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:

Sounds like your one of the many people with this fault, http://forum.xda-developers.com/showthread.php?p=26658803, I haven't come across a quick fix for it either.

This is strange... Changing the battery is not an option as it works well... Have you tried flashing another ROM?
If I may ask, did this battery issue started when you flashed CM7?

Its happened to quite a few people since I've been around this forum, dont think anyone has pinned down a particular reason for it happening and the only explanation from HTC is that its a mobo fault........
Sent from my GT-I9100 using xda premium

May be its a mobo fault but this is truth that I am facing this issue after flashing cm7.2..!
I have been told this rom working almost perfactly and such a nice and smoother one but before I was used Sunabh Rom v.1.1 by Vibhus which is also nice rom and had never facing issue like this on my previous rom..

Try revert to your previous ROM and see if your battery shows its true status.

Its not yet possible.. I have been delete nandroid backup of my previou rom

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.

Why is my battery showing this?

My phone was working fine, but now this is my battery usage. I have restarted twice and it still shows like this.
Plus my CPU has been running for 248 days or something.
(Guess my pics didn't upload)
The battery is showing android os as 100% off my battery usage.

Alright, I'm a noob, I was with you up to reboot your device. "Go to recover and delete battery stats" was where you lost me. Maybe some more detail or a hint on where I can look to learn about it would be super helpful. Thanks.
Sent from my SAMSUNG-SGH-I317 using xda app-developers app

Are you rooted at all? Installed any custom recovery? i.e. CWM or TWRP. You need to have installed a custom recovery to delete battery stats.
As for the android OS usage, that's very weird. Try searching it up on google and see if any results pop up. You could delete battery stats but not sure if that'll help. If you'd like to know how though, let me know.

If u r rooted and dnt have a recovery, download a app called 'sdmaid' frm store, and u wil get an option of delete bat stats!

Not rooted, yet, but plan to add I learn more. Well full charge tonight and see if it clears. If not, will search for similar issues as you suggested. Thanks.

I had that happen to me when I first bought the phone. Was terrified I would have to return it. Just charge it to 100% and reset it. No reason to put it in recovery or anything. That fixed it for me.

[Q] Xperia S modded battery issue

I am new to the custom rom thing but I am loving it because I was about to throw this phone away "Xperia S" but after playing around with roms and kernels I am back to liking my phone again. My question is related to the battery, I added the PAC rom V18 and I also added the Nova kernel V5 but my only complaint is the battery is drained very fast that it doesn't go through the day, I am an average user so I don't listen to music or watch movies. Is there a solution or a kernel that can improve the battery life.
Thanks

Follow these steps:
1. Use your battery to 0%
2. Charge it to 100%
3. Go to CWM > Advance
4. Wipe Battery Stats.
5. Fix Permissions (This may take sometimes).
6. Again use your battery to 0%
7. Again charge it to 100%

I looked for wipe battery data in the advanced tab in CWM recovery but I didn't find it

Battery drain by unknown usage

Hello guys,
I'm having issues with my battery when using the same ROM more than 2 days. I explain myself, my problem is after a complete battery cycle (from 100% to 1% then charging...) my battery drains drasticaly (look at the screenchot). I did a reboot and it dropped from 95% to 30%. It happens to me on these ROMs (Rootbox, Carbon, SlimBean, Illusion...) I use KT kernel and sometimes BMS but same result. So i dunno if the problem comes from the ROMs or the kernels... I will look further into better battery stats to see which app is causing this.
Thanks for helping and sharing your stats !

I would try a full cycle or two with the stock kernel.
Or if you want to go one step further. Backup everything, nandroid and Odin back to stock and try a full cycle on that.

You could install Wakelock detector, [https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector&hl=en] maybe its some crazy thing that eating battery.
Try using intellidemand as your governor on kt kernel, i was having problems like you until I used that governor.
Hope this gets resolved

After two or three charge cycles if your battery problem persists, it's most likely an app draining your battery. Or worse yet, your battery is shot.

I had the same problem with an Xperia Z. I tried all the tricks in the book but the problem persisted.
Ended up taking phone to the retailer. The problem was a faulty battery.

Either your phone's battery is dead, or the battery is not calibrated correctly
