I noticed today that my phone has maintained a 100% charge, even hours after being unplugged. I tried rebooting, but that didn't fix it. I tried to boot into recovery (I have TWRP) to see if I can wipe battery stats, but once I selected recovery, an empty battery icon appeared and the phone shut off. I tried to boot up normally again, and the phone crashed outright during the boot animation and shut off.
After a minute the phone started up by itself, and went through optimizing apps (I plugged it into a charger out of curiosity). Now that the phone was able to boot, the battery is at 5% and finally charging again.
Has anyone else had this happen with their N6, or have any idea as to what might cause this? For reference, I'm running the latest stock image (LMY48I), just unlocked, rooted, and with custom recovery.
Only thing I have seen is apparently wireless charging screws it up. Go into bootloader>bootloader logs and reboot from there. May reset it.

Hello,
Yesterday my Incredible S was booted into android, when I found it didn't charge anymore. The LED worked (showing red), and also it said "Charging", however the percentage only stayed the same, or went down. Since it reached 0% I can't get it to boot anymore. When I plug in the charger, the red LED blinks shortly and then boots into recovery (Clockworkmod 6), where it appears to be stable as long as I keep the charger in, and when I remove the plug it stays on for a minute or 5.
I can't boot into android or even into fastboot, but it will only (automatically) boot into recovery. I've tried different chargers and outlets, and i've also tried cleaning the cache and factory reset.
My current rom was android 4.4.4 (http://forum.xda-developers.com/showthread.php?t=2519414) though I don't think the rom is the problem.
Has anyone ever experienced something similar? Is my battery faulty and can I just replace it, or is this probably not it? Any ideas?
Thank you in advance.
PS: my recovery seemed to have changed it's menu since I experienced my problem: Some options seem to have changed, including that I can not select the "Wipe battery stats" anywhere anymore.

Let me guess is your recovery is TWRP 2.6V?
If it is it is a known bug :fingers-crossed:
I recommend using CWM 5.0.xxV
My phone is giving some really weird issues. all of it has started since I have upgraded to lollipop. First, the phone would hang mid way and then suddenly won't turn on. If would work only after I plugged it in to a charger and leave it for sometime. The phone would then start charging from 0%
So I went to recovery and did a factory reset. Clear cache, dalvik and data. Re-imported everything. Recharged the phone to 100%. And voila it worked on the same charge for 3 days. So far so good.
After the next recharge, I was showing one of my colleagues the custom recovery and the fastboot mode. When I turned the phone back on, it again hanged for a moment.
But this time around, instead of loosing all the charge, I lost only a part of it. Any ideas guys?
So I tried to flash a rom today. Well, I tried to update it. I know I shouldn't have, but I aborted the process because it got hung up on the same thing for 10 minutes. Surprise, everything's screwed up. But don't worry, I fixed it. I literally re-constructed the system image through adb (the system folder was just deleted for some reason) and got the phone to boot again. But then the network wasn't working anymore, so I flashed the rom again and nope still not working. So then I flashed it AGAIN and my phone was low on battery and I was in class and it flashed fine, but then it shut off during boot. And now it's constantly turning on and booting over and over, and the battery is super low, and I can't access recovery. Or the bootloader. No combinations work, nothing. So here I am, completely at my own fault and stupidity. Ideas?
Here's the symptoms:
I plugged it in after class, 0% charge. Oops. Not supposed to do that.
Waited. Waited. Got to bootloader, tried to enter recovery. Not enough battery, waited.
Got to recovery, tried to boot normally, and now it gets the the "powered by android" screen for a couple of seconds, shuts down, and restarts the process.
My theory:
The phone is so low on battery it can't continue booting, so it shuts off. It uses what little battery it has to put the screen brightness on full and boot, repeat.
PDATE:
It's been a good hour or so, and the phone still shows 0% charge and wont boot. It's really hot.
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.
Mine is Marshmallow, Rooted Stock ROM with TWRP.
From couple of days suddenly phone is shutting down automatically after using some time like there is no charging, but even there is charging.
When going to TWRP, battery percentage showing the actual percentage.
But if restarts the phone, it is starting and getting shut down like no charging.
If I was on any Custom Recovery, I would have tried Reset Battery Stats. But I am on stock ROM.
Please help me.
