last night i slept for around 8 hours, before i slept, i had battery power at 65% left, i wake up in the morning to find 27% left! now i think that verrryy much for idle state as my wifi, edge, games, calling/texting and screen were completely turned off for many hours. i look up the battery stats and found that Android OS had consumed 51%. below is the screenshot.

somebody please tell me why is that? and how do i get more life out of my battery?
Maybe your phone only goes up to 9 hours...
Maybe it's kernel related.. Are you on custom rom already?
My Droid on a JB ROM has the Android OS consume about 90% of the battery and it dies after 8 hours of screen off time, airplane mode. *shrugs* if anyone has a solution id like to know.

This has probably to do with something that is running in the background.
your phone apparently doesnt go into "deep sleep mode" Only in this mode you lose just few % per night.
I recommand to shut off your phone, take out the battery for a few seconds, put it back in, charge it in one go, then turn it on again. See what happens.
You can, of course, sleep with the charger in.
Welcome to Android, for the most part, our battery life sort of sucks :/

I've never had any problems with my Nexus S until my battery took a hit with 4.0.4 and now with 4.1.1 it's being a total pain in the ass.
For reasons I cannot figure out Exchange goes nuts. I turned sync off and didn't even check email yesterday but my battery had 10% left after 5 hours. With Gingerbread my screen was almost always the #1 battery user but since then others have taken away the crown. Exchange or Mediaserver with Android OS being runner up if not finishing first on occasion. I've been consciously trying to not use my phone for much because using it for much of anything means I'm down to like 3 hours on a charge. The phone never goes to sleep, the "Awake" bar is solid or a very intense bar code while the screen is more black space than anything by a large margin.
I am also finding that sms notifications aren't notifying me like they should be. Like I received a text 30 mins ago that I didn't know about until I went in and checked and seen one there waiting. Notifications are enabled. But I don't get the sound or the notification in the notification bar.
I flashed JB stock soju 4.1.1 (JRO03E) and I am having amazing battery life as you can see in the image with mild usage of 3 hrs 25 min screen on time. Usually with active use of browsing on 3G I reach 4 hrs screen on time.
I also don't have any problem with notifications.

Really didn't leave a whole lot of information for anybody to work with, for example I know theres a rom kicking around out there that would only update that battery in 20% increments. or Maybe it just felt like 5 minutes? or Maybe it wasn't as low as you thought? but sure wipe battery stats wont hurt nothing
Okay, now I'm a bit upset, I looked at my screen and it said "Charged" then I booted back into recovery and it went down to 98% and stayed there, I waited a good 5 minutes and still no 100%. So I went and wiped the Battery stats anyway - idk what to do.

Hi guys, I've flashed the 4.2.1 ROM by albinoman887 and only when the screen is on the lowest brightness it uses a lot of battery, really quickly.
Thread can be found here
When it's on standby the battery lasts for about 7 hours, but when it's on it lasts for around 45 minutes. Please help
I've tried
- Wiping battery stats
- Calibrating battery.

Your horrible cell signal is at least part of the problem. Your phone is constantly pinging the towers looking for a better connection. That's a serious battery hog.
You may have the wrong radio for your carrier. Or you may live in a dead zone for your carrier.
Also, is this your first battery cycle after a full wipe? I get results like that for the first discharge cycle after install. But then it becomes fantastic. Drain the battery all the way until the phone shuts off. Then charge it using a USB cord on your computer (not the standard power charger) for an hour past when it says 'full'. The slower USB charge can help to give it accurate voltage readings while charging so it doesn't stop charging too early. See if that helps.
The battery on Albino's 4.2.1 is pretty spectacular for most people, so the good news is that this is probably a fixable issue on your end.
The signal was when I'm out and about, most of the time I have 3-4 bars on HSDPA, I may do a full 24 hour charge or get a new battery
I have this problem too.But if i flash last build,baterry life is good.
I have been running CleanRom 3.0 for about 7 months now and have been getting great battery life. For the last week or so I have been getting horrible battery life and i cannot figure out why. I have not done anything different or added any apps since the fall. I have done all the tips and tricks to saving battery ....display set at 10%/30 seconds, All notifications turned off, gps off, bluetooth off etc... I can usually get an average of 22 hours before needing to look for a charger.
Today:
10.5 hours and 12% left. Not even 2 hours of screen time. I have phone forced on 3g and get good reception at my home where I was for most of the day.
Can someone please give me some insight here? maybe I'm missing something??

Maybe your battery itself.
There are far to many variables that play a part in battery life.
Look into 5.6 and remember to toggle off data and WiFi when not in use.
Worth a try.
Edit: now I clearly see you toggle WiFi and data off when not in use. Haha sorry.

Agreed, try changing kernel or kernel settings, gov types, speeds, tweak options.
Sometimes it take alot of trial and error to figure out the best rom/kernel combos. May also have to change a few things in the rom and/or kernel to do so. Goodluck!
You can try an app call "Better Battery Stats"

3000Ah battery lasts only 3 days with basically no usage. Also percentages don't add up.
What could be the cause? Any quality apps that can determine the cause?

and what seems to be the problem ? its fairly normal. you thought the battery will hold 3 months ? what cause ? well the wifi and mobile network. those also consume battery. turn on airplane mode and you will see 4 days.
I had phones with 2500mAh batter lasting almost 7 days with minimal usage.
Also app usage was: 12% + 5% + 3% + 2% + 2% + 1% + 1% = 26%
so something is sucking 74% of battery??
Turns out WiFi connections sucks the battery even if you're not downloading anything.
Android/Google battery usage calculation is just terrible.
