My two Brothers just picked up the unlocked GSM Nexus off the Play/Market store last week. One has it running on pre-paid T-Mobile, the other on Straight Talk ATT, and their battery life is ****ing unbelievably better than what three of us get on the Verizon Nexus, and we are not using 4G/LTE at all.
Both my Brothers use their phone at work, no Wifi just the 3G signal, and they both text me this week telling me battery life %. Right now after 4+ hours unplugged they both around 85%-90%, not using it except sending several texts and reading websites. And after a work day unplugged for like 10 hours they both have like 70%-75% left.
Now myself, my Wife and buddy have the Verizon Nexus, my Wife barely uses her phone at all, and at lunch time will be at like 70% battery left, and after getting home still unplugged for 10+ hours she's at like 45%. Where my Brothers with same use would be at 70%.
My buddy has the same as my Wife's usage, no WiFi wither, not using phone much and his phone is at like 40% after 12 hours or so. Both of them have 4G/LTE off and GPS off, and no sync on.
I use my phone a lot for work sales calls, and I am in the red by like 4:00pm, I get maybe 7 - 9 hours of use on a busy workday.
My Brother on the GSM T-Mobile, said after 23 hours his phone was at 45% battery life, and that was him using it quite a bit, dozens and dozens of texts, lots of websurfing, tons of e-mails. Our Verizon Nexus would never get that kind of battery life.
It is known. What really matters though is screen on time.

I agree screen time is crucial. But my Wife uses her Verizon Nexus very little at work and by time she comes home is at like 45% battery after about 12 hours or so. My Brother on GSM Nexus after 12 hours and using it a bit more would be at 70% battery.
That is a HUGE difference in battery life with very similar use.

do they work in the same building?
if your wife works in a place with not as good of a signal, i expect her battery to drain faster as the phone is trying to get more signal.
I installed AOKP 5 on her phone last night. Her battery seems much better. Unplugged for 7 hours at 80% battery now. That is a major upgrade. But again she barely uses her phone at all during work, pretty much just sits there. Where my Brother with same use today is at 90%.
I am running CM9, unplugged for 6 hours at 35% battery, but I use my phone a lot during work. Have 2.5 hours screen time. Tons of texts...lots emails...several phone calls....web surfing.

With GSM you can expect around 3 hours screen time and tons of standby time.
The standby time is great, but the screen time is somewhat mediocre to me.
Some days my battery just gets ate and others (like today) I'm having good battery. Usually I'm finding that apps are open in the background even after I hit back to "close" them. So if I keep up on the "Recents" menu and swipe it all away, I see an improvement.
I'm waiting for the MIUI styled "X" that closes ALL recent apps in one strike. Every little bit helps. An older version of Gummy (x.8) I had insane battery life. From 8am-3pm I would still have like 75%. I'm running LiquidSmooth right now and at 3pm I am at 60%. This was with 40 emails and 2 20min calls. No texting today
But LiquidSmooth has more options and is much faster then Gummy, so IMO the small battery difference is a good trade off. Later Gummy versions seems to consume more battery while lacking in the features.
AOKP never ran well for me in either the performance or battery department. Seemed to be laggy AND battery lousy. However I haven't played with it in a few weeks.
I too keep 4G disabled but I also have WiFi on all day (I never turn it off). I also use "Bluetooth On Call" which enables my bluetooth while on a call, so I can use a wireless headset. It automatically disables bluetooth, but I'm sure it consumes more battery then a normal call.
I only have 40minutes of screen ON time too. Mostly quick checks of emails. A few turns of WordFued and DrawSomething. I do work in a dungeon with little/no signal, which I suspect eats it up.

But it depends what you do in that screen time. If you do a lot of gaming and browsing with 3 hours it's great. If you just swipe through the home screen and send a couple text message with 6 hours of screen time, not so great.
A cool test would be to turn on airplane mode and play a movie. I'd be interested to see if it has something to do with programming vs hardware.
Then the same test with 3G.
Both really need to be setup similarly, same wallpaper, apps, etc, to really get a good measure of comparison
This isn't a news flash. Its been pretty well known.

Well, yes and no. Gaming does use more cpu and such than just flipping through your home screens so I see where your coming from and agree to an extent.. But also consider that display is almost always the biggest battery consumer in battery stats, regardless of what you are using it for.
If you switch the 4G off then it will be a different story.

