Battery issues after 4.2 OTA - Nexus 7 General

Is anybody else having battery issues after the 4.2 update. Mine is showing 52 for Android OS and about 11 for the screen. I'm finding time between charges a lot shorter.

On 4.2 with stock kernel, i'm getting 29% remaining on my N7 with 1D 2H 57mins since charged and 3H 56Mins Screen..

Yeah my battery life isn't great either. Android OS and Google services seem to be using more battery than before the update to 4.2.

Okay so its been 6.5 hrs on stock and still at 80% so I guess it may be certain apps

There was a note in the Moto forums that battery drain would be high after initial update. Should stabilize after a while.
I did the update last night and today im going on 9 hours and at 84% with 1:12 min of screen on time. This is significantly improved battery life over custom ROMs. This on a standard battery 1735mah, though its only a 2 month old battery. i wold normally go home with this type of use and time on battery and be around 55-60% battery. I did disable roughly 18-20 apps though and turned off all background data other then for Email and sync (once an hour) and weather sync once an hour as well.
This is what i was expecting as the ICS kernel i have read had an issue with 'suspend' and would keep trhe Android OS from deep sleeping properly
it's common for a fresh install to have a wonky battery until the OS settles in and the battery stats file populates properly.
Letting the phone drain completely, then either turning it off (or leaving it turned off if it shut itself down) while it charges up to 100% fully (leave it plugged it longer after it hits 100% to be sure) usually does the trick.
Its doing great now.

CM 10.1.3, battery emptying very quickly

I have been using my droid4 with the stock 4.0 system for half a year and was consistently getting about 12 hours of running time out of one charge with my usage pattern.
I have now moved to cm 10.1.3 as that is the version called "stable".
The battery life I am getting now is ridiculously bad. I have installed all my apps again and recreated my setup. With a similar usage pattern I am getting something like 5-6 hours at most. Just a short while ago the phone was fully charged. Charge dropped to 85% in about 40 minutes.
I have already done the calibration thing. Something is definitely discharging the battery like crazy as the phone is getting very hot all the time (which it didn't under the stock Rom.
So... What am I doing wrong?

[Q] [POLL] Battery Life on Stock LOLLIPOP

So Guys android 5.0 is here and i think most of u have tried it.So hows Battery performance on lollipop?
I feel it's worse TBH. I've tried several different roms and revisions and it still seems to be worse. Maybe I'm just playing with my phone more but my SOT can't seem to break 4 hours and it usually can't go all day on a charge.
Same. My battery life definitely seems worse.
I had better battery life on the developer Preview!!
this sucks
after removing Google Now and Google Fit, it has improved a bit, but still bad.
On some days it's pretty bad and on other days it isn't with pretty much the same setup... LOL
I accept the fact that battery has gotten worse with Lollipop, but I'm sure they'll fix this on the next release.
Chill~
Worse.
Developer Preview was significantly better than stick KK, final release the same as KK if not slightly worse. Was definitely expecting more from LP.
Sent from my Nexus 5 using XDA Premium HD app
mine is definitely way way way better
I'm a heavy user and its better than KK
I had the dev preview and Battery life was better than KK
Now on final release battery life is 1% drain per minute if I dont use the phone (but I discovered exchange services and gmail had updated from the one from the apk's I installed on the dev preview
re built again last night and max is 4 hours again without using the phone
2nd rebuld I did not restore anything
KK could be a day or 2 with using the phone before needing a charge

Ok, here is my xperia z3 compact not been charged for at least a day, has all the same apps and is used about the same as the Nexus 5 (z3 running kitkat, with NO power saving features enabled) and actually has a lot more apps running than Lollipop
and this is the Nexus 5 with only the apps you can see listed as running apps that was from a full charge overnight
It has dropped another 4% since taking that pic
In my case, the standby time of my N5 (which is new, I got it back from a RMA a month ago, so its battery isn't worn) is much worse on Lollipop than Kitkat: it drops 5% battery in one night in airplane mode, while 4.4.4 barely dropped 1%. On the other hand, the battery life when using the phone is way better! Before updating, I always got less than 4h SoT; now I get past 4.30 without even activating the battery saver.
So I'm not voting at the moment.
Mine is better than KitKat, some random drain's, quick soft reset fixes it.
Battery has definitely taken a hit wid L. Clean flash where
Mine's definitely better. I'm not a heavy user, but on KK I would need to charge during the day at work (usually afternoon time)...but now I can leave it till I get home.
I don't charge my N5 overnight, instead I wait to come in to work where I have a Qi charger on my desk. Usually I see it sitting at about 95% when I put it on the charger at work after leaving it alone all night. This morning I see it at 65%. I have never had it drop that low in one night before android 5 showed up.
What is even more interesting is that the battery stats claim that basically no one has been using any battery power. The highest number is 3% for wifi with 2% and 1% for a few other things, so where the heck did the 35% of the battery charge go?
I was in a similar situation as most people in this thread but currently I'm on my first discharge cycle on optipop rom with uber kernel and im on 4 hour screen on time with 20% to go.
I have google now off and location on and spent most of my time on wifi with avg cell signal.
I flashed the OTA manually and haven't done a factory reset, but the battery life is better than ever. 3 days and 9 hours, and 3.27 h screen on time. Brightness is set to auto.

