Hi,
WIPING BATTERY STATS MYTH
In terms of the new battery,just cycle(Charge fully/discharge fully) it as normal.

RECALIBRATION:
A recalibration is mostly needed, when dealing with different kernels (ROOT!). Most custom recovery images provide the option "battery stats wipe" under the menue "Wipe".
Here is how ya do it!
1. Enter Recovery Mode
3. Enter "Advanced"-Menue
4. do "Wipe Battery stats"
5. reboot
Calibrate the battery by completely draining it until the phone completely shuts itself off.
Turn the phone on again and let it shut itself off one more time.
Then charge your phone while it is off for over 8 hours.
This will fully charge the battery so that when the Android is turned on, it now sees the battery as full.
It is recommended to repeat this process at least one more time.
You should see a significant increase in your battery’s charge life.
Calibration of a battery can be done at any point and a maintenance calibration is recommended every month.
Thanks for this useful guide
Hi,
Your posted information doesn't sound true for me. Why should recalibrating increase the battery life? The battery is full when the end voltage is reached an no more charge can be taken (4,2v @ lipo) and it is empty if the minimum allowed voltage is reached (should be with Deffy's technology 2,8v?). So why should recalibrating increase battery life?
Greetings, Jo

It's well known that this procedure will indeed produce better battery performance. Most devices have a similar procedure. Even HTC has given some calibration procedures in order to improve battery performance.
How do you enter Advanced Recovery? I can get my phone into recovery but that's all.

Hey,
You have to user Clockwork MOD recovery, and then when inside it go to Advanced, and you will see the battery wipe option.
cheers

lion battery recalibration/recondition was already there long before android even existed...
Since I flashed several ROMs I tried this and I am happy! Battery consumption seems to be better after this workaround. I'm on 1.3 Ghz @ 72 Vsel with my Defy and easily reach an uptime of 2 days, mostly a bit more..
Thanks again!
There will be almost no impact on total runtime, just the percentage meter can become more accurate by "calibrating" the battery. In addition to a complete discharge (I do not encourage you to discharge more than ONE auto-off, you shorten the battery life by discharging below 3.0 V) you need to have a nearly constand discharge current on most phones for this calibration to become really accurate.
What is the effect? Well, not much. Your phone just knows better how much battery is left, so maybe the "empty batt" message @15% comes later. The usage time and the auto-off threshold are not impacted at all.
When we are talking about a battery that has been put away for months without use, you may be right. One charge-discharge-charge cycle may bring back some capacity. But this is not true for any regularly used battery.
If you care about battery life time (in months/years, not a single charge): Charging above 4,0 V has a great negative impact on it; Constantly holding the charge @ 3,5-4,0V may nearly double the life of a battery but you can only use about 50% of its capacity this way.
I'm not sure if calibration/full discharge is necessary/recommended. From many readings calibration is not necessary for lithium battery. Actually it is recommended against full discharge as lithium battery has limited full discharge/recharge cycles.
after doing research on all methods to recallibrate checking pros and cons finally i got the answer brothers...its very simple no need for cwm or drain full abttery kill your batery download recallibrate delete batterystat.bin....all fake bother....just do a simple step remove your battery for 2-5 minutes and than on it....you are recalibrated....simple

take out battery for about 10 minutes. And then try to charge again.
If you will see same problem i think you need to buy new battery.

then buy a new battery ?
buy i new battery bro...and if warranty left than go to service centre the problem also ...is your battery swelled up kya?
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.

rom manager, reboot into recovery or pull battery, and vol. down.

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.

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.

Hi,
Wiping battery stats does not actually do anything
Look HERE
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.
Sent from my HTC Thunderbolt
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.
-k.d.
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
