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 ?

[SOLVED] Critical BATTERY drain issue!!!

Can someone help me troubleshoot my battery issue??
I tried calibrating.. but it doesn't seem to work.. no matter how many cycles are done.. it still stays the same..
My battery drains out and my phone switches off within a few minutes and sometimes even in a few seconds when the Data Connection is ON.
But without Data Connection ON.. the battery seems to drain comparatively lesser and lasts for about 5 hours after very less usage..
And, I have observed that with the data connection ON, and keeping the phone on stand-by (i.e. Without using the phone and keeping screen off), the battery seems to stay at 100% for over 2 hours. :O ..and the very instant, I start using the phone, it switches off saying that the battery is low... :/
I have tried different kernels and different governors too.. didn't help.. :/
I would really appreciate it if someone helps me troubleshoot this issue.
Thank You!!
God Bless!

I'd suggest you read it again.. :/
If it's 'cus of my battery.. then there wouldn't be an "EXTRA" battery drain with the data ON and the battery would drain out even without the Data Connection ON..
Hope You Got Me.
Thanks For The Reply Though.

Umm.. ah.. I dunno.. I still think it is a BAD Case of Battery Mis-calibration. :/

I have the same problem i charge the fone till 100% i.e. full charge and unplug then start data connection then it switch off within five minutes and u want to know a strange thing when i talk with a full charged battery it gives me around 6 hours of battery backup.
i m going to give my fone at service within 3 days, i think it is some kind of hardware problem because the battery giving me around 6 hours of talktime so it is not due to battery
and yes i tested old kernels formate system and flash stock rom with stock kernel but nothing helped me..

i hav tested al typ of old , new custom or stock rom & kernels..!! nothing clicked..

Try to charge when the phone is off to 100 %. Boot up and wait 'til you get the 'remove charger' message. Now calibrate your battery and unplug. Hope it works!

hey man.. thanx fr ur concern.. but it s not dat we missed sumthing.. we r havin dis prob for last month.. we hav trd every solution & tricks & tweaks.. but all in vain..!!

....and ANYONE who can help us have a "normal" battery life again. Please GUIDE us!! :'(

yep i trd this like 100 times as i thought cwm is not capable to do this..
i m 1000% sure.. u & i having d exact same prob..

My battery lasts around 12-14 hrs.. on my UNINOR simcard..
and whn i use my AIRTEL simcard it easily pulls over a day...
and yup i always have my data connection on and fair amount of phone usage...
so i guess it's something to do with the network of carriers as it looks like our android uses hell lot of battery just to get the network signal..
and yeah Uninor signal sucks at my workplace...
so the point is for few of us it could also be a bad reception area case..
p:s: a2sd too sucks more than reasonable amount of battery, try uninstall it and get ur apps on ur phone memory and see the difference..

battery drain while wifi data connection is ON
Has anyone notice battery drain while wifi data connection is ON. I have Kyrilos 7.1 rom with G3mod 1.7 performance. When I connect to my wifi network battery is draining in the way that you can count backwards

But really in my opinion its a battery DEFECT for sure. While data connection is on cell radio is used more transmitting data eating more power so your phone drains more quickly.
I think try a new battery. Or simply go to Service Centre to have a checkup.
But really this should be battery defect. How old is your battery? Did you bump charged?
See when I used Data Connctn my phone lasted 12 to 13 hours on continue use of FB, Nimbuzz, Gtalk, Youtube, maps, gmail auto sync. when I switched off gtalk maps etc I got 16 hours apprx and when no data connection was there at all I still remember I got 4.5 days battery life. From this it is clear Data connctn uses a lot of battery and so does the Internet Related media and Services.
My IDEA-
I suggest you first completely discharge the battery, Discharge it completely keep on switching on after it turns off again switch on and continue that when discharged completely.charge 100% in Power Off without any cut offs. Calibrate, wipe battery stats and then again COMPLETELY DISCHARGE. Now Again charge 100% in Power Off Mode if it works then enjoy if not google for some time more, search the thread and then if nothing comes up go for a new battery.

Check out the battery/lags tackling thread link in my signature!! hope that helps

After days of experimentation and frustration,
I, now, have a good battery backup of around 35Hours without data connection ON and average usage including around 150 Texts and 15 Minutes of call.. and a about 5 hours of doing different stuffs on the phone..
Though I'm yet to test it with data connection ON.
Here's what I did to get the fairly "good" battery backup without data connection ON.
I charged my phone to 100%. And started using it 'til it switched itself off at around 88%. Then I waited for about 10 minutes before switching it on again.. I repeated the same process 'till the battery drained to 0%...

I had the same battery problem. So i decided to change it with my friend. I used his battery for about 15 minutes and everything was working perfectly. In other hand he was not able to use mine more than 2 minutes. So it is definitely not the problem in phone itself but in battery.

battery weird issue

plz i need your help.
i download my battery til it was 100% then i restart the battery shows 98% i repeat this few time always the same
i download battery calibration and when it was on 100% i calibrate the battery but still same after 1 reboot 98%

it's not weird...it usual..because they need a lot battery to start up, and it's normal to have 98%..mine too also like that..it's depend on ur background apps too..

First try calibrating your battery by fully draining it to zero...take it out ...then put it back it and turn it on till the phone does not turn on at all...then charge it back fully see if it charges up to 100%. If not then your battery is failing and u need a new battery

Incorrect battery status!!

Hello im using validus Oreo ROM
Almost the ROM was good
But one problem
While I switch off my mobile and charge it
After the two hour I look the phone it show me 20% battery
But I use the mobile for an hour the battery was still at 20%
I think it has incorrect battery status bug
Even I restart the mobile again again and again it show only 20%
Any alternative method?? To know my correct battery status
