Hi,
I was wondernig if any of you guys have used this app on your stock, non-rooted phones?
https://play.google.com/store/apps/...xLDMsImNvbS5uZW1hLmJhdHRlcnljYWxpYnJhdGlvbiJd
I feel like I should be getting better battery life.
One more question, if i get a replacement battery, is there a need to do anything to wipe out battery stats, or just pop in the battery and go??
Thanks again
As battery calibration apps can not work and are placebos why bother .
Battery is self calibrating .
Battery stats do not need wiping but you do no harm .They play no part whatsoever in battery drain and do not recalibrate a battery .
Better Battery Stats and Wakelocks first call for battery drain .

Hello,
I recently got the Galaxy S2 and I'm really enjoying it! the only problem i had till now is the battery drainage issue.
Because of this issue I asked what to do and someone told me to do heartagramm's tutorial of calibrating battery, the only problem is that it says in the tut i need to wipe battery stats and i can't find it in the recovery.
1. Where is it? do i need a custom recovery?
2. Do you have a different fix for the battery drainage?
(While using 3G and playing a little the battery died in 5 hours)
Battery fix is use the battery .
Battery stats via root explorer .
No custom recovery yet .
Wiping battery stats may well just be false information >> wipe stas and in a few days your battery is better or just wait a few days and your battery is better .
Battery drain = programs draining the battery ..
may help.

Hello,
I have ordered a new higher MAH battery for SGS II . I may be running stock ROM/Kernel or any of the custom AOSP ROM/Kernel.
During the kernel/ROM updates I have read that we dont usually need to clear the battery stats (since we are using the same existing battery).
However I will now be using the following battery :
http://www.amazon.com/gp/product/B0058SJ5Q4/ref=oh_o00_s01_i02_details
I need to how to properly calibrate the battery status so I can achieve full charge and maximum run time from this battery. Do I need to clear battery stats (from recovery mode) first and then insert the battery for first time usage or otherwise.
Have read a couple of posts on the subject however none provides a clear defined and fixed approach to the issue.
Any detailed guidance would be appreciated to be of benefit for the community in general.
Thanks.
=================================
Guess there are already enough methods and ways and some even debunk the myth that does the phone really needs any type of calibration/calibration apps at all or not.
Will try diving into it directly to see the effects myself if any.
You don't need to do anything other than sticking it in your phone.
When I got the 2000mah battery, I found my battery life to be equal or even slightly less than the stock one. I fully charged the battery, went to cwm and wiped battery stats, used battery completely till it died and then fully charged once again. It did seem to work as my battery life was much better.

He's right. Your battery calibrates itself with a full charging.
i read in a number of articles that you should reset/wipe your battery stats with CWM once your battery is at 100%, then switch off your phone and connect to a charger usb/plug until it will be charged to the actual 100% (usually only 1-2% at most)...

All 100% wrong .
As it only wipes the stats that show and plays no part in calibration of the battery .

thnx for the correction, what do you think about "Battery Monitor Widget" app? Does its function to calibrate actually work?
Got intrigued by the issue...
No, it doesn't. Due to hardware 'limitations', battery apps can only provide a rough guess at best of charge remaining, discharge rate, etc on SGS2.
And genuine (made by Samsung) batteries don't have to be (and cannot be) calibrated. There's a fuel gauge chip in the battery which does this automatically.
Some people having issues with the battery report charging to 100%, removing the battery for a few minutes (so the fuel gauge chip doesn't have power for that time) & putting it back in the phone fixes their issues, but even that sounds like voodoo to me.

So, some of us say that battery calibration is a must after flashing a ROM, while some never calibrate their batter, and few like to calibrate it once every 3-4 months. So it is my request to share your experience and recommendations.
This should be all you need:

Moreover, I've said it before and I'll say it again:
LITHIUM ION BATTERIES DO NOT NEED TO BE CALIBRATED. They have no "memory" effect. There's a charge circuit built into them that constantly monitors the voltage of the battery.
Attempting to calibrate a lithium ion battery will actually cause more wear in a shorter period of time than had you simply left it alone.
Sometimes when you flash ROM to ROM, old batterystats get left behind and mess up the battery. I had a glitch where it said the battery was full but the percentage was only at 92%. I'm not sure if this is a calibration glitch or just a kernel glitch, but calibrating it fixed it.

