I've updated to 4.2 as soon as it came out, few apps didn't work but I soon noticed that it wasn't the issue.
The battery life on 4.2 seems to have drastically decreased for me. I was able to watch over 10 hours of video on maximum brightness with Wi-Fi and maximum volume, after update on MINIMUM brightness and half the volume I was able to pull off about 6 hours.
Did your battery life improve or gotten worse on 4.2?
Stand by time for me seems to have improved. No data to back that up, but I usually know where my battery is at anytime of day and it has been higher than usual since the update.

For me it seems to drain very fast, ever since the update AND I've got less apps since I did clean install. I kept same settings for Wi-Fi etc. Even Stand by seems to consume a lot more battery, I mean it drained 40% during the night. I wasn't downloading or anything.
Definitely worse. It even takes longer to charge.
The battery life after 4.2 update is awful.

I've just noticed that too. I was able to charge it overnight from scratch with extension cable fully. Now it goes just above 90%.

I updated to 4.2, and it drained my battery from 100% to 78% in 12 hours, with idle!!!
<<stock ROM, no-rooted, stock kernel, no installed apps>>
No difference for me. If anything it is better. Left my tablet idling after charge last night and it was still 100 percent when I woke up. On 4.1.2 it would generally go from 100 to 98 left overnight. Screen on time seems about the same.

You got big problem then. Wipe it might help
Definitely worse. Using it for ten minutes after a charge drains it by nearly ten percent, and this was after a full charge cycle. On conservative use it lasts me 6, maybe 7 hours, whereas on 4.1.2 with much more running at once I would ten hours easily. Its not that much, yeah, but I'm still going to downgrade. It's a good thing Google actually lets you downgrade unlike Apple.
for me battery life is much better. i get 17 hours with screen on 56% .
Mine has decrease a lot... now the back of my nexus 7 gets hot and drains the battery really fast.... anyone has a link to a better ROM or one that gives u a better battery life
?

man i follow my guide to update to 4.2 and i dont get any battery issues , if you wanna try http://forum.xda-developers.com/showthread.php?t=1990258
My battery is much improved. Before I was getting about 5 hours of screen on time with heavy use. After the update, I'm getting 7 hours of screen on time with heavy use.
Seems slightly better on stand by..that's for sure. Too soon to tell otherwise.

Hello,
After the update I noticed the tablet rebooting occasionally, so I flashed from scratch scrosler's 4.2 rom. The dev said is the official one, he just added root. I lost 25% in 7 hours of moderate use with auto brightness . Over the night battery remained at 100%.

After few battery cycles, I still have to keep my opinion of worse battery life sadly.
Just looking right now under battery settings, there seem to be many more "Google" things "Android OS (as it was before) Google Services, Android System, Tablet Idle, and Maps and Media server also seem to be taking up more battery.
Hey everyone,
Standby time is probably one of the most important features in a ROM/Kernel combination and its idle time is important to me.
This is due to the fact I work most days, until evening and by the time I get home, I have a couple of hours to kill.
Which is usually food, wash and chill.
On stock, I was averaging about 2 days, with 2.5% drain an hour, on standby.
I flashed PA 2.54 and Faux kernel and HOLYCRAP am I impressed,
0.8% drain an hour on idle.
Just out of curiosity, is this a good average?
Are their better kernels for battery time than Faux, as I was going to try Motley but Faux has impressed.
What do you guys aim for in Idle time?
Thanks,

Wifi off I can go 8+ hours and it still registers 100%. When my N7 is asleep, the battery usage graph is absolutely flat.
I haven't let it sit around for days at a time, but when I'm busy or doing other things, flat.

I'm using completely stock unrooted 4.2.1 and can say no, when it comes to standby battery there's basically no room for improvement. I don't have anything syncing in background (that's what my G'nex is for) and don't lose any battery during idle. I can leave it setting for several hours (as in more than 6) at a time and when I check it the most battery loss I've ever seen is 2%. And that's when the battery is below 50% already, if I start at 100 it won't move for 9+ hours of standby.

