"please read any comments as some are useful"
Before you start doing this make sure you have time on your hands.
Follow it step by step...
Read the entire set of steps and comments first.
Do not deviate.
If you are having issue's with it not charging fully. "70% to 90% and no further." then begin at step 7
If you have Xrecovery installed wipe battery stats first to reset the battery cache to the defaults.
This post will not talk about apps or any odd mods.
It's here to clear up on how to properly optimize the battery in your phone.
The battery has a cache file used to set the top and bottom battery level.
Today i am gona teach you how to set it correctly using nothing more than your phone and charger.
While doing this it will also properly "cycle" the cells.
This leads to the final part of my guide.
Damaged batteries.
If your life on the battery when using only airplane mode.
Is very bad.
Then you should be careful.
1. Check for any swelling or deformation on the battery.
2. Battery gets very warm while charging on standby in airplane mode.
If found Discontinue guide and replace with new battery.
And calibrate again from step 1.
-Enjoy
1. Charge your phone fully to 100%
2. Plug out your charger & switch off your phone.
3. Remove the battery and plug in the charger.
4. Re-insert your battery
This is sets the top end battery parameter to a higher state allowing for further charging.
Should read 88% now.
5. Keep a eye on your phone as it charges!!!
Remove the back plate and feel if it's getting hot "it should not be a issue"
6. Repeat steps 1 to 5
Repeat this no more than 2 to 5 times till the battery will not charge further
A few extra may be required...
The battery may get stuck at 70% to 99% "most of the time 88%"
The cells have now reached full potential
IF in the case that it keeps charging after the 4th time your battery is fully optimized Enjoy, Continue with step 7
7. Let your phone run down it's battery
Don't use the phone aggressively
Leave it till it switches itself off
Now it has marked the very lowest point of the cell in the cache
8. Don't leave the battery empty, begin charging as soon as possible.
If your phone does not switch on right away.. relax.
Just leave it on charge for about a hour "will switch itself on"
9. Repeat steps 7 and 8 a few times.
You will notice each time that the battery may charge just slightly bellow 100%
Getting closer to 100% each time
10.Soon it will read 100%
It has now marked the top charged point for the cells
If step 7&8 does not bring the battery to 100% use the battery calibration app from the market.
Don't rush.. take it calm and easy.
Enjoy your properly set, fully optimized battery.
If you are planning on flashing a new rom you can copy "data/system/batterystats.bin"
And copy it back once you are done flashing.
This way you don't lose the optimization.
The battery does have over current protection it should be just fine.
Still be careful.
This knowledge is based on direct experience building electronic projects for over 23years that require rechargeable cells and the nightmares i had with a bad x10 chipset..
REMEMBER THAT I'M NOT RESPONSIBLE IF YOUR PHONE BLOWS UP ETC.
:- final edit 2011/9/12 -:- 3:09PM
Added extra on damaged cells.
Found a few more mistakes and required details... edited.
Added a line for Xrecovery users. <<< removed this.. it's crap.
Thank you xcxa23 for showing me where the battery stats file is.
LET me MAKE this 100% CLEAR... wiping stats = nothing
This guide cycle's your battery, by correctly setting the upper and lower parameters of the cell.
[GUIDE] X10 Battery Calibration arent this the same? if you wanted to do it manually, u can go to data/sytem and delete the batterystats.bin file. but of cos u had to wait till 100% before u delete the file
nice one OmegaRED^....
ahaks..i already read it somewhere at Development Section..but never try it..

So it was necessary to create a whole new thread instead of lets say, PM'ing me so that I can add the missing information? Either way, this really works to improve the battery life, and the more people know about this, the better. Going to thank you anyway.

Performed as said in the OP along with a full discharge and recharge and I'm getting a lot more use out of my phone now. Use it a lot for listening to music so the battery drained quickly but not any more.

Nope.. it does not matter.
This is not a hack or a trick.
It's simple li-ion battery science.
If it still has problems then your battery is already optimized and your problem is completely different.
This 7% in heavy usage or light usage or standby?

it's because u wiped battery stats on the low battery charge and didn't make a battery calibration. I had the same problem until the calibrating using another method (for me is easier, but this topic shows another way, which can probable be very effective )
Thx OP, although it was stated in another thread like noticed
Someone on XDA also done an Android app, Battery Calibration, easying the process of battery calibration/wiping.
I don't use it for calibration, just to get battery health in mV (even if you can grab it from Android System Info, Android Assistant, etc).
Still using the good ol' method of xrecovery
What is battery calibration? How to do it? Answerer will be thanked..

