Would it work to just copy the battery stats file to another rom so u don't have to re calibrate everytime u install one or would that be a bad idea

You don't need to calibrate, just charge it full. Battery stats are automatically wiped when you unplug with a full charge.

Well the new 3500 milliamp battery I got says to fully discharge and charge 4-5 times to get the most out of ur battery. Or is that just for when u first get it

Just when you first get it. Its a "break in" for batteries.

Although I believe that its good to do a full discharge and charge every so often.

Alright that's what I thought. Although while discharging my phone froze up and rebooted so I think ill have to recalibrate again lol

It shouldn't affect battery. I've tested it myself, battery life before and after calibration is no different. This calibration myth was debunked by a google framework engineer.
Sent from my XT860 using xda premium
ya I read a short thing on that. Kinda odd though. Seems like sometimes u could get a worse battery life some days compared to others. But it also seems like a good idea since u don't have to calibrate every time u do something.

The calibration has nothing to do with the battery life, it just gives a more "exact" reading of the battery level.. I miscalibrated my battery once, and it was at 1% for about 3 hours, then finally died..

Ya that happened to me once. Now I just make a point of being able to fully charge anytime I flash a rom.

I have now been convinced that there is no reason to calibrate your battery at anytime. Google engineer pretty much put it to rest and since then I have flashed repeatedly and all that changes is the ROM , sometimes battery is bad and other times its great. CM9 is best so far. Until we get new kernals our battery won't ever be great.

Ya reading through the comments it seems batterystats.bin has nothing to do with the displayed battery level, but rather just what is using the battery. The displayed battery level comes from kernel level

Same, although not for 3 hours but 15min heavy load (720p mkv). Which normally kills 10% battery.
After calibrate it never happened again and died right after 1%
I some up this morning and saw my battery was at 88%, it has bin on charge all night how can I fox this so it charges to 100%?

"some up"? Ok... go to CWM->Advanced->Wipe Battery Stats ... if doesn't work, do a full wipe or reflash ROM, you are using...
Woke* auto correct lol, and o do this after every ROM flash and this wouldn't affect that anyway, its not done it before, only to 98% or something but I read that it does this it will reach 100% the stop charging to preserve the battery, but dropping to 88% is a bit extreme I think I'm losing like an hour of battery life

This is a calibration problem caused exactly by you wiping your battery stats, you need to leave them alone and after each flash do a full empty to full charge cycle so the stats can provide proper calibration statistics, I have never wiped battery stats in 2 years of owning my phone
I always do this after a wipe, wait till fully charged>wipe stats>discharge fully>recharge fully
Sent from my GT-I9000 running remICS-UX using XDA premium
Ok, I know the point you are making but I personally think it does more harm than good.... Does it drop straight down the moment you remove the charger?
I don't know if it might be a battery problem, or if the CM9 Nightly build I'm currently on holds a charge really well, but sometimes I charge my phone up to 100%, then after about 30 minutes of continuous, non-stop usage, the battery is still at 99%.
Is this odd behaviour or is it normal?

No it only charges to 88% unless I remove charger then plug it back in again then it will charge to 100%, I think its because the phone charges to 100% then drains then charges, but I think its failing to start charging once it drops to a certain limit (say 10%) so normally it would charge to 100% drop to 90% then charge to 100% so it doesn't damage the battery, but as I said I think its failing to start charging again so it just keeps falling... I need a fix for this? And yes it is a cm9 base

I've always been wondering: is it possible to "damage" the battery or lose some of it's juice by doing wipe battery stats to many times?

Probably a battery calibration problem... Wait until ALL the battery has drained, when it reaches about 2-3% then screenshot. The battery's indicator in the ace is quite buggy. When it says 74% it probably means 90%

Also you can try juicie defender, search it on the playstore.
Just fully charge your phone. Not when it hits 100% in 30 minutes you gonna pull the charger.

If your ROM drains too much battery, try another, such as droidace, or maxiAce I'm using now, both of them are good at battery as well as the UI.

This is common in Cyanogenmod roms. So, Firstly, change your Battery Status Style to Icon.
The instant when battery says 100% or charged, actually it's not fully charged. You'll still see the spark in battery's icon. Keep it charging for extra 30-45 mins. Also, when the battery is fully charged, you'll not see that spark in battery's icon while the charger is plugged in.

Wipe baterry status should help, go to CWM recovery / adwanced / choose it: wipe baterry status and restart.
Last night I charged my phone and unplugged it around 6:30 am, but used it for maybe 10-15 minutes total for some calling and light apps like iGag, but as you can see, Android OS drained almost 30% of the battery while the phone was idling.
What exactly is Android OS, because I can't find the exact apps which drained the battery so badly. Any apps or advices for detecting the troubled apps or an advice? Thanks guys. :good:
Try battery stats plus from Google Play.run it for while, it will calculate which apps are draining your battery most.

This 2% per 5 mins is when the phone is in standby mode ?
then there is some crap that is eating all your battery.
have a look at the battery usage and see what is using the battery most, in my case it's exchange service -- i cant do anything there because i use email app to get my office emails.
please reply with the app that is using most battery.

I don't think it'll matter.
Looks like your battery is dead. This phone is the most power-effective phone I owned since Motorola Defy+, it can hold any abuse and still has juice at the end of the day.

And then you've either installed some app that keeps your phone constantly awake, or killed the battery immediately by discharging it to 0. That's the only 2 explanations.
Right now I'm 17h on battery at 50% remaining, and screen as the top discharge reason with 32%. My father, who doesn't use the same phone extensively, routinely charges it once in 2 days. You should have screwed up something really bad to cause this phone not to hold charge.

Could be killed battery. This app won't do anything bad, I believe.
Might also be something reception-related, but I'm not sure if the reception is good/bad or if your carrier does/doesn't support fast dormancy and to what degree does it affect the phone.