I have mine on airplane mode and i come back after work on a fully charged tablet and it's down to 82 percent.

Have to say the idle time is pretty stellar for me. I use the N7 for a monitor on my stedicam suit. Even with full day of monitoring once she goes to sleep I can almost anticipate 1% drop an hour.
Best settings are the airplane with 30% brightness.
When I'm rocking and rolling full brightness with monitoring HD through otg USB power is still reliable.

Hey Guys,
A bunch of people are complaining about the battery life on Nexus 4. I've been waited for a couple days since I got the device, to have enough confident about the battery before I make any post here. Yes, the phone battery drain pretty fast on the first few cycles. After a bunch more charges later, let me tell this, the battery life did get significantly better. It lasted about 10-15 hr depends on the load of the usage.
Here is my typical day, off the charge at 100% in the morning, listen to a few songs, checking emails, and messages while getting ready for school. About an 30mn to 1hr of internet browser and youtube videos while on the bus. By 1-2pm the battery drop the about 70-80%. I put the phone in silent mood til i'm done with all my classes. On the way back home on the bus, I listened to a bunch of music, web browsing, maybe a few phone calls, texts or games.
Compare to my old phone, Samsung Galaxy S2 T989, im impressed with the Nexus 4 battery life. My Galaxy S2 battery always die on the bus coming back home. What I'm trying to get at: if you're a light to medium user like me, then get this phone. I was hesitate at first because I always have bad experience with android battery life. But Google seem to get its OS right with this nexus device, mainly because the battery drain minimum while in sleeping mood.
Can you post your Nexus 4 battery performance screenshot if you have been using the phone for more than a few days ?
Is there supposed to be a question being asked? Or a statement as this is in the Q&A forum.
I agree with you on many points. People need to wait at least 5 to 7 days for the battery charge to fully kick in. The first days mean absolutely nothing as it is still being aligned plus the user is still installing apps and setting up their phone.
There are some notable problems in the default kernel that uses more battery Usage than normal too.

From full battery to this overnight + breakfast usage. Rasbean + Matr1x v3.0. Never seen anything like it. Coming from the GN, this phone is a different dimension altogether. On any aspect..
Had phone for 5 days. Drained phone to 10% then fully charged. Moderate to light use made it through a day.
Stock rooted + Franco Kernel.

Depends on how much screen time you got, which you didn't show us.
The trick is to be careful about using mobile data when signal is bad, I switch to WiFi when home to avoid unnecessary battery drain.

What is this obsession for battery life, it lasts me well through the day with moderate/heavy use. I charge it at night (if needed) and unless you are homeleless this shouldn`t be a problem. It`s a great phone and i enjoy using it.

I thought the same until my N4 actually arrived, it seems battery life is abysmal compared to my Optimus 2x which didnt have anything really spectacular in regards to battery size. On my O2x I could get 1.5 - 2.5 days depending on use, hitting atleast 1 .5 which was good and acceptable for me (I can charge at night anyways) however my N4 doesnt even reach 13 hours on similar usage!.
I am quite a light users of smartphones however I do like to have a power phone when it comes to using it on the basis of smoothness and capabilities if I need to say do work on my phone, I rarely play games though. Main usage is 2 email accounts on poll 1 hour steps, a third account that is an exchange server and polls in 30 minute steps and thats about it with some brief browsing and a handful of texts (been a quite time since I got my N4), this is less usage than my O2x and yet it still performs alot worse!
I was hoping of staying with stock as I was expecting it to finally be good, comparing it to LG stock attempts it is but battery life isnt . I will be trying the combo Vangelis13 mentioned, raspbean and matr1x kernel as that seems like a great mix however Parandroid has been on the table and it seems like alot of being are getting good results so I will try it soon .
If I can get more than a day of usage I would be really happy, if I was playing games or doing really heavy tasks I wouldnt expect it to last but right now it is doing pretty much nothing and dieing far to fast!.
One thing I've noticed since coming to N4 from S2 is that phone calls drain battery much more significantly on the N4. I could make an hour long call on my S2 and it would use no more than a couple of percent battery but the N4 used 15% for an hour long phone call the other night.
If I didn't own a nexus 4 and came to this thread to find out about it's battery life I would expect it to be good.
Point is you guys are misinforming everyone. The battery is mediocre and that's it.
It won't last a full day if you use it constantly and I do need two charges / day many times.
Let me put it this way, you will only get roughly 3 hours of screen time on stock everything. If that is good for you then it's will have good battery life, if not then you will say it's got poor battery life.

