It could be for a number of reasons. For one, is 3g on a lot? Do you game? Read Twitter, Facebook or Google+? Live WP, ect. We need more details please.

Stock everything, rooted. Wifi model. Use it for web and 15 min of gaming daily.

Try flash franco kernel or flash other rom !

I agree with kilometers4. Better battery stats & cpu spy work well. I also suggest you download a battery calibration app. When I updated to Jelly Bean on my S3, the battery life sucked. But once I calibrated for a few cycles, it's great now. Same for my Nexus 7.

try switching to official CM10.1. Im getting 9hrs screen on time with it

I'm gonna hafta concur with this guy. However, I was having the same problem.
I used my keyboard to type into the search bar "bad battery life",
I looked at some similar titled threads and decided to look through this one
http://forum.xda-developers.com/showthread.php?t=1783390&page=3&highlight=nexus+7+not+charging
I followed the directions.
I did profit.
Next time use the search bar, and don't get butthurt when someone teases you a little. It's called the internet get used to it. And your a senior member you should know that.

When my nexus was brand new, i also had a few battery issues. But got it fixed after fully discharging the device a few times. Make sure it charges to 100% inbetween.

If you are running 4.2 i would reccomend you switch back to 4.1

Inverro route
Try to disable NFC

It has to be a rogue app, I'm getting way over that on my stock n7 32gb, stock 4.2.1

Are toy charging with the OEM charger. I know there is a deep sleep
Bug on some devices where you have to reboot after reaching a full charge

I find it kinda strange you only getting 3 hours out of it. On my Nexus 7 I can get little over 24 hours on a full charge. That's with basic web surfing, xda app, twitter and few YouTube videos.
Course if I do something more demanding like playing games I get less runtime on the battery.

I flashed Francis kernal and Cm10.1. Right now battery is 43% with 2 hours on screen time. So I format it and restore my apps using titanium backup?

Which one you got? Does it lag?
Swyped from another galaxy

i got the 16gb att version....it lags when on energy saver mode besides that its ok. The thing that upset me is half the storage is already used with all the stuff on the phone. It cam with about 8gb free. I am still playing around with it, the battery seems to drain quick but that's normal for a new cell out the box.

i do know it, i have been investigating about it without much success.
Mainly i can make it dissapear for half day if i use WIFI, once wifi is enabled the wake lock dissapears when i stop using wifi or do an experiment with it.
but somehow the error comes back once in a while, after a reboot, or after charging it.
no kernel fix it, no Rom fix it, im putting my hopes on CM

i removed fast dormancy and ril-fd is no more (im on crash rom atm where i found a cooked setting to turn off FD).

so this might be related to fast dormancy, i dont want to root this phone yet for certain reasons so i might try switching carriers, maybe it'll help

there are pre-rooted stock roms which are not supposed to increase the flash counter.
And i confirmed it, i toggled FD and the wakelockappeared, changed roms and tried that again, and the WL dissapeared.
But still my battery life sucks though, getting a honami when its out.

honami is the code name for the i1(naming confirmation pending from sony, will be disclosed at IFA or so we hope).
after A LOT of hate which went throught the phone, i updated the arrow rom to 5.1, deactivated FD, and nothing,i was getting 10% in 3 hours, for some reason i dont remember i rebooted the phone, and the darn phone still have the same charge from yesterday te phone have 24 hours of uptime (taking in account i have done some serious undervolt to the phone). i was getting about an hour per % an a half with hangouts and whatsapp freezed and in NO use or just checking the bat.
Not bad but too much work to have a "regulary updated" phone to work properly.
now i dont even know what will happen when i recharge the phone again what kind of behaivor will have this darn non-optimized phone I'll be reporting what happens.

I think that's the radio, and it might just be there because it has to be. Might also be other apps causing the radio to be active constantly, though.
Although I don't actually know anything about this (besides that RIL stands for Radio Interface Layer), so I'm probably wrong.

I'm having the same issue, and still can't figure out what's causing it. If you figured it out please report back.

Thats really weird, have you modified the kernel at all? you should try to reinstall the rom fresh.

Nothing modified or tweaking at all, Just complete stock kernel coming from Hyperdrive ROM and I still getting excellent battery life. Weird

Either your battery is faulty or the sensor doesnt read the values properly. Anyway do a factory reset and look what happens

Use a battery calibrate app as well. When you flash a new ROM its essential you wipe out previous battery stats.

Nah, you don't need any battery calibration. You don't need to wipe out any battery stats.

4.4.4 has really hurt my battery. I thought it was the battery, so I replaced with an OEM. Still drained, so I did factory reset, same problem, went with CM11 and it still drains fast. It even drains when the phone is powered off. I can charge to 100 and then power down the phone and 24 hours later power on and the battery is around 60%.

The Mahdi 2.7 with franco kernel is a great combination, I get almost more than 4hrs+ SOT on a full cycle charge every time.

I get 5 hours+ screen on time with a 2 years old phone, running CyanogenMod 11, RC 9, compiled by KcLKcL with -O3 patch, which gives the best performance as possible versus the power needed! Undervolted at about -100mV, aggresive two-core mode and HSPA network connected all day long!