Battery calibaration is usually done when you flash a new custom rom!
It is done to wipe the old battery stats and rebuild the battery stats so that you can get better battery life.!!
It can be done using a free app from market battery caliberation.
You need to charge you battery to 100% to caliberate battery and after that make sure you drain your battery completely.
P.S Choose a title next time that represents your problem so that you get best help from all the experts here!

Thanks.. Will make sure about that next time..
Nothing
Don't mad at me if I said wrong ................
Why battery life so fast?
- Because all of we are installing( flashing ) every roms that we like......
- The first time when you change your phone's version , that time is not much for your battery....
- But when you flash one after one , it effects on battery life...... you know why?
- Because All of we want to try every rom ( the main problem is we want stable rom for daily use )
-If this rom not stable or get FC want to change another rom... some they don't want to fix that problem including me
-How to fix battery problem?
It's simple
If you have stable rom for daily use , buy New battery (original battery)
and if you want to use for changing rom u use old battery , and you think it's stable rom, put new battery ,,,,,,,
I think I solved battery drain problem
Hit Thanks If I help you
I will 8plain why I say for some almost every roms ..... After I cameback from my work
I can't see the text behind the smiles...
I have a better solution... don't flash a new rom every week, flash one and stick with it.
Also let me be the first ass to say WRONG SECTION!

This is the most stupid thread i have seen.

Remove this please,
Interesting use of Smiley faces here...
well man, i don't know if you tried this but... in market there's an app called, battery calibrator, is obvious what it does, isnt it? ok, if you follow its directions you're gonna have a good battery life, sometimes removing battery stats from xrec manually does not work very well, but, if you do it through this app, it works very good, just charge your phone until it gets 100%, click on calibrate (into the app, it removes battery stats), then unplug phone, use it until it drains the whole charge of the battery, i mean until it turns off, if you really needed that calibration, you're gonna realize that the last 10% lasts, foreveeeeeeer, what does it mean? that our phones, never get the true 100%, maybe it gets about, don't know, 90% but, the OS thinks it is fully charged, so it begins to stop charging. When the phone is turned off, charge it (i dont know if turned on or off, i do it off, the app does not say it) until it gets 100%, then turn it on, enjoy.

Do you think is it the most stupid thread in XDA?
I didn't say this is the best thread in XDA
Even you know how to do this .... Some of our developers are ( new members )
still don't know this problem
Is there something wrong with my 8plaination?
If I'm wrong plz 4give me .......
I want to request forgiveness from you
I just intend for new members who are still don't know about battery life
Do you know why?
Some of deps are thinking that Example: Wolf's rom .... they flash wolf rom
and they feel rom is so fast but battery life very fast finish....
then they think this rom we cannot use because battery life no good
then they changed another rom like Achotjan's rom again....
So ...... battery life is slowly and slowly down after rom and rom......
But they didn't think that because of flashing roms......
Thanks Bro for yours
cool story bro
Troll story bro
brool story co.
-_-
Can we please just close this thread.
any look inside the barterie?
normal bateries from computer handys and .... have a eeprom that save data from!!!!
or you could just wipe your battery stats, and use proper engrish
I think OP shall be best friends forever with Mr Berma, you guys will have a lot of common language together...lol

The x10 only has a heat probe and the driving circuits for the cell.
The Chargemon handles the battery statistics by checking current flow and voltage.

Itz truely helpful dude.....
Specially for new members, like me.....
Truely appriciate ur efforts dude...
I found a guide somewhere on the internet on the best way to calibrate battery stats on a rooted device when I had my old hero and I use it a lot to this day so I decided to share the best way to do it here. If there is in fact a thread about this already in our forums I apologize but I could not find one. So here it is.
Step 1.
First and foremost charge the phone to 100%(Even if it says 100% wait about 5 minutes or so just be sure.)
Step 2.
Once it is at 100% go into data/system (using root explorer) and delete the batterystats.bin file there.
Step 3.
Unplug the charger and reboot to recovery, wipe cache and dalvik cache and wipe battery stats once more while you're there just to make sure they're gone.
Step 4.
Power the phone down and plug it back in. Charge it to 100% while it's off (the battery bar can be deceiving so even once it shows it's full give it five more minutes or so to be sure) and then power up.
*As a side note, if you are using stock kernel, or a kernel without the 100% battery mod then your only going to be at 96%. Thanks to Glennkaonang for reminding me of this.
Once it is booted to the OS you should now see that the battery bar is at 100%. (please note that when it's going through the "Android is upgrading" thing it can take 1 or 2% off the battery if you have lots of apps)
Final step.
Wait for the phone to die completely (to where it shuts off on its own) and let it charge to 100% while the phone is off and power it back up. Do this step at least two or three times.
After that you should have a fully calibrated battery and have no more messed up battery reporting.
Photo of my average battery life just for fun.
Everybody enjoy! If this helped you please hit thanks!
*Thanks to whoever it was that wrote this up in the first place. If I knew who it was I would give proper thanks.

