This is a simple way to increase the battery life in cyanogenmod... this worked for me,..
1. Goto cwm and clear the battery stats
2. Charge the phone to 100% (make sure it is 100% by checking the battery status..)
3. NOw allow it to completely discharge ... do not connect the charger until the phone is shutdown automatically...
4. Once the phone turned off due to complete draining of the battery, charge it and use it normally..,
hope it helps
i have a better idea, bring powerbank 5200ma or up, when u go out. ur device will not run out battery even on hard gaming all day long. like i did

is that a battery?? how much is the cost?
is that a battery? yes n no
yes, because it need to be charged
no, because its not a spare battery that u can plug it to ur device
it's a portable charger, in here indonesia it cost me Rp310000 or around $32

And how will wiping battery stats help??? It basically does nothing to improve battery life.

yep, maybe it doesnt help but it work for me
1st charge 100% while phone is on
2nd reboot to cwm n wipe battery stats
3rd turn the phone off then charge it to 100%, cause it will tell u that ur battery isnt full yet (charge it about 20 minutes or more)
4th turn it on while still charging
5th unplug the charger n use ur phone as usual

I'm not trying to argue here, I'm just saying that wiping the stats won't help improving battery life. So if you say so, on what basis?
Anyways, cheers!
not improving battery life but, correcting current battery stats. it happen when u often switch rom n restore from cwm then u feel like ur battery drain more quickly than usual, so i tried the method i post earlier n it works

The battery stat is wiped to calibrate the battery... We may have to calibrate the battery after every rom install..

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.
Hi folks,
my Xperia Active shuts down at 25-30%. I tried to calibrate, but occurs after few full-charges again. phone is rooted, using latest stock ROM 2.3.4. Any ideas? I mean if you have an experience with it - gimme any hints / step-by-step advises. THX many times!!!
I would try to delate battery cache,discharge it few times and format it.i have had this same problem but after them few steps my batt work normaly.What i think your battery was not formated properly on the very start of using it.

calibrate - full charge and remove the battery charge info file
format - full discharge batter, turn phone off, full charge and than turn phone on?
thx

If you've tried calibrating the battery and thats not work it might be that the batterys faulty. Try a different battery and see if that works.

the battery MUST be ok, as it is only 2.5 months in use in the phone. It worked and after I re-flashed the standard ROM, it worked a few charges and now it went crazy. the Battery Monitor Widget is not able to detect the battery capacity (mAh) and when charging, it indicated 100% at almost 4.00 V, where it shall be 4.2V as 100%.
I will completely discharge the phone, and when it shuts down, will put it to the charger, turn it on, calibrate - erase the battery info, unplug, discharge untill it will completely turn off, charge it with phone being OFF and the, after it will be completely fully charged, turn it on.
will see where the rabbit hole goes...

Hey guyz
I dont now if itis an old topic or a new one that's topic for xperia p save battery
My friends, i can see you have many problems with the batery life. I don't know if any of you has noticed this, but when the phone is charging and it reaches 100%, you shouldn't remove the charger. The phone is still charging even after reaching 100%,sometimes for half an hour. If you want to see when the phone is fully charged, go to Settings-About phone-Phone status. In the first field you can find if the phone is or is not fully charged. Try this and let's see what happens. I hope i can help some of you.
I havent write this topic i have only copy it

It's a program found on the play store search for Battery Calibration
Requirements: Android 2.1+ | Root permissions
Calibration needs to be done after flashing a new ROM, but you can calibrate any time you think your battery is miscalibrated. This program does it by removing the batterystats.bin system file. The OS generates a new clean batterystats file soon, thus any fake information from the previous ROM is removed.
It's suggested, but not necessary, to let the phone fully discharge after calibration, then charged to 100% without break.
Is it the same to do the battery calibration with that app or to just wipe battery stats with CWM?

This and all other programs. which delete batterystats file, not do any callibration! Batterystats file only hold battery usage statistics and automatically deletes when charging reaches 100%! To avoid battery problem, allways before charging, discharge battery till phone turns off!

