So I am just curious. Why would I need to reset battery stats? Whats a good battery life? I know where to go to reset, but I don't see why I would need to. Any thoughts on this?
If you start getting bad battery life or a full wype rom can goof bat stats up sometimes. If you getting bad battery life for more then 5 days then you should do it. Becuase rom flashing and cause battery to go out of wack for a couple of charges. Also charger 100% with phone off, then wipe, then 100% while off... you also might want to search a littler bit better not to be rude but this link was 5 thread down in general...

Hi,
Just a quick one and any responses from personal experiance would be great.
Has anyone used an app to re-calibrate the battery? If so did it help or did it seem to make the battery life worse?
I had a major drain on my battery so did a complete reinstall of tweaky ROM and the drain has stopped. Just wondering if I should bother to recalibrate
Thanks

Calibration did not help me, I have the same stamina... JVH + Criskelo v56 + CF-Root 3.2
from those many many times i have tried to do calibration in all possible ways that has being suggested even waiting a few days for the cycle to end...
my conclusion its bull**** it depends on the rom or apps that are running ....
the only thing it does it shows u 100% when u finish charging in case u dont see it already.
Does it work or does waiting two weeks for battery to settle down work .

My findings are similar to JJE. After flashing a ROM, it will take 4-5 charge cycles (just charging every night, nothing special....may run down to 0% after first charge) before I see a stable, decent battery life.

Ditto, I try not to judge a ROMs battery appetite until about a week, espescially if I was to lazy to flash at 100%.. But I think that is what is meant by battery calibration..
Ok thanks guys, think I'll wipe battery stats next time I flash a new ROM 100% battery

hey guys,
i got a little problem with my sgs: it shows me that the battery charges itselfs if i don't use my phone for a little bit (for example: i play half an our lane splitter and battery goes to 23% then i leave it for an our in standby and when i come back it shows 28!)
I hope the screenshot might can help you.
P.S.: Sorry for my bad english
...
Did you also try battery calibration app from market?I don't know if it does anything else than clearing battery stats, but I think it's worth trying...root is needed though.

I have tried it with the app and with cwm. Both didnt help.
I think both do the same thing.
Sorry for bad english.

You can try to do a wipe battery stats in recovery after you have done a full charage.
..
Maybe just your battery is already death, try another battery if you have a possibility.
..
I have this issue too. I think it estimates battery and when it is left to idle it gets more accurate. I notice if I continue using it it still dies but idling saved battery..... could show battery percentage according to usage ? ( although I'm guessing here)

So my phone died earlier and I charged it up to 100%. Note that I was also running ICS4Bionic (latest build). So I switched back to stock by toggling Safe Mode and it tells me that my battery charge is at 40%.. (???)
I rebooted just to make sure and the battery level IS ACTUALLY AT 40%. Weirdest thing I've ever seen. Do I need to do something with battery stats or what? It doesn't even make sense.

I get excessive battery drain when I go back to nonsafe mode. Any suggestions?

Thanks, it worked.
Would an app like Battery Calibration work as well? Just wanted to know for future reference.

I essentially had the same problem. 100% to 40% when switching back to nonsafe.
It's probably not actually draining. Maybe you just need to reset the battery stats like it was suggested. It did work for me.
Yup same thing as fare as I know

Already did the first time.
Thanks a bunch.

Mine is a different problem. I know what your talking about because that happened to me also. I'm talking about my battery level draining really fast while in using it. I've reset the battery stats already and recollaberated it. My cell standby is really draining the battery very fast.

Get a free battery calibrate app from market. Wiping battery stats do no really do anything reported by Google.
I was messing with my phone (rooting, testing out roms, etc.) and I decided I just wanted plain old stock. So I put it back to stock (official 2.3.5 gingerbread) and rooted it. Then I decided to calibrate the battery by using the Battery Calibration app in the Play Store.
Now my battery drains about 15% every hours in standby mode. Do I need to wait more time for the Battery calibration to take effect?
The calibration doesn't work on stock it only work on custom ROMs... kies calibrates the phone and reset the batterystats.bin so there should be something else killing your battery especially 3g...disable what ever you are not using rotation/data sync/bt/ ect.

It's still draining that fast on airplane mode.

"Calibrating" the battery is huge myth. It does absolutely nothing.
batterystats.bin is used to display what has been using your battery in about phone/battery use. That's it. Has nothing to do with calculating the remaining battery, or does not improve or decrease battery life in any way.
Furthermore it is reset EVERY TIME YOU CHARGE TO 100%

That's what I've read but it must do something, because since I ran that app and 'recalibrated' the battery, the battery dies in about 7 hours on stand-by. It would last me all day before I ran that app.
I did find one thing that was using battery on standby...my Beautiful Widgets Live Wallpaper. I set the wallpaper turned off the screen and after three hours I checked the battery use. I found that 'Display' was using the most at 50%. And during that time, it drained about 45%. I'll keep testing.
Oh yeah forgot live wall paper kill around 20% never use it so case close....

It looks like that's the culprit. I must've put on the live wallpaper sometime after 'recalibrating' and didn't remember. I'll let you know if I have anymore problems.

Hi guys i have a galaxy s phone and it's working really great, but now a days it shows me some weird battery problems...
ProblemNo:1.Some times my battery shows like 45% or like that and it goes up to 46 or 47% after a few minutes during discharge
2.Some times when i have about 55% then if i remove my battery and put it back and when i reboot it shows only 5%, this problem is very rare but it's occurred more than 2 times
3. when i am charging my phone it's reach up to 99% then it drop down to 98% then 99,100
These are my problems,i am using MIUI 2.4.20 ROM
what causing these problems is it my battery faulty or do i have a hardware problem
or is it the ROM
please any one help me.....
Have you tried wiping the battery stats in cwm?
Or, trying a battery calibration app from the play store? For example, Battery Calibration.
Problem number 1 occurred to me a few times it isn't a serious issue.
Problem 3 you need to wipe battery stats and calibrate your battery (play store has apps for that)

My guess is that using multiple batteries is playing havoc with your battery stats, but what the solution is I have no idea to be honest

i am using only one battery not multiple batteries
i don't think that battery stats file has anything to do with this problem, it's something else...
my worst fear is that is it my phone's any hardware part is faulty.....!!
Or guys is this problem occur if my battery is faulty....?
help me to sort out the problem............
I have this issue also.. I checked and my battery is on good health, really annoying but nothing I can't live with

I fond that if its at say 50% and I reboot and it drops to say 5% it takes ages to discharge that 5% so I guess it has the same charge just reading it wrong, if I leave it for a while without using it it will go back up

I was thinking of a back up phone. I guess this is off the list.