Of course, if pay more games, I'll get it down much much faster.
I have some random battery drain issues too. But I think the issues belongs to 3rd party apps. In the safe mode there's not any battery drain. The 3rd party apps aren't compatible with Lollipop yet. So the main issue is this apps. Now 'Im trying to uninstall and reinstall the apps to find which apps drain the battery in deep sleep. I think which apps has a "cancel deep sleep mode" permission may drain battery if it's not updated for Lollipop. It's just a guess though.
First my battery life was really bad. I couldn't figure it out. I decided to do full wipe and it helped a lot. Now the battery life is better than on kitkat.

I'm getting worse battery life than any ROM stock or not I've run on the phone. I had better battery life on the dev previews. I don't think I've broken 3 hours screen on time or mixed usage(screen time+music time)once since the official image came out. I've done 2 or 3 clean flashes of the image and had also tried the Nexus 5 Experience ROM. I've used it each time rooted. Last night I did another clean flash of the image locked the bootloader and am going to try running it unrooted for a day or so with only 4 or 5 user apps installed. It shouldn't make a difference but I'm going to see what happens.

Battery life

So now that we've all had a chance to run 5.1 for a while, how do you guys compare the droid turbo battery life on lollipop vs kitkat?
I get better battery with KitKat. Maybe I just need to run it longer to break it in. I used to unplug my phone at 9 AM and plug it in at 11PM with 20% left and 4 hour screen. With lolipop, I had to plug it in now at 6PM with 30% battery and 2.5 SOT.

That's what I figured myself... I've been getting slightly worse battery with 5.1 but my friend swears he's been getting a better battery life on lollipop
I too get a slightly worse, or at least no slightest improvement of, battery life. Of course I have only unplugged the phone the first time after upgrading for a few hours so it is just my impression, but my usage pattern is just the same as I did yesterday.
Much better on Lollipop for me.

I'm getting slightly worse.
I'm gonna give it a week and if it doesn't get better I'm gonna try a factory reset.
My battery life is much better than it was on KK.

Only a day off use for me, but seems to be the same

5 hours 10 minutes screen on time at 18% battery.
I'm actually getting a lot better battery life. Im ending the day right now with around 60% and on KK I would typically be down to around 15% at this time. However I had particularly bad battery life on KK
About 3 1/2 hours on screen time and I'm at 34% battery. A bit of an improvement for me versus KitKat.

Battery life is horrible on LP. KK had better battery. what can we do?

Factory reset, and/or look at your battery drain. As posted by others we are getting better life post update, so it's not the LP itself that is causing the issue but something hanging on your phone causing it.
May I ask whether it is normal for Google Play Services to stay awake for nearly the entire period since unplugged? If not, what can I do before factory reset?

I've read that. Does the upgrading of 5.1.1 make any difference?
I haven't noticed any difference. The phone has stayed in the 20-30% range when i get home in the afternoon from work.
I'm getting worse battery and Google services is now the top battery user in my list.....
Google play services is the 4th on mine. Top of the list, right below screen, is Android OS. I find that as long as I disable apps I don't use my battery is pretty good. Unplugged it around 9am and I'm at 63%.

Mine feels a little worse.. But I've probably been using the phone more than before. It's like a new toy.

Stand by battery life

I am new with nexus devices just got brand new moto nexus 6 on black Friday and doesn't matter how i set it up it keeps using 2.5 % per hour on stand by , running stock 6.0 any suggestions, coming from note 3 overnight will drop around 2 ~3% total versus 24% nexus
In settings/battery, what is showing up? In other words, what process/app is consuming that battery life?
My N6 drops about 2% overnight (Marshmallow's Doze works beautifully).
Th3 use under battery stat looks normal, nothing to get my attention, is weird , got battery dr app. And it shows like 80 hrs of stand by in full battery but in reality more like 30 hrs, thank you for your reply, thinking on rooting, I am on sprint any suggestion on stable room?