If you really want to compare the battery on all those phones, at the end of the day have your wife, your buddy, your brothers, etc...send you a screen shot of their battery stats. There are so many reasons why your battery life can change, and unless you are following someone all day then you really won't know the full picture.
And yes I usually say screen on time is a better "quick" comparison of battery life. Someone who has a display timeout of 1 min compared to someone with 5 min will have significantly different battery results, even with similar usage.
LTE is a *****.

CDMA radio technology is a bit worse on battery than GSM, I'm betting that's where most of the difference comes from (LTE excluded obviously). With my screen on constantly, I've gone over 5.5 hours of screen on time before on my VZW GNex with about 50% 3G/50% WIFI usage. Again though, that was almost constant screen on from 100% to 0% battery. I've also watched the entirety of LOTR: Return of the King Extended Cut (4:20 minute run time) with my phone while also having 2 or so hours of standby on one charge, but I was in airplane mode for the majority of the movie watching. The screen is absolutely the worst battery killer by leaps and bounds and that will hold true no matter the variant.

True, it always is the biggest battery consumer as anything you do on the phone requires the screen to be on. But it also depends on what kind of users we are. If you use your phone mainly for calling and texting and emails, then 4+ hours of screen time with a total of 16 hours should be good and doable. But if you do a lot of gaming, browsing web, tasks that are heavy then 3hours+ on screen time with a total of 10-12 hours on the chart is pretty good I think.
I agree with a previous poster, screen on time is all that matters. That's why I got an ugly humpbacked Trexcell 3800 battery. Now I get 5 1/2 hours of screen on time on my Verizon GNex. Great when compared to my old time of about 2 hours.

None of us on the Verizon Nexus have 4G on. We all leave LTE off.
So why is the GSM version getting substantially better battery life ? Seems to be at least a 25% difference, if not 1/3rd better battery life on the GSM Nexus.

See my post above. CDMA radios are slightly worse on battery than GSM radios.
Like I said, I've seen 5.5 hours of screen on before once and 4+ many many times. I highly doubt the difference in battery between my VZW Nexus and a GSM Nexus under constant use from 100% charge would be more than +/-5% in either direction so the difference is somewhere in the standby times of the two devices ie. GSM vs. CDMA radio.
I've had my Verizon Galaxy Nexus since launch day. I've NEVER been able to get more than 3.5 hours of screen-on time with this thing. But lately it's been even worse. I'm seeing anywhere from an hour to two hours before I have to reach for a charger, usually right around 1.5 hours of screen-on time. It will sleep for a good long while (no wakelocks causing drain that I've found).
I keep sync on for some Google services, like Gmail, but not many. Battery life doesn't really seem to change regardless of using 3G or LTE, nor does wifi seem to improve. When the phone is awake, and the screen is on, the battery just drops like a rock. Literally every time I look at the battery percentage in the status bar, it's dropped another 1-2%, even if I'm not doing anything.
I've run everything from stock 4.0.2 to AOKP JB nightlies (which I'm currently running, with imo's kernel). I've tried practically every ROM/kernel combo out there and never seen an improvement. I've undervolted, underclocked, played with brightness settings, everything I can think of. It's been wiped, the battery has been occasionally cycled, etc, and nothing seems to improve the battery life--it's only gotten worse over time. I did, at one point, have an OEM extended battery, but it wasn't a significant improvement enough for me to get over losing "the hump" so I got rid of it (actually traded it for a Droid X, lol).
So I'm kind of at a loss with this thing. Does the battery really suck this much? The other day, a coworker with a Galaxy S III on Sprint used his phone for over 3 hours of screen-on time (I looked at his battery stats) leaving him at about 35% battery. Mine was also at 35%, with only 1 hour of screen on time. I understand the GS3 gets better battery life in general, but this is getting to the point of being unacceptable.
Not unusual. Big screen = big power requirement. Poor reception (i.e. bad coverage area) saps the battery the quickest, extended screen time on is a close second. Have you tried the extended battery? It adds enough to get well through a work day and commutes if you're not using the phone as a laptop. However if the phone is being used as a laptop, I'd suggest buying an actual laptop, or better yet a tablet. I get 10 hours of steady use out of my Xoom.