Good Luck:good:
Battery calibration:
1. Charge your phone to 100%
2. Remove charger and turn off your phone holding power button and volume up button at the same time until you phone vibrates 3 times.
3. Connect the charger and charge your phone to 100%.
4. Repeat previous steps 2-3 times.
5. Remove charger and let your phone turn off when it reaches 0%.
5.Charge your phone and your battery is calibrated and you get some extra battery life!
You also can wipe battery stats in cwm between 1. and 2. step.
Thank u very much all but what should i do iam on stock rom and i have root and busybox and i installed cwm redovery whats shall i do please help me please
Can't you read on page 1?
most people here are changing ROMs...and most of the time people say that some ROMS are a big battery drainer..
some move to other ROMs because they noticed that the battery performance of the ROM they are using is changing..
this happens because all the records on the way we charge are saved on the battery stats..sometimes our battery meter says the wrong information. that is why we have to calibrate our battery...we usually do this by going to CWM and wipe battery stats..
but are we really doing it the right way?
here is my guide to do this in the proper way:
i know some of you are using battery calibration from them the market, but all it does is just delete battery_stats.bin from system..But the truth is, the system is still writing the old battery stats if it's erased online...So the only solution is to delete it through recovery...
this is what you need to do:
1.Install Battery Monitor Widget from Market for Monitoring
2.Charge your phone to 100%
3.When done, restart your phone, but go to CWM recovery
4.Go to advanced -> Delete Battery Stats
5.Reboot, you should get battery about 90-100% (depending how much margin has been wrongly calculated)
6.Open Battery Monitor Widget to monitor the voltages. the maximum voltage is 4200mV for Li-Poly battery. Try to reach that value before disconnecting the charger.
7.Before the voltage graph getting dropped, Disconnect the charger immediately. for me it is stopped at max 4190. your mileage may vary.
8.You're done, your battery is calibrated..
kind regards,
baiclark

Guys!! Wipe battery stats is havent nothing to do with battery life!! There is only info about battery drain of every app and time of theses app. Also battery stats are wipe every time when you charge battery above 90% so this function in cwm is practicaly useless.

For sudden drops to 0% Sony Service recommends that you charge the phone to 100%, remove the usb cable and the battery for at least 10 minutes. Return the battery to your device, turn the power back on and put your phone back on the usb charger until it hits 100%.
nice job
good work man. thumbs up...

Just found this method. Testing it now. Anyone tested it? Is it working?
My Ray's battery went from 25% to 1% suddenly.
the most annoying problem in canvas hd is the battery drop problem.
For some users the battery may drop all of a sudden from 34% to 12% while for some it may be different. For me it was always 34% - 12%.
Now the one important thing that I observed was that when I used to charge my mobile , the charging jumped straight from 76% to 100% . In my view the battery was never charged for the last 20%. And it was this 20% that appeared as the sudden drop.
Now coming to the solution..
Battery calibration and wiping batterystats.bin actually never solved the problem because I tried both.I don't know if changing the Kernel did.
So I have come up with one solution that won't disappoint you..
Follow the steps..
1. Let your battery drain to below 10%.. say 8% ..
2. Charge your battery like u always do..
3. When the battery reaches 100% , do not disconnect the charger, go to System settings and then battery and check the graph..(don't disconnect the charger because doing so will reset the graph).
4. notice the sudden increase in battery charging.
5. Use the phone as u always do and let it discharge to 70% ..
6.Here comes the LIFE SAVING STEP..Now what you have to do is charge your phone in one go..there should be no interruption in charging..If the electricity goes off even for a second..the whole process fails..so prefer using a UPS..
7. Let the battery charge to 100% and use normally.
8. Its my guarantee that the battery drop is gone.
The bad part..
The problem reappears after a reboot.. and we have to repeat the procedure again.
Come on , Don't be PANIC about sudden drop ,First of All letting the battery drop from 100% to 1% leads to fluctuation in battery volt,be aware about it ,Don't use your chd while charging is most important ! if you may use your chd normally like noob users who only use fb.watsupp etc whenever they need ,it won't drop like 30-12% ,fast drain made by users leads to bloat of battery ! high volt ofbattery from 90-100% has corrosive effect if you drain fast then your battery would PREGNANT or fat or swell
DON"T PANIC USE YOUR DEVICE AS A PHONE
