Are you using any VoIP app including groove IP? These apps require connection keep alive, which is reported in android os.

I keep groove ip on the entire time my nexus 4 is on and it never goes above 20% on android os. (Only when phone is idle, snaller when screen time is a good amount)

What do you recommend i do wipe and reinstall? i am on AOKP ROM everything was fine so i can't blame the ROM and it only started happening last night so do i need to remember what i changed maybe?

I'm at 40% battery on under 3 hours of battery 2 hours of screen time. But I've been playing games non stop. About to charge it for the 4th time in 2 days of having the phone.

I have Viber, Tango and Skype but I'm not signed into Skype. This screenshot is with mobile data turned off and me not touching the phone since it's been off charge about 3 hours, only lost 4% battery.

Install better battery stats to check if any weird wake locks are keeping your phone from deep sleeping. I am currently on minco v6 ROM with Franco r28. Fully charged last night at 11. Woke up at 6 and battery was at 5%.

Numerous background processes can play a role here. For example:

Auto update of apps (I set all mine to manual)
Live wallpapers
Various home screen widgets (weather and stock market tracking widgets, for example)
Auto email retrieval, especially Exchange server, especially multiple accounts

I have everything set to manual apart from 3 email accounts, no widgets or live wallpapers. Someone mentioned Android OS being top because the phone hasn't been used i think this is correct but what i was more concerned about was the battery losing about 30% in 5 hours without me touching the phone (screen off).

Really, install better battery stats and check the kernel wake locks and partial wake locks. One time my battery was draining really fast and I had suspend backoff kernel wake lock keep waking my phone up. Took a long time but realized my 5g WiFi connection at home caused that for some reason. After switching to reg WiFi, that wake lock was gone and my phone returned to deep sleep.

Coincidentally, my android os was also sky high on the battery list, although more than 20%. It was about 40% iirc

I think you have a faulty unit. Those numbers aren't horrible as sometimes the battery will drain faster for the furst15% or so. I would do a factory reset to see if you get the same results. If not then it's software. If you do I would call google for a replacement. Lots of people who got replacements had better results.

Is there anything in those screen shots that's keeping my phone awake? I thought this was quite good compare to a few days ago when i lost 30% in 5hrs with the phone untouched. Should it be better than this?

I think that looked pretty normal. Here's mine from today. Wasn't using it much. A short phone call and minimal usage.

Yeah... the android os isn't that big of a deal for much unless you don't use your phone like any

Android OS went down dramatically once I got rid of HD Widgets and Twitter apps. Android OS 6% of usage, 10 mins awake after 12 hours off the charger. 15% battery left at the end of the day, 2h 30mins screen time.

i just switched from iphone to my new nexus 4 and have the same issue in stand by - 88% battery drain over the first night (7h)! this sucks! i'll watch it and hope that google publish an update for that issue or i'll switch back to the (stupid) iphone 4s back again..
as a developer i have a lot of different IOS & android devices and one thing that i can say is that when talking about stand by times - no android gadget can compare to apple! a fully loaded iphone or ipad shows after 12h stand by 99% battery level..

I'm not sure why some people are having this issue other than the battery or device is faulty. My phone doesn't drain at all when my screen is off. Maybe 3% after 8 hours. I think that your issue is isolated and not the norm for this phone.
