Hi guys i got a problem with my Tab.
On Mains charge it reports 99% ( as in, fully charged ) but when I take it out it goes to an empty battery symbol, gives me low battery warning and turns off.
Any idea how I can solve this? I have no idea whats happening just started randomly after deciding to use it on a bathroom break. I've tried wiping battery stats to no avail.
I will try to reflash a rom. (i was able to do nandroid back up on the supposedely "dead" battery)
Thanks
edit: now its reporting 0% with charge symbol
ummn, what rom are u using?

I report a problem occurred with charging the battery:
never reaches the full load but stops at 75% and the LED does not become ever green to indicate a full charge.
U think that there is some software conflict?
I'll try a full recharge after an hard reset.... but first of do it:
some of you have the same problem? Is there any solution?
Thank you

It just takes "some" time to charge, but mine gets to 100%.
same problem here.after 7 hours of charging i always find it at 84%
if i make a soft reset then tha indicator shows 98% and after 2 minutes fully charged.
i think it is a rom or radio problem.
i have heard others have issues with the battery indicator too...
same problem too. After off/on or softreset reported full charged. Even with amazing FInixVGABattery soft. It will be solved out by new ROMs
I can confirm: no softwares conflict but only a Diamond's bug!
Tanks to everybody!
charged fully at 74% but once I made a soft reset, it showed 99%. So just a small reboot
I don't have any charge issues with my TD2.. Even with FInixNOverBattery app...
Battery status always reporting correctly without any errors..
Well, this problem is certainly not for everybody. Mine charges fine to 100% and then shows a green led. Maybe a faulty device?
Im another one with this problem, after an over night charge battery only shows 76% but after a soft reset it goes up to 100%, just a pain resetting it every morning guess im lucky i use memmaid to soft reset rather then have to take back cover off etc.
The same problem
Hi I have the same problem with HTC Diamond 2 - I charge it over night and in the morning is there 75%. After soft reset it is on 100%. Is there already some solution? Thank you a lot for help.
Have a look here - but no solution yet:
Battery Charge issue - bug? Reproduceable?
A couple of days ago the battery on my N1 ran out of juice. After I got back home and got a chance to plug the phone back in, I noticed the battery now doesn't charge above 54%. I've tried another battery and it's the same story, won't go past 54%. I've left the phone off and plugged in for over 12 hours and still, just 54%. I also noticed that the battery usage history does not get cleared after cycling the phone off and on. Lastly, leaving the phone on and plugged in does actually results in the battery discharging. Any help troubleshooting this would be appreciated.
Are you rooted? If so try wiping battery stats in recovery. If not then try and see if when you use it, it lasts as long as it does normally at 100% (I think it probably will) and try and run the battery to 0% and back to 100% (or what ever you can get it to) and see what happens.
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 :/
Hi guys my Xperia Z1 was charged to 100% after some use normally went down to 93% next second i pulled the phone out of the pocket it was turned off tried to turn it on got it to vibrate once but nothing showed up on display tried once again few minutzes later it booted up but just went off on bootloader. I came hame and put it on charger phone turned on showing like 50% battery drained it to zero started charging to 100 on 60-70% on charging suddenly went up to 100%
i used phone for 2 days with random reboots and after switching it on showing different percent of battery remaining, today it wont work without charger after i disconect charger phone shuts down. Could anyone tell me if this is problem with battery or its faulty motherboard maybe? thanks
ps. i need fast answer because im about to buy a battery
Tried to boot phone into safe mode and see how it reacts? Also do you use Stamina mode or any other service that changes or reads system properties?
whats the point of booting in safe mode if battery percent is going crazy even when phone is charging wile its shutdown

You have classic symptoms of a dying battery. Replace it and the problems will go away... If you did a search, you would find exactly the same symptoms described by others and the same solution. Your battery can't hold power due to a deterioration of cells.

