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?

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.

Yes.
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 ?

[PROBLEM] Battery gives wrong info. Even battery calliberation Doesnt work

Hello...
I am now on stock XXJPM.
I was on Kyrollis and have changed a lot of roms.
Ok... so my battery is having an error.
Once i plug in my charger within 2 minutes it says 100%. And once plugged out it says 5%. WTF is it ?
I had flashed XXJPM twice and removed both my sd and sim card.
idk whats the problem.
Even tried battery calliberation when it was 100% and in a couple of seconds it went back to 5%.
Plz help me guys.

May be you discharged battery to much and damage a safety chipset on battery.
It may happened too with to high battery temperature.
Anyway how long phone may work on that 5%? Did you make data wipe?
And you aren't able to check rom/phone with other battery?

ok try this...
1) Discharge battery completely...try switching on the phone even with 0 battery...it may just switch on and then switch off automatically, do this until it becomes completely dead..
2) Start Charging with phone switched off...let it charge for like 2 hours i say...even if it shows full battery in that charging animation.
3) Switch ON...use battery calibration, without 100% also do it...
4) Restart Phone and let it charge till 100%...
5) Should work then...if still then flash, DDJG6 eclair and update via kies...then take it to samsung center

[Q] battery calibrate after flashing rom ?

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 %.

[Q] I have replaced my charger , battery is damaged !! HELP

I have lost my original charger ,so I have order another one from here :
http://www.ebay.com/itm/380751287837?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649
After this , my battery performance has decreased nearly to the half.
Here is what I get every day , ( in the pictures )
What I have noticed for more than a week is this : every time my battery reaches 37% , it decreases like I am using it heavily although I am not using the phone AT ALL !!
Is the charger I bought fake ?
Is there anyway I can fix the problem ?
Any advice ??
Would you recommend any ebay seller to buy new orignal battery.
Thanks.

To me it just looks like the battery is not calibrated. Try to calibrate the battery and see if it works.

my battery too. when it reaches 37% it decrease more quick than normal. Use caribrate no work but dont worst like your battery. I use original charger

Thanks for the reply.
1. How do I calibrate my battery ?
2. Does the screen time seems normal to you ??

Also i recommend "Juice Defender" app. It does great help saving battery. Hope that helps a bit.

I tried to calibrate my phone and my phone reached about 45% then shut down like the picture.
any advice ?

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..

Dont worry
Our note maybe sometime not show right battery percent so it just normal
If you want reboot with 100% then you should plug in and reboot
