Thank's for reply...is it normal??
if can..i want to extend the battery life..any suggestion for apps??thank's...
If you wanna extend the battery life you should uninstall all apps that can possibly keep the phone awake. more apps needing CPU = less battery life.
also lower the display lighting if you have high battery use of it.

Yes, it's normal
Turning down the brightness will of course help.
Normal seem to be about 12-40 hours. Some apps are badly behaved, others just take a lot of power. It seems there might be a few OS bugs which come and go depending on exactly how you use the phone - some ROMS/kernels seem to help but it is difficult to be specific. Check the BetterBatteryStats thread for some ideas on debugging.
18 hours is decent, it all depends on how you use the phone.
If for 10 hours your phone's screen was on, then ofc this is amazing.

What is your brightness setting? When you are in the battery usage page, click on Display and tell us how many hours the display was on.
You should also check if your phone is on standby mode properly. When you press the awake button and the phone awoken instantly, then you need to restart the phone until it doesn't (e.g. 1-2 second delay is good). I had this problem before and it ate my battery like crazy.
Sleepy cat: my brightness setting is auto & already running for 1hr 38m...since i charge..last night..and the display percentage is 55%...how to reduce it??..
i already reduce my brightness.....
How to reduce battery use by display: Dont use it.
Simply flash the LeoMar75 2.4 RevolutioN Rom. The best rom!!!

I personally found the SolarFlare rom much better compared to many other roms. Have the longest battery life on that.
Use auto brightness, use running services to close what programs/services you don't need(for example I always close skype, yahoo messager, update software, out of milk etc...depends on what you have installed on it and what you don't need ) use static wallpaper and most important charge your phone OFF.

Battery Notifier
this is not the perfect one
thanx buddy for helping but this is not the perfect one. Actually there is one app in the forum but i am not able to find out i did searching but didn't found that app so please any of you have that app or link to that post please provide here.
Wait... how do you mean overcharging battery? Did you tried to clean battery stats when charged? The only thing I've found is this: https://market.android.com/details?id=com.nema.batterycalibration
It has option to notify you when it's 100% charged, but not in background.
Try Tasker with profiles

find this
For ppl who are still paranoid about over-charging their smart-phone battery (which is highly unlikely), this app allow you to trigger a ringtone alarm when say battery reach 50%-100%. This alert you when the charge is completed.
For ppl who face limited power socket for charging (say in some hotel or motel room for e.g) and you have multiple devices that need to use the socket for charging, this app allow you to configure 50%-100% to alert you so you can un-plugged your smart-phone to allow other devices a chance to use the power socket to charge.
To configure, set Ringtone for alert, select the percentage you want to be alerted when the battery charge reach and tap Save. Finally remember to tap Start to start the service.
Important points to note:
- Set screen timeout to be longer so the ringtone can play longer to get your attention.
- Disable any screen lock because it may prevent the app from waking the smart-phone up to play the ringtone.
- With 15 minutes to test the app, if you find not enough time to test, you can get it first and if not satisfied, drop me an email and I will do a full refund.
The application support English, Simplified Chinese, Traditional Chinese display.
Latest version: 1.0 (for Android version 2.1 and higher)

Hey there,
Using: galaxy s2
Rom: Resurrection Remix 2.4 on ICS (4.0.4)
(Though it happened on few other ROMs)
Issue 1:
Often, the time on my status bar will stop updating, and will be stuck.
Going to ROM options, removing it from the status bar and putting it back in will update it once but generally it will still be stuck at that time.
Rebooting the phone (usually) fixes this.
Is there anything I can do to prevent it? It seems the phone's clock is ****ed and not specifically the status bar's clock as clock applications also do that sometimes (Getting stuck)
Issue 2:
If my phone is stuck, after reboot it will generally start with battery percentage 22%, regardless if the battery is full or empty.
Rebooting the phone fixes the issue, but otherwise it takes sometimes hours until the percentage is back to its real state.
Any fix in mind?
Thanks!

battry not showing correct stats
hi you could try this
1. switch phone off
2. put on charge till 100%
3. unplug charger wait a min and put charger back on for another ten mins or so, so it is deffinately fully charged. (it might say 100% but sometimes may not be from my reading around)
4. unplug charger and switch phone on into recovery mode, scroll around and find wipe battery stats. click and run it.
5. run phone untill battery is completely empty then fully charge again (not using phone ie switched off)
dont worry about readings.they will settle down after a few or so of step 5 only ie dont repeat wiping batter stats after youve done it once.
if that fails you could try new battery and repeat steps if prob persists.
also are you undervolting cpu gpu ifso it may just be getting used to the new settings not 100% sure though someone with a higher knowledge may know more on undervolt isues
as for your date and time are you using get time from interweb etc try unticking them i think and are your timezone correct.
hope this helps

For the time problem. Go to settings date and time and untick automatic date and time and set the correct time.
For the battery. If you're running SiyahKernel you can try to reset the fuel chip in extweaks. If you're not just let it settle and it will calibrate itself eventually.
Hope this helps you

Hi Guys,
I am using xperia sola from last twenty days.....:good: but the battery performance is very bad:crying: when i checked my battery usage, analysis came out that more than 50% of battery is getting used by display....so to cut down that i have started using picture wallpaper instead of live wallpaper but to my surprise i came to know that Live wallpaper is running in the background which is still consuming my battery.
Battery is lasting for less than 24 hours.