Hello, lately I've been having some battery drainage issues with my Huawei Ascend P7.
For some reason it drains really quickly (sometimes even when the screen is turned off). Sometimes my battery jumps from 40%+ to 15% and when I plug in the charger, it jumps back to 30%+ really fast.
My phone is rooted, I'm using Doze and Greenify to save some of the battery when the screen is turned off and I also have "Screen power saving" option turned on.
I have taken some screenshots of the battery usage and one of my phone's specifications.
Does someone know what might be wrong with my phone or could there be something wrong with the battery all of a sudden?
Did you try to reinstall Android new?
Or at first a factory reset?

I flashed B852 package's recovery and boot. Then rebooted to recovery mode, wiped data and cache, then rebooted to install mode and installed B852 ROM (dload/UPDATE.APP).
The phone turns on fine, but the battery percentage just drops so quickly and once it even shut off when it was at 60%. When I tried to boot it back up it said it was outta battery.
And one time when my phone turned off and wouldn't turn back on, I plugged in the charger and it told me the phone still had 32% battery. I turned on the phone, unplugged the charger and it shut off in a minute or two. When I plugged the charger back in, it still told me I had 30%+ battery left.
I think the problems began when I flashed https://forum.xda-developers.com/as.../kernel-huawei-ascend-p6s-p7-k-tuned-t3355223 kernel. But I installed a clean B852 ROM and the problem still persists.
Thats really strange, but this kernel is not the problem.
I also have a P7-L10 B852 and using this kernel without any problem...
But right after installing this kernel I also had some strange problems...
Sometime my phone rebooted it self or if it was locked and I pressed the power button to wake it up, it just stayed black and it got really hot...
I don't know what py phone did at this moment because if you are looking at the battery info in settings, it says my phone just was turned off and even lost battery but it wasn't really off...
My solution was a clean install (erasing and flashing every single image and after that 3-button-method)
After that boot up your phone
Now shut it downs install the kernel again
Boot up
Shut downs
(Maybe flash original boot.img
Boot up
Shut down)
Install kernel again
Boot up
I'm using this kernel for more then a half year now and I don't face any problems anymore...
I think the battery itself was the problem. I removed the back cover, removed the battery and cleaned the connector pins with alcohol. When I turned the phone back on about 30 minutes later, under "Power saving" smart power plan option shows me the phone will last for 11 h 30 min at 83% (WiFi turned on), when it used to be like 2-4 hours at 90%. I'll keep monitoring for a while to see if the problem is truly gone.
Thanks for your help.
//edit1: Never mind, I tried playing with the CPU voltages and it froze, so I turned it off. Turned it back on and the problem was back. It jumped down from 80% to 14% and in a minute or two, the battery died. When I booted it into recovery, TWRP says I still have 34% left. So I rebooted into system, it showed me I did have 34% left, but it turned off. Going to try your advice now.
//edit2: Got it to work properly again. Hopefully I won't touch something that will mess it up again.
Maybe your battery itself is the problem but to proof that you will need a second P7 to change batteries of them...
But such extrem battery-problems I have never faced...
You could send it to Huawei support, maybe they will say you if your battery is damaged...
So you could buy a new one and change it
Have you tried calibrating your battery?
I don't think it's a calibration problem
But if you want you could try it...
Charge your phone to 100%
Now delete the batterystats.bin at /data/system
Reboot your phone
Use your phone normally and let it discharge right before it's shutting down it self (3% I think)
Now charge it again to 100%
While charging your phone you should not touch it or unplug the charger
Last night I went to sleep with the battery being at 90%+, woke up to my phone being dead (the alarm didn't go off).
Tried turning it on, it showed me I had 50%+ battery, but it turned off shortly after. I plugged the charger in, and it said I have 58%.
And yes, I have tried calibrating my battery. But I can try doing it again when I get back home from work tonight.
//edit: Battery calibration didn't help. I'll just have to wait until the new battery arrives. Or should I try locking the bootloader?
Why you want locking your bootloader?
Do you want to send it to the support
If you already bought a new battery, wait for it and put it in
Seems that the battery itself was the issue after all. After putting in the new battery, everything seems to be back to normal.
