Just a question if you guys encounter this. Im using audax v13..stock kernel.
When i charge my phone to 100 then pull out the cable then the battery all of a sudden reads 88%.
So weird. Is there a fix for this? I didnt observe the phone cause it was just given to me and i root and installed audax asap.
Download battery calibration (root) from the play store.
If your phone is fully charged open battery calibration (root) and calibrate, this way the app will delete all old battery stats and make a new file.
I had the same problem but now it's fixed.

When you recalibrate your battery, it takes a few life cycles for the battery to stabilize and for Android to get an accurate reading. First life cycle is alway short. Of course, don't play with ROMs so much it may damage your phones read only memory.
I will post my battery life soon, I'm still waiting for the battery to deplete, I haven't recharged my phone in 4 days now after I calibrated my battery.

Wow 4days is huge,iam getting hardly 1day battery after calibrating yesterday....
Actually i removed my phone before getting the 100% notification....
So should i wait for battery to improve???
By the way,when did you calibrate???
Should i calibrate again????
If this wont work i will try terminal emulator method...
So in this method do we need to charge 100% or discharge completely??
Some precautions or just write those commands at any point of charge???
Iam wondering how to thank from the xda app
Thnx to both of u

Same problem here.
Battery drained from 100% to 60% in 3 hours, then to 15% after 5 hours. phone super hot! Widget showed temp 42°C !
Not even used the phone for more than 15 min! REALLY!
Then calibrated before 3 days, now a max of 1 day battery backup only.
Plz help.
And 1 life cycle means I must let the phone charge 100% then let it discharge till it's switched off.
And I should repeat the cycle.correct me if I am wrong.
And I have the habit of not charging to 100% in a single charge session, 2-3 breaks, should I change it?
clarkkov said:
If your phone is hot without you using it, something is running in the background, that shouldn't. Which ROM are you using and which tweaks/fixes have you applied?
One battery life cycle means battery drain from 100% (fully charged) to 1% (fully discharged). Your phone does not have to turn itself off, but make sure it is at 1% when you begin to charge it again. This is important only for a few cycles after calibration, afterwards you are free to charge it as you wish, but while calibrating it's highly recommended that you don't interrupt the charging process (4Hrs).

I am using rooted jpd from samfirmware, no fixes except sdcard speed fix, previously it used to give a good battery backup.
And apps do run in background.
Should I set autokill level to high in task killer?
And I will take care of charging.
Thanks for support.
on DDJP2.. getting a horrible backup since i have updated thru KIES. generally on jg6 used to get almost 1.5 days which has come down to 12-16 hours now. trying to calibrate my battery with app 'battery calibration'.. calibrated once.. but still no change. read somewhr that we get the same backup for first few times even after calibrating.. but to get sure i am writing down my process.. plz chk if m doing right or not ..
1. plug in phone with charger
2. wait till 100%.
3. press battery calibration or delete batterystat.bin with the help of root explorer.
4. unplug charger and use it till it discharges completely.
5. charge again to 100%.
plzzzz chk and tell.
plzz someone reply.

You need to be aware that wireless services are draining the battery the most. If you are not using 3G - switch it off, same with BT and WIFI. Widgets that update frequently also drain the battery fast, background data, auto sync services/features are battery killers, too.

Thanx for the reply.. i have calibrated once more.. but already showing 80% after hardly 2 hrs.. no clue whats going on... ppl with JP2 shud come up with thr battery backup to get confirmed.
and last thing am waiting for is that someone said .. battery life is worse for first few cycles after the calibration... thats the last hope... :'(

Thx for the aswer, i thought that all the background data are drain lot of battery. I'll try to calibrate and switch off all the thing i can and see if my battery lives more time
Hey there,
scince I use BatteryLeftWidget, I can see that my battery voltage only reches 4171mVolt.
So, batterystat.bin delete doesnt help, so anyone an idea where to put the 4200mV ?
This happens when battery level is below like 30% on my HTC Evo. I am using a customized ROM (Supersense). Whenever the battery reaches 30% remaining, it doesn't drop. However, if I use the phone for a while and restart it, the battery shows only 10%. Clearly, some of the battery management program does not work properly. Is it a bug related to battery itself (hardware) or ROM (software)? Anyway to fix this?
You could try charging your phone up fully then go into recovery and delete the battery stats(Under Advanced in CWM), unplug your phone and use it until it discharges fully and shuts off. Finally, recharge the phone fully again once it has died. I believe this will calibrate the software that monitors your battery or something like that. You can find more specific instructions on the net if you want. Some people like to bump charge and everything else to try to get it perfect but I never found the need to go to that extreme.

