All stock, changed nothing at all, for me its best that way (for now)
[Samsung Galaxy Nexus] Dorilife:
Even though its just a Dev preview and to early to comment on this, I think its about the same on ICS if not better.

Completely stock , not even rooted.
[Samsung Galaxy Nexus] SeauxCrazy:
If you are getting bad battery life and wake issues, check your apps. I've heard LightFlow was causing wakelocks b/c it isn't optimzied for JB yet. I've deleted it until they can get it updated. So far, my battery life hasn't been great b/c I can't keep my hands off of it :)
[Samsung Galaxy Nexus] kmakiki:
Yeah, I would agree that battery life seems pretty good. It seems a little worse on Franco.kernel than stock, but hey, it's a new kernel and he is still trying to get all the kinks worked out. Also, no wakelocks on Light Flow, but I hope they update it soon, lots of my notifications stopped working.
[Samsung Galaxy Nexus] Anthonok:
Ehh I don't think its terrible at 2% an hour. Better than 10% an hour. I'll take a little drain for the beauty of JB

Sent from my JellyBelly Gnex
[Samsung Galaxy Nexus] anton2009:
IMO I think it's draining a little fast, but I think that's because I keep flashing kernels and add-ons which reboots and causes the battery to drain super fast... and I've been messing with apps a lot too. So I'm gonna give it another day or two for a definitive answer.
[Samsung Galaxy Nexus] ray3andrei:
How do i turn it off

[Samsung Galaxy Nexus] z06mike:
I don't understand what people expect??? They want to have an awesome huge screen, fast processor, 4G speeds, want to run apps like crazy and then have Google Now constantly updating and expect the battery to last all day?? People just need to be realistic!
[Samsung Galaxy Nexus] rasinell:
I'm completely stock and my battery is almost the same. Think it's a bit early to tell yet, we've all been playing more with the new rom ;)
[Samsung Galaxy Nexus] The_Stranger:
I am under the impression that the drain is slightly higher than on ICS, I am now 5,5 hours after charging, with 88% left (and a screen time of 18mins). On ICS I would be around 90 to 93% (with the 2000mAh battery). But nothing really to worry about.

Having said that, I did have lightflow installed and it did show in the wakelock screen, so I uninstalled that to see if the next charge gives me even better endurance.
[Samsung Galaxy Nexus] EP2008:
Except for the fact that the GN ranks as one of the worst superphones when it comes to battery life...

Just look at these performance charts:

http://blog.gsmarena.com/nokia-808-pureview-takes-part-in-our-battery-triathlon/#more-34312

Even phones with much more power have more battery life. The days of excuses are done.
[Samsung Galaxy Nexus] z06mike:
Those tests are done with basic apps installed, I guarantee it! Once you start adding facebook, twitter, linkedin, emails coming in, etc. etc., battery life goes down. You think it is coincidence that all of the "maximize battery guides" call for you to turn notifications off, fetch mail instead of push, turn brightness down, use wifi instead of 4g and so on??? Now on top of that throw Google Now in the mix, which is CONSTANTLY updating, and what do you expect!?

When I do a clean restore on my phone and have nothing on it, battery life is great! Once I started adding my apps back in the battery life starts going south.
[Samsung Galaxy Nexus] EP2008:
You're missing the point. All those phones were tested the same way with the stock apps and settings. They didn't give the GN a disadvantage by filling it with battery draining apps, they tested it stock.

Again, there aren't any excuses now for the poor battery life, since almost every other device offers better battery life - in some cases more than double!
[Samsung Galaxy Nexus] alec534:
I got 15 hours on, 3 hours screen on time yesterday...auto brightness, sync and Google Now enabled. Mostly Wi-Fi but some 4G.
[Samsung Galaxy Nexus] dextroz:
Thanks Dorilife - the rest of the folks sharing battery screenshots in this thread can learn a thing or two from you.

This is the way to provide battery screenshots: Overall screenshot, wake-up screenshot and the screen-on time. Without those data points claims and complaints are meaningless.
[Samsung Galaxy Nexus] harveydent:
Problem is the "almost every other devices that offer better battery life" have bigger batteries. The battery the GN comes with is a bit puny. Trying to compare a 3300mAh Razer Max and a 1820 mAh Galaxy Nexus is a bit silly, of course you'll get double battery life. You have twice the battery capacity.

Your "almost every other" qualifier is a bit misleading, because there are a ton of phones with even punier batteries and worse battery life.

