Buyers remorse - Samsung Galaxy Nexus

I came from the Epic Touch 4G and I loved that I could get 4 hours of screen time all the time on nearly any rom. On the galaxy nexus, I've gotten Max 2 hours and I've tried all kernels and roms so far. Am I doing something wrong or is this phone not optimized as well as the epic touch is at battery? I love the phone but I noticed to get speed out of it (gpu) it uses a lot more battery than the previous phone. Should I take this back and hold out for the evo lte? I got another week to decide. I do want to get lte though. Its not in my area yet.

The screen (and a few other factors) is just gonna drain a bit more on this device then the SGSII. Make sure you have LTE turned off (should be "CDMA only" by default).
Some of the drain is probably "new phone syndrome" where you're using your phone differently than your previous one because its new. Most people here are getting about 3 hours of screen on w/ 15 hours usage total, with normal usage. YMMV though of course.
When LTE comes on the drain will get worse. And it won't be solved by the Evo 4G LTE. It has (basically) the same sized screen and similar specs, but only a slightly larger battery (2000mAh vs 1850mAh)... don't expect it to do any better than the GNex.

It's literally the 720 lines of pixels that's making it drain faster? Craap. I have brightness on nearly all the way lowest, with GPS, Bluetooth and 4g off. I even have sound on silent. No haptic feedback aside from the soft captivate buttons. I like 720p but if it's going to drain faster then I may just hold off on it for now until a better high end lte phone comes out.
I used my epic touch to death consecutively and it never drained this quick, even on stock.

You must have installed something that is keeping the CPU alive. I have a GNex with stock battery running AOKP and Lean Kernel. I actually tested it with 4G off and screen brightness at Auto running slacker with the screen on continuously. I got about 3:45 min of screen time with about 20% battery left.
I would use CPUSpy to find out what is killing your battery.

I'm not necessarily saying that it's just the screen that's going to hurt the battery, but its the whole package. With a 100% stock phone I wouldn't at all expect more than 3hrs of screen on w/ normal usage.
As the above poster said, you may have something keeping your phone awake. Could look at an app like Better Battery Stats and monitor it for a couple days.

I love the Galaxy Nexus. Traded my Rezound for it. I get about 5 hours total battery life with the screen on using AOKP and the stable LeanKernel overclocked to 1350 MHz.

This is for CDMA.
EDIT: I was also playing games (Minecraft, Radiant Defense) for most of that time, while downloading a large file.

I did say CDMA....
Anyways, I'm not sure, check the links, ask the devs.

I just want to throw in my two cents.... I love the nexus because I can finally enjoy a perfect AOSP ROM without effort... It stops me from flashing ROM's many times a week lol!
Oh yeah, compared to the E4GT, the pictures taken in portrait mode are actually saved in portrait for when uploaded to sites directly from phone or send over MMS to friends. No more being forced to take pictures in landscape mode.
LTE, I live in Los Angeles Country so I can't wait to enjoy LTE =)
Buyers remorse? No, I might thought sale the phone in 1 month though just to profit and buy the Evo LTE and resale on another contract and resale.

Battery life in comparison to iPhone?

Anyone here able to compare the battery life of the Nexus, to an iPhone 4 or 4S (a 4S WITHOUT the battery issue)? I've gotten amazing battery life on my iDevices. I can't imagine getting worse battery life again like I used to on my other Android phones.
And also, what battery solutions could I use if I want a bigger battery? Any extended batteries + covers out there I could buy? I don't just want an extra battery to replace during the day, cuz that'd be a pain.
Thanks in advance!
edit: I'm not a light user - I might go as far as to say I'm a heavy user.
not sure on the GSM version, but I can promise you the LTE model is going to be complete crap compared to an iphone.
on my old iphone 3gs, I could watch like 4 movies & still browse the net for a bit before the battery died... on my thunderbolt & rezound I could watch like 1 movie & then browsr the net for about an hour.
even if you disable LTE(or go into airplane mode for that matter) its only going to help slightly.
you will have to invest in an extended battery unless you are someone who does "light use".

My battery life is just fine, and I'm hardly a newbie. Perhaps you don't have your phone set up in an optimal way. You should have no problem getting through a day of normal use, and you can get through a day of heavy use without charging. With 3hrs of talk and 3 hrs of screen time (auto brightness), with push email, bluetooth, wifi, and gps on I was able to still get 15+hrs of battery life before it got under 10%. Not sure how you have your phone set up, but my battery life is just fine.

