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

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%

So yesterday I calibrated my battery and was suprised it actually worked. But today I flashed a new rom (for like the 6th time this week, I think I have a problem) Should I calibrate again?

I /think/ it's only when you flash a rom without a fully charged battery.
Sent from my SAMSUNG-SGH-I897 using XDA App
Well if you have tons of time I don't see why not. Most of the time, I feel that it is not necessary to calibrate the battery. I only do it when there is a severe battery drain.

+1 to this. Please ensure u flash a ROM after u charge the battery to 100%.

Charge the phone till 100% while it is turned on, disconnect the cable.
Turn it off and charge it till it's 100%, disconnect cable.
Turn it on and off, charge till it's 100% and disconnect the cable.
Now, delete battery stats using CWM or run the following command using ADB or Terminal Emulator:
Code:
su
rm /data/system/batterystats.bin
Sorry but what is cwm?

Do i need to do a battery calibration when switching between the extended battery and the regular? Depending on my work day i take a different batter with me but the extended seems to be dropping as fast at the standard one. I am running Blurry 1.3 ROM.
IMO its just a placebo effect

I had never run one before but when I stitched to blurry 1.3 I was losing 10% battery life every thirty minutes while not in use!! I was told to run the calibration on it and boy did it help, now I drop ten or so every hour/hour and a half with heavy usage, and only a percent or two when not in use.
Sent from my DROID BIONIC using XDA App
Absolutely. Placebo? The battery stats are for the stock battery. You put a bigger battery in, and you don't think you need to tell your system?
Don't calibrate and enjoy the same battery life you got on the regular battery.

Anybody that has used this app.. I charged to 100%, clicked on Calibrate, then unplugged. But at about 50% battery an app caused my phone to freeze and couldn't even power+up+down reset. I pulled the battery. Do I have to start over with the calibration? There isn't any indicator on the Battery Calibrator app.
I don't think so
Just read that all these programs do is delete a batterystat file somewhere and Android will rewrite it at times. Thx.

You should only do it when fully charged. Charge your phone to 100% then leave it plugged in for another 20 minutes, till it's at around 4200mV. Delete batterystats.bin and it will be replaced during reboot.
Edit: the issue is that your battery will drain in cwm even while plugged in. Battery Calibrate does the same thing only without having to go into cwm.

"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

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%

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.