Just get an extended battery. It's not that hard.
[Samsung Galaxy Nexus] :
Maybe you need to flash the JB radio and boot loader also? :-/
[Samsung Galaxy Nexus] svtfmook:
super phones? the only phone in that test i would consider owning is the lumia 900 or possibly the titan II if i had the gumption to try to stuff something that large into my pants (hey now).

nokia 808, seriously, you going to go to symbian?

razr maxx, super phone running 2 year old operating system with no hint of even ICS release from motorola? moto really duped their customers on the razr. all because they can't figure out how to shove their bloatware into the AOSP ICS rom.

lg nitro, pantech burst, i think enough was said there.

sony xperia p, ok, lets look at the past history of sony's xperia line. locked bootloader, poor mfg'er support/slow updates. good looking hardware, crappy bloatware.

so, again, the only phones i would consider to be "superphones" on that review are the 900 and titan ii. both of which run wp7, which it is a great OS (i have a focus s), it's just still in it's infancy and doesn't have the options that a "superphone" would have imo (ie turn by turn, where'd you go?). also, windows phones are single core, low ram, so they are not the super hardware you are making them out to be (even though wp7 operates superbly on single core).

as far as the gnex's battery, i think it's pretty much in range as every other smart phone i've ever owned. the only phone i have owned that had better battery was the focus s. besides, we have jelly bean when most other devices do not even have ICS yet. that IMO is worth the price of admission.
[Samsung Galaxy Nexus] EP2008:
Yeah, let's conveniently skip over the Galaxy s3 right? Come on, I enjoy the Galaxy Nexus, but let's stop making excuses for poor battery life.

The S3 is far superior than the GN in specs and Samsung fit a better battery in a similar sized phone. The battery life is much better on the s3.

Let's not forget the HTC One X, which also trumps the GN in specs and uses approximately the same battery capacity 1800mah vs. 1750mah), yet it gets far more browser and talk time than the GN.

I'm not ashamed to say my phones battery life is crap, and I certainly don't make excuses for it. I look forward to seeing what future devices can do to improve battery life.
[Samsung Galaxy Nexus] adrynalyne:
Grats on moving from 1st gen LTE to 2nd gen LTE hardware and keeping a straight face while comparing.

Could you possibly find a worse comparison? I mean, is anyone in the least surprised that new hardware is more efficient than older?
[Samsung Galaxy Nexus] EP2008:
Still making excuses? The fact remains that compared to other phones - 1st gen, 4th gen, LTE, quad-core, single core, ICS, Gingerbread, HD display, 8mp camera, 5mp camera, widgets running, wifi, no notifications... it doesn't matter... the GN is a poor performer!

I mean seriously, is there any phone that you would consider "fair" to compare against, or will there always be one thing that causes the 200% difference in battery life to be excused?
[Samsung Galaxy Nexus] adrynalyne:
Have you provided any phone worth comparing to?

I am not making excuses, I am saying you are skewing results. Want a fair comparison? Try a Droid Razr (non Maxx). Pretty similar battery life to the GN. Heck try a Rezound if you wish.

I found this without looking too hard:

http://www.droidforums.net/forum/ht...00337-battery-life-after-rooting-rezound.html

Sound familiar?

Battery life improves with technology. If you cannot understand that, well...not sure anything I say will make one iota of difference. If you want to compare, stay within the same OS and tech bracket.
[Samsung Galaxy Nexus] EP2008:
Are the Galaxy S3 and One X not worthy of comparison? I don't know what else you could compare with, since I'm not familiar with US devices, but to suggest that I'm "skewing results" when I'm merely pointing out what review sites have stated over and over, is a bit unfair.

When the GN first came out, the crappy battery life was because it had an HD display... now we have many phones with bigger and better displays which offer better battery life, so we know those excuses were just BS.

I'm confused... the Droid Razr and Rezound have superior battery life over the GN (5h vs 3h for web browsing on the Rezound vs GN), so I don't get your point. I think it proves what I'm saying: The GN has poor battery life.
[Samsung Galaxy Nexus] z06mike:
I do agree with you on that point. Overall, the is not the best performer in the battery department.
[Samsung Galaxy Nexus] babluc:
Turned off a couple of thing in Google Now and battery has improved after two days
[Samsung Galaxy Nexus] adrynalyne:
Bro, One X and S3 are from a new generation of hardware. No, they are not worthy of comparison, unless you are looking to see what new tech brings in the fields of performance and battery life.

http://www.pcworld.com/article/2433..._thin_and_fast_but_short_on_battery_life.html

http://www.pcworld.com/article/247234/htc_rezound_review_a_highperformance_android_phone.html

Sounds pretty damn similar to the GN to me.