^absolute bollocks.
I'm not a newbie and have both devices. The battery life on the GN is absolutely fine, yes the 4s is better, particularly when on standby, but I can get a good days use out of either phone.
One thing that I found annoying with my NS was the time it took to charge, the GN is far quicker and similar to the 4s.

I've had 5 Android phones so I know that the GN battery life is better than most. I easily get a day of heavy use out of it.

Battery life its significantly worse than iphone 4 and galaxy s2. I've had a number of android phones and galaxy nexus has worst battery life of them all

Wouldn't know much about the iphones, but compared to my previous phones (Nexus s, and a HTC Hero before that) the Galaxy Nexus is NOTICEABLY BETTER. I have no problem going a full day on single charge with heavy use. Or two full days with light use.
these topics are useless. galaxy nexus is a dev/debug phone.
i spend more time with it connected to the computer than anything else.
why are people comparing android devices to apple devices. it's just plain useless.
Actually battery life is really good the issue comes with how fast the screen drains the battery. Considering smiled power consumption is based on lit pixels and there are a lot more here than the s2

Comparing to iphone is not useless at all since that is the alternative many are considering out coming from. Just because you use the phone mostly for development doesn't mean others do.

I have the following:
GNEX GSM
iPhone 4 (GSM on ATT) - work phone
iPhone 4S (GSM on ATT) - wife's phone
The battery life on the iPhones is about double what the GNEX is, easily. I can do two days between charges on the iPhone even with normal use. The GNEX requires charging every night.
Do I care? Nope. I charge my phone every night anyway and always buy spare batteries.
Who in the world is away from a plug at night? Do you live in the woods?
I just don't see what the big deal is. If the battery died in 4 hrs on standby, I can understand. But it easily cruises through the whole day.
That's fine by me.

Yep. For those who complain of battery life, I bet you are running lookout mobile, skype, and a live wallpaper, lol.
Download "colors" from the android market, set wallpaper to solid black. Don't run junk apps that are on 24/7 and watch your battery last all day long.
Simple, really.

Def worse than my iPhone 4. In my case I decided to stock on chargers rather than becoming a lighter user

Galaxy Nexus Battery Fix

Hi,
I just got my Galaxy Nexus, flashed with AOKP build 18 and i gotta say that the battery life is unacceptable. It drops 10% in less then 1h while the phone is sitting there doing nothing. Wifi, bluetooth, location services, GPS are off. All background apps closed.
It lasts about half the time my iPhone 4 does and it is a year and half old.
I see some people showing examples of how their battery last for more then 20h but all these are BS tests as they leave the phone on standby all day or have some very light usage.
Is there a real fix for this? Am i forced to drop another 50$ and buy Samsung's 2100mh extended battery?
btw i tried setCPU also to lower CPU to minimum when in standby but doesnt do much. I want a solution that will enable me to use my phone, not something that makes it last 40h in standby and then kills it in 2h when i use it.
please help!
So everyone that posts four hours of screen on time is bullshitting? Did you know the first 10% isn't even that accurate? If you're on Verizon turn off LTE. If you're on GSM and you don't get three hours of screen on time you have an app that is killing your battery. It is as simple as that.
Sent from my Galaxy Nexus using xda premium
Try toggling Bluetooth on and then off, then grab CpuSpy from the market and check out if the CPU is pegged at a certain speed.
Some builds of ALL the custom ROMs have had issues where the phone wont sleep correctly, high %-age of Android System process, etc.
I disagree that its silly to talk about idle time on battery, because idle time is the closest we can all get to apples to apples comparison. We all USE our phones differently, the closest we come to using them the same is when they are just sitting there idle (not quite exact because some people sync data, some people only have 3G, etc, but a lot closer than person A playing games for 3 hours at a clip vs person B browsing for 3 hours)
I *still* havent seen anyone come up with a template like setup to report battery life. Like you said it does me no good to know someone dropped 3% "overnight" without knowing how long "overnight" is, if they had 3g/4g/Wifi enabled or even disabled completely, sync on/off, etc.
Personally, Ive seen 1.5%/hr drop with my phone idle. Running AOKP b19, LeanKernel, interactivex governor, undervolted (-75 mA at each level from 180 mhz to 1200 mhz), 4G on, BT on, GPS on, sync on (1 gmail account).
I imagine with all that stuff running 1.5%/hr isnt half bad. Screen on time isnt incredible but its not bad, but again my screen on activities can (and probably will) be different than your screen on activities so take that with several grains of salt.

