You can lower your brightness if it is not already at the lowest setting.

Unfortunately, the galaxy nexus has poor battery life. You could also try turning off data when you don't need it.

the screen is at lowest and it doesnt make sense turning of data if the problem is from screen right?

I'm having the exact same issue. Screen is totally eating up my battery life. It took 30 minutes for the battery to go down by like 10%. And the screen is 40% of the battery life issue.

Maybe I just don't use the screen as much as you, but I don't find this to be true for me. I find it has great battery life. I don't sit for hours with the screen on, but I do regularly text and check emails throughout the day, do a bit of web browsing, take some calls, and play some Angry Birds or other games in the evening. The screen is always at the top of the list for battery usage, but even on an extreme day I still have more than 30% battery left by the time I go to bed. I throw it on the charger and I'm ready to go again in the morning.
I disagree that the Galaxy Nexus has poor battery life, in general. I would argue that: all high-end phones have "poor" battery life because of all the things they do (especially 720p screens), your personal use of it consumes a lot of power and you could benefit from an extended battery, or you have a faulty device.

hi there, i do that exact same things with no games, so less usage but i get less than a day... i love the phone but the batery is just no working...

I don't understand why people don't get that when you have a screen that is 4.65'' it will destroy the battery life. My screen use is always at 60% or more but yet I still get good battery life. The screen is going to use the majority of your battery when compared to other things, that's just how it is.

sorry but thats not the point, when you pay 700 for a top phone, that is suposed to be the google experience to carry arround wiith you and you can only get 10 hours of battery time something went wrong in the process...

Most phones are $600 to $700, and name one 4g phone that will last more than 10 hours with moderate use and no extended battery, just not going to happen. You need to reset your expectations.

GN battery is giving lots of trouble, too. I picked up the phone from charge and it was 100% charged. ! hour of usage with 3g on. Usage includes 1 hours or music and reading of pdf books simultaniously and battery is dropped to 61%.

I think you should take a look at every other android phone that has come out with the same specs in the last year. Everything from the EVO 3d to the thunderbolt have their default battery's not last more than around 6-8 hours with constant use because of the screen & processors.
THis is why Verizon offered the extended batteries at a discounted rate right off the bat, because default batteries have never ever lasted that long in topof the line smartphones. FFS the new iphone 4s I've heard from a friend that their phones don't even last 24 hours.
I have a galaxy nexus, and mine has lasted... let me see.. one sec...1 day 3 hours and 25sec's with 35% left. (of course I have the extended battery) but here's the kicker: the extended battery has basically the same back as the regular phone does. so if they so desired, verizon could technically put out another extended battery just like all the rest of the phones, but they might not do that. I'm content with the battery life as it is almost identical as the droid X from which I came. The only difference is since I have a lot of un-updated apps for ice cream sandwich one of them is using "mediaserver" A LOT. I'm talking about that being the top of my battery draining with the screen being second. They both have taken ~20% with android OS itself taking 13, PlayerPro taking 13, and other random things like calls and txt msging taking ~10% each.
So I would suggest not trying to watch a lot of stuff on your phone while on battery, or don't expect your battery to survive long while watching stuff on that great screen

hymn thanks for the feedback so the only solution I see would be to go for a bigger battery. I'm from Portugal were could I buy one and whays the power?

If your screen usage is less than 50%, it be more worried about what else is killing your battery........

Still cant believe its draining battery life so quick.
300mb memory free and less than 10% cpu usage whole time.
official ATT ICS rooted. Nothing is running on background.
Anybody have extended battery? any review?

Looks like phone uses more power when hooked up to 500ma charger. My battery is draining with charging indcator. What's good battery app to checj my battery?

Sounds like something is wrong honestly. Did you do a factory reset after updating to ICS? Or did it come with ICS?

Something is definitely wrong if you're losing 30% charge sitting idle for two hours. When I had official ICS my phone wouldn't ever go to sleep and my my battery usage was terrible. No problems with Gingerbread, CM9, or CM10.

I have the extened battery the hyperion one and its lasts me like 48 hours i cant say enough of good stuff about it .

Hyperion battery, CM10, and Juice Defender make the phone worth having. I still carry a charger with me most everywhere I go, but at least I'm not frantically searching for a wall socket every 2 hours. The only down-side is that there are no cases for an extended battery; and as I found out, Zagg screen protectors most assuredly do not protect against drops.