Download "battery left" from the market and it will recalibrate your battery. Also yes, I would reset battery stats as well but battery left will actually recalibrate it. Battery stats is how long the phone has been on, what's using the most battery, etc. Correct me if I'm wrong.
Just boot into recovery and wipe battery stats.
I had this problem once.
All I did was download "Battery Left" as VICODAN said and I flashed this zip that I got from somewhere on this site but I forget where. I had to change the updater-script and the binary but either way it works on our Shift. Charge to 100% and flash this, then with Battery Left install use the phone till it dies and after that, you should be golden.

U can try the app battery calibration also in the market. If you're rooted.
*Since we're talking about batteries.
I wish our phones would beep or set off an alarm when charged to 100%.
I was keeping battery calibration just for that, it has that option but only worked maybe 1 out of 20 times the alarm went off.

Love the app, so when i got to sleep or I am going to calibrate, I just open the calibration app throw it on charge, it beeps I hit calibrate unplug and done. That way I don't have to open the app when It's 100% or with early morning fuzzy eyes and fingers that don't work right

I flashed a ROM and had a doubt , do I need to batter calibrate the phone using an app from the play store or does the battery stats refresh to normal after charging to 100% ?

Hi,
No need to delete the "batterystats.bin" file, as you said it's reseted at 100 %.
Hi,
I've recently replaced my battery and now it is not charging fully to 100% but only to 85%. Sometimes it displays it is fully charged but after a minute the percentage dropped to 85%. I've already tried multiple chargers with no result. The only thing that works is bump charging. It looks like the battery is just working fine but the displayed percentage is not right. Is there a way to 'reset' this statistic? Removing the battery.bin didn't do anything for me.
Is there a way to check if the battery is really fully charged despite the wrong displayed percentage?

To fix what you are doing you have to be rooted.
1. Root your n4
2. Download root browser from playstore
3. Go to data/system directory and delete batterystats.bin
4. Accept superuser access
5. Reboot and let the battery drain till 0%
Anyway, I don't know if it will be a battery calibration issue, because if u had to replace your previous battery maybe your phone doesn't manage battery well and destroy them... Try, report, and we will make conclusions

I just deleted it, it's worth a try!
The weird thing is bump charging will result in a 100% charge and the battery seems to work normally (20hours of battery time with normal use).

It will be a battery calibration issue since that file only stores the statistics of apps. It gets deleted upon reboot. So this won't affect the measurements in any way.

Connect the charger to the Nexus 4, then insert the plug.
Press the power button and hold it until the device turns on. Immediately after this, press and hold the Volume Down key, not releasing the power button. Appears on the screen Start, circled arrow.
Pressing the Volume Down key, select Power off and activate it by pressing the power button.
When the phone is turned off, unplug the charger and plug it in again. then turn on the phone.
Both solutions didn't work for me. Is there a way to confirm that even if Android displays a value of 85% the battery is fully charged? Because I don't care that much wrong percentage is displayed, I just wanna know for sure the battery is ok.

you should try reflashing your rom
Wipe cache, dalvik cache and battery stats in recovery then fix permissions and reboot.

Or restart your phone and battery stats will reset.
Hi,
Battery drain due to "Phone" app in battery status.
It's draining battery. Some times it takes more than 50% of battery, but becomes normal after reboot.
Attaching the screenshot. I've done nothing, just unplugged from charging.
How to solve?
I'm using stock KK, with Lean Kernel.
Even on full stock rom and kernel. This problem was there.
Anyone help?
No one?
Screenshot looks normal to me phone used 15% of 4%
Suggest you get a battery calibration app from play store and reset your battery stats as it might clear any errors .
I've done that, But it comes up mostly when I receive or make a call. After that unless I restart the phone, Phone.apk keeps on draining battery.
Do you have Phone.apk for note 3? I've ready somewhere that If you replace the default apk file, it solves the problem.
Thanks
