Have you tried installing current widget to see what is exactly happening, or how much voltage is going through your phone, even though it's sleeping? (ie, screen off)

I have not tried yet

This happened to me a few times (with almost no apps running) on RC7. Updating to 2.01 seems to have fixed that for me.
If that doesn't help, try using a different kernel and/or a different radio version and see if that works for you (we're reduced to experimentation as nobody has ben able to determine what exactly causes this issue).

I'm well impressed with mine. I went to bed with it fully charged, used it a bit in bed, always play a game and check the forums. Not plugged in at all and woke up this morning and its still fully charged!!
Amazing, since I have yahoo messenger running always. Been using it a lot since I woke up and now on 96% but I know its mainly the screen that uses a lot.
Brilliant ROM tbh

See if this helps:

well it's not really going to save your battery life, it just lets you see when/how the battery is being used up

Yes we can atleast know what apps are eating our battery.

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..

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..

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.

Booting problem

My xperia play wont boot, It only flashes a red power light only when charging. Previously my battery ran dry now when I charge it only flashes a red light. I tried charging it but no difference. I tried another battery it still won't boot, I went to the extent of trying my battery in another xperia play and the battery works perfectly in it. I'm stumped plz help

You may have bricked it. Have you tried installing any rooms lately? Consider flashing back your stock firmware with "flash tool".

I have a stock device that has never been flashed or tampered with. Does anyone know what the flashing led mean?

If it's never even been rooted, then you should take it in for repair. Maybe a hardware issue.

Maybe if he researched but oh well, this what I have and sometimes it indicates a hardware component is damaged meaning find out what it is,
you should:
Go to your phone provider and ask them do NOT MENTION ABOUT ANY ROOTING OR BL UNLOCKING.
Find out what problem it has .
Or never use it again (Dont do it)
In my case the digitlizer "Screen" is broken, because back in march I used to boot my phone and the screen wouldnt sometimes work of course there could be another problem but...

Yea I realised I tried turned it on with the battery in the wrong way. I realised it didn't come on and when I fixed the battery right it still wouldn't come on. It just kept flashing the red light only when I tried to charge via USB or wall charger

Yep

Battery status jumps from 70 to 100 ??

My Desire battery while charging the status jumps from 70 % to 100% immediately.
I have been using battery calibrator application.
If the battery is fully charged, my desire turns off at 30%. That means in anyway my desire only uses 70% of the battery.
:cryingls help me

try this
Charge till full when powered on
power off
charge till full again
boot into recovery
wipe battery stats
boot and continue to use as normal

Thanx... Will try this...

Sorry.. I missed the last step in my previous post. Allow the battery to drain completely before charging again..

yh, in the app once u check the boxes in settings and set the values in learn prep, turn on learn mode and drain ur battery, once it hits the value, a popup screen will say learn mode detected, plug in charger. (or something like that) just have the charger ready coz u only got a few seconds to plug it in then it shuts down lol

Nothing works for me... I followed the battery calibration steps.. But fails.. Still have the same issue...
Sent from my HTC Desire using xda app-developers app

Do you have these problems when you charge via usb or directly from the plug? As the second procedure is much faster, you can have some erroneous battery capacity readings from time to time, especially in (not really old but still bit) aged batteries.
Try before using the calibration tool the following: When the green LED appears, sign of a full charged battery, unplug your charger and turn off your phone for 3-4 minutes (you can even pull off your battery for a while). Turn it on back on, plug the charger and wait until fully charged. At this point reset your battery stats through the calibration app.
edit: oops, it is essentialy the first solution posted but without going into recovery. The calibration tool does this automatically for you.

I have the opposite problem
My charging is quite accurate but while discharging, the phone suddenly dies at a random battery level below 20%, without becoming close to zero

Batt started drainning very fast

Guys, I don´t know what happened but 2 or 3 days ago I started noticing that every once in a while my battery starts draining super fast. I mean 10% in 20min. I went to bed yesterday with 67% and when I woke up I had zero battery. I notice that when this is happening the phone gets really hot. I didn´t change anything on the phone but I did get some updates these days (1 small system update, facebook, smooth calendar, facebook, whatsapp.....at least I think these were the ones). Any ideas what might be happening? It´s random thing. Yesterday it was good all day long and then at night it happened.
I´ve just tried doing a factory reset but nothing happened.

Sometimes an app prevents your phone from going yo deep sleep. Install betterbatterystats. It shows which apps are causing wakeblocks. Uninstall all apps. Also, which rom and kernel u use?

When I go to power and then usage, the biggest consumers there are "Android System" (54%) and "HTC Sense" (24%). I´ve downloaded Gsam Battery Monitor and it tells me sreen 50% and app usage 46%. When I click in app usage it tells me Android System 20% and Kernel 9,6%.
I have no idea if these numbers are excessive or not.
I did a factory reset and I´m not charging the phone to check out how long it takes to go down from 100%.

You can only do this with an unlocked bootloader and have flashed a custom recovery.
It's all in the 'One X All In One Kit'. Search for it .

So you think that when you are at 100% of your battery, you suddenly get access to the recovery?... (this is what you literally say)
Or did you mean to say that your battery stats are wiped when the battery is at 100% .
Still I think that the second explanation is one big whoop, since my battery used to drain life too with a dubious combination of kernel, recovery and ROM. A fully charging of the battery (which I do every night) did not make this problem go away.

Wiping battery stats does nothing. It's already been shown. Search Google. It's not going to magically make your battery lady longer

In fact wiping the batt stats will not make your phone last longer on a full charge, it resolve the problem that the rom will not display wrong batt info
That's what i learned
As what Mr S says ... didn't see your post while i was writing mine

Factory reset resolved it

Pretty much lol. I mean theres no harm in it but its a waste of time because lithium ion/polymer batteries don't have a memory effect.
So pretty much after you flash a new rom, just use it as per normal. I've tried a lot of different scenarios over the past 3 or so years with battery calibration and roms and never noticed anything significant. Mostly placebo
Edit: with that said, if you feel more comfortable doing a calibration and you feel your battery is better. Just keep calibrating
For example: when I flash a rom, I still wipe dalvik cache out of habit even though devs have already said it gets wiped when you do a full wipe lol
