stated voltages.
Input voltage can sometimes be used for reference, which can also explain some issues you are having.
This has turned into some big "secret" when all it really is happens to be you finding the fact that non-OEM products often have more quality issues and also higher margins of error.
Many people may not know this, but the way you have gone about this thread is what me and others are objecting. Why you even mentioned SBC as if it had something to do with this is also a big issues, considering there is much controversy over SBC kernels.
You have to understand there are proper ways of presenting information and findings, and this is not one of them...you came here presenting the presumption that this is a dev issue (in some aspects pointing fingers) when this is far from that.
I mean, I hope you understand the way you mentioned SBC insinuates SBC has something to do with this...
Your charging port might be going bad.
Um, no, and it's not. Read into it all you like, there are EE's who will argue on both sides of the SBC discussion and frankly I don't care - I an running another SBC kernel right now. I do know it is happening to people and just because I knew the HTC charger would fix it and you may have known it doesn't mean the majority of others do.

One thing I learned with the 25+ android phones I have had and the many years already using android is phones die according to the user wether battery,bricks or just the phone not performing like it should. I use and mod my phone the proper way and have never had issues unless I F-ed it up my self and a few factory issues I noticed a hour or so after opening the phone. I also have used a bunch of kernals and have been using SBC kernals since they started appearing on the seen and have yet to see one issue but then again from the years of my modding experience on phones in general I never buy extended batterys because they have always caused issues also I never use 10 dollar batterys or any charger that did not come with the phone.
So I think this thread is give or take based on the user and what they are doing with there phone, but not saying its not a issue.
I am a Sprint service tech. This type of "failure" is common and is not exclusive to the Evo. An undercharged battery will often refuse to respond. Generally leaving the device plugged into the wall with your OEM charger will eventually trigger a charge. Your local Sprint ASC or Retail service center can jump start a "dead" battery with there Cadex.
Newer cell batteries very rarely die or fail.
Exactly what I was trying to say.
My last few comments on this:
I came here to help some folks. I knew the resolution to my issue, but we shouldn't assume everyone does. In fact anecdotally I would say MOST people who come here want to know just enough to flash ROMs or tweak their phone to address some major irritation or reap some benefit their provider doesn't give them, but they don't care about these "corner cases". And although some will disagree with me, I don't believe that this limit to their desire for knowledge means they don't have a right to be here and shouldn't be flashing.
In the end I came here to offer up help for a real problem. I disagree with anyone who says there is no software involvement here and with the statement that this is somehow user error (unless one believes letting your battery get below 20% or plugging into a non-OEM charger is user error). Clearly it happens, there are theories as to why it is happening and no one should squelch those. I've seen a lot of people leave this board for others recently for exactly that reason - people here are too quick to weigh in with their opinion or thread crap and this is one of the reasons this board has become progressively less helpful as of late. I think this sucks, but I am not starving for approval, so move this thread, lock it, let it fall into page 10 obscurity or whatever, I don't care.
This is still a debate. I had my moments with SBC kernels and I associated it to those SBC related kernels. I did my test twice and both times the SBC kernels with USB - PC charge would cause my battery to die. Also without the HTC OEM Wall Charger it would not work. I kick started it with the HTC OEM Wall Charger and cable. Even a non-oem cable that I have used for everything doesn't work to kick start it.
My experience for my phone is to stay away from the SBC Kernels. This is regarding dead battery/non-responsive phone.
I have had some of the older non-SBC kernels not charge my phone with a Wall Charger (HTC) to past 65%.
So who knows it sometimes is a crap shoot.

[Q] Note 8.0 won't start... period. May be hard bricked.

A while back i used to "try" to root stuff. I sucked at it BAD. Anyway, I have a Galaxy Note 8.0 (GT-N5110) that I had rooted to a certain point (very superficial) and I just kept it the way it was, that way I could use Multi-window for any app. This morning I unplug my tab from the charger only to be disappointed that it will not turn on. Ive tried different power outlets, different cables, different base chargers, even the whole "power+vol_up+home" thing... nothing. I never updated the tab when Kitkat came through the pipeline. Im freaking out that a new major update automatically happened overnight or something. Im sorry to trouble you all, but does anyone have suggestions? Since it's rooted I can't take it to Samsung or Best Buy. Honestly if I could just get it back to stock, that would be awesome, but im more concerned about getting it to simply turn on. Any Ideas?
If your device is rooted you won't get an OTA update so that could not be the problem. You can try to unplug battery (mus open the device)"and see what happened. Maybe your battery is faulty or someting else.
K... I appreciate it Ill take a look. But, lets say I actually open it (without making things worse), how do I determine if the battery is in fact faulty? If it is, can I get a replacement? preferably an official samsung one.
EDIT:
Scratch that. Sry, Im just always scared of doin stuff, so I always feel like I have to ask the question, but I'll look it up. Im confident at least this should be easy enough for me to do Thank you again.
The problem with this device is you cannot pull out the battery easily. Maybe after that steps it boots up again.
Battery removal wasn't bad... now I'm just waiting for a new one (ordered on ebay, crossing fingers hoping it was legit). What did you mean "after that steps it boots up agin."? Will the tablet boot up without the battery if it's plugged in or something?

Wow, that suck. sorry for you man. For now, try to plug the tablet to a computer and while device manager opened and see if there is change. If the change say "qhsusb" or something along that line and not your model number . . . changing battery wont do anything because it's already hard bricked. if not, finger cross.