Seriously.

You kept saying that the GN is the worst battery drainer ever, and then choose different generations of hardware to prove your point. Is the GS3 better on battery life? Sure. One X? Definitely. Are they in the same generation of hardware? Not even.
[Samsung Galaxy Nexus] svtfmook:
the s3 is a great device, sure, but it wasn't in that comparison review that was posted. not to mention that we (well me at least) get nexus devices for the vanilla experience. touchwiz is great and all, and the galaxy series are as close to vanilla as mfg overlays go, but, it's still not vanilla and it still has some bloat to it. as far as battery goes with the s3 vs the gnex, i'm not really sure on the s3's battery performance, but, to me, i would rather have strong support, than 3 days worth of battery life. i mean, i just charge every night no matter what device i have anyhow.
[Samsung Galaxy Nexus] BrianDigital:
mine has been just as good with ICS, though I did see pulse was eating battery for no reason(uninstalled and waiting for an update from them) but after eight hours in my lousy signal inside my place of work(always stuck on edge and sometimes no service at all), and an hour and a half of screen time left the building with 60% battery left. Will be alot better now that its the weekend and have signal wherever I go

to people have in issues with your phones battery check your service, and maybe back off the mods you use. This is clearly one way or the other and indivual users have an impact on how their battery performs or not performs
[Samsung Galaxy Nexus] lumberg:
Mine has been pretty bad but I've also been on it A LOT more than I usually am playing with new features and what not. So I'll give a few days of normal use before I can really compare.
[Samsung Galaxy Nexus] MilkPudding:
Mine is pretty much the same if not even better - getting 4 hours of screen time and still have more than 30% battery left.

And I use almost all cards in Google Now.
[Samsung Galaxy Nexus] killyouridols:
Thought mine was poor, until I realized setcpu was set at 1420Mhz min /max :p

Explains it....****! :rolleyes:
[Samsung Galaxy Nexus] EP2008:
My point is, you'll always have an excuse. If I compare it to older phones then you'll say they performed better because they were less powerful. When I compare it to newer phones, you say it's because they are newer tech...

Also, "After I spent 3 hours playing games, browsing the Web, and downloading apps over LTE, our fully charged test Rezound had only 30 percent of the battery remaining." 30% battery life left on an LTE device... this is far better than even the GSM Galaxy Nexus. What's your point? Most people get 3 hours at zero battery.

So, you can keep making excuses, but it doesn't change reality. I'm not trying to argue opinions here. These are all recorded facts and user experiences.

Believe me, I wish I could get 6 hour on screen time with my GN, but I accept that it's a pipe-dream.
[Samsung Galaxy Nexus] pfmiller:
At this stage? LOL, OTA is less then a month away. There may be a few minor fixes, but what you see now is pretty much what we'll be getting in 2-3 weeks.
[Samsung Galaxy Nexus] adrynalyne:
I am not interested in talking with someone who thinks the idea of discussion is to create a strawman.

I will move on and enjoy my Nexus.

Good day sir.
[Samsung Galaxy Nexus] rickbosch:
I've been getting 4hrs screen time for the past 3 days on JB, can't seem to put it down. Normally I don't use it more than 3 hrs per day.

I have all the cards on, auto sync is always on and I go to bed with 30% left on my battery. Having recently upgraded from a Nexus S, it's making me very happy.

Your battery should last a day, easily, if not, charge your phone. Simple really.

Also, if you want to stare at a phone screen for a quarter of a day, maybe you're doing life a little wrong, I feel an overwhelming sadness when I look at my battery stats and realize I've spent 4 hrs staring at the screen of a phone.
[Samsung Galaxy Nexus] zeke1988:
i cant get pass 2hrs of screen time with ICS, but with JB, it gave me nearly 3hrs. something must be wrong.
[Samsung Galaxy Nexus] patrickbartalesi22:
battery life should last a day mine decreases about 3% per hour using awesomes jelly belly rom v2.5 with stock kernel
[Samsung Galaxy Nexus] norazi:
yeah i noticed that the battery life is noticeably worse compared to ICS... not bad, but ICS was great.

