So I was charging my phone last night and it was under my pillow on airplane mode as usual, because I use it to track my sleep patterns. But this morning I woke up phone was off, with the charging battery icon showing only, and was so hot to the touch I literally couldn't even pick up the phone. I was really surprised it didn't melt or start a fire, that's how hot it was.
Now today after letting the phone cool down, it doesn't seem to be taking charge well at all, I'm having a very hard time getting past 25%, if I use the device while charging it will actually drop charge while in use (and this is with the wall charger).
I'm thinking the battery cells have been damaged by extreme heat. but just wondering if anybody else had the phone get this hot?
Sounds like damage to me! Sorry to hear that man.
Also seems like an irreversible damage to me :/
Some day I accidentaly left my LG GT540 letting it charge under my pillow. It got EXTREMELY hot and I unplugged it swiftly; I was so frightened that the battery (Li-Ion!) might have literally blown up.
To be honest, you should be grateful that your pillow didn't catch on fire together with your head, really... NEVER EVER LEAVE YOUR PHONE CHARGING UNDER ANY PILLOWS!
Well guys funny thing is, seems to be charging ok now.
I believe I'm having a similar problem that a lot of other people are having with the phone getting stuck on USB charging mode even with the wall adapter, so not accepting ACpower. But once I reconnected it a few times now its charing on AC and got back up towards 70%, so I think luckily I might be ok.
But damn this phone gets so much hotter than the galaxy nexus.
My phone never gets hot when charging...ever. I think you might have an issue with your phone
Recently I purchased my first tablet, ofcourse the Nexus 7 32 GB and I am very happy with it.
As soon as I started it, I received the notice that an update was ready to be installed, which I did (4.2).
After that I got another notice to install 4.2.1.
So far so good, everything worked very well....also the normal charging with stock charger and cable.
Then after about 1.5 weeks I noticed that my battery level didn't went down from 100% to xx%, even after playing games for several hours.
I am absolutely sure this wasn't the case before, I did charge well and battery-level went down normally.
So because I couldn't tell if the battery was empty or not (because it kept being on 100%), the Nexus went down ofcourse.
Well, I plugged in the stock charger and cable and started to charge it.
Battery icon (when Nexus is off) nicely went from first quarter (25%) to full (100%) when I unplugged it.
It booted up nicely, but then I noticed that the battery-level showed 0% and kept stating 0%. Even again after playing games for several hours (GTA4 and RR2).
Normally it should decrease in battery-level ofcourse.
So now I'm stuck at battery-level 0%, but strange thing is that the Nexus works fine besides this small problem.
I can charge it, play with it for several hours, reboot, deplete the battery, etc....
Only thing is I can't see the actual battery-level which is very annoying, since I never know when the battery is empty and needs to be recharged.
I searched internet using Google and also here on XDA, but never found a solution.
What I already did was :
1. Reflash stock ROM, using the Nexus Root Toolkit.
2. Flash CM 10.1 with CWM Touch
3. Tried to hold down POWER + VOL UP + VOL DOWN for 30 seconds
4. Tried POWER + VOL UP
Nothing I did worked.
Did someone had this problem before and was able to solve it ?

Hi,
I had this issue too when i purchased my nexus 7.
For solve the probleme I've remove the back of the tablette then unplug and replug the battery.
Don't had any other issue. its realy a nice tablette you have make a good choice.
Sounds like a problem with the fuel gauge chip... Not sure if you can fix it.

Try fully charging with power off then deleting your battery stats file...

That file only stores the data used to fill the battery graph... It has nothing to do with the actual calculation of battery percentage.

Oh well, was just an idea.. Thanks for enlightening though..

Check out this thread, there's people talking of a fix for PA for battery percentage stuck at 100%.. Maybe the same cause as your problem... Look from post #10047 onwards.. Makes me think its probably not a hardware issue at least.

In PA, is definitely a software issue and seems to be caused by paprefs. The issue that is commonly reported with the N7 across all roms is typically caused by the battery connector not being properly seated. Asus QC consistently has fallen short on this connector.

I have fixed multiple loose battery connectors using clear scotch tape. The problem is that they didnt use any adhesive on the battery for a batch of n7`s. Makes it possible for the battery to slide back and forth at least 5mm. When it does it pulls the internal battery lead right off the mother board connector. Tape the connector tight. Then tape the battery to that side. Do NOT tape over the copper tape. I even made a small strip of foam to place along the far side of the battery to remove the room to slide.
Easy fix for an annoying problem.

I can surely try to open the back and check if the battery cable is seated correctly, but I'm wondering....
If it isn't seated correctly, wouldn't that mean that the battery isn't charged at all ?
In my case the battery is being charged and depleted normally, since I can use the N7 to play games etc.
Only the battery-level indicator keeps telling me the level is at 0% and it says "unknown".
It's just annoying as I don't know when it's fully charged or fully drained.
Now I let it charge for a complete night and work with the tablet untill it dies on me.
Just to let everyone know, who might face the same problem :
I pulled off the back cover and found out that indeed the connector, coming from the battery going to the mainboard, was not fixed in its socket.
It was not completely out of the socket, just not firmly pressed.
So I pressed it firmly and put back the cover.
After restart, the readings are back to normal.
Thanks everyone for pointing me in the right direction.

I have exactly the same problem!! Can you please help me. I tried what you said - removed back cover, pressed the connector hard, and switched on again. The problem is still there. Can you look at this picture - http://android.hdblog.it/wp-content/uploads/2012/07/Nexus-7-Teardown.jpg and tell me if the connector are the red and yellow wires on the left, on the side of the tablet closest to the camera? If so, how did you press it? Could you explain those steps once again please?? Much appreciated!

