Hey Guys,
I'm having quite a peculiar problem with my phone lately. After being fully charged, when the battery is depleted to around 30% the phone randomly shuts off. This happens either while in the middle of using it or right after the lockscreen. When I plug in my phone it boots, and the battery is completely depleted. After trying multiple roms including Paranoid Android, CM 10.2, Stock Sense 5, Google Edition 4.3 and Slimbean the problem still persists. I honestly have no clue what is happening. My guess is either the phone isn't reading battery percentage properly or something is wacked with the power supply. Any suggestions and insight would be greatly appreciated.

Hi,
My battery life/indicator has been behaving very strangely since yesterday, so I'm wondering if the battery is dying. I know about battery calibration, and attempting it hasn't solved anything. I haven't flashed any firmware recently.
When I plug in the charger while on, it almost immediately tells me it's 100% charged, but the number displayed will still be something low, like 50ish. When I unplug it, the number stays. It drops extremely quickly, to around 1-2%, then 0% and turns itself off. After turning it on again, it may rise to 10%, but drop again to 0% shortly thereafter. After a couple of times of turning it back on, it will refuse to turn on. Charging only seems to work when phone is off, but even then the charge won't last much more than a couple of hours of idling - no calls, no web, nothing.
I've tried charging to full while phone is off (drained), and removing battery stats via cwm before booting up. Doesn't help.
Is my battery faulty? It's a very sudden problem, and my battery has been lasting me for days before this happened
So, I got a new battery. The problem persists. I've tried a factory reset/wiping battery stats, but it's still that way. Could this be a hardware problem somehow?
Any advice is greatly appreciated!!
Which fimware are you on? In your case I'd go back to a stock firmware from samfirmware.com and test once again. If the problem persits, you likely have a hardware issue and I'd have it swapped for a new phone whilst within warranty.

I'm using tweaky rom, JVS. I'm not too sure what the local firmware is (Singapore), the one I had before I switched to custom was 2.1, and I don't feel too safe flashing bootloaders when the phone is prone to turning off...