you are perfectly right.
I come from an iPhone 4s, which I changed because the battery life wasn´t that great and I thought it was time to try something new.
Got the N4 last friday and played around with it during the weekend.
Monday, tuesday and wednesday this week... none of these days I´ve been able to come back home with the phone still on.
I wake up at 7.30am and I usually am back home at 6pm.
In my opinion, and honestly should be in everyone´s opinion, 10 hours of battery life are unacceptable, whatever the usage is (considering that 7.30 of those 10 hours I was at work)
I have till friday this week to return it, which is a pity because the phone is great
i get 5-6 hours sot..
rom is omnirom 5.1.1 hellscore kernel b73.
100mv undervoltage hellsactive governer.
think 7 would be possible if google services would not take a quarter of the battery.
the screen is not taking that much battery as one would think.
think most issues with battery life come from fake original battery replacements.
had 3-4 sot using "original" battery. but after replacing with real genuine from official lg spare parts shop 5-6...

I think this will be a good general discussion:
Whats the battery performance like for you guys on a 2 year old phone, i know after a while the battery begins to degrade which is why im trying to see if this is the case for everyone :laugh:
Also what rom, kernel, tweaks are you using to get your current battery
1.5 years ago I easily get 6-7 hours screen on with power saving mode, for now i only get 4-5 hours with the same usage with Hurricane rom.
this phone is not two years old......
Yeah this phone is not 2 years old yet.. but aside, I love the Note 2 and don't plan on upgrading. I have 6 batteries for it, plus a external charger, so I never have to plug my phone in again. As far as UI goes, yes, it's missing some features, especially on 4.1.2 (luckily I never did the update ), but its multitasking features are kick-ass. At least for beginners. I had to tweak things to my liking, thanks to Xposed, such as default expanded notifications, Multiwindow for all apps, and such, but now that I have so much time into tweaking this phone I have no reason to upgrade.
I hardly noticed any difference between the time I purchased and now. My phone is 18 months old now.
Then again it could b me using 2 batteries and rotating the battery between uses so it doesn't degrade that fast.
But then again I'm not on stock rom. I was using miui in the past. Then regret upgrading to 4.3 which I found it too big of a hassle to downgrade to use miui again (4.1) and used hurricane rom with note3 mod installed. I tried ditto kitkat beta and rc1 but always reverted back to hurricane after a day of usage.

really guys only 6-7 hours? I go at least 10-12 hours, yeah of course it depends how much you use it for example when I use 3G and Wifi Hotspot simultaneously the battery drains like 1 second for 1%. I recommend you guys to install WakeLock Detector app. This app will tell you which app drain your battery, and guys, remove the facebook app as soon as possible it was on the top of the list.

Enough to let me go out of the house.....
When I first got mine it lasted about 2.5 days but rls8 and 9 of hyper drive combined with a certain game I don't get a full day.
I believe I have identified the source of MY excessive battery drain. It is Safestrap, specifically the use of more than one ROM slot. Yesterday, preparing the phone for sale, I deleted the two extra ROM slots I was using. Battery drain went down about 50% overnight (using stock slot(ONLY)).
How long have you had your phone? I've had mine for a little over a year, and the battery life on it has began to slowly degrade no matter what I do. I've always plugged my phone in at 20% or less, and if I could help it wouldn't leave it plugged in once charged completely.
Also, Before you go to sleep - Try clearing RAM and recent apps. I know it sounds silly, but it's helped my overnight drain quite abit.
You can only use stock rom slot or you will get very fast battery drain. With alliance build one I had 7 hours on screen time. AZ biker has a great thread in general section he easily has gotten 8 to 10 hours on screen time. Good luck.
