I've been having problems with my phone recently and I don't know what the problem is. It seems like the phone thinks there isn't any battery left and shuts off. The last time it happened, after I waited a while and turned it on, it had 87% battery left. I usually have to plug it in before I can try and turn it on again. Does anyone know what might be the problem?
Are you running a stock ROM? I suppose it could be a bad battery, depending on how old it is.

Hey there.
I have my HTC S730 for nearly 2 months now.
I don't know why but my Wings plays a strange melody and then turns off.
Even if the battery is fully loaded! After it turned off it takes a long time before i can turn it on again. I can push the start button on the top of my smartphone but nothing happens.
I don't know what it is. I Hardresetet my device 3-4 times now but it's still not working correctly.
Can you please help me?
Did anyone recieve the same "error"?
I have the same error!
But no solution.
It happens sometimes, mosty not logical... I'll wait for a few weeks, if it keeps on i'll go back for warranty!
What are you running when the reboot occurs? Never looked but is there a way to schedule it to do such a thing?
Does it display anything on screen before it happens? You might check in the power options to see if its shutting down due to some setting...
When I have some time I will dig through mine and take a look.
Off the top of my head I would surmise that its either overheating and shutting off, an installed application is causing issues and it is turning off, a setting within the phone is causing it to turn off, or something is wrong with the device.
May be caused by overheating. I have no other applikation installed on my Device since i Hardreset it. It shows up the HTC logo when it shutsdown.
I dont run any applications at all. Sometimes i listen to music with the Music Player.
When i start my phone up again (after some waiting time) it shows me that my battery power is 0. After some time of waiting it shows me that my battery is nearly fully loaded.
It only happens 1 or 2 times per day.
But please help me
It's not overheating in my case.
I saw it happen last time (5 minutes ago), just before the HTC logo is saw a little cross trough the battery indicator. I suppose the battery is not good? After reboot the indicator shows a full battery??
I would give HTC a call about those batteries. I would think that they are bad, or the phone is having issues drawing power from them and so it shuts off.
If its overheating it should be VERY warm to the touch, I have gotten mine warm but never hot after some heavy use, but I just let it cool off afterwards and it was just fine.
Usually with low battery it will flash a warning on screen and make a noise indicating low battery, but if the battery suddenly is in zero the phone could automatically shut off. Does it power off quicker than a normal shut down sequence? I would have thought that the phone would just run until it's instantly cut off by a dead battery, but if its misreading it or reads it in the danger zone it could have an auto shut down.
Had the same thing with my wings/s730.
After hard resetting it it worked fine again.
Got in last night and turned my Diamond off. Went to start it this morning and it wont do anything at all (no power or lights). Put it on charge, the bottom of the device gets hot but the actual battery is still room temperature, and it still wont switch on.
Anyone got any ideas? I'm nervous about taking it for repair as I have flashed ROM ;-(
Allready tried to remove the battery for a minute or so? Unplugged of course.
Perhaps the reset-button helps.
Running cm7 nightly 53.
I just went to reboot the phone while the hdmi was plugged in. Screen turned off, now the whole phone won't power back on. I've pulled the battery, it won't turn on at all. It's like it just died?
Does anyone have any ideas? It's only a week old so I'm guessing cm7 has bugged?
is ur battery empty? if so, and can't boot, usually remove battery, wait a few minutes, plug in everything again, but don't switch on. after that everythig is normal.
Thanks, it was the battery. I plugged the charger in and the phone turned on. I didn't even think the battery would be dead seeing as I just saw it was at 80% when I hit reboot....
Anyway, now my battery is only lasting 3-4 hours. Before I was getting 2-3 days use out of it without charging. Now I can't leave the house without my charger. Kind of defeats the purpose of it being a mobile phone.....
Sometimes I will charge it, unplug it then unlock it, and the phone will just turn off, as it turns off I can see the battery is drained in the top right corner.
I'm going to try a stock rom again.
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 :/
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.
