Hi, yesterday my phone run out of power so i put it to wall charger. it was still running but battery showed 5%.
Then i made it off and i went sleep and kept it plugged. Today i cant access my phone, i managed to get to recovery and changed rom to cm7.1.2 ( i thought it has some issue with ics rom) and my phone doesn't start up at all, sometimes it turns on when i keep it plugged it tries to charge battery shows 5% and turns off again. i tried to boot it up without battery inside but with no luck.
This can be battery based problem or something with phone ?
(Haven't found any solution on the web yet)
RE: problem solved, battery just started loading

Hello All,
I am facing a strange issue but something that has become a nuisance and made my Note unusable.
I was happily running Ultimate JB 4.1.2 v5.1 when I downloaded something related to green them of sysui( name not entirely sure)
from the OTA update section in ultimate ROM and installed throught CWM.
After the installation, suddenly I found that my battery is not charging.
I connected through wall charger and even tried chargin through USB from my laptop. Nothing worked.
I flashed again with V5.1, then V5 and even Rocket Rom V12 several times while clearing the battery stat as well.
Once it worked when the battery started showing as getting charged,
but then USB mass storage was not being shown when I connected the phone through USB to my laptop.
So I flashed again. Finally after several attempts of flashing different Roms (All JB ultimate V5 and 5.1 and RRV12),
my battery started to get charged.
And now, yet again, for no change made to my Note, I have this problem appearing all of a sudden.
Battery not charging and now it has discharged completely. It either goes into boot loop or doesnt start at all.
USB storage hasnt worked since the problem started with the battery charging.
I am not sure what the problem is, but very unlikely problem with ROM.
I flashed the ROMs properly, doing factory reset, clearing Dalvik case, formatting /system, /preload etc.
There is no problem with the charger cable, for the battery gets heated even when my phone is off, but I see no battery charging signs.
any help please? Anyone?
I guess the problem is not related to the rom..its just a coincidence
Try with another charger and battery of ur friends
Sent from my GT-N7000 using xda premium
also try an official Samsung rom ICS or GB
I was facing the similar issue, but in my case when the battery was 10% i flashed cm9.1 stable rom without gapps or anything, and then the phone booted up and the battery was charging, (very slowly at first and then normal).
you could also try replacing the battery. I had a similar problem a few months back and when i checked the battery, it was already bloated so i repalced it. After replacing the battery, it went back to normal
Hey guys,
I'm facing some weird battery behavior ever since I flashed my phone with unofficial roms.
I'm currently using a Cyanogenmod 12.1 Unofficial build. I'm going explain the problem as detailed as possible.
Everything works fine, except after a boot, the phone ALWAYS shuts down in 2 to 3 minutes while a SIM card is present.
If a SIM card is not present, the phone shuts down anytime between 5 minutes to 1 hour.
The reason? The battery reading jumps from an accurate value to 0% and the phone shuts down.
ALSO, When I connect a charger, the phone shows "Charging" but no battery is detected (Charging 0% AC), so when I remove the charger, the phone immediately shuts down due to 0% battery.
Lets call this Mode 1
---
Well, now I tried something. I connected the charger, and then pulled out the battery while it was still connected.
The phone went off.
Now on a restart, the phone stays at the bootloader screen for 1.5 to 2 minutes (Samsung GS3 I9305)
Now after the phone boots up, everything looks normal, but now, the battery stays at 99% all the time. No matter how much I use or try to charge it, 99% always.
This is Mode 2
In short,
Mode 1: 5 seconds at bootloader, Accurate battery reading, Sudden 0%, phone shutdown
Mode 2: 2 minutes at bootloader, Inaccurate 99% battery reading, never shuts down.
Now I can switch between Mode 1 and Mode 2 by connecting a charger and pulling out the battery while its still connected. I've done this atleast 4 times and it always worked. Weird.
What is going on really? Any ideas on how to fix this?
P.S.
I've tried:
Flashing Samsung S3 i9305 stock 4.4.4
Flashing Cyanogenmod 10.1 (Official)
Flashing Cyanogenmod 11 ( Latest Nightly build)
Same problem everywhere.
Also tried Battery Calibration apps
I don't have a backup of the original stock rom as it was already broken in the first place.
Hello, XDA developers. As you may see, this is my first post, but I would like you to tell me what happened with my cellphone.
Something weird happened with my S Advance after I rooted it and installed CyanogenMod 11. I was playing on it, as I changed MinFree settings and overclocked the processor and wanted to check how the performance increased. Suddenly, the phone abruptly shut off without showing the traditional dialogue box that should appear.
When I took the phone to connect it to my battery pack I waited for like 5 minutes and the battery symbol never appeared; after that I tried to turn it on but it didn't work either. As soon as I arrived home, I connected a proper charger to the S Advance and, still, it didn't respond at all.
About one hour later I took the phone and now, when I tried to turn it on (in normal and recovery mode), it would only vibrate for a few seconds, as if it was actually turning on - with the difference that nothing was happening. The only boot mode that I could enter to was the download mode.
Saddened because I thought it was bricked, I came to my room and plugged it to my computer. The screen instantly showed the battery charging sign, and when I turned it on everything was normal. I used my wall charger to try, and it keeps working fine.
I understand that when a phone battery reaches 0%, and you try plug it to a charger you need to wait like 10 minutes to actually turn it on. But in this case was an hour! And when I finally turned the phone the battery was at 0%.
Could you tell me what happened (for potential future ocasions)?
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.
For quite some time I already have the problem that the phone almost always shuts down once i plug in the charger.
It reboots to the bootloader, recovery selection and then briefly shows 65% battery and then the actual battery state.
I'm currently on AOSP 6, however this problem was already present with older versions. I also tried using different basebands without success.
This issue has been becoming quite annoying as I always have to manually restart the phone again to actually boot up instead of showing the charging animation when turned off. I hope you guys can help me with this.