either the apps running behind the background or the 3G
is the no.1 battery killer
use advanced task killer to kill task or disable those autorun apps

Task killer won't help, those tasks will come back and make it even worst for the juice they use for initation.
Disable data, or use 2G only (turn 3G back on when you really nead it). Or you can search in this forum the way to do it automatically .
For the live wallpaper issue, just uninstall it
Bright
You should try reducing the bright, Hight bright eats all the phone battery...

just choose a static background, reduse screen brightness and usage. Today's smartphones need juice. Consider buying a spare battery

Screen brightness is going to be your number one killer. Also, if you're using WiFi/3G/4G all day long that will kill your battery too. Finally, if you're playing games that use a bunch of graphics that utilize your phone's hardware (openGL, unreal engine, etc.) it will drain your battery pretty fast.
I have seen an article somewhere saying that live wallpapers don't actually consume as much battery as people make them out to be, and i found this to be true, i got 5 days out of my Optimus 2X (no sim card inside) and it had a live wallpaper, what consumes the most battery is the screen itself (reduce brightness to get better battery life while using the phone) and data on 3G (i always turn off data when i don't use it) and i normaly get 2 days out of my Optimus 2X (1 day of heavy usage).
Thank you for the info whoever provided here.

Try or start with this app above and hunt for apps that syncing/updating in the background and basically you need to make a dumb phone out of your smartphone. Disable all autosyncs/notifications in the setting and apps like Facebook disable notifications. Open up Google play>settings and uncheck all default checked settings. Disable gmail/email notifications. Disable auto backup/restore. Disable all location services/vibrations/sounds when typing/wifi or GPS or BT when not in use. Disable data or stick with 2g in standby mode. Find a custom ROM that usually will be much better with battery management.
That's in a nutshell of how I can basically keep my phone draining 1% per hour on standby mode.

Free available n the paid one is awesome... I am not saying saying will get 100% increase but 30~40% INCREASE is observed by me and well something is better than nothing... M using the paid version bt the free one is equally good.. Oh yeah one thing.. Download.. Thn customise.. N forget it because its fully automatic...

I highly recommend GO Power Master: https://play.google.com/store/apps/details?id=com.gau.go.launcherex.gowidget.gopowermaster
It lets you customize power profiles and set "sleep" cycles so that it uses minimal power when you're not using it anyway (I set mine to just be phone/text from 11pm until 7am).
It also has a "smart kill" button on the widget (which you don't have to use) that will prolong battery life by killing apps that are doing nothing. I know there's a lot of argument about app/task killers out there, but it's always worked well for me.
Adjust screen brightness to 0 (dim)
use dark wallpaper
disable gps, bluetooth , wifi when not in use and also air plane mode during night time
and also clear running apps with task manager:good:
Also you could try GSam Battery Monitor Pro, it will show you which process are using %'s of power
Try this one

First, excuse me for my bad english. I'll try to said something and I expect would not to be an offense to you . . . It would to be easy to turn of the phone . . . no?
Of course I have to do something of this things, but If it's necessary to do all of them . . . it would be better to don't have a smartphone . . .

Juice Defender functions only if you have you phone a lot of time inactive . . . It functions turning of your conections in inactivity period and olnly turns it on in few intervals depending of your profile . . . It's very good, but if you want your cell phone conected every time . . . this is not a solution . . .

You are using stock firmware or custom?
If you face problem with battery.. draining like hell..
then these tips are for you....
1. Battery Calibration
2. Control Apps
3. Device Setting
1. Battery Calibration
Don't use any application..
Just charge your battery till 100%.. Restart your phone
without remove charger..Important
after restart (battery show 60 to 98%. leave it on charge again till 100% + 2 hrs. more
Then remove from charger & use phone until battery drain to 0% and switch-off itself
Don't recharge between 100 to 0%.. then try to restart at least 3 time.. to sure drain battery completely
now connect your phone to charger.. after 10 minutes start your phone.
but don't remove your charger till battery goes 100%...Important
(sometime it take more than 4-5 hrs. so better in night) When battery goes 100% ...now you done Calibration..
Technically..
on every restart Android reset Battery (by wipe battery status)
So.. on 100% Android make Maximum level - on 0% minimum level
P.S. Do this calibration on every ROM flash or at-least one time a month..
2. Control Apps
Some Application consume battery do much..
i.e. Facebook, Youtube, Maps, Whatsapp, Viber, Yahoo! Mail / Messenger, Skype, Hotmail.com, etc.
so when you don't use these apps (running in background) kill them .
Better use Browser Bookmark instead applications
i.e. Facebook, YouTube, Yahoo! Mail, Yahoo Messenger, Outlook,
It help to save your RAM also..
3. Device Setting
lowest brightness..
lowest screen timeout
Close WiFi if no need
Close Data Conn. if no need.
Close Bluetooth if no need.
Close GPS if no need.
try to use dark backgrounds..
Try these tips then tell me how your battery work
Sorry for horrible & terrible English

Just one comment on your procudure.
The text as you wrote:
Don't recharge between 100 to 0%.. then try to restart at least 3 time.. to sure drain battery completely
Io-li batteries cannot be fully discharged. POwering up mobile at 0% (withou charger pluged in) just to exaust battery can lead to a permanent battery damage or shortage in its life.
The rest of the procudure may help (or not),