No. But sometimes after this step and reconnecting the battery the device boots up. Also a battery calibration is done.
I tried plugging in the tablet to the computer with the old battery and then without any battery. Neither one prompted anything in the device manager. Today I got the new battery (assuming its legit and in good condition) in the mail. I plugged it in, and nothing. Plugged the tablet with the new battery to the wall charger, nothing. Plugged the tablet with the new battery to the computer while running device manager, nothing.
I'm going assume that the new battery is dead and let it stay connected to the wall charger for 8+ hrs, and see if there are any changes.
I just really don't understand what the deal is and why this would randomly happen. Ive never had problems with the firmware or anything. I have felt like there was an issue with the battery being that it doesn't seem to be keeping much of a charge... but for it to just Hard Brick like this seems so out of the blue. Can anyone provide me with additional suggestions please?
Maybe I'll ask it this way...
Is there any way to test if the batteries are food? That way I can at least determine if the tablet is in fact hard bricked or just bad batteries.
Might not be what you want to hear, but if different cables, chargers and batteries don't work, then maybe there was a power surge overnight while the device was plugged into the wall that took out the device (I once lost a computer that way and now I only use surge suppressors (note that not all power bars are proper surge protectors! See here: http://en.wikipedia.org/wiki/Surge_protector ) that are UL 1449 certified with a low clamping voltage and high energy absorption rating as a minimum; the fancier ones can even tell you if your wall outlet has a grounding problem). Or your tablet's USB port is broken, but that doesn't make sense based on what you've said thus far. Or you're just super-unlucky and all of your replacement parts are also faulty (it could happen). Either way, I've got my fingers crossed for you!
In the meantime, a multimeter would be able to tell if the batteries hold a charge, and whether or not power flows to the device when the battery is attached or the device is plugged into the wall or computer.
Just make sure you read up on how to use one first so you don't accidentally electrocute yourself:

Ill definitely be looking into this option in depth tomorrow, and deeply appreciate it. At least it's something. T_T I don't want my tablet going to electro grave. This sucks so bad. This has been a month from hell
First my printer decides its time to start printing crooked over a couple of months, getting so bad that it jams up a few weeks ago, requiring me to get a new printer, which has been a fiasco in and of itself that still hasnt been resolved. Ive gone through 4 printers in one week, all of them different model printers, all from HP, and each and every one of them defective.
Then my laptops video card tweaks out because of installing Splashtop Stream, which starts a domino effect requiring me to do a factory reset on the laptop.
Then my Tablet just decides to kill over.
Then my Microsoft Arc mouse decides it doesn't the want to wheel to work requiring me to purchase a new one, and when I receive it, the cover for the battery compartment is missing and the wheel click is defective. It took 2 and a half weeks to resolve
Then I get bronchitis.
all in less than a month.
Alright, ya... it's dead. Oh well. Here's me trying to make the most of it: are there any places that buy bricked tabs? I figure the parts have to have some sort of salvage value.... maybe.
You can't go to a Samsung service shop? They might not fix it under warranty, but I assume they'll have a look at it and give you an estimation? I feel for you, we all have had these awful weeks... I soft bricked my pad, my computer started to play up, my other computer decided it wanted to die after years of hard work and not skipping a beat, my son got the flu, the missus was on her monthly(grumpy wife..take cover), and when I took a break from it all on the toilet I found that we had run out of paper! To make matters worse, my favorite football team lost from a second division team.. This all happened in one single day! So chin up, it might take a week, but when all it's fixed again you'll experience deep appreciation for the things you have taken for granted.... (xda fixed my tablet, time fixed my wife)

Sry for delayed response.
Im very very doubtful that Samsung will help. I have two more... ideas, before I go to Samsung. Non-invasive of coarse, wouldn't want to make matters worse.
K, So first off I took the tablet with extra battery to a tech place in the area that said the batteries are fine, but when they put a multimeter to the motherboard nothing came back. Basically its dead according to them. There's one more shop in the area I want to get a second opinion from. Next, does anyone know anything about an app called "Splashtop Stream"? I'm a fond user of Splashtop to control/view my computer straight my tablet, but when I installed "Splashtop Stream" to use the tablet as an extended screen (not just a cloned second screen), my tablet and both computers I tried it with did NOT like it. I immediately uninstalled it, but it dawned on me that it was just a matter of days later that my Tablet died. I hate to grasp at straws, but if an app like that is too resource intensive, I'm okay with seeing a connection that it fried my tablet. I can't just ask Splashtop "Hey, does your app fry motherboards", so I need a way of researching legitimate known problems. I can't afford a $400 tablet right now.
The reason why I'm using Samsung as a last resort is because it's outside my warranty time, and the moment they know that I did even the simple fast-mod on it, they'll slap it down and won't help. There no custom boot or Roms on it.
With all this said, any suggestions anyone?

I randomly bumped here and I'm no expert, but if your tablet's motherboard is indeed dead, I believe there is absolutely no way they can tell that the device got rooted at some point. You did not "hard brick" it, that's a whole other thing, or at least so I've learned in my not-very-long experience. "Hard brick" should be the result of flashing a kernel made some other device, which definitely is not your case. Moreover, that does not kill the motherboard, it just makes anything unbootable: it's a software problem, so it can actually be detected. You had a hardware failure that most likely completely wiped any proof that you have ever modified your device, so the only problem that you might have, I think, is them telling you that they take no responsibility for what your power outlet has done to the device, but they shouldn't be able to detect any modification that you have made. In my opinion technical support is worth trying.
Awesome!! Thank you so much!

Just thought Id let everyone know that I managed to get Samsung to compromise on the matter since the Tablet is only 5 months past warranty (1yr 5mnths since purchase). So, not much longer and hopefully Ill have a tablet that works yet again.

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.

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.

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.