The phone doesn't have amazing battery life but what you're describing sounds pretty abnormal. It may be a bad battery.
Yeah seeing as the battery is around 9 months old, I would first try and get another battery and see if that makes a difference. Most batteries dont go bad that quickly but wouldnt be surprised if it did. Worst case you would have an extra battery that you can also keep fully charged as it seems though you have tried most everything you could regarding any software issue.
I've seen so many threads here and at The Verge that I just don't understand. I've been using Android devices now for about two years and I've NEVER had a problem with battery life being worse than my iPhones. I have a 3GS and the battery on it dies after about 8-10 hours of moderate use. Meanwhile, I'm at 12 hours on my SGS3 and 50% battery. I also have quite a lot of applications running in the background. Granted, today I have been low usage, but yesterday I was on the phone for hours and I still went 12 hours before the battery icon turned yellow. I haven't HAD to recharge before 12 hours for ages, even my Atrix went longer than that. I even have a screenshot from a few days ago where I went 14 hours and only dropped to 63%.
Are people just nuts or what is going on here?
People expect to play games at max brightness for hours and still get 12 hours battery life.
In with you, I use my phone constantly through out the day, I run my business from my phone, and routinely get 14+ hours per charge no problem. I just made a few tweaks, nothing big, and I'm good to go. This phone lasts noticeably longer than all my previous iPhones 3,3g and 4. Plus it charges twice as fast as those and never over heats... all my iPhones would get so hot that I couldn't charge them in the car with out testing then in an ac vent, and that's just from half an hour to an hour of talking... sgs3, I can talk for hours with no overheating, and it charges like a boss.

Before I flashed Cyanogenmod on my S3, I rarely reached over 10 hours of battery use with data on.
Neither one of my galaxy phones overheated to where they shut off until one decided it was dirty and jumped in the washer(rip 1st sgs2) .
I had changed my iPhone 4 back glass to one of those metal backs. Now when its on charge it will almost burn your hand if ur holding it. And I have had it shut off while on Facebook. Battery never last very long on I phones if the brightness is up data going WiFi seeking and jbing.

My battery life is great! Much better than any other phone I've owned...12 hours of use for me is nothing....I get 18+ without a problem....frequently I've gone well over 24 hours.

I think some phones came with defective batteries. I'm running juice defender and could easily make it through a 16 hour day. 3-4 hours of screen time was not uncommon. 3 months later, and I can barely get 10 hours of use and 1.5 hours of screen time. Time to get a new battery!

I am not sure what is going on. I don't have the best battery life I can get 10 to 12 hours moderate use. Steaming music, reading rss feeds, checking email, 2 to 3 hours screen on. I would easily last a day on my iPhone 4. I have juice defender, lowest screen setting, custom kernel with under volting. I think it has something to do with my area. Att is so congested in my area I am barely able to use data sometimes. It's better with lte but still an issue at times.

People use their phones differently. Just saying.
If I don't turn the screen on, with LTE data, my phone dies in 9 hours (I tested it). And this doesn't mean there's a problem with it. I have around 15 different push notification apps running in the background, all of which are using data almost continuously. I don't think I can expect it to last much longer. And if I know I'm not going to be near a power source for longer than that, I simply turn off syncing to get better battery life.
To me, it looks like the LTE radio is the biggest battery hog. Let's see if the iPhone 5 can somehow get around this problem so that other manufacturers can take note

I was going to mention this. I noticed a significant improvement in battery life once I used JuiceDefender to turn off data while my screen is off. 4G LTE is the main culprit of most of the complaints for battery life (in addition to brightness). That is going to be a big problem for the new iphone if they can't get the battery management for 4G correct. It has taken Samsung a couple of years to get the battery working decent with 4G. I have my doubts that Apple could top them the first year running LTE on the iphone. Who knows, maybe that will be the "new" feature they have been working on over the year, LTE power management. That's the direction Motorola has headed in their new RAZOR MAXX devices. We'll see, either way, the consumer comes out on top as we have more competition to drive down prices and receive better products each year.
Best battery life for SGS3
With AMOLED and Android u gotta take special measures to get good battery life:
- kill bloatware. NostalgiaTurboSlim script will help. Or freeze unneeded apps - like Maps and enable them only when needed.
- disable various notifications - Play Market, WiFi etc
- disable ads - root and download AdAway app - they steal your mobile traffic, battery life and make you blind!
- put dark nonLive Wallpaper
- remove any widgets you don't use. I just removed all of them.
- disable animations and transitions
- disable haptic feedback
- disable touch tones/sounds/vibrations
- try using nonAuto brightness (I gave up on that - sunlight does not allow me to change anything manually)
- disable autorotation
- use dark Opera browser user.css
- use inverted or dark themed apps and Gapps, there is dark MMS, Twitter and Facebook in my ROM
- downclock CPU to 1GHz, or enable PowerSave On.
- use modern KToonsez kernel with PegasusQ governor, it downclocks CPU during screen off
- use CPU1 disabler script if your ROM/kernel supports it
- keep chargers around you, buy them at amazon
- buy spare OEM battery - I'm against aftermarket batteries, they are all fake rated
Or just buy latest iPhone 5 and enjoy.
Remember: Android is for tinkerers! That's why we love it! :victory:
Why do people still use some sort of battery management app life JuiceDefender or the like.
GET RID OF THEM NOW !(most of you that use it are probably coming over from an Iphone so you may be new but aren't well educated in how the Android OS works)
This phone comes with its own Task Manager as well as removing unwanted apps that are running in the background that you have previously used and don't need running.
So get rid of these dumb apps that don't do anything.