It's not the first 10%, it's all the time.. it drops for about 10% or more every hour. Less then 3h of screen time.
I'll give cpuspy a try and see if some app is killing my battery.
I used AOKP rom because most of the people in the thread were saying that rom fixed their battery issue but for me it made no difference.

Yea somethings not right. Off charge at 8am and its 4:30pm now. Got 61% left at time of this writing and been using it quite alot. Typically have about 75% left about this time.
I just use an AOKP like yourself and a custom kernel. I'm on the phone like every 15min reading emails, SMS, word feud, twitter news, Facebook, Gmail.
LTE EX Galaxy Nexus - AOSP KANG
Asus Transformer - 3.2.1 OC/UV
It's actually 2000 mAh not 2100 mAh.
You can use a custom kernel such as Franco Kernel. New version came out today and includes more battery improvements (according to changelog!)

As you can see, if my screen is on the graph drops, when it's off the graph flattens out and the battery barely moves. I used to be sick to my stomach of the battery life until I realized it was because I wouldn't put the phone down and always had the screen on thus killing the battery.

Just a word of advice. Whites consume more power on AMOLED screens. You'd probably maximize your battery a lot more if you went back to a "Ice Cream Sandwich" feel or at least apply a black themed MIUI.

I had something similar and it was recommended to me on these forums that I log out of Gtalk.
Before people come out and say it makes no sense - it doesn't really matter if it does or not - it worked for me. I get a full day out of a charge now, which doesn't really matter because as someone said above it's all relative. What DOES matter is that my phone is now sleeping properly, so the battery doesn't drain when the phone is idle. That's the part that wasn't working on my phone.
If you feel so inclined, give this a try and see if it works for you. Just log out of all Google talk accounts and see how your battery life is - you'll know within a day if it's helping.
Have you flashed the new radios yet?
You can also try different kernels and see which one works best for you.

I think MIUI is pretty much at the same state as CM9. Just lots of work needing to be done since ICS revamped Android in so many ways.

not quite.
can i preface by saying that there are two types of Gnexus's out there? the SCH-i515 (CDMA/LTE Verizon) and the GT-i9250 (HSPA+, AT&T).
The 2000mAh is for the HSPA+ version
The 2100mAh is for the LTE version.
i see a LOT of bad advice on these forums here.
my best advice to you (from one Verizon Nexus owner to another), is to keep at stock 4.0.2. Root it, and apply a custom kernel. Only apply custom kernel if you feel that you're still not getting decent battery life for a whole day on 4G stock ROM/kernel.
As far as I know, Verizon Nexus owners' max on-screen time with 4G enabled all day is about 3 hours MAX, and thats if you disable everything else but LTE, with very low brightness settings, and on extended battery.
imo, the next 4.0.3 or 4.0.4 update hopefully will mitigate some battery consumption issues.

Are you talking about 3 hours MAX browsing or just being POWERED ON?
If you are talking about just being on for 3 hours, you are GROSSLY incorrect.

4 hours screen on time including 21 minutes using gps for Sygic Navigation is not bull****. Stand by for up to 61 hours, easy.

You were on wifi the entire day.
You are using the HSPA+ version of the Nexus. HSPA+ version gets better battery life.
Try being on HSPA+ the entire day with wifi disabled. you will not be getting 4 hours of battery life on-screen time.

If you are talking about just being on for 3 hours, you are GROSSLY incorrect.

Please reread what i wrote. MAX ON-SCREEN TIME.
it is not possible to go 4 hours of on-screen time with LTE enabled all day.

Most of the time I was on wifi, but not all.
But fair enough, I will test on 100% without WiFi. However, we don't have HSDPA+ unfortunately. Only HSDPA or 3G.

I went 13 hours yesterday with LTE on all day and had almost 4 hours of screen on time. I'm running stock ICS unrooted and all of my sync stuff is enabled. I'm also using the extended battery.

would like proof. afaik, its impossible to get 4 hours of battery life with LTE enabled all day.
sounds dumb, but are you sure you have Verizon's GNexus? Your profile shows an AT&T carrier... otherwise you should probably update it.

Yea somethings not right. Off charge at 8am and its 4:30pm now. Got 61% left at time of this writing and been using it quite alot. Typically have about 75% left about this time.
I just use an AOKP like yourself and a custom kernel. I'm on the phone like every 15min reading emails, SMS, word feud, twitter news, Facebook, Gmail.