i blame google now (refreshing all those cards) and project butter (60fps)
[Samsung Galaxy Nexus] NexusDro:
I'm running stock 4.0.4 and I found the battery life great, much better than my N1. Battery life of the Galaxy Nexus is not the most amazing, but I wouldn't say it is poor. It usually lasts a bit more than a day. Perhaps your poor battery performance is due to the low rf in your location?
[Samsung Galaxy Nexus] McDV:
How can you tell about battery-life, if you are using another kernel?! Please remember that the kernel is one of the most important parts of the OS. Changing the kernel will likely affect battery-life. So please, if you want to find out how battery performs on THIS JB-build, you should use this build as Google created it. ;)
[Samsung Galaxy Nexus] eberaldo:
so i just came here to tell...

...that my battery experience with jelly bean has been tremendous. the phone lasts so long and i think, it got even a little better than before.

after reading about those drains from a lot of people i'm happy that it just works.

apart from that, i don't even miss those AOSP things so much...
[Samsung Galaxy Nexus] buffalowolff:
Does anyone know what uses audioout_2 ? I believe phone sounds (ringing, dialpad...etc used to use audioout_3). I'm getting a lot of wakelocks from audioout_2 even when I'm in silent mode it seems.
[Samsung Galaxy Nexus] Arthur Hucksake:
Noticed that. Possibly down to system noise on touch.
[Samsung Galaxy Nexus] GldRush98:
>Run pre-release software

>***** when things don't go as normal

Okay.
[Samsung Galaxy Nexus] :
Good battery life

Im using the stock version no special kernels. It runs great with the extended battery.
[Samsung Galaxy Nexus] masterkamon842:
I got 12% percent drain in idle for 7 hours last night. That is really bad. I do have weather sinking, and Google now with all services for it active like location and such... still isn't all that bad for the features I'm getting. I know Google will make the ota much better though.
[Samsung Galaxy Nexus] EP2008:
That looks pretty dismal with an EXTENDED battery...
[Samsung Galaxy Nexus] iBustCh3rries:
most of those phones have a bigger battery and more efficient cpu than the Gnex.
[Samsung Galaxy Nexus] EP2008:
Even with an extended batter, the GN is a poor performer. We've run out of excuses. I wish JB would help, but it's made battery life 2-3x worse on idle.

You guys need to measure your consumption with an app, not just observation. That's the only accurate ay to tell what's going on.
[Samsung Galaxy Nexus] iBustCh3rries:
Well since you seem so unhappy with your phone you can give it too me and I will give you high five in return! :)
[Samsung Galaxy Nexus] EP2008:
I love my phone, but I expected more for $700... or at least what the manufacturer lists for battery life. My carrier gives a 15.6 day standby time... that's 0.27% consumption per hour. Does anyone get that kind of battery life? I get at best 2-3% per hour and I use a few standard features and no apps like facebook or twitter.
[Samsung Galaxy Nexus] live4nyy:
This is a pretty dismal statement considering you don't have any real information to base your opinion on. He never stated what widgets or apps he's using. There's no info on what sync options he has, how processor intensive the apps are. There are so many variables.

I also noticed you linked to charts of battery performance and then proceeded to label the GN as "one of the worst" when it actually finished middle of the pack in 2 out of 3 of those tests. And they're just tests, not real-world usage. You mentioned that the One X "trumps" the GN but I actually own both phones and have used them under the same conditions and the GN fares better in almost every aspect of battery life.

I'm not trying to argue here, because like you said, these are opinions, but at least base the opinions off of some tangible evidence and not standardized testing. Just look how well that has worked for our educational system. :p

I also have included some screenshots showing how well the battery held up when using it under normal circumstances (for my personal use).
[Samsung Galaxy Nexus] EP2008:
Sorry, I should have paraphrased what the reviewer said, so I wouldn't be flamed. The reviewer stated: "That’s tied second worst score we have seen so far, but as we told you, it wasn’t completely unexpected. "

Your results look fantastic. Is this stock? How do you get those screen times? It can't be from web browsing.
[Samsung Galaxy Nexus] live4nyy:
Yeah, you'll have to excuse me if all my "facts" are not in-line. I just saw this thread today and was trying to play catch up.

