it's easier to help you if you post the screenshots

charge your phone 100% after your phone drain to 10%

settings > battery > take screenshots of the whole list, also of the graph, also tap on the top 4 items of the list and take screenshots, post it all here

yeah if you just updated just use the battery until 0% and let it charge to 100% like 10times, than you will see the difference, when I updated I was watching battery 1% every 10seconds, 1week after my phone lasts 2days easily, 3 if I dont use 3G or play games

it seems to be normal. remember that certain apps

taskillers, battery, ram apps and antivirus drain a lot of battery

and if you are using wifi or you leave it on, there are apps that are constantly connecting and thus draining a lot of your battery

My brandnew Xperia P only lasting 2-3 hrs!!! (after an update) while listening to the walkman or running any other apps, Android OS 40-63% average, about 6-7 hrs in standby wit all apps disabled! wit very lil use, i was carrying too fones (w995) cos i cudn go anywer without battery dyin out, so i reset the settings then did a factory reset an to my surprise its bin a Mega Improvement! Android OS averages between 8-15% now an ive bin getting 18-23hrs wit average use an the OS hasnt been higher than 15% this is my 2nd wk with the fone now so i hope its sorted now???? P.S Havent used Extended Battery Mode Yet either so it shud be even better eh?:smileywink:

Hey Iiika7, few days ago my fone drained from 100% to 13% in 48 minutes wit the walkman playing an data enabled, but not connected to the net, so i decided to to do a settings reset? but to no avail, so I tried a factory reset and as soon as the factory reset was finished the battery level IMMEDIATELY!!! went from 9% to 53%!! and since then its been lasting ages! You will find the reset options in settings under Personal in Back Up and Reset! this Screen Shot was earlier today its now showing 48% with 11h 38m 19s ...a major improvement ive used lil net ova wifi an a few calls today, so for a smartfone its a lot better than what ive had previously? hope you have similar luck!

ilgreco112 is right. I have experience same issue with i bought xperia and imediately upgraded to ICS. You have to charge and discharge couple of times and 2 days will not be a problem (of course not under heavy usage)

After updating my phone to ICS, i did a factory reset, and then activated extended standby mode, which made a huge difference to my battery life, now it stands atleast one whole day with moderate usage.

the main power drainer is the background processes, one could limit the processes by doing the necessary changes in "developer options", it depends on person to person whether they want processes running or no, of course thr is a down side, you wont be able to resume to the activity once you exit the application if you have selected "no background process".

I use "Elixir2" and disable "Unsupported Headset Notifier" process. The process consumes more than 23% of cpu resources on my Xperia-P, after disabling I could use my phone for around 36 hours with moderate use.

I am on ICS 6.1.B.0.544

The Android OS should eat only 4-8% of the battery.If it eats 10,15% or even more,there is a problem with the software.And thank you for mentioning my extreme battery life in your earlier post:smileylaugh:

hey,well i did the factory reset,but it didnt helped me,so i had to make the hard reset too,which erased everything on my phone ,so be sure u make backups on your computer.

so thats for the hard reset:

Press power + up button and hold for > 10secs and let go when you feel triple haptic feedback.

and for the fabric:

From your Home screen, tap .
Find and tap Settings > Privacy.
Tap Factory data reset.
Tap Reset phone.
To confirm, tap Erase everything.

and my phone is working fine ever since then.
