[Q] HELP unable to charge my phone above 75%!

did anyone ever experience that thing?
i'm charging my phone it reaches 75% and then stops... sometimes even battery gets lower...
even if i charge the battery completly on another phone and switch between the batteries i still get that the battery is at 75%! (even when i charge the phone when its turned off!)
i tried Darky Resurrection 10.2 and the problem still exists...
tried to wipe battery stats with (battery calibration app and from CWM) no success...
anyone got an idea???
(clearly its not battery or charger since i got 2 galaxy and only one has a problem...)

Buy titanium backup and freeze "Samsung Account" and "software updater" these are the two main things that eat battery. Also let your battery run flat, then once it has died (try switching on the confirm it's dead) then plug in charger whilst phone is off and allow to charge fully, once it says its full, unplug (don't switch on yet) plug back in to confirm its full, if so..enter recovery, wipe battery stats and reboot. This will need to be repeated 2-3 times

Phone turns of at 5-9% how to wipe without recovery

Hi Guys,
I have a rooted Xperia V with the original 1.140 -Version.
Since a month I do have the problem, that the phone turns off, at 5-8%.
My battery monitor widget, which I have since the first day of the Phone, shows me: 0% at 3010mV
But it turns of at 3400-3500mV.
I tried about 10times in a row to fully unload the phone and then a full recharge. But it didnt helped.
I deleted the batterystatsbin. Didnt helped.
I remember from my old Defy with CWM, that there was a point in recoverymode which allowed me to wipe my battery.
I would like to do that, but I dont get into recovery mode.
Volume + and power didnt helped, volume - puts me in safe mode, like windows safemode.
Can somebody help me to get clean batterystats again?
plz? :fingers-crossed:

Wiping batterystats has nothing to do with calibrating battery, it just wipes the stats shown under Settings - Power - Battery.
You should search for how to calibrate battery, there are several options available here on XDA.

I hope you did not simply mean by calibrate battery:
Deleting batterstats.bin.
In fact I searched XDA and the german forum android-hilfe.de for some days and didnt found an answer.

My best advice is to let phone discharge so it dies by itself, then fully charge it to 100% without any powering on under charge process. When charged to 100 - turn on phone and let it charge additional 1 hour so it can add back the lost procentage values that was lost during boot up..

I followed your instructions. After that I let the phone discharge so it dies by itself. Same problem... 7% at 3208mV and it dies.
Furthermore theres a new "problem". As it charges while it turned off, the battery-icon wasnt fully loaded, it has a space between fully loaded and the acutal status. The green LED was on, as it does by 90%. After half an hour nothing changes, I turned on the phone, charger still plugged in, and it showed 99%. With this status it loaded 10-20min till it has 100%.
After some minutes, it might be 15, I removed the charger and used the phone normaly.
So it was an uninterrupting loading time of nearly 4h to 100%. But normaly it takes only 2:30h from 0%-100% with the 1760mAh Battery and the original 1500mAh-Charger.
Now the funny fact:
Normaly I have till now 70% Battery left. I do have at the moment 86%.
I dont get it...

That sounds like indicator problem. What ROM you use? Try to wipe cache and dalvik cache.

Maybe some hardware problem, I do not get any idea what cause it...

Thanks for the reply Shut_ down.
Everything starts happening when I removed my sim and put in the another Android mobile and then again in my Mobile.
I recd one GPRS setting message from Vodafone but I ignored the same.
Is the cause root.
Now whenever I Power off my phone it starts automatically within 15-20 seconds.

Hmmm, maybe your micro usb connector on phone is faulty. When you connect cable with PC it will act like that...

What is the solution for it..... Just now I have changed my battery.
Battery size was increased / Swollen type.

[Q] Battery / % / Calibration Issue

Hello, i've been using my HTC One M7 for over 9 months now, and i'm facing some major issue with the battery, it's very awful ! i'll post some screenshots at the end, i've made a lot of researches to try fixing this battery issue:
TUTO 1 : when the phone shuts down, plug it to the original charger and wait for 2 min, then press and hold the power key + vol+ and vol- for 5 minutes and release then when the screen is on [Not Working]
TUTO 2 : download an app from the market for battery calibration [Not Working]
TUTO 3 : for root users, wait until your phone is dead, and plug it into the charger for about 3 hours for full charge without turning it on, then just power it up and let it rest for 30 minutes [Not Working]
TUTO 4 : flash a ROM [Untested]
what happens, is that my phone is draining battery normally but when it reaches 40% (sometimes before) and i'm using any application, it'll shut down and state that the battery is empty, if i waited the 40% to pass and then launch an app the battery will jump from 40% to 28% then to 12% then 1% and shuts down.. some people say it's because of the power saver.. some say it's from a third party app.
before it happens only when my phone reaches 9% then jumps from 9 to 3 then shuts down.. i'm lost, any one ? please

Got also the 9% failure. Tried to calibrate my battery but it didnt work. Since I flashed a new ROM it disappeared.

Calibration of the battery is a myth that was put to rest long ago by many. Even Google's own developers said it was a myth.

this one is after flashing the ViperOne Rom and the ElementalX kernel.. i'm still having this issue :/

Anyone ?

I don't remember who posted it but this worked for me.
Charge your phone to full while booted up / unplug phone
then reboot recovery / plug phone in and wait till it says 100% in recovery
power off / unplug phone / plug in the phone and wait till the battery says 100%. It seems the 3 different modes / booted up / recovery / and off all have different ideas of when the battery is actually full. The whole process took about 15 min.

I let mine charge overnight it said full, but in recovery the phone was only at 87%. after about 10/20 min. charging it was full. Then with the phone off it again showed less than full like 93% .. 10/15 more min. and it said full

what recovery do you have ?

sorry to bring this one up again but I am also having this exact problem, also if I turn the phone back on it will load up but as soon as it finishes booting it thinks the battery is at 0% so it turns off, after doing the calibration method once, it finishes booting up and shows how much battery there really is which was around 12% when this last happened last night.
I am actually running completely stock Android 4.4 not rooted or any mods.

My Battery lasted 7H 19M today, phone showed it was 55% remaining and turned off.. as you can see in the attachment of the battery history

Had a similar bug long ago. Factory reset fixed it (I think). I deleted everything on the phone so that I HAD to RUU a ROM on the phone. After that my battery worked normally. Maybe a bug, a virus, anything but I formatted it and now it works like a charm.

Have you tried a hardware battery recalibration?
The battery calibration starts with the phone completely off. The steps are as follows: Charge the device for at least 10 minutes using the original charging cable in a wall outlet. With the device powered off while still plugged into the wall outlet, press and hold the volume up, volume down and power button for two full minutes. Use three fingers to hold these buttons and do not let go at any time. They will be held in at the same time for this to work. After two minutes, you can let go. At this point, the device should boot up and battery/charging logic will be re-calibrated.

I also charge the phone to 100% then boot to recovery and let it go to 100%
then shut down the phone and charge it to 100% ...all three areas show different battery levels. when all 3 are full your good to go

[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.