Installed cm10 and played with it for while.
Battery is still messed up. I've been installing apps and surfing while plugged in and it charged only 3% in one hour.(1.2a ac adapter)
Does hyperion battery make phone too bulky?

On CM10, my phone drains about 1% an hour when just idling. I have Gmail push email and Google Talk running in the background as well.

If you're going to surf and all that, the battery will drain if you don't have the brightness down and possibly some way to throttle the CPU down. You are effectively using more energy than is being replenished.
It makes it about the same size as the phone with a stock battery inside the ballistic case without the silicon outside. But it's worth the money. Even on rooted GingerBread and the ICS leak I could still get right at a full day of moderate use from it.

I would agree something is causing a wake lock problem on your phone. Get better battery stats I think is free for being a forum member. It helped me find the offending app. In my case it was Whatsapp and more recently the update for power control widget. With AT&T official ICS I get 15 hours of light to medium use on the stock battery until I am at 50% and with the q-cell high caps city 15 hours of heavy use before it is at 50%. Under cm it was on about an hour longer before I hit 50%.

Also, if it's not getting a signal while in your locker, you will lose a lot of battery. I put my phone into airplane mode when I put it in my locker at work since it doesn't get signal in there. The other day I had it in my locker and forgot to put it in airplane mode, and I lost like 15% in 2 hours. I can put it in airplane mode and have it only drop 4% after like 6 hours.

Also, if you're like me and aren't in a 4G or LTE area, disable LTE and see a significant increase in battery life.

Hyperion gives me well over double usage. Well worth the money. Phone feels solid and not too thick. Try easy battery saver helps me a lot.

I bought the Q-Cell battery after getting sick of charging the phone twice a day (with stock GB). After updating to the official ICS my battery life dropped to MAYBE 18 hours with the extended. After a week of this I finally read about having to do a factory reset. IMMEDIATELY after doing the reset, I began to have serious battery issues with the Q-Cell. Phone would not charge up past 57% no matter how long it would charge. If the charger was unplugged, the phone immediately shut off. If the phone was off and you plugged it in, it turned on. Took me almost two weeks before I was back home where the original stock battery is/was. Popped it back in and the phone seems to be back to normal.
I find it bizarrely coincidental that at the exact moment I did the factory reset the battery begins malfunctioning. So, I don't know if something in the ICS code keeps it from playing nice with extended batteries in general, or the Q-Cell specifically, or the Android gods decided to smite me down for no reason whatsoever.
Now to see if the reset fixed the battery drain issues or if my stock LG battery drains completely in around 3 hours. :silly:
But back to the original question, the Q-Cell gave me two full days with moderately heavy usage. But beware doing a factory reset with it installed, JUST IN CASE.

check your baseband
check your baseband

To extend battery life, I turn off all the wireless components except phone, for daily use.
And this works effectively.

Improve your battery.

MY phone tooo.. I'm using a LG SU640 (which is korien version of this phone) Even with a 800Ma charger this phone drains battery when using 3g. for skype..
BUT I recomond you all to use CM10.1 with wind kernal 2.41 I've tried many many things and now I've managed to get 1day 12h battery life...
Really amazing. in idle it users about 1% for 3hours with 2G. you will not beleve even I didn't I was about to throw my phone away.:fingers-crossed::fingers-crossed:
Here is the link for wind kernal

Also this is a good guid http://forum.xda-developers.com/showthread.php?t=1781762

Bought a 3800mah battery - currently running pac-rom 10.2 nightlies. I am getting ~14 hr moderate use compared to stock battery which gets about ~8hrs. A wind kernel will definitely kick this time up.

I have the spectrum.(basically same phone. Takes the same battery) i got 2 extended batteries off amazon and on lg ics roms my charging rate is faster and battery life is longer after a few full charges

[Q] Battery life

Lately my Gnex's battery life has gotten pretty bad. Yesterday I had 25% battery left, while the screen-time was 2 hours and 30 minutes (it has been like this for a while now). I used to have at least 3,5 to 4,5 hours of screen-time on one charge. And, yes, I've tried to change ROM several times, with no effect. Maybe it would help to buy a new battery?
Thanks

That's actually decent battery life on this phone. Second of all. Screen on time doesn't really mean anything. It depends on what your doing with your phone i.e web browsing, Pandora streaming. both use data/wifi, but only one has the screen on the entire time during use. There's a great thread in the general section about how to improve battery life, but the best way, is by buying an extended battery. What I have done is simply bought a slim extended battery, and external battery charger, so I can switch batteries whenever my phone is about to die.