Make sure you put a piece of tape on the connector to secure both pieces together and also one on the battery to prevent it from shifting. The newer n7's had a battery that didn't fill the space for it...allowing it to shift and pull the connector free.

I had exactly the same issue. Word 4 word.
I took the back off my n7 (take the SIM holder off 1st, makes getting the back off much easier) and noticed the battery connection was loose. Unplugged fully, replugged and got my battery % back! :thumbup:

First off, for everyone that has battery-related problems, please check my thread:
http://forum.xda-developers.com/showthread.php?t=2090826
It provides "fixes" to a number of battery-related issues.
Second, the cover is really easy to get off. Just use your fingernails. Start half-way down one of the long sides (I forget which, but try both - your fingernails will easily slide into the seam). Gently snap off the cover from your starting point. Slowly work your way around. If you go slowly/carefully, it'll come off rather easily and without breaking off any tabs. It snaps back on easily as well.
In my post, I recommend that you apply a small piece of electrical tape on the battery connector, as they have shown over time to come loose for a number of N7 owners.
In all but the occasional rare case, N7's with battery-related issues are easily "fixed" and do not need to be returned for replacement. Just read my thread. It'll save you a lot of time and frustration. It'll also might save you from a needless return!
Good luck and report back.

Strange. my tablet is doing the weird battery bug. Battery stuck @ 100% for quite some time, even after a whole day of idle and @ home usage after work.
Realized it wasn't dropping.
This morning, I opened up the back and checked out the battery. It was glued down so not shifting around, but I noticed there were fingerprints on the copper material. Odd thing is I bought this tablet new. Box was sealed and everything.
So far I unplugged the battery and plugged back in. Haven't turned the device back on just yet. Might wait a couple hours and see.

Yup I stumbled upon your thread after a bit of searching. The tablet was actually rather new, just purchased a week ago. Was charging and draining fine for few days of ownership, and all of a sudden it started acting up. I realized it was too good to be true seeing 100% battery % after a whole day + gaming on it @ home.
My phone has serious temperature problems... If I surf in the internet and Facebook then my S4 is almost always at 40°C . When playing games then it can reach over 60°C (where the CPU is under the screen, measured with optical IR thermometer) It randomly starts heating up in my pocket till it is so hot that I cant hold it in there anymore.
Battery life is around 8 hours with LIGHT use!
I bought my S4 on first may and that problem appeared after summer holiday.
In November I sent it to warranty, It took them like 20 days and they did basically nothing to it. I haven't had any time to send it back there because I need my phone.
Yesterday I put it in a warm glove mining Dogecoins using AndroMine (android CPU/GPUminer) with charger connected
After 15 minutes it was at 67°C and battery was down to 30% form 97%. About 5 minutes later I heard a vibration, it had turned off and it didn't boot anymore. I was very happy, because I thought I manged to burn it down. Unfortunately it booted after cooling down . Now the battery life is even worse...
I'm thinking of putting it mining in oven... oven at 50°C I know that S4 has temperature protections but sill it might work. And the battery inside definitely doesn't like heat, so it might pop .
If I mange to burn it then I will get warranty replacement!
All crazy ideas to burn it down are welcome !!!
Sounds like a defective battery. See this thread

The thing is that my battery serial is YS1D420JS/2-B
And how can defective battery make phone become hotter?
Hi Guys just had my XL battery die.
Connected USB charger cable to PC and a part of the screen less than the size of a finger tip started to flash like an atari.
I then connected the cable to an apple plug and got the same thing.
Eventually I got access to the main charger and after 30mins of charge no luck.
THE PHONE IS DEAD!!
Yes I have insurance and still in my 1st 30days of purchase.
Please note earlier on in the day I had a hammer and the phone in the same hand, as I put them both down on a table the hammer tapped the phone ever so lightly. I am noticing a hairline crack in bottom left corner, same place the screen flashed after it died.
Funny thing is the phone was working perfectly fine until battery died.
Could be a ROM issue or the hammer caused something, OR constant use of bluetooth music today has knackered something.
Im sad to say but this phone is a *****!!
Wow. That sucks. Any luck getting it fired up yet?

Crack might have widened internally damaging the guts. Much like a glass chip can spread, a board can do the same thing. If the crack was at the bottom, you may have damaged the charging circuit.

so i have a g900f s5 and i fully charged it overnight, phone still working, then i unplugged it and went out, went to unlock it about half an hour later and the screen wouldnt turn on, yanked the battery and tried to get into download mode and nothing, no led indication or vibration, i imagine its completely dead and nothing but a board replacement will fix it, would a usb jig work to fix it, i dont have one on hand but can get one made by a friend
has anyone else had this issue or am i left with a brick
any help is appreciated

Have you got a friend or person you know who has a S5?
The first thing I'd do is see if the battery is shot, which I think is more likely the case.
A similar thing happened to my 2 year old S4 (with a battery that wasn't in the recall batch) where the phone would just charge to 100%, died after a minute or two, than takes 2 hours just to go to the charging screen saying 0% charge.

nah the batterys fine my mother has an s5, albeit stock unrooted and all that jazz and it goes fine in her phone
she actually uses my battery as a spare
EDIT: when i plug it in i can see the led flickering red very faintly
it also heats up rather fast to temps that i would consider not safe for a phone
