Wiping battery stats... - HTC Sensation

Well now that I got temp-root I decided to wipe my battery stats because I got an extended battery.
When I reboot and lose root, will it revert back to the old battery stats? And when I re-temp root, will it have the new battery stats?

From my understanding, once the battery stats are gone, they're gone. I would assume that once you wipe them you will keep with whatever you currently have. There is an app in the market that will walk you through the process and do it for you.

Should I wipe battery stats after flashing a new kernel?

Title says it all
I always do and I also make sure phone is fully charge and plugged in. Cant hurt
wouldn't hurt, also if swapping batteries as well.
Question related to this - what is everyone's battery voltages when maxed out? I heard that 4200mV is normal, but after how much I charge it and wipe stats, I never get higher than 4080mV in spare parts.

Then go to advanced>wipe battery stats and remember to charge to 100% before wiping. Then let battery completely drain until phone dies and charge back up to 100% preferably with the phone still off.
thanks guys, and sorry i got back here so late. I also use an app from the market called battery calibration. I think its better because rebooting into CWM may use some battery and you would never know
I have another question.
What exactly is the battery stats? and what does it do when I wipe it?
I've been wiping the dalvik cache and battery stats when I flash rom/kernel/etc but never really knew what they were.

Only flash battery stats when its charged to one hundred or it'll screw your battery readings. It just makes your battery meter more accurate because flashing a Rom screws with it.

After unplugging, battery stayed at 100% for hours, recently installed cyanogenmod

My buddy recently rooted my phone, I don't know much about this stuff yet. I unplugged my phone and it stayed at 100% battery for like 6 hours. My buddy says we need to wipe battery stats.
Can anybody help me with this?
Thank you
Download battery calibration from the market. Its free and the easiest way to do it.

yes wipe your battery stats
I've had problems with aosp roms doing that. The battery percentage sticks, then when you reboot, it updates.
Not sure what the cause is, but wiping battery stats didn't help.
Thanks for the replies.
I'll try all three.
How would I go about wiping battery stats? Does the phone need to be charged to 100 before doing this? Please walk me through it as if I were a 4 year old.
Recovery/ advanced/ wipe batt stats/ reboot to recovery/ system reboot.
should battery be full/plugged in to full when this happens?
If I do this, should I avoid downloading the app mentioned above?

Charger should be unpluged , battery at 50% or above is ok , download the app after you are finished.

it is best to do a full charge.
have the app on your phone, clear stats
use phone until battery is fully dead, or close to it
recharge again to 100% with out unplugging it
and you should be good.
however charging it to 100% and wiping stats will be fine.
you can do it from the battery app mentioned above, or once charged to 100%, hold power, select reboot, choose recovery, once clockwork shows up, go to advanced, wipe battery stats, "go back" reboot phone.
Thank you all very much. It is much appreciated.
I look forward to actually doing some reading in my spare time (yea right, spare time,) so that I can be more educated.

Wiping battery stats

Is wiping battery stats still the same process?
Wait for battery to completely drain
Plug in phone/boot into recovery
Wipe battery stats, then power off
And let it get a full charge?
Sent from my iPhone 4S using Siri
I almost never wipe Battery Stats, only when i'm getting horrible battery.
But if you want to do it, just wait until it's charged and wipe battery stats using "Battery Calibration" App (Faster than going into CWR). Then simply go through at least one complete battery cycle.
There's never a fixed and confirmed way about doing this.
Some said to fully drain, then wipe battery stats (no clue how do you wipe something if it's already fully drained), give it a full charge (they didn't specify if the phone has to be on/off either).
And some others said it's best to fully charge, wipe, full discharge, and then a full charge again.
Some don't even recommend it at all, saying the battery stats will "fix itself" after a couple of discharges anyway, so calibrating won't be necessary.

i tell people both ways, either charge completly full or completly drain it. then delete the batterystats.bin file and reboot. generally i use root explorer to delete it. its located in /data/system/batterystats.bin. theres many ways to do it.. in recovery, with root explorer, with a battery calibration app, or with a script in the terminal emulator.

[Q] Battery Calibration

Can you guys recommend a battery calibration app?
Currently im using ViperSaga, and yes we all know that our DS can live for a day or two depends on the usage.
Battery calibration by wiping battery stats is a myth. After 2-3 charge cycles, the indicated battery level will be as accurate as it ever will or can be.
Battery booster maybe ?
AOSP developer Dianne Hackborn has made it clear that battery calibration is a myth. It only mean deleted the battery stats. And your device does that on each reboot.
how about the wipe battery stats in the recovery? does it help the calibration of the battery?

Battery calibration does exactly that. It wipes the battery stats. And that is something your phone does automatically on each reboot.
Deleting stats is pointless indeed, but the battery calibration procedure that involves a discharge/recharge cycle, not only deletion of the stats file helps to have proper % indication that cannot happen on a Stock ROM which is the case the Google engineer is talking about. But when flashing custom is another story, then a wrong indication can appear after flashing and it has to be corrected

Though you can leave out wiping the battery, stats, the charge/discharge cycle is what helps.

Yes, including the final charging of powered off phone, that was posted in several threads lately by the same user
