Have you tried re-calibrating your battery?

Yeah dear I have tried but battery celebration apps required 100% charging for celebration.. but my device has always showing under 60% charging that's why its not works..

If u know any other idea for battery calibration so kindly tell me, will really thankful

Is it in your status bar that it shows the incorrect value?
Try going to Settings > About Phone > Status
It should tell you the correct value there. If it still shows up as the incorrect value i believe it could be a problem with your actual battery.

In your case, you don't need an app for calibration. Since you can't get your phone to show correct status, reboot into Recovery, go to Advanced and Wipe Battery Stats. Reboot phone, Run Wifi, Bluetooth, Torch, Music and anything that could drain battery faster altogether until the battery runs down and switches itsef off. Try recharging and see the result.
Hope it helps.
Cheers.

Thank u so much to all of u..
I,ll do it and see the results.. :beer:

i have been experiencing the same problem with the battery .. doesn't seem to get past the 70% mark. I started noticing this few weeks into using CM7 ( currently using CM7.2 RC3 http://forum.xda-developers.com/showthread.php?t=1698029 the issue still remains) At first i found out that if i reboot my phone after putting it to charge , it would charge all the way to 100 %. But slowly that too started fading and now nothing i do gets it above 70%. even got a new battery to no avail, and i cant get more than 5 to 6 hrs with the battery .. the battery drain is incredible
am i using an incorrect kernel or something ?? any help is appreciated .. thanks in advance !

My opinion is its something to do with your phone itself, if it was software/kernel related we would all most likely get the same problem as we are all using the same piece of software.
Sent from my GT-I9100 using xda premium

I too have this problem mine does not charge beyond 79% sometimes 75%. With my experience this is too do with the kernel that CM7 uses. If I restart the device it will show 100%.
If I go back to the stock kernel the charging goes all the way to 100%.
Either my charger has broken or its the overclock-able kernel.
I have tried every other method out there.
The battery performance is good BTW.

Quick battery drain

Hey everyone ,from when I rooted my device my battery is draining very quick.before I rooted I used to charge it once a day.

What ROM are you using now?
Are you using a Live Wallpaper?
Also mention something you've done after which the battery drained faster... (something done after rooting)...

I don't know and im not using a live wallpaper.but when I rooted the first app I installed was set CPU and its on highest frequency,also when u finished rooting I remember that I entered cmw and flashed an update.zip which came by itself.could you please give me a battery saving ram?

I think its definitely setCPU. When i installed it my cpu freqquencies would change every second between min and max frequency(no matter what governor i used). The result:excessive battery drain
I think its because stock kernel doesnt support overclocking(or even underclocking)...May be the devs could explain it
After i did a factory reset, battery is ok now for me. No battery drain when kept idle for a night:good:
P.S. Also before reset my HW decoding(in video playback) wasn't working(now its ok)....any1 experienced this too?

The problem isn't setcpu the problem is that he set it to 2ghz

I think it is the setCPU too, try to use no-frills, it is a tad better in my opinion, but stock kernel doesn't like non-stock settings that is for sure.

I upgraded to rc2.1 cz they told me that the battery drain will decrease, but its still the same

how often do you use your phone and what operations do you do with it... are you always on full brightness? is your gps always on? are you always on wifi or bluetooth? some things to consider that may take chunks of battery life..

you need to reset the battery by the sounds of it, empty your battery tonight, run some games or put youtube on or something....there used to be an app on the market that would run gps\wifi\brightness all max etc and empty your battery for you....not sure if it's still there.....but when you do root you can clear battery stats which will make your life easier....but yea empty it, charge it while it's off and HOPFULLY everything will be fine for you also as a sidenote, i charge my phone with wifi on and internet radio playing in the night and charges to 100% fine

When should I clear the battery stats?
Sent from my HTC One V using xda premium

it's known to reset the "capacity" of battery, but personally i don't believe it.
Use program BetterBatteryStats and see what's keeping your mobile phone awake, and also install CPU Spy to see on what frequency is your phone mainly working.

[Q] battery drain problem JB back to stock.

i updated to jellybean LI8 from stock t999 LH2 version, but because of super heavy battery drain i flashed it back to LH2 thru odin.
However i still get same heavy battery drain. i use up 10% every 1 hr just with screen on. before i used up about 3~5% for 1 hr.
i was able to get about 14~16hrs with normal use before, but now i dont think i can even get 10hrs.
it seems that the sim card area gets hot whenever the screen is on, and cools down when off. before flashing my phone was never heated
unless i was playing heavy graphic games..is there a way to completely flash the system files? or to fix this problem...pls help. thanks

Your numbers don't make sense. Need a screenshot.