I think the Kernel is what makes the difference. It seems to be the only difference i see between myself and the people like you have a reasonable battery life.
which one do you recommend? And i'm a noob at this so could you point me to a thread the explains how to flash it? If u cant its ok im sure i can figure it out.

[Q] Looking to buy a Nexus (Verizon 4G LTE, Hook Me!)

Hello everyone.
I might be trading in my Razr Maxx for the Nexus soon. I have 4 questions.
1. I come from a thunderbolt. That battery is horrid, do you understand me? HORRID. The Razr Maxx is a really nice improvement but I don't need all the juice which opened to me the oppurtunity to get the Nexus. How is the battery on it? I mainly make a few calls, text a lot, check email, and browse the web, watch the occasional 2-3 minute video. Will ROMs fix this?
2. I hear stuff about the signal being bad? It drops a lot? Then again I hear about this leak and it may fix it? What are you Nexus users thoughts on that?
3. How can you describe the overall phone?
4. Lastly, here's where you guys can go crazy, why should I get it over the Razr Maxx?
Why should you get a nexus? Read the dozens of threads in this section asking the same question, there's a new one almost daily. You're asking Galaxy Nexus owners about this device versus a locked down Razr Maxx, take a guess what they're going to say.
All the questions you asked can be answered by reading the threads, some are on the first page.

I'm bored, I'll bite.
1. I get about 3 hours of screen-on time with 3G, maybe an hour more if I'm on wifi. It will standby forever. Custom ROMs/kernels help a little with battery life, but not enough to really change your overall perception of the phone's longevity. I have the stock 1850mAH battery.
2. I generally doesn't display a signal as high as other Verizon phones, but some chock that up to other phones displaying the signal inaccurately. There are a very small amount of people who have legitimately low signal with their Nexus (which can be verified in dBm), and it's usually accepted that these units are defective. That said, I've had mine since 12/15/11, and I haven't dropped a single call or been without data.
3. It's got a nice form-factor (if you don't mind the plastic construction), the screen is great, and ICS rocks. I really like it.
4. RAZR MAXX has it on battery, that's about it. Ice Cream Sandwich is lightyears ahead of Gingerbread, especially with Moto not-blur and a locked bootloader. I wouldn't even consider owning a Gingerbread phone after having a Galaxy Nexus. The form factor is important; the software absolutely makes or breaks a device.
guess your right, I'll look around.
edit: Stad, read your post thanks. So it's not as bad as a thunderbolt (idk if you've owned one, it's like 7 hours w/ 4g minor minor usage). And it's not the best battery right? That's my deciding point right there.
Their is only 2 phones to buy.
A Nexus or an iphone.
Everything else is crap. Full of bloat and skins. Never see updates.
Lol, true.
I know there's always a bricking chance when screwing with root/bootloader shenanigans, but how safe is it on the Nexus?

Honestly I keep 4G off all the time unless I need the speed. I don't know about you, but I've found Verizon's 3G to have acceptable speeds for 99% of the situations I'm using it. The ROM I'm using (AOKP Milestone 3) has nice toggles in the pull-down notification bar, so it's really easy to turn LTE on and off if I need it.
I've heard of people getting better battery life. There's a guy over at Rootz who got 4h50m screen-on with AOKP and imoseyon's leanKernel on a standard battery, but I haven't been able to get anywhere close to that.
In real-world usage, the battery life is plenty. Yesterday I woke up at 4am and wasn't in bed until 11:30pm that night, and my phone still had 38% battery left when I crawled into bed. I forgot to plug it in when I fell asleep, and woke up to see it at 36% about 5 hours later. But, if it's not clear by now, not much of that was screen-on.

Unless you pull your battery while flashing a bootloader (which you might do once or twice during the life of the phone, if at all), you'd have to be trying pretty hard to actually BRICK your Nexus. The bootloader is unlocked with a single line in fastboot mode, and ROM flashes-gone-bad can always be recovered as long as the bootloader is borked. This phone is ridiculously easy to modify.
That's great thanks for all the info.
Did the rootz guy run on 4g or was that 3g, I'll find out myself if u link the post.
Now to stare at the two phones for 8 hours and see what I choose, lol.

battery life on gaming? good luck
lag once in a while
photo from stock camera are little bit washout
no facebook sync
Once the signal got dropped, it takes a while to reconnect.
all in all, i need to charge 2 or 3 times per day on average use (my average use). if i dont see improvement on 4.0.4 or future update, i am moving to iphone 5. i have been using android over 2 yrs now and still havent find any advantage over iphone.

