My Nexus 4 seems to be having a high number of wakelocks and battery life isn't what it used to be. Have attached some photos, anyone able to help me out and find the root cause of this.
Install BetterBatteryStats and see what that says about your wakelocks and sleep states etc.

Hello-
Ever since I updated to 4.2 and especially 4.2.1, battery life has not been the same. Today I went from 100% last night to 73% in 22 hours just in standby. I didn't change any settings that I can remember. Can anyone please help with this?
Thanks,
wws12

I had the same battery issues on 4.2 in standby...even with wifi disabled. I ended up flashing back to 4.1.2 and battery is back to normal. To me 4.1.2 is more stable and much smoother. Hopefully Google will fix these issues in the next update.

I noticed that a large portion of the battery is being used by something called "Media server" Any idea what that is or how to turn it off?

I'm also noticing the same sleep mode battery drain on 4.2.1,around 1% per hour..
I need to root my tablet to downgrade?

Use media scanner root from the play site and disable the media scanner. Then this battery drain should reduce.

Do I need to be rooted for this?

Yes. Root access is a must.

I think in my case most of the battery issues was from the device being new and the software stats still needed more time to be accurate, that has happened to me on my Sony tablet also..
Now I can see some real stats as I use better battery stats app for keeping track of the battery.
I use my tablet as a use when needed device because it's not my notifications device that is always connected, for that I use my smartphone. That said I turn on airplane mode when I'm not using it and sync when needed as well.
Só when my Nexus 7 is in sleep mode it has very few apps and services running other than the system ones.
So the stats I came up with are:
1% in sleep mode with airplane mode on and Google Now and Location History turned on..
And..
0.3% in sleep mode with airplane mode and Google Now plus Location History off..
So for me no Google Now as I don't need that much.. It lasts 3x more in standby without it... And the truth is, in my country Google now for me isn't that useful as it is although I'm sure someday will be..

It's strange...with stock 4.2.1 no root I haven't any battery drain... 0.7% /hour with wifi on and sync enabled...In the battery stats, even if in a hour i turn on the display on a minute, the display takes at least 40% of battery...
Hey all,
Using betterbatterystats I can see that my phone was awake for considerably longer than the screen. My question is...why? Is it a common Nexus 4 behavior? Is it that CPU wake bug people were talking about? I don't seem to have any odd wakelocks either. I am able to get around 4 hours of screen time if I try hard...or 3 hours with constant texting/what's app, and the occasional GTA vc
I attached pics, any help would be appreciated.

bump, anyone?
I am a new user and I like the nexus 4 a lot but the only one problem is the battery use up in a short period of time could any more help about the battery saving of this phone and share your experience and screen shot

Please use already existing thread for battery related issues;
http://forum.xda-developers.com/showthread.php?t=1992627
But yes you have to understand few things about battery and how to manage it. Install better battery stats or gsam battery monitor and CPU spy and learn to read the data they produce to identify what's causing battery drain and how you can manage it.

I was interested in how the battery on the Nexus 4 performed but i aint trawling through 242 pages.
No one seems willing to help on here you just either get thread locked thread already exists or go look at this already running thread, never known a forum like it.
How long have you owned your nexus 4? I was shocked at my battery life at first, but after about 2 weeks it significantly improved. Now I can easily last 12 hours with about 2,5h screen time. Not as impressive as some others, but still doable. So you might just want to give your device a few weeks to get used to you using it.

Anyone?

Almost 15 hours and you're still at 17%? You have nothing to worry about.
But if you are a worrier, just click the voice call line and it'll give you full details of usage. Just remember that screen shows relative battery drain, not absolute.

Install better battery stats, and inspect what your wakelocks are.
Thanks for the help guys. I decided to factory reset and try a new rom thanks anyway

Hey guys I am running the latest Paranoid Android with Francos latest kernel and my battery life is horrid.
If I get one hour of screen on time I am lucky. I am using custom color collaboration with the kernel and I am curious if this is playing a role.
Any advice would be greatly appreciated, thanks.

Colors on the Nexus 4 doesn't affect battery life.
Most likely it's your apps that are draining your battery life. Turn off services like Bluetooth and GPS and WiFi.
Install wake lock detector to see what apps are eating your battery juice. Low signal or bad service can affect battery life as well.

How's your reception? Bad signal is a huge factor

Try using Greenify. Might help a bit.
why dont you use an older kernel and see, r111 was the best kernel i got with battery life.
I had nothing but problems with Franco kernel. My phone wouldn't charge unless it was on AC for one.

Getting 3.5 to 4.5 hrs of sot on Franco and illusion, a lil more sot time if I'm on WiFi.
Apps sometimes play a big role in battery depletion as well as a horrible signal.

try using joker kernel if anything other than franco
I'm getting really sucky battery life on the MIUI 5 rom latest as of 2/7/13. Anyone else getting bad battery life on this? I've had a look at betterbatterystats and it's not really listing anything as keeping the phone awake. Went from 95% to 75% in 4 hours (I know that doesn't sound so bad but I wasn't doing anything with the phone, just had a couple of messengers on it - Trillian and Steam)
You need to figure out what is keeping your phone awake. On Franco kernel I have very little drain when just using messenger etc. I would think you have a rogue app or something causing issues.