Try to use Trinity Kernel or Stock Kernel.

I think it could be the newest Google search update. I have a ton a screen off wakes and that's the only thing I can think of that's causing it.

CleanRom 5 battery

Hi,
This question is for anyone using the latest CleanRom on their Note II. Just wondering if your average battery drain is around 4-5%/h. I use BetteryBatteryStats. I also check the Battery section under Settings. The most battery life I have been able to get is 12 - 15 h with 1-2h screen time. At this point, the battery is at less than 10%. Is this normal ? I thought I remembered getting better life from older versions of CleanRom. I know these numbers are never achievable on any AOSP rom that I have tried. Just wanted to see what everyone's experience is with battery life. Just post any thoughts!
Thanks for your feedback! I appreciate your time!

Just like anyone else, it all depends on what kernel you're on and what apps you have wakelocking. I've been using Clean 5.0 as my daily for months and the battery life lasts me throughout the day until I need to sleep at which point I plug in... but sometimes, I'm running into fast battery drain due to some apps going nuts on me or when Bluetooth is trying to link from a long distance (where the phone would heat up and drain like mad... btw this only happened to me twice in many months). After a reboot, it usually clears up and after a recharge, I'm back to 14 hours with 20% left at night. I'm not one to be anal about my battery drain if it lasts me until I sleep (because I have NEVER had a smartphone that would last me that long without plugging in... in fact, barely half the day would be when my device would need to be fed).
I'm using Perseus' latest with a few screen tweaks, no CPU or power tweaks, using Facebook constantly, Pulse, SMS/MMS, camera throughout the day, Next 3D launcher with all the fun animations running, YouTube, Pandora when driving (so my Bluetooth is on constantly)... let's just say I'm a heavy user. When my kids get a hold of my device, they run a bunch of games and drain around 10% by the time I get it back.
I am happy with the battery life on my Clean Rom 5.0/Perseus Note II. I won't fuss about it as long as it lasts longer than half the day because that is what I was used before upgrading.

so, the battery drain is real...

I thought people were just exaggerating (i still have hope that i'm exaggerating) but man, i just got this phone and holy hell is the battery getting destroyed by "android os"
It won't even last a day with minimal/medium usage (some bluetooth and hotspot use here and there)
I'm coming from a galaxy s3 (which had better battery life).
I've tried installing a 5.1.1 rom but it seems to have no effect.
Has anyone figured out how to 'fix' this? Or can recommend a good rom (or kernel?) to get battery life representative of what i think a 3000 mah battery should be?
Thanks.

Greenify and the .97 OTA seems to provide decent battery life. Getting about 5 hours+ of SOT. Try using a separate app to see which apps are consuming the most battery and disable all the system apps you don't use.

I installed a barebones rom.
What concerns me is i had the same set up on my Galaxy S3 (5.1.1. lollipop with same apps), and the battery life on this zenfone has just been atrocious (leading me to believe 5.1.1 is not the problem, per se).
Am I wrong, did they not optimize this phone properly or something?

I do not have any issue with batery life. Mine last one day easy with medium to heavy use. Just do some charging cycles

I usually get a day with 4 to 6 hours SOT, without doing anything special to save battery

Do 3 drains to 1 % - you may find it stays longer during the lower 20% range so use a youtube film or sommat to blast it down,
then do a factory reset on the latest build.
Did this at the beginning when was only getting 10hrs max ugh !
Now easy 36hrs decent usage

I get a full days use (medium/heavy) with mine, not rooted not custom rom. I usually have about 20% left before it hits the charger. I have noticed small increases in battery life at every firmware update. I can't really complain, came from a Galaxy S5 and battery was about the same if not worst, but S5 had removeable battery. I've used a lot of smartphones and honestly, most will get your through the day and evening but that's about it, yeah, you might have some for the next day but most will through it on the charger by end of the night. My wife has the Iphone 4s and yeah, the battery lasts longer but the screen is almost half the size of mine, screen size makes a big dif.