I also observe the battery drain.

yes the screen % is fine so i dont know where its draining the battery...
i think something wrong with system file because my phone really didnt get warm just from having the screen on.
is the method i reverted to ics correct? or is there another way to completly reset/overwrite my phone back to stock?

If your phone is working, your method wasn't incorrect. If you flashed the stock firmware through Odin, that's as virgin as it gets.
Battery Info and KakaoTalk are obvious culprits. Tell me about your wifi situation. Are you connected to a wifi network?

yeah usually i leave wifi and kakao talk on most of the day but it doesnt drain battery this fast...it just messed it up after the jellybean update., it was 100% this morning, 4 hours and now i got 60%. usually i would probably still have around 85%+

I'm in xquizit v26 and observed that I'm not getting a deep sleep and the battery drain in less than 5 hours. I reflash the rom with full wipe and still have the same issue. I step back and investigate what cause this problem. It seems that when I flashed the kitchen v6 with open vpn cause not to have a deep sleep. With out the open vpn I was able to get a deep sleep. On the first cycle I was able to get the 15hrs battery life. I will continue to observe this because the battery behavior can only be observed after 3 days.
I tried to post this in the ROM section but XDA wont allow it because I only have less than 10 post.

If you can go without, try uninstalling those two apps and see if it settles at all. Also get cpuspy to see how often the phone goes into deep sleep.
Sent from my SGH-T999 using xda app-developers app

okay so i jus instaled the cpuspy and saw that theres a lot of deepsleep so i guess theres no problem..?
and i think its not the app but the thing with screen. whenever the screen turns on, it gets hot and the batt uses alot..
i tried re-flashing using odin while ago but still the same.

I would suggest flashing wildchlds XquiziT or DJintrigues Frosty JB. They both have done very good jobs at getting more out of your battery while still remaining stable. Being on the full stock leak i doubt you will easily find a way to acceptable battery life. At full stock i kind of remember LI8 being one of the worst for battery.
There are actually multiple causes, some depend on how you use the phone.
Another thing you can do to help hunt it down is get Better Battery Stats.
Also in Settings > Dev Options check show cpu usage and itll tell you what processes are using the processor in real time. You will likely see 2 or more that seem to stay at the top of the list.

i checked the XquiziT's ROM and i think lots of people are saying the battery problem was solved so mayb ill try it with this one, however when i went over the posts it seemd that theres prob with the kitchen? thingy and they took it down. is it possible to jus flash the XquiziT Rom without the kitchen features?

Yes you can flash rom without kitchen. Hes actually working on a new release hoping for today I believe.
Kitchen was taken down due to possible bricks when using wallet and mobile odin.
Also, battery problems are not 100% solved in either rom but are close!

hey thanks for the replys...
ive tried to flash the v26 through recovery boot menu but it says E:verification error. i think its because i flashed back stock by odin, how can i solv this problem?

Have you reinstalled twrp or cwm? Stock recovery wont flash that.
Sent from my SGH-T999 using xda app-developers app

Remove the battery for 5 min...and then check for the drain. Mine fixed itself up this way.

okay so i installed twrp and did the install but still same prob with the heating battery lose. i will try few more wipeout+install and the battery takeout thing too and post up

[sds] could this be sds

I don't know if this is sds or something else plz do help. What happened is I was using phone phone to watch bell tv when my network kicked out and said no sim card. My phone was really low on batt but I restarted my phone and pulled it in but when it would restart there was no batt charge going on and the phone just dimmed out. It took about three retries but I got it to start charging. I don't know if this helps but at the time of all this the batt temp was over 41c. Could this be sds

How do you get into recovery when it's stock and what's the difference between recovery and download mode
Sent from my SGH-I317M using xda app-developers app

recovery is just some commands such as wipe data, cache install something with sd and so on and it apperars by oppening the phone pressing power+home+ vol. up
download mode is a special mode used to flash mostly with odin (although it is used with kies too) and is the same procediment but with volume down instead of up key pressed when boot

[Q] (Solved) Strange issue: Phone going in Boot loop when removed from power source

Hi Friends,
I have a GT-N7100 and i updated it to 4.4.2 by taking the files from Sammobile N7100XXUFND3_N7100ODDFND2_INU. The phone was working fine till today evening. Initially it started to randomly reboot. Then suddenly it went completely into boot loop. But strangely when i connected it to power source it booted properly. I did factory reset, ROM flash multiple times and still the same issue persists. Can some one guide what might be the problem here?
I have done wipe cache, wipe dalvik cache and factory reset also multiple times.
Solution: Seems the battery is gone Kaput. Also i believe the reason is due to a high voltage charger i was using for quick recharge. lesson learnt... Dont use a high power charger

will this be a battery problem, as the phone goes into boot loop only when removed from power source

But I don't know exactly.