This is actually one way to calibrate battery.
And calibration means the accurate way to read batt level by ROM, which by any means, cannot harm battery itself.
Not calibrating i had the surprise to wake up with more batt than i went to sleep with. Or, as said here, you can find out that the ROM is indicating you have less batt than you actually do. I goess that is the only thing that can go wrong. Anyways, i only calibrate when flashing new ROM or restorin a backup. And i use BatteryCalibration from market.
I don't know about you guys but everytime I flash a new rom I charge to 100%,reboot in recovery and wipe everything +battery stats.From time to time I prefer to do a calibration process.It's something that i found on lg-p500.ru and works for me.If anyone is interested how I calibrate my battery,look here .
PS*offline charging is required.

+1, just search Google, there a lot of explanations on how Li-ion works, found out myself in 2009.
Just read this for crying out-loud How to Prolong Lithium-based Batteries
Edit: just in case you don't get the +1.. ''LITHIUM ION BATTERIES DO NOT NEED TO BE CALIBRATED''
It is recommended that you DONT let your battery fully discharge, ever (it shortens its life) that is one of the reasons android notifies you have a low battery on 20%.
,i think we dont need to calibrate battery,fully discharging may affect battery,thats what ive read in the internet,ahm,by the way i have battery drain now,im using lewa OS m6 + roq XII,my betterbatterystats is ok,it is sleeping,hmm do i have battery drain?,i dont want to calibrate my battery,
This is a simple way to increase the battery life in cyanogenmod... this worked for me,..
1. Goto cwm and clear the battery stats
2. Charge the phone to 100% (make sure it is 100% by checking the battery status..)
3. NOw allow it to completely discharge ... do not connect the charger until the phone is shutdown automatically...
4. Once the phone turned off due to complete draining of the battery, charge it and use it normally..,
hope it helps
i have a better idea, bring powerbank 5200ma or up, when u go out. ur device will not run out battery even on hard gaming all day long. like i did

is that a battery?? how much is the cost?
is that a battery? yes n no
yes, because it need to be charged
no, because its not a spare battery that u can plug it to ur device
it's a portable charger, in here indonesia it cost me Rp310000 or around $32

And how will wiping battery stats help??? It basically does nothing to improve battery life.

yep, maybe it doesnt help but it work for me
1st charge 100% while phone is on
2nd reboot to cwm n wipe battery stats
3rd turn the phone off then charge it to 100%, cause it will tell u that ur battery isnt full yet (charge it about 20 minutes or more)
4th turn it on while still charging
5th unplug the charger n use ur phone as usual

If it doesn't help, then how does it work???
I'm not trying to argue here, I'm just saying that wiping the stats won't help improving battery life. So if you say so, on what basis?
Anyways, cheers!
not improving battery life but, correcting current battery stats. it happen when u often switch rom n restore from cwm then u feel like ur battery drain more quickly than usual, so i tried the method i post earlier n it works

The battery stat is wiped to calibrate the battery... We may have to calibrate the battery after every rom install..

Hi everyone, I'm a newbie Android user. Currently I'm using:
DEVICE: Samsung Galaxy S3 GT-i9300
ROM: Android Revolution HD 14.0
KERNEL: Phenomenal 4.0 Medium
I've got battery problem after flashing both ROM and Kernel. I read in the both thread that they (supposed to) have excellent battery life. And there is also a thread about calibrating battery after flashing ROM/Kernel.
I lost 10% battery/hour , medium usage for Twitter(Tweakdeck) and XDA Forum ONLY...
I've done this step to calibrate:
1. Charge until 100% and 0mAh (Current Widget)
2. Wipe battery stats in Recovery Mode
Does the battery completely calibrated? Or I have to use it until 0% / 2% and charge it until 100% again? Am I missing some steps?
Thanks in advance everyone, happy Sunday and may God bless you

Above is nonsense battery re calibrates itself with use .

No need for battery calibration, the android system manages it itself while your charging your phone.

Okay then, thanks Senior! I'll be using BetterBatteryStats after fully charged to 100% :victory:
It is good practice to let the battery hit zero and recharge fully every now and then, but this applies to all Li-Ion cells. I've had batteries last me years with reasonable capacity thanks to periodical full cycles. Otherwise yeah, the actual specifics is automatic.

Total and dangerous rubbish a fully drained battery will not last as long as one that is never drained .

L-ION batteries never reach 0% or 100%. Even when your phone dies and won't come on, the battery isn't at 0%. When you leave your phone on for hours after it is full, it still isn't at 100%...