I'm on Eagles Blood ROM, using Franco kernel. Stock clock with ondemand governor. All I did was undervolt 50mA across all frequencies. I was on wifi for most of the day since I was at home, but my typical work day doesn't put the battery under 50%.
The battery on this is way better than the one on my Amaze was, so that's all I really care about.

[Q] Terrible battery life?

I'm using AOKP b40 with the kernel that it comes with and I'm getting terrible battery life. I flashed Popcorn Kernel and Franco kernel once, but I had the problem where GTA III and other games would not start. I tried flashing the /bin/sdcard file but that borked the entire sdcard from mounting in Android so I had to reflash everything through adb.
I looked at Better Battery stats, and my phone is deep sleeping and nothing is wakelocking for longer than 5 minutes. I'm down to 67% after 15 minutes of screen on time and being unplugged for 2 hours. Is it just a bad kernel and should I try something else or is it my habits of using my phone? I'd like to get a lot more battery life out of this. I'm using the Verizon Galaxy Nexus with LTE turned off, GPS off, and Bluetooth off.
Thanks!
While my battery life is not as bad as yours, I too suffer from poor battery life. I can never squeeze any more than 2 hours of display on time at 45% brightness. I have tried AOKP and Slim ICS but they both give me mediocre battery life. I heard there was a franconkernel release which was by far one of the best released (r158?) I'm beginning to think I have a faulty battery as some people manage to get 4 hours of display time with descent standby.

Five minutes of keep awake is a lot for two hours.
I'm looking at Kernel Wakelock in BetterBatteryStats and it says PowerManagerService for 49 minutes. I'm at 54% now. I've been playing cached music for about an hour now with Google Play. Is there any more information I can give to see if I can rectify this problem?
Power manager is just charging. I would say that is a real issue though it shouldn't have dropped that quickly. What governor what frequencies and under volted?

I'm going to try with FrancoKernel and getting the sdcard file working properly tonight and see if it makes a difference. I leave it on overnight, it deep sleeps, but i still lose a good 15% battery. It's a bit ridiculous.

I don't turn data off, I keep 3G on. I have Facebook that syncs every 4 hours. My Google account syncs (not sure if there are intervals set elsewhere), and weather every 6 hours. Nothing else syncs to my knowledge.
EDIT: I didn't see your questions about my CPU settings. 1200MHz max, 350MHz min, interactive governor. I haven't touched voltages.
Okay if you can't live without sync your battery will always drain. Also change your governor to on demand or lazy if available. I usually just refresh everything manually and I get over 15 hours and 5 hours of display. Over wifi and maybe 2.5 of display over my terrible 3G speeds.

Strange......I'm in aokp b40 with popcorn kernel and the aggressive governor and just got a whole hour of screen time and was only down to 75%. It must be in app or something. Whenever that happens to me I do a factory reset and then reflash a different rom.

I've got to break the well spoken rule about battery life threads.

After long being one of those people who would never post a thread with bias questions or answers.
It's come to this.
I long for the battery I had from ICS, I never got less than 4 hours screen on and 16 hours standby together.
The best I got was right at 5 hours screen on with 18 hours standby.
All with wifi/3G only, very little to none 4G, it's fine with me.
AOKP M6.
_____
Every single ROM/Kernel combination since I've moved to JB has provided me with just......crap......
AOKP, AOKP kangs, CM, Liquid, CNA, and Eclipse along in different combinations with
Faux, Lean, stock, 007, TinyKernel, and Trinity kernels.
It does not matter what combination I use.
I can barely get over 3 hours-ish screen on time with about 12-18 hours standby.
Now if I use the screen less than 2 hours, I can get up to two days standby, which is nice but not the overall complete usefulness I had.
I know battery has long been an issue for many of us, but I see people in threads talking about their 2 hours of screen on time like it's amazing when it's awful, especially when some of us, could, and used to get close to 5 with stock batteries or 2100 extended (mine)
If you're using LTE all the time, only 2 hours screen on is justified because it should be common knowledge what happens.
Point of the thread is this, I want to know, those on JB with stock or 2100mAh battery and can manage 4+ hours screen on and still close to a day of screen on, what's your secret? Every detail, spill them.
Is it our fault or are we just in a down time of battery efficiency in the ROMs and kernels?
There is no secret, jb is crap when compared to battery usage on ics

