I realized the mistake in my title...reporting NO charge.
I previously posted about how after clearing my battery stats it was reporting a 0% charge. I was able to leave it on the CWM screen for upwards of 5-6 hours, but the instant it loads up the OS the phone buzzes and turns off.
Now:
I got a new battery today and it appears that the battery is NOT the issue. The phone still reports a 0% charge, regardless of how long I leave it on the charger.
I'm unsure of how this could have happened, and I was curious if there was a way to completely reset the phone. IE: Every file exactly where it was when I first booted it up.
Any help would be great. I have an XPERIA Play as a back up, but I'd rather have my Thrill back.
Thanks in advance.
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, 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.
My droid turbo has started to shutdown randomly, I updated to marshmallow, had a bunch of issues that was fixed with a factory reset. I factory reset it and cleared the cache a couple times and left it in recovery till I guessed the battery was close to low, which it was like at 20% before I reset it. After I reset it I turned it off and never turned it on, just plugged in the charger. And let it charge to 100% and then let Android do its first boot on 100% so it would be calibrated or soemhing maybe. I have noticed that the phone will sometimes flash the power saver message then say shutting down in high percentages and display 0% need to charge screen, and after holding the power button sometimes it will come back on and boot up at like 70 or 80 %. It really happens alot below 20%, like alot. I've asociatied 20% with 0% on my phone because of it. Is there any recommendations on what to do, I plan to replace the battery myself.
So my turbo just turned 2. For the past 6 months or so been having some weird issue. I was on RR Remix for a while, then went to CM14 by BBH27 for a while, and then back to RR, and now on ComputerFreak Stock. I don't have any issue with charging the phone. Quick charge works just fine.
I have had issues where the battery will just be dead even if it was at like 50% and confirmed charging.
I thought maybe it was my stupid charger (I have another that I have yet to test) but then last night, after charging my phone before I went to bed i unplugged it. I woke up around 6:45 to find my phone once again dead. It looks like around 2 am the battery just fell. Dead. Just gone. I go and hit the power button and i got 1%. The battery graph looks as if i turned the phone off. For the most part my battery last all day 12+ hours with some good usage too.
I'm getting ready to flash back to stock now that full stock MM is out now to flash and see if that makes any difference.
For what it's worth, my Turbo would just straight up shutdown when I was on RR. And not go through the shutdown process, just crash to a powered off state. It would happen if the battery was full, low, or anywhere in between. I don't know if that's the issue you were experiencing, but I suppose it's possible.
My daughters is having the same issue.
Anyone have a solution?
I've tried clearing caches, battery recalibration, etc.
Going to see about doing a fully clean install tomorrow if she is okay with it.
When this happens and the phone just shuts down, does the battery percentage immediately jump back up when you plug in a charging cable? I was having that problem when using wireless charging a lot. It turned out be a battery calibration issue. You can re-calibrate by holding the power button and KEEP holding it when the "Power Off" dialog pops up. The phone will eventually reboot itself then leave it overnight on the factory turbo-charger.
One warning - Since the marshmallow update, performing this procedure seems to wipeout your BT connections.