Yes, I'm running stock, and I'm using the 2000mAh extended battery though the standard battery was only marginally lower. And if you look closely you will see that Chrome Browser is the first app to show up on my battery use just below "Android OS" so I did use the browser quite a bit. I wish I would have checked the "time" for the browser but I didn't realize I would be using the screenshot to make a point. :laugh: I generally use the phone for web searching, emails, phone calls, texts, and random app browsing. Not much music or videos, but like I said, there are many variables and each person's needs will be met with different results.
[Samsung Galaxy Nexus] thepce:
I don't do heavy gaming or anything like that, but i do read my ebooks, make calls, text, surf, etc, with my phone. For background info, I would classify myself as your average smart phone user.

I'm running JB and i flashed the Franco Kernal to my Galaxy Nexus as of 2 days ago.... I still have not needed to recharge my phone since then.

I'm going on 2 days 3 hours since my previous charge, and I'm sitting 13% batt life.

I had an iPhone before and i was charging it every 15 hours, so No complaints here.

Franco is a pimp, Galaxy Nexus is a beast
[Samsung Galaxy Nexus] :
Dang 5hrs on screen time and 1 day total nice, are you using any specific kernels? As i looked at your battery charts i notice it increase a bit guess you had it plugged in for prob less than 1hr, im just assuming.

---------- Post added at 12:37 AM ---------- Previous post was at 12:27 AM ----------

I listened at least 1.5hr of music from home to work while riding the train.Did a b it of web browsing and 15mins of gaming, alot of texting, and light email. Im actually satisfied with 20hrs on my battery life.

One thing i notice is the On screen percentage on Jelly Bean is high 50-60%, on ICS i usually be around 30%-40% on screen. Guess when the final version of Jelly Bean is released next coming weeks, it will fix all the small issues.:D
[Samsung Galaxy Nexus] Moursy93:
well,on jb i am getting pretty good standby times,during sleep at night over about 8 to 9 hours it loses about 2 % maximum,sometimes even 1%,screen time though is between 3 to 4 hours max which i think is pretty gd,dnkno how this compares to ICS as i bought the fone the day Jb was leaked and directly flashed it :P
[Samsung Galaxy Nexus] live4nyy:
No, that is just straight discharge, unplugged the entire time. And it was more like a day and a half. ;)
[Samsung Galaxy Nexus] Nebucatnetzer:
It seems to vary very much between users.

I'm getting roughly 2h of screen on time with an extended battery. No idea why though. BBS doesn't show anything useful.

I tested the stock update and a light version with all the rubbish removed. The battery is getting better but not as much as it was on ICS.

I flashed the new bootloader and the new radio but didn't see any major difference.

I hope that the official release will fix it.
[Asus  Eee Pad Transformer Prime] jcoleridge:
Two weeks after the update, i can say that my prime is a worse than immediately after the update in wifi signal. Immediately after the update i used to have three bars in my kitchen (now 2) and two in my bedroom (now one, and there it is very very slow). Do you think that it is worth reinstalling the update from sd card or performing the other procedure (that i don't know exactly, but it is the one with the factory reset and the pinhole)?

Damn, wifi is the only problem on my C20 prime.
[Xoom General] TarKin:
Short questin,searched through the general and develpment forum but could not find any real usefull info:

that´s the standard setting, isn´t it? so just leave it that way and enjoy it :)
[Xperia Arc Q&A, Help & Troubleshooting] ImNineLIVES:
i really want to know this encase i dont brick my phone and having to go through a formal reset of resetting my phone when installing another custom ROM

i hope someone can answer this ASAP thanks

and what custom kernel is needed for cyanogenmod7.2
[Xperia Arc Q&A, Help & Troubleshooting] smartarse93:
There are plenty of threads about this, simply put: it's the software that controls the radio. If you want a better description search for one of the other threads.

And the custom rom will have the recommended baseband, if you already have it you won't need to reflash.

Sent from my LT18i
[Xperia Arc Q&A, Help & Troubleshooting] xtacy!:
The baseband is a subsystem of the phone that controls radio communications. It controls cellular hardware and communications with cell towers.

The FXP team bundles their kernel along with their CM releases. (It's the boot.img in the zip).
[Nexus Q General] ampharos:
The thing has good specs, good audio... and squandered potential. Only being a slave to a Android device?

This would have been a *****in' GTV device. As Google TV is in rough shape, even getting a full Android ROM would be good. Here's to hoping it can be easily hacked.
[Nexus Q General] joeymad:
Seeing as it is a Nexus device, I would surely hope that it has some level of hack-ability and modding. They even said that they encourage modding of the Nexus Q when they announced it at I/O. I'm excited to see where it goes!
