Hey fellow GNex'ers!
I'm currently running CM10.2 on my Sprint GNex. I just pulled my phone off the charger, set it in my car, drove home from work (for lunch), then back to work. Once I got to work (hadn't even turned the screen on since I unplugged it), I checked the battery: 88%. Now, not even 70 minutes later it's reading 82%, a loss of 6% with no texts, no screen on, no notifications, and my 3g is 3 bars, which is pretty good for where I am (and the fact that there are no notifications / data usage).
Can anyone explain what it could be killing my battery? I'll post the betterbattstats screens later (when I get back out to my car), but for the rest of the afternoon I'm going to leave it there so I can get a better idea of what's killing the battery. I'm so sick of my battery draining when I'm not even touching it!
My wife's GNex did practically the same thing this morning. Her phone died in about 5 hours, but she turned the phone off about an hour after turning it on... She's running stock 4.1.2
Edit: Lost 2% in 11 minutes, so we'll round it up to 1% per 6 minutes right now...
do you not have LTE available in your area? if not, thats your problem.

I do have LTE in my area, but I've noticed LTE takes up even more power than 3g. However, my work is at an Army post, and since the towers aren't located on the post itself, it's kind of rare for me to have a solid LTE signal. I don't make any attempts to change the way Android decides which to use though, because I find that it's fairly intelligent about switching from LTE to 3g when LTE gets low, and vice-versa.

So these are images showing that I lost 30% battery while only using the screen for 12 minutes... That's just ridiculous!

Like many here I've been having battery drain issues since the day I purchased the Galaxy Nexus. I also purchased the extended battery since day one. I've been reading through every single forum on how to reduce the battery drain and none seems to have worked for me. I've tried switching to wifi, 3g only, no email push, no google+, etc and my phone at 100% battery would lose almost 30% within 2 hours idling. Then I was looking at the settings and I came across the Developer Options/Background process limit and limited my background process from Standard to At most limit to 1 process and my battery has improved tremendously. Prior to making the change the Android OS was using 80+ % on idle (Wifi or 3g didn't make a difference), now it's uses around 20 or less. On idle I'm seeing around 4% or less an hour vs 15% battery drain.
Please remember this may or may not solve YOUR battery drain, but it has definitely helped mine and I just wanted to share with the community on what else you can try.
I've had pretty good results with my battery. I think some of ya'll are either just playing around with it too much or have some energy-sucking apps out there.

Or that you don't have a connection to the data network.
Just say'n. (I do the same thing at night)
I had Wi-fi enabled for 12 hours, and the battery only dropped to around 85%. I have been on 4G for 5 hours now, and the battery is now down to 13%. I'm going to use a Wi-fi/3G combination tomorrow. Oh and I also have my phone rooted/underclocked to 900Mhz.

Light use with very little screen time from the looks.

I've been using it for 3 days and have had no issues. Anyways its as easy as checking the standard limit if you ever wanted to revert back.
So i picked up a Galaxy Nexus, was brand new (almost, package was opened but never used, checked the UPtime on the battery was only mins..) anyway. im and pretty certain it wasnt hacked or anything. it was just someone trying to sell their new free phone from a contract. model number i9250m
So i brought it to my GF's house, where i have never had any wifi issues, it would show normal good bars, connect and then get the IP.. internet would work fine, then all of a sudden, nothing.. turning Wifi on/off again, would sometimes allowe it to reset, but still, nothing more than 20 seconds... when i would use it in the bathroom (router is in the landlords on the other side of the wall.) it would work fine. No other devices in the house would give any issues over wifi...
SInce it was only 4.0.2 i though i would upgrade.. so i tried the nightly build cyanogen mod rom, cm-9-20120602-NIGHTLY-maguro-signed.zip still the same issue, even at my house, nothing, unless im 2 feet from the router.. 4-10 feet and a wall, no luck at all.
after some reasearch, they said change it to 5.0 ghz from 2.4, using one or the other didnt really change anything, (i think 5.0 didnt even work) i installed wifi analiser, here is what it is showing

with this reception, wifi only works from 4 feet. and is not that stable.. when it is connecting, it is super fast, but not consistant at all.
I have changed teh channel from 6 to 11, since wifi analizer said it was a better one..
I am using AWS (wind mobilicity) network. ANyone have any input or help?
thanks

i just replaced my new gnex for the very reason you stated. the phone also got very warm while charging and took grainy pictures.
so far the replacement is doing all 3 things much better.
i would suggest trying to get a replacement.
the funniest thing, i have 2 boxes (internet with built in router) and a seperate linksys, (used as a switch) i just disabled wif on the switch and everything works! that doesn really explain the problem at my g/fs house,
this was weird, because i was hacing the same issue with my Nexus S and an Ipad.. hopefully i dont have a faulty Wifi.. thanks for the help..
That's weird. You have super strong signal. I don't know why it isn't working. Haven't seen many posts about this issue.
I'm new to the Verizon Galaxy Nexus (Toro), I just switched from a Thunderbolt.
So here's the issue: I am seeing much quicker battery drain than I would expect when running Carbon 1.1 (Android 4.2.2) or Carbon 1.0 (4.2.1). I'm going to try franco kernel today. Here are some screens showing stats. I replaced the stock battery (person who sold it said it wasn't holding charge) with Anker battery. I also disabled NFC wondering if maybe this battery doesn't support it.