Unless my batt % reporting goes wonky between reboots, I don't ever wipe stats. It doesn't necessarily increase your battery life, but it does appear to fix incorrect reporting.

Wipe batterystats and fix permissions working well after each kernel change but I will give a try.

I didn't think it would improve battery life either but it does. Maybe not a HUGE amount but it definitely does help a little. Plus it will give you the correct percentage rather than showing 100% when it's really only 95%. Lol. Anyways, to each their own.

Maybe it's not working on your phone because you're using the stock kernel which doesn't have a Battery Life Extender cosmetic MOD.
It's just cosmetic, actually it's still the same 96% as all other Android devices do.

This doesn't do anything other than fix incorrect battery logging, it DOES NOT increase battery life in any way.
Not even a tiny bit. Nada. Zip. Zero.
Dianne hackborne covered this on Google+ and said repeatedly that it doesn't extend battery life in the slightest. She would know as she wrote the code I believe.
Placebo effect in operation here. Plain and simple.

The only reason I can think of is that you are looking to stock up on thanks.
I did this before I even found this thread, save for I use a Battery Calibration app from the market instead of deleting the .bin file. (App does it for me.)
This was the result.

Great guide! I haven't saw a calibrating guide either. I think it should be sticky!

I wasn't trying to troll your stuff. I appreciate that somebody created this guide (albeit now proved to be ineffective/useless) as an informative resource for others. That being said, this information is easily found everywhere, especially with search.
Please understand, if everybody bumped a thread they created every few days because they thought it was useful, nothing new would ever show up on the first page of the forum. It would be the same threads appearing over and over.
I wasn't trying to offend you, I just think that bumping dying/dead threads is counter intuitive to growing this forum community.
Thank you.
It is in a sense misinformation though. It doesn't calibrate the battery, merely wipes androids battery usage statistics, which are only for reference to the user not the system.
Although included, the only pseudo calibration is charge fully, discharge fully then charge fully. This process wipes battery stats anyway.

I have never calibrated my battery and get almost exactly the same battery life as what you are getting. All this does is wipe the stats.

Just Flash It !!!
I have created this thread so that I can help people with battery drain. I will try to avoid the "too long didn't read" problem by making it as small as possible.
Battery Drain : Battery drain refers to a sudden and unexplained draining of the power from battery sources in an area of paranormal activity.
1)Charge Phone Fully to 100% Using your computer.
2)Restart and Go to CWM Recovery.
3)With the charger still plugged in, wipe battery stats and dalvik cahce (In advanced options)
4)Unplug and Reboot and you may see a slight decrease in the battery. Charge it again to 100%
5)After fully charged, pull out the power then use heavily until 0%
6)Now charge it up again and remove the battery.
(OPTIONAL PART)
7)Put it in a Zip lock bag and then in the freezer.
8)Leave it for 6 hours.
9)Remove the bag and wait for battery to reach room Temp.
10)Put battery in phone.
11)Use the phone like normal and make sure you drain it to 0% before charging in the future.
If this helped, do not forget to hit the thanks.
Nice guide. I hope it helps new users here. :thumbup:

If you get 6 days of battery you have no business replying in a battery drain thread!
You came here to point out something out to the OP which you haven't tried? Why didn't you try? Why did you then point out that his idea should be optional if you hadn't tried it?
How do you know lots of people haven't tried his idea which actually does help?
I've tried it and it does work - get used to the idea that you don't know everything 2010matej..
Again, you get 6 days battery 2010matej - 3 times more than everyone else on XDA so you have no business replying in this thread as your phone has never experienced this issue and you therefore are not qualified to speak on such subjects!
Couldn't have said it better.
Nice. My battery now lasts a but longer. Thanks. Could you put more pictures in this otherwise dull guide. I am not great with reading large ammountz of text.
