So the question is inspired by the numerous references to the 'battery reconditioning' procedure. Is it necessary/desirable to reset the battery stats after inserting a spare one? The follow up question: are the battery stats remembered for individual batteries, and if so - how many battery stats it can remember?
From Team Whisky's site:
1. Charge phone completely, leave plugged into power
2. Boot into recovery
3. Wipe battery stats
4. Reboot to normal
5. Remove power cable
6. Drain that sucker all the way
7. Recharge fully
8. Rejoice!"
My problem is I do not see an option to wipe battery stats when I boot into recovery, be it clockwork or stock recovery, what gives?
Clockword Recovery > Advanced > Wipe battery stats (I am pretty sure)

In Clockwork, Install Packages>> Advanced >> Wipe Battery Stats.
To the OP: I don't think it remembers multipie batteries. I wouldn't reset each time you switch out. Assuming your batteries are the same capacity, the meter should be close enough.

Thanks, the problem is that one battery is (obviously) Samsung OEM, while others are cheap replicas (with the same nominal capacity). I noticed they last much less, which is expected, but I wonder if part of the problem is incorrect battery stats... It is too bad if multiple stats cannot be remembered...
I'll try to "recondition" the replica battery and see if
A) that improves its life
B) it negatively affects OEM battery life
I'll post the results here. If B) really happens, then a mod is necessary that preserves battery stats...

I do feel a little sheepish asking this question but how does one properly reset battery stats. I just updated to Obsidian v2, best Rom out there right now, insane battery life, but I am using old battery stats. Not sure how to reset the stats to get even more life. A link or how to would be great, thanks.

reboot into clockwork recovery, choose advanced, chose wipe battery stats, reboot.
Great thanks.
Charge it all the way to 100%
Reboot into CWM recovery -> Advanced -> Wipe Battery Stats while still plugged into a power source
Reboot
Unplug the device, and drain it all the way till it shutsdown
Charge to 100% while the device is shutdown
Can someone please tell me how I do this on a rooted 2.1? It's driving me mad trying to google it and I need to reset the battery stats to improve the battery life.
install xrecovery (dev thread) goto "advanced" > "wipe battery stats".
Edit: i just used this myself, but how would this "improve" the lifecycle of a battery?
Do SE battery's have a chip on them that counts the used hours/days, or is it just the android fw that keeps track?
(I have 2 fake battery's also (ebay), so i never run out of juice in case of the chip.. i bet these fake's dont have a chip.. kinda like fake PSP batterys (special pandora's excluded))
it won't improve the battery life.
however, you can maintain your battery life and align the battery stats to actual battery level by draining it until the phone cannot power back on. plug it in, wipe stats, power off, let it charge fully, then leave it on the charger for about an hour afterwards before powering it back on.

EDIT: Oops... wrong thread
anyone know how to wipe batt stats if phone is not rooted?
is it even possible?
So what exactly is the correct way to recondition your battery after installing a new rom? I have been following the Bionix version of recondition below
1. Charge phone completely, leave plugged into power
2. Boot into recovery
3. Wipe battery stats
4. Reboot
5. Remove power cable
6. Drain that sucker all the way
7. Recharge fully
But i see there is some discussion on the proper way, and this one ruining your battery life. What is the actual correct way then?
That's the method I used a few weeks ago. Can't say there was any noticeable improvement, but I've never read that it was the wrong way....

So in all essence... Dont do it! Haha then what is the point of wipe battery stats? Should i still at least wipe it at 100 percent after its charged, and then just use it normally.

The "point" of it is just to get the software to know the upper and lower limits of the battery to it can more accurately determine its current level. It learns the battery level and becomes more accurate over time, but many here flash new ROMs too frequently for it to get the chance. Just use your phone and don't worry about the battery, you will be fine. Leave it on all the time, even at night. Charge it when ever you are idle for any length of time and over night. You can not over charge it and it does not have a memory, but you can certainly shorten its lifespan by deep cycling it. If you think the battery meter is really way off what it should be then clear it first thing in the morning after it has been charging. Also, don't be surprised if you rarely or never see 100%. This is the normal way the charger keeps heat buildup from killing the battery. 97% to 99% after a charge is fine.
Thanks T313C0mun1s7, that's the most sensible advice about the battery I've read in awhile.
I need help resolving funky battery charge status with my Vibrant.
I flashed to ICS Euphoria RC2.1, everything is working well but noticed that when I plug the phone to charge the battery, I get wrong charging statuses. The LockScreen displays 'Charged' status. However, the StatusBar displays charge status at 95% and charging and the battery never charges past 95%. Is anyone having this issue also? Is there a fix for it?
It sounds like you might need to recalibrate your battery by wiping the battery stats using cwm or battery calibration from the market the second one requires that you be rooted here are the directions
1. Charge the device to full battery; let it keep charging until the battery says it is fully charged. Do not just wait until the light is green, it isn't always fully charged, causing a lot of inaccuracies. (You can check by going to: Settings » About device » Status » Battery Level = Full.) 2. Boot to recovery mode and delete the battery stats NOTE: To have the most accurate of battery stats, reboot the device immediately after wiping the battery stats and wait for CyanogenMod to boot completely to the desktop. Once your entire boot is done and you have full access to the device, go ahead and pull the charger and continue with this troubleshooter.
3. Do not charge the device until after draining the battery completely, resulting in it automatically shutting off. 4. Recharge the device completely and then use as you normally would.
Though the directions are for a different rom the steps should be the same
I'll try that, thanks.

I think that I need to wipe my battery stats, but without CWM installed, I don't know how. Here's why I need (I think) to wipe the stats:
1. I broke the screen of my XT912 Maxx.
2. Instead of replacing the screen, I bought an XT912 non-Maxx and then swapped the back, chassis and battery per this YouTube video.
3. Since completing the swap, my Razr reports crazy battery levels. For example, it will go from 30% to 0% to 40% in the space of a few minutes.
I theorize that the phone is "confused" by having the 3,300 mAh EB40 battery that comes on a Maxx instead of the 1,780 mAh EB20 battery that comes on a non-Maxx. Anyway, I am hoping that wiping the battery stats may fix the problem. It sure can't hurt. However, I don't know how to wipe the stats without CWM install and I can't find a guide for installing it on the latest/newest stock OS (4.0.4? -- can't verify at the moment).
When I boot into the recover that is on the phone, there's no option (that I see) to wipe battery stats.
Any suggestions?
Wiping battery stats , AFAIK, means deleting /data/system/batterystats.bin
So you can manually do this with a root explorer, or use an app called battery calibrator.
If that doesn't work, maybe you can try using the phone til the battery drains completely and turn off. The try truning on again til it doesn't. And then charge the battery for a long time ~8 hours with phone off.
