Battery and charging - Huawei Ascend P7

Hi, I have experienced a strange problem with my phone. When I got the previous version of android b832 I have noticed that the battery drain was very fast. Then I upgraded til b852 the battery holds longer but sometimes I have a problem with charging the phone.
A few times i it was charging almost the whole night and when I checked the battery it was the same level 12% as it was a day before. Sometimes it even discharges. Sometimes take the charger out of the socket helps but not always. The charger is very warm but the phone does not charge. The biggest problem is when the battery level is below 30%. I have also noticed that the phone gets a big warmer than with the previous versions of android. I wonder if its the device or the software. I have a month of the guarantee left. So if I want to do something with that it is the last call.

Did you try a factory reset after the upgrade to B852?
If not you could try
But backup your data before

Maybe you should give this app a try.

Battery Drain
I have kikat on P7, just suddenly after recharging using Xperia M2 charger, battery is discharging very rapidly. Have no problem since 1 year. I have rooted it and also hard reset. Still no effect. Any idea? If flashing ROM can help?

If you have unlocked bootloader you could try a clean install

no i do not have it. and i am a bit to scared to do it myself. what do you mean by clean install?
i think that a problem with the battery occured after upgrading the phone to b839. then i upgraded it to b852. and the problem with charging ocured. i am on b839 now i wonder if i can use b800 backage to roll back. perhaps that would help...

You could try to download the full package of 852 and put it on SD card or internal storage in a folder called "dload" and boot up your phone by holding power vol + and vol -
But safe your data before it's like a factory reset with fresh install

but i thinkbthr problmr eith charging began when i updated ro b852. before that in b839 the battery drain was quick but it charged fine. now when i downgraded to b839. the problme with charging happends again. but it is not so frequent yet. someone told me that perhaps it is motherboard to blame. perhaps it is a shortcut. the phone did not have contact with water but they found rust i the headphones socket. but as i remember the problem bwgan with updating to b852. perhaps a coincidence.

[Q] My Z1 has a strange battery problem

I have just bought an unlocked Xperia Z1 second-hand.
Seller said it sometimes goes out.
Model is C6903.
When it's on charger, phone doesn't go out. Strange thing is that it charges normally for about 6-7% regardless of the actual battery level, and after these few percentages it jumps to 100% even though some seconds ago it could have been at 17%.
This is strange in itself already, but wait.
When I get the phone off the charger, it acts normally. Battery starts discharging, the amount depends on the use.
After 6 minutes of 1080p Youtube, the battery is down to 92% from 100%. Well, it's not a good performance, but still it works.
And then, all of a sudden, it goes after around 8-10 minutes of battery time, no matter if I do something or not.
After going out, it is stuck in a bootloop, because it cannot sense enough charge in the battery to start. If i put it on charger, the bootloop remains. I have to do a hard reset using the red button next to the sim slot. And then, i put it on charger, offline charging starts, and it says around 55% battery. I start android (still on charger), and now it says 3% when booted into the system. After a restart (still on charger) it goes up to about 60%.
I don't really know what the problem can be. I have tested the issue several times, with sim in, without sim, with Sd in, without sd as well.
I have reflashed the original rom, tried 3 different versions (4.2.2 , 4.3 and 4.4.4), no use.
Tried different, custom kernels too, no use. Tried custom ROMs, no use.
Tried calibrating the battery with a program (deleted the batterystats.bin), no use.
Tried charging continously for 8+ hours, still the same happens.
I have tried different battery programs, they all said battery has good health (also Sony built-in test).
Battery programs said that while charging, battery is at 4.23V which is okay. When it's off charger, it slowly goes down from 4.2V to around 3.8V, and sometimes even below (the lowest I could see was 3.1V).
Battery specs: 3.8V and 3000mAh if it helps.
I think my battery could be defective, but it can also be the mobo. What should I do?
Have you tried a complete factory reset and or reflash of firmware?

Yes I have tried factory reset, and as I said above I have reflashed the firmware several times

I would have said to you to calibrate battery but you already did it...
So it must not be a software problem...Probably a hardware problem(I don't think the mo/bo has a problem but who knows ).Try sending it to service and probably they will replace your battery.
I don't think there is a major problem with your device

Phone randomly shuts down and loses all battery

I own a Samsung Galaxy S Advance I9070 and i've got a problem with it. for the past 3 weeks, it randomly shuts down, and drains all it's battery, and won't start until i plug the charger in it, after that, the battery goes up instantly to somewhere between 70%-100%, and then i can open it without any problems, then. it works for a couple of mins and it happens again. I even did a factory reset but the problem persists .

HI , well that is weird have you tried anything yet like
factory reset , clean data cache in recovery ? try that and see if the problem still exists also
specify what rom you are using and did it happened after installation of some apk or .zip file ?

I cleared the data cache and i factory reset it in recovery mode now. i will try to boot it up and then i'll see if this still happens
Edit: it still happens , i'm guessing it's kind of a battery problem since it works perfectly fine when it's plugged in, but when i plug it out, it works for a minute then it dies. i'll try to let the battery completly discharge then recharge it and see how it does.

[Q] Battery problems

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.

Honor 9 lite

I bought an Honor 9 lite it is 2 weeks old, been working fine, night before last it showed a notification message 'Battery temp. too low, functionality of phone may be affected'.
Since then it has rebooted, reset and all totally wiped back to factory reset, however now the phone when I plug it in to charge is charging but only goes as high as 2%.
Any ideas please, 2% charge is limited to what I can do within the phone and wont stay on long enough when connected to laptop through USB.
Saw someone mention calibrating the battery? would this fix it?
can anyone help please?

You can try recalibrating the battery.
But since you just bought the device taking it to the service center would most probably give you a free repair if it's a battery problem.
Recalibrating battery
How would I recalibrate the battery please? A step by step simple guide for a novice many thanks

just back to earlier versions of EMUI
if you have a PC connect to HISUITE and select update then choose earlier version
you can't back 2 versions at same time you will back one version every time
the best version that will works for you is EMUI 9.1.0.133
that is my experience with my huawei phone after planing to send it to china for repair
it's a software issue not battery or hardware problem
Even though a bit late, updating for anyone who still faces this issue.
I also had this problem from Oct-20 and followed the steps to revert to older EMUI version for the phone to charge till 100%.
I did revert back to 10.0.0.195 and it started working for me normally. Immediately I had disabled all Auto-updates features.
Somehow, a system parameter update happened and again my phone went back to stop charging at 60%.
Now I believe this System Parameters update to be the root cause of the issue. I am using 10.1 version now without any problem since I haven't updated the system parameters.
