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.

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.

That gives you 4.5 hrs of use until it gets to 0%. So depending on what you are doing maybe that's actually OK. Post back once it hits 0% with the actual screen on time.

Referencing the Nexus 7 Guidebook, the claim is not 9 hours, but rather up to 8 hours of active use. As with any consumer electronics, that represents optimal conditions. Your screen brightness setting, what you,really doing, etc, are amongst the many variables that will affect battery drain. Having the screen on full bright is with white backgrounds is going to drain a battery exponentially faster than low brightness with darker images.

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.

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.

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!

My nexus 4 has horrible battery drain and gets INSANELY hot when I'm doing things like browsing and using twitter apps etc, It gets even hotter and droped about 1% every 40-50 seconds when playing a game Like GTA 3.
Never had such bad problems before. Is there a fix?

Sent from my Nexus 4
No, as I said, many people have had these problems, it does not come form apps installed.
the google stock kernel kind of swings between bad and good. i've had it go hot and munching away battery or stay cool and deliver 2 days on regular use. i would suggest you try a custom kernel like franco, that has kind of stabilized it for me and i can forget about the kernel again.
Hello guys i know thats my first thread in xda and that tread maybe looks noobish to you but i wanted to ask how is your Battery life with the OTA 4.3 update on nexus 4 i personaly installed
the update with fastboot and factory image as soon as it got realesed and until then i havent charged it yet.I ve seen some vids on yt surfed the
net and played some nfs most wanted by the way the battery status now is at 10% So how is yours ?
Was on OTA update til acouple minutes and from what I could tell, I felt my battery life last longer compared to stock 4.2.2 and slightly less than Franco's

That is outstanding. But how in the world is it possible that you have a "screen on" state without being awake?
I have been fighting battery issues for so long now, I'd really like to get to something as good as what you get...
i get 5 hours on heavy use until i hit 10 % well my setup is in my signature on light use i am sure i can stretch it to 6 hours with brightness on auto and wifi is on most of the time
battery life is never going to be better for me unless i uv. the previous setup, i used cm 10.1.2 stable with matr1x kernel. i uv and set the max cpu to 1350. it was really really good. i can use the phone from 8am to 9pm.
now currently using aosp 4.3, the default setup battery life has improved a bit compared to 4.2.2 stock, but after semaphore kernel installed and uv a bit, even with max cpu at default which is 1.5ghz, battery life has been really great.

Just out of curiosity, are in you the US/North America?
I had the same issue of losing tons of battery to the OS overnight. I reflashed to an older version of the modem. Most of the people I have seen so far with these symptoms have been in France and India. Must be something about the cell services and how they interact with the phone.
@Calebz: I'm in Ireland.
I've restarted the phone since and the battery usage is back to normal, will see for how long.