I like the VZW GNex a lot after trying a lot of different devices. Reason is because the Verizon Nexus is as close to vanilla Google.
What I don't like about it is the battery life.
Is there a solution?
Not really.
VZW GNex is pretty atrocious when it comes to battery life. The best you can do is fiddle with kernels, but don't expect miracles.
Before you ask, every phone is different and each responds to kernels differently. You'll have to personally try each one to find the one that gives you the best results.
Its only bad when using mobile data extensively. Its perfectly fine on WiFi or using data in a strong signal area. Its still better than the majority of the 2011 lte phones on mobile. The s4 phones do a lot better on mobile though. I personally have had very few issues making it through the day with battery to spare. I have found that it drains very little during idle which is not the case with a lot of phones which seem to wake lock quite a bit.

I couldn't believe how bad the VZW Galaxy Nexus was with battery until I got my GSM Nexus. I have easily over double the battery life with a smaller battery.

The Gnex has amazing battery life compared to the Rezound. I had the Rezound for a year and the battery life was abysmal. It lasted a whole 4-5 hours even with it being underclocked to 384 while the screen was off and with a screen on time of about an hour and brightness anywhere from 50-75%, it also came with a 1650 MAh battery. I got my Gnex about a month ago off of ebay and it came with the 2100 MAh battery and I've been using that and it easily lasts throughout the whole day. I have it underclocked to 192 when the screen is off and even with about 2-3 hours of screen on time I get easily 8 hours out of it. I would stream pandora over LTE for an hour in the morning and an hour in the evening and intermittent usage in between, by the time I would get home about 9 hours later I'd be at like 20%.

I got my Gnex about a month ago off of ebay and it came with the 2100 MAh battery and I've been using that and it easily lasts throughout the whole day. I have it underclocked to 192 when the screen is off and even with about 2-3 hours of screen on time I get easily 8 hours out of it. I would stream pandora over LTE for an hour in the morning and an hour in the evening and intermittent usage in between, by the time I would get home about 9 hours later I'd be at like 20%.

I too went to the GNex from the Rezound, was night and day, the GNex battery is twice as good as the Rezound's was, remember that everyone, there is worse.

I have to agree with this. I have/had the rezound with the extended battery, and I could barely make it a day. The Gnex has between 50 and 75 % when I get home. The rezound would be between 5 and 40 %

Running 4.2.2 I get 9h of standby and 1h screen on at the most on a HSPA+ Galaxy Nexus using a OEM 2000mAh extended battery.
I checked wakelocks and there was nothing out of the ordinary. Anyone else getting this bad battery life?
A phone that dies half through the day with light usage is pretty much useless. (I've had to use the 1750, 2000 and the 3800 battery to come through the day.)
Depends if you have any apps syncing a lot or using the radios a lot.
Signal strength plays a big role in battery life as well.

Only Gmail/whatsapp sync a bit, the rest is all turned of/ wifi only. Used gps maybe 20min for google maps ans public transport.
Signal strenght was mostly good with the occasional no signal, 10 min total.
Still, it shouldn't be this bad.

Try relocking your boot loader and flash a stock google img

btw im using sprints galaxy nexus running the unofficial xylon, with ak diamond19 kernel, with lte off, and pie controls.
Same here. I'll charge my phone to 100% set it down pick it up 15 minutes later 8-11% battery gone. No GPS, screen turned down, underclocked. I don't get it. I have a Toro also.. Just have to make due I guess till I figure it out.