Couldn't figure out why my battery life was so poor the for the last month or so. Good to see I'm not the only one with the problem.
AOKP ICS with Franco kernel gave me amazing battery life. Jelly Bean not so much.
I personally believe that anyone getting more screen time than you (this goes for anyone) is:
a) Using their phone in an environment that is less bright than you (indoors, on the bus, in the subway)
b) and / or not syncing as many things as you / not as often as you.
Reverse the above for people getting less screen time than you.
This is the truth of the matter.
Personally, I get 2 to 3 hours to 3.5 hours of screen time on JB, depending on usage.
4 hours if I read in bed at night.
Edit: Kernel / ROM be damned, maybe it'll make 10 to 15 minutes worth of difference. NOBODY has presented scientific proof of any ROM/kernel being different from any other. It's always "oh yaa best battery life ever with this rom". It's just noise and cherry-picked screenshots.

I usually get at least 1 day worth of charge. My set up is pretty easy tho. Since I am in front of a computer 75% of the time , gmail sync is turned off, twitter is @ 4 hours, Facebook set to never with location turned off. Phone gps and location are also turned off unless I M walking towards the bus stop. I don't need to be checking my phone every 5 minutes so my useage is pretty stable and predictable. I wonder what you guys are doing to make the battery die so quick? If your usage patterns are pretty high with checking email 100s of texts and lots of twitter and Facebook well yeah I'll die quick.
Also I seem to get the same results with custom kernels and stock. I have little experience with CPU controls and and such so maybe setting a lower frequency will help?

Battery can be related to many causes leading to user error. I never used ICS on this phone so I honestly have no idea how great the battery was.
Google now, project butter and many other optimizations are to blame yes.
Depends how much you use it and what is going and the vary of networks going on and off and switching. I can normally pull off 3-4 hours of near heavy use. My droid incredible could only get at least 1 hour max. So maybe it is me but the nexus is a godsend for me.
Leaving the governor at interactive with low max and undervolting will help battery and a specific kernel. I can normally roll with 0-10% brightness and have all networks running and syncing.
I'm tired and ready to cook my tacos I'll be back later with more input.

Try this...
I have an old Android phone that my boy plays with...so I turn the cell radio off & have it on the wifi signal only. Even with him having the screen on for hours & hours (usually playing games), the phone will stay on battery for almost 4 days!
Turn your cell radio to airplane mode & then turn on wifi only...mess around with it, play games & see what the difference is. When I have a Sprint signal (usually junk 2g one) at home I get poor battery life...when I hack the PRL to choose a 3g (better) signal I get twice the battery life...
I've seen other battery life threads where the signal is a MAJOR factor & even with a strong 2g signal the 3g is probably better at not wasting battery. (4g is a whole other story)
I've found 4 things that almost double my battery life
1) Google Maps: huge battery drainer. freezing it doesn't help either, it has to be uninstalled. Mapquest from the play store is a decent battery friendly alternative. or if you really need gmaps, copy the .apk file and install it when needed, then uninstall afterward.
2) Push Email apps: i.e. Yahoo mail app, Gmail app... use the built-in email app and set the refresh limit to every hour.
3) 3G/2G: when your not using data, put it to 2g networks only. huge battery savings especially if you're somewhere with a weak 3/4g signal.
4) NFC/WIFI/GPS : turn them off if your not using them (obviously)
your results may vary, but doing these things did wonders for my battery. I average 23-26 hours with 2.5-3.5 hrs screen on time. before that I was getting 14-16 hrs with about 1.5-2 hrs screen on

Well, Switching 2g/3g is pretty battery draining, too. So better be sure you don't use 3g networks for a while. constantly switching just to be a minute or two at 2g just drains more
Turning of WiFi is pretty obvious but NFC and GPS shouldn't take any battery juice if they arn't in use... Someone tested it and could proove, that gps only uses battery power if it's searching for a connection.
As you can see, you basically need t neuter your device and constantly worry in order to get 'great' battery life, lol.

Its a small battery, they should up the battery sizes. They can fit the samsung galaxy note 2's battery in the samsung galaxy nexus if they wanted too.. /the end.

yea I only switch to 2g when I know its just gonna be sitting in my pocket for a while, like when I'm at work. in that situation it definaetly helps. but your right switching constantly is bad too. :thumbup: as for NFC and GPS, it just seems to help for me, maybe its just placebo. like I said results may vary
