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
Sent from my HTC Wildfire using xda app-developers app

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:

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.

How about screenshots without the volume indicator? You can also try GSam Battery Monitor from the Play Store, to get a little more information on what is eating the battery.

Did you install any app after or before update? Main reason for all drain is from app.

What's your screen on time.

Looked kinda like liteflow might be causing problems?
Cell Standby i think is the one that is coded wrong and is lying, ignore that one.
If you press Android System in settings, battery it will show you the top components being used
Also in dev options look for and check Show CPU Usage. It will show whats using the cpu in the top right of your screen. Watch for what stays in the top few spots in the list.
There may have been something that didnt like the update. Try first uninstalling apps and if that helps reinstall them clean, no data restore. If you continue to have problems backup all data and factory reset. Start clean.
If all else fails use odin to flash the full LH2 fw.
LH2 should be a fairly stable build. Most have no issues and many get outstanding battery life. Im willing to bet its either an app or the way you updated or both.

Yesterday before i delete liteflow the android system was always ontop of the list but now it is at the very end i hope that it was simply that because i have way too many apps to delete and re install :/ but ill see how it goes today i got root and cwm so ill probably odin the lh2 as you suggested ..

That's really not THAT bad for a screen on time. I saw your screenshots in the OP, and you were down to 80% in only two hours of being on the battery, but you had the screen on for almost an hour of those two hours; 20%/hr for the first few hours is pretty normal. It's not stellar, but I wouldn't say it's an epic drain that being said, I'm sure you could squeeze some more juice out of it, and prob is just an app causing more drain than usual.
Also when doing a screenshot, it helps to hit the power button first, then the volume, so you don't get the volume pop up every time.

3:30 screen on time it's good no matter how you use your phone. I got 2.45 hours on screen with 1day and 6 hours. I've had issues with liteflow and battery as well. Others say they don't, it seems to depend on how you set the phone and liteflow to work.

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!
Sent from my WT19i using xda premium

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.

Might be a battery calibration issue. I know there is a calibration app in the play store but you need root in order to use it. Ive used it on my burst to calibrate bat info, so it should work on the ion.

Get the back up and restore app from the sticky thread in the dev section (I think that's where it is) instal it on your phone they get flash tool click the little padlock icon it will help you root when it says click restore in the app push it and wait. It will restart then say it's done and you're all done.
