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

Bug on some devices where you have to reboot after reaching a full charge
Sent from my Nexus 7 using XDA Premium HD app

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?

Need help... I'm planning to buy Nexus 4

Can anyone post a screenshot on battery life with screen on ? I jus want to know how many hours screen on do u get on your nexus 4.. Right now, I'm using Galaxy nexus which has 3hour screen on time. I jus want to upgrade.! I don't care if the damn battery is too bad in nexus. But I prefer only nexus.. jus curious to know
Sent from my Galaxy Nexus using Tapatalk 2

This depends on many factors. But I get 4 hours with 3g all day, or 6 with wifi. But people say my phone is crippled so whatever

No screenshot handy but average 4-5 hours screen on time depending on WiFi/radio signal. T-Mobile U.S.

[Q] Horrible battery life

Why is my battery time so bad I only get about 3 hours of sot and about 16 of battery life... Is my nexus 4 defected or is it just my set up? I am using PA 3.56 with the kernel it comes with, how good is your battery life? And should I get an RMA?
Sent from my Nexus 4 using xda app-developers app

Flash Franco kernel milestone 2. I get 5 hours of screen on time.

3hrs sot is not bad for this phone.
Sent from my Nexus 4 using xda premium

SOT is really subject to usage. With a lot of gaming, you could see 2 hours or less. Also has a lot to do with your signal if you're not on Wifi. 3 hours isn't bad, and doesn't necessarily mean there's something wrong with your phone or ROM. I've personally never gotten much more than that.

Agreed. No need to RMA, need to get another phone
People with much longer times don't use it as a smartphone, believe me!
Also, we can see that your signal reception isn't good, and that for sure will hit the battery time hard!

Stock, rooted, Franco kernel

This is why people worry about getting 3 hours SOT. No demanding apps... Can't see network signal.

Nexus 4 battery

Hello, I just had a 3hr 30min SOT time with some fairly heavy usage (gaming) on my nexus 4. Is that considered good for the N4 and how could I improve it?

That's pretty normal I guess. I get about 4.5 hrs SOT with browsing, occasional gaming, messaging.. I think there are users getting a lot more than that!
You can try out different ROM+kernel combos to check out how your battery performs..

Nah, I rather not try them out. I like getting ota updates and hate factory resetting hehe. Any other ways to improve battery life without flashing anything or rooting?
Sent from my Nexus 4 using xda app-developers app

Turn off background programs.. Autoruns.. turn brightness down .
Still you are gaming on a phone. How long do you Toni the battery is going to last with your gpu and cpu running full bore?
Sent from my shiny new(bought last Nov), scratch less Nexus 4!

I can get 5 hours of on screen time during the work day. Using for browsing, txt, light calls. But during a weekend, 4 hours on screen time with heavy use of YouTube, gaming, and calls. I'm also running a custom rom and kernel. When I was stock I could not even get 3 hours of on screen time doing anything.

3.5 hours of SOT is good man. Especially if you were playing games and what not. I usually get the same in a 15 or so hour day. And your stock you say getting almost 4 hours of apt.. That's awesome man. ..
You can turn off a bunch of shat like GPS and BT and auto sync and blah .. But then what's the point of your smart phone..
Two things.. There are other threads about SOT that you could post this.. And don't let these "oh I get 5 hours of sot" guys get to you. Half of them are either lying about the sot or the usage their phone had that day.

Haha, good to hear that my sot is great. plus having all those kernels and Roms might mess up my phone so with stock this sot will be good enough for me. Anyways thanks for your information.

(4.4 with ART) How are your battery stats? Post pictures here with screen on time!

So i flashed my device and is now running 4.4 with ART enabled. Performance is definitely better but I want to get some extra juice out of it (considering that im 5h 6m at most with SCREEN ON TIME)
Share your experiences with pictures if you can please (with SOT)
Attached are battery stats from my previous Clean ROM with faux kernel just to give you an example

That's pretty weak battery life unless you were gaming most of the time

EDIT:
(referring to the pictures attached) Yeah. I was playing Asphalt, had wifi most of the time (even if there wasn't a hotspot), watched The Way Way Back via Mx player, Juice Cubes and was reflashing the ROM after having trouble with Xposed Framework patch.
PS. Sorry this was from my CLEAN ROM WITH FAUX KERNEL so what I'll post next is my latest Kitkat setup + stats

Not so pleased with these stats, but my Nexus 4 had record breaking stats! I have never had more than an hour of SOT, but today I got three! Running KitKat and ART.
Well, for my N7 it is a different story. Take a look.
That is the worst stats I've ever had. Let's give it a day, like I did on my N4.

Your kernel is at 69%. Either you switched to ART directly before this run or you have a rogue app that's not showing up in the stats. Reboot, recharge and try again.

Ok. That's probably the AOT compilation. Give it another boot without any new apps and you'll see more characteristic battery life.

My previous record was 1h 32m SOT on Android 4.3, while abroad.

No games. I don't do much gaming. Can play some rayman jungle run on my next charge.
Just one hour left til 3 days standby, already 8h screen on and 10% battery left. I'll reach 9h SOT without a doubt and on 4.3 I could only get that with one day standby. So standby time is the biggest improvement.
Sent from my Nexus 7 using Tapatalk 4

Auto brightness, mostly streaming and downloaded video, browsing, etc. 6 hours screen time takes me down to 45%. I don't often run it past there, but if I did, I should be able to get close to 11 hours screen time.

Wow, i used to think my nexus 7 had a decent battery time. Maybe i should try running on art and see if there's any difference.

Hey, here are my results after an normal Sunday with some gaming, web brosing and just normal stuff you do with your Tablet