yeah, you are absolutely right. Have you tried betterbatterystats? ( http://forum.xda-developers.com/showthread.php?t=1179809 ) It will show you wakelocks when your phone should be idling.
Did it help ?
Mate, out of curiosity I was wondering if your issue got resolved.
Also, you should check what is draining off your battery.
I tried reading elsewhere and found "Battery Monitor Widget" could be useful for you to identify this.
Nope, still same problem. It's not a wakelock issue, because the battery dies /so/ fast. I can literally charge it to 100%, unplug the charger, and in 30 seconds it says 0% and turns itself off. The phone itself isn't running hot or anything, and seems to be just idling. [Edit: To clarify, it also charges to 100% in about 10 minutes or so. I'm guessing that for some reason the phone thinks the battery is 'full' and stops charging, leading to the quick drop. I've no idea what could cause this though]
I'm hoping that maybe it's a software issue now since the new battery isn't working either (the battery is probably a fake since i got it for cheap, but even then it should last at least a few hours before draining), and that the phone is confused with battery voltage levels or something when I put the new one in.
Anyway, I flashed JVU stock, didn't even root, and will be charging the new battery overnight while phone is off. It says 100%, but gonna leave it on charger anyway. Hopefully if I wake up tomorrow it'll be working :/
If that doesn't work, will be flashing DXJV9 (My original firmware was dxj4), and hope that it's the official one here. Then bring it to a service center and act dumb and hope they can fix it i guess...
Service center replaced motherboard. There goes a hundred bucks :/
I rooted my phone last week thanks to the xda forum
[ROM]-Unoffical AOKP
[Kernel]-No change.
phone worked great, awesome battery life, was on the phone for 4 hours and still i had 40% left, that to while using skype on wifi. Normally the phone used to die within the first 2-3 hours.
I was checking on the various kernels, just coz i wanted to get the ATT world phone image out of my phone! so i used icyglitchv14, well it worked.
But for some reason the phone's battery seemed to drain faster when the phones idle. The phone was back to its crappy battery life.
Yesterday, i flashed the unofficial AOKP ROM build 25 (thanks) the battery life improved drastically, though i have no clue as to why!
Problem now? Battery won't charge, rebooted, turned phone off, but battery just wouldn't charge.
Solution: Remove the battery, hold on to the power button for 5s, replace the battery and turn on the phone. It started charging.
I don't know if its a bug, or if its got to do with the icyglitch power states ( i used conservative), but hope someone checks this out.
i am 100% baffled that this just worked for me, but thanks so much for posting this
Thanks marcknight.
Noticed it around 15% and started to panic.
Turned to my trusty XDA hoping for a solution before it died completely.
One of those strange instances of: Don't ask HOW or WHY, just know that it works.
this worked for me!
this worked for me!
I was also using aokp build 40 ics. and the power mode I believe that I set it on was conservative, I guess i shouldn't use that mode anymore! My power button also doesn't work very well so i was basically mashing all of the buttons while the battery was out of the phone and also while the phone was plugged in, then i inserted the battery and it just started booting with the att screen.
Not charging
That happens to me today. Because I read this earlier I did the same and Voila!!
Thanks!!!
Mine stopped charging too.. and its stock
I am running stock ATT firmware and the battery will charge outside the phone but in the phone it shows charging but gos dead. I have tried the 2 amp power charger for my nexus 7 and that won't even charge it. Good thing I got a cheap external charger a while back.
Anyone know what could be causing this?
a guess: removing the battery, then holding the power key for a few seconds causes the max8998 power management chip to reset, probably by discharging a capacitor or equivalent.
liberate your captivate on xda
Having the same thing happen to me right now. I using the Captivating ROM, just tried your solution, will see how goes. Thanks.
Hi all,
I have to turn to asking this question because i tried searching for all help to no avail. My friend's galaxy tab have been having a serious battery indication issues. We tried a few roms, the Stock ROM, Overcome 9.1, AOKP Milestone 6 and MIUI.
What happens is that the battery charges full but when plugged out immediately falls to 75%. Upon using to near 40% it shuts off.
When we reboot it, the battery indication is different always.
We tried clearing the battery data, clearing battery voltage, switching off the tab and charging it, press and hold power and the screen all to no avail.
Anyone encounter similar issues?
Hi Guys
I am running Cyanogenmod 12.1 nightly, and have the following issues:
1) If the phone is off, and I put it on charge it boots into a sort of "battery charging mode" which shows a big battery with the capacity charged inside it. The problem is that even when the picture of the battery goes away, the screen backlight remains on throughout, which obviously simultaneously uses power and consequently takes longer to charge. Is there any way of getting the screen to switch off?
2) If I use the phone until the battery is dead, I cannot obviously reboot. Then I plug it in, and it boots into the mode above. Whilst plugged in and the battery is dead, it will not boot up (on the factory rom even if the phone is dead, as soon as you plug it in you can boot it and it will chrage whilst the ROM is booted up). I then have to wait until it has charged a bit in the mode described in (1), unplug it, then boot it up, and let it charge whilst booted after I manage to get it booted. This whole process entails at least 10 minutes of downtime
Are there any ways around this? It is properly irritating
Bump
Does anyone else have the same issue? Is it normal?
confirming
can confirm it's normal. Having this on PAC. Just keep an eye on your battery and don't let it die I guess?
What is PAC?
Are there any roms as stable and sleek as CM, with good battery life and consistent development, which doesn't have this problem?

PAC is another ROM. Unfortunately Paranoid Android is the only ROM along with Omnirom not based on CM sources, so no, there aren't any AOSP roms without this issue I'm afraid.
OK cool thanks. Guess I should move back to the oem rom
Hey all,
Let me start this thread by saying I have replaced the battery in my Nexus 6, and I'm also running Pure Nexus and Franco Kernel.
So I've been abroad the past month, and noticed that my phone will just die at times. Sometimes it will turn on again, sometimes it won't turn on until it's been plugged in (can't get into recovery mode or bootloader, it's just a black screen). So I've noticed when I lose signal, it'll frequently turn off, usually in this scenario the phone will turn back on again. This is a pain but I can deal with this. But sometimes when I'm using the device, it shuts down and won't turn on without being plugged in. It can be on any % of battery, if I plug in and pull out again, it will remain on the same % of battery as before it shut down, and will run for hours on end.
I bought the replacement battery off of eBay, claimed to be a manufacturer replacement but of course, no way to verify this, could possibly just have Motorola printed on the battery. However I've experienced the phone turning off when no signal even when using the original battery.
Any suggestions to solve either of these issues, ideas on what you think the issues are caused by or suggestions for how to diagnose are greatly appreciated!
Cheers,
Sam
It won't be any direct help for you, but I have noticed after getting 7.0.0 that my Nexus will re-boot randomly once every week or two. Battery level can be at 100%, and I believe it has even happened while setting on the Qi charger. Not sure if it is 7.0.0, or some app that does not play well with it.