Any advice would be greatly appreciated, maybe I missed something with installing the rom with this phone, as I said before, I am new to the Nexus.
You might can squeeze a little more, but </= 2 hours screen on time is generally what you can expect.
Seems pretty normal to me. With almost an hour of onscreen time 53% after almost 7 hours is pretty good.
Alright, thanks for the input. Sort of not what I expected, as this isn't much better battery life than my TB. Would anyone expect an improvement using just 3G? I don't typically use data on my phone anyone, as at home and at work I have wifi

Not a substantial one, no, but minimal improvement maybe.
EDIT: Unless the majority of your battery drain is coming from data usage.. Torrenting and such..
I somehow noticed a much better battery life in 4.2.2 than 4.2.1
I am running ParanoidAndroid 15th Feb release and AK 691 Pirates on my maguro.
I have disabled sync and only sync mails 2-3 times a day and complete sync once.
And screen on time between 2.5 to 3hrs is normal for the GNex.
Hi everybody,
i'm running on Paranoid 3.6 und AK256 Kernel, and these are my battery stats.
Used the phone alot during the lectures today, tested this halo stuff (really don't like it).
But ~9h is just too little or?
System is just 2 weeks old, so pretty clean i think.

What's your on-screen time?
Sent from my Cyanogen-flavoured, AK-powered Galaxy Nexus
It was about 2.5 hours screen on time.
My stats for today are attached.
Screen on time is 3h 5min. The almost horizontal line at the beginning is in airplane mode but with wifi on.
Is this okay? It feels like that this is way too little runtime :/
Thanks a lot !
seems fine to me.
That's about average battery life for me. If I stand right in front of the wifi router + good 3G signal I can maybe get 3.5-4 hours screen on time. Else its usually about 3 hours on full wifi. Or 1-2.5 hours on full 3G or mix of 3g/wifi depending on the day and the brightness.
3hrs is my normal. Just go out n buy a separate charger and another battery or two (that's what I did) and u just have an extra battery on hand when u need it

Do I need a new battery?
Hi guys it's me again,
NOW I think my battery drains way too fast, I don't use my phone that often but I can't make it over one day!
Here are some screens, i know i've got 30 % left, but thats gone pretty soon
I'm running on Purity 5.7.1 (Android 4.2.2) and Fancy Kernel r36 extended version for quite a long time now.
Is my battery too old and damaged, should i purchase a new one?
Big thanks for any help !
Yeah, it's normal.
You're last longer then I do

Hi guys
I've had my HTC 10 for over 2 weeks now, and as I decided to change from iOS to Android the first few days/week the battery would only last me barely 14 hours.
However, the last few days were very impressive with the phone lasting me 2 days and 12 hours with normal usage (no games and not heavy internet browsing).
But today something weird happened as I took the phone in the morning to go to work and at 10:30/11:00 my phone was down to about 60% without me doing anything to it and without a specific reason to it.
I will attach some screenshots to see if anyone had the same problem/issue.
I would appreciate any feedback you may have!

Did you try to restart the phone? Something is keeping your phone awake. A restart every couple of days is always helpful.
Yes, I did.
However, the phone's battery still only lasted until 7 pm. Which is really weird as I literally almost didn't use it...
Will see how it goes today
My battery life did not last very well either when K first got my 10. I'm an HTC lover by the way. In my experience, I've learned you really need to optimize the controls and settings after you purchase the phone to get the most out of your battery. I restrict a lot of app permissions that ask for location so my phone isn't constantly locating itself on GPS. Same for Wi-Fi. I turned off the auto scan for the Wi-Fi cause that absolutely toasts your battery. And then I turn off vibration feedback for touching keys just to conserve even more. I moderately use my phone throughout the day checking mail, texting, browsing the web, facebook, xda, altos adventures, a YouTube video here and there. I get to my office at 4 in the morning, don't get home til 3 pm and my phone still has anywhere from 45 - 60% charge. I think that's great considering my M8 normally has 15 - 20% when I would get home. Just tinker with the controls for a bit. Maybe I'm wrong but this is what worked for me
Yes, I understand and I have done so by restricting must apps and by having the same constant brightness and normally (as it happens today) the phone after 12 hours still has 50% battery. But it was that episode that literally was eating away the battery without me using the phone at all!
Thanks for the replies so far