I just started using a Nexus this week. I came from a RAZR M. The first thing I noticed was the lack of battery life. I found a couple tweaks to help with this issue.
They are: disable network time and date sync, 3g only till you really need to charge through some web browsing, undervolt to 1GHz, and minimal to 383 or so. I flashed the Franco kernel and use the Wheatley governor. Auto brightness was on auto. I also have the 2100mah battery.
I can almost reach 3 hours screen time per charge. I didn't realize that's a feat so I haven't taken a screenshot. My M got around 5 hours screen time. Ugh.. But the Gnex has won me over.

Something is definitely wrong bro... I have the same gsm model with the stock battery. With light usage I can easily go about 36 hours off the charger with 3 hours screen time. Sync with Gapps, Facebook, Keep, Drop box, Google +
Something is Jacked up somewhere...

Use trickster mod to see if your device is deep sleeping. I've had deep sleep issues on 4.2.2

And if you undervolt too much it will actually destroy your battery life

My device is deep sleeping fine, it is really a 3G/data issue. On wifi I can get 4h screen on and days of standby, no problem. But on mobile data my battery just evaporates in thin air.
I think the real problem is the 3G radio power management, that was excellent on 4.0 or 4.1 (never had issues) but on 4.2 it is outrageous.
The thing is, on wifi (home/work/...) I have the possibility to charge my phone. If I'm on HSPA+, I haven't.
My stats on wifi at the moment: 2h standby, 35min screen on 89% left.
Select 2G only if you do not really need 3G or LTE for phone and data! For simple phone calls or texting, the quality is not much different between 2G, 3G or LTE. In fact, in my city, there is more 2G than 3G and LTE transmissions.
It will at lease save you 30% battery.
I can put my phone on 2G only, but than I can't search something when I'm on a call, get delayed sms (really noticable). Not mentioning 2G is a pain in the ass, even for IM and email.
And constantly switching between 2G and 3G is also not a good option for battery life. Turning LTE off on a maguro won't do anything.
It doesn't matter how many features you turn off, battery life will not improve. Your phone will become a dumbphone and it will still die on you. I recommend to stop turning on the screen constantly and use it lightly. The screen used on this device is not efficient at all. I hope the next Nexus greatly improves on battery life or I'm switching to something else.

Android OS is high, BBS will tell you what it is, it's usually a kernel wakelock. Also if you don't use Maps, disable it, because since they brought the offline prefetching, it starts services like mad and runs in BG. Android AOSP has it's own location services and MapView, so you won't loose that.
My phone has become almost unusable after receiving the 4.2.2 update (on Verizon, totally stock phone). Battery has gotten as hot as 113F at times, and I can watch it decrease 1% at a time very quickly...
BBS keeps pointing to Exchange. I removed the account the first day and added it back in and that seemed to have helped initially but now is no longer the case. I haven't wiped the phone in over a year plus so this is my next step.
Is there any way to see what apps were recently updated?
Same battery problems for me (maguro). Not long ago I could use the phone for around 48 hours without charging, and suddenly one day to another it all changed and is drained within 9 - 10 hours. I have tried everything:
- monitoring with betterbatterystats (nothing out of the ordinary),
- tried different roms (including stock 4.0, 4.1),
- tried monitoring with betterbatterystats without any apps installed (disbled google apps to prevent syncing), without wifi / 3g / location services / NFC etcetera, even without sim card. --> No big battery draining wakelocks.
- tried different kernels
- tried new battery
- checked if phone was going into deep sleep (did that fine)
All without any impact, the battery life is still very bad (easily draining 5+ % per hour, if it is on standby all the time).
I'm starting to think it might be a hardware problem, I don't know what to do anymore without sending it back for warranty.
3 initial things I always look for when diagnosing somebody's battery woes:
1) Have you loaded (adb then fastboot) the totally stock nexus images from Google's website? At least for 3 days and no additional apps installed
2) How old and what is the usage of your OEM battery? If you're using a 3rd party battery who knows what will happen
3) What's your signal strength like in your daily travels? Bad signal will eat your battery almost as much as screen time
If you still have bad battery after thinking about those 3 questions then you have a unique situation. Otherwise, your problem might be simpler than it seems
IMO, turning off gps/wifi etc doesn't really help with battery life, at most 1-2%. Usually what causes battery to drain faster is when apps prevent the phone from sleeping, or if they're constantly running in the background.
