Battery issues

My phone has TERRIBLE battery life. It lasts about 2 hours usually and sometimes 2 and a half. I'm running the stock GB from that came with the phone, but I am rooted. I have tried every single from out there..none of them give me sufficient battery life. By the time i get home from school by battery is down to 30%. What could be causing this? I'm also on my third warranty replacement phone and my second battery.

Normally I would suggest going to stock for people but in your case, maybe custom is the answer.
Do you have loads of apps and accounts setup by the way?

This really has no useful information to be helped. 2 hours? On stand by, screen on time, any cpu tuners, etc?
Maybe take screenshots of what the battery chart looks like and what apps have the highest percentage.

It is about 2 and a half hours of screen on time. And I can't get a screenshot of it because I just flashed a new rom, and my battery hasn't had a chance to settle in with the new rom yet. If it doesn't improve I will post a pic of my battery stats. Thanks.

Well, I'm guessing there is an app that keeps running constantly. You should try an ICS ROM, that might help.

Same problem
I've been experiencing identical issues with my T989. I've had terrible battery life without many apps running in the background (as I use the stock task manager to execute all running apps). I've finally decided to root my device and install a 'set cpu speed' app. Even though I've set my minimum cpu speed to 200 MHz and max to 800 MHz it's still lasts for a maximum of 4 hours until I get the "Battery is critically low" message.
Does samsung provide warranty for their batteries? Because I've called to complain about battery life and they asked me to remove the battery and send the device itself so they could repair it. And under no circumstances would they offer me an exchange for the battery, maybe I just caught a bad rep?
I love this phone and all it's features and prefer this over the iPhone but I feel like i'm being forced to just purchase the iPhone 4s.

Sprint nexus gets hot... Kernel?

If I use it more than 10 min it starts warming up.. 15-20 min and it almost burns to the touch. Is this a kernel issue? I do have a custom kernel running.. Could anyone recommend a kernel? I am currently running teerom

yup, thats hot!
what are you using when it gets so hot? watching a movie in flash will do it, gaming will do it when plugged in(but youre not plugged in). my guess is that the lte 4g radio could do it also, especially if its trying to connect but cant. ive heard of verizons galaxy nexus getting very hot with the lte radio on. my gsm gn only gets that hot when its overclocked highly and im putting it through a tough benchmark regiment(when trying to get it that hot). it could also be a defective battery.

I've had many sprint phones get hot while downloading lots of data over 3G. It particularly happens when I do "update all" in the android market while on 3G. Burns through battery power real quick.
This is mainly due to sprint's crappy/obsolete 3G implementation trying to keep up with modern data demands.

I'm having the same issues. I might just sell the phone for now while I can for around 400$ then re-buy it once it hits a lower price

deleted post.
move along, nothing to see here..

Just an FYI, that screenshot is a picture of the battery temperature. Not the CPU temp. I believe that the maximum temperature the Galaxy Nexus' processor can withstand is 100 degrees CELSIUS, not Fahrenheit.
At deep sleep the lowest my CPU reaches is 80 degrees F and my CPU is ALWAYS around 95 degrees F when in light use and rises to about 145 degrees F when browsing or using an app.
And I believe you must be rooted to check CPU temperatures anyway. Franco's app shows the MPU temperature and you must be rooted to check it.

Please help me with my Nexus

How do I get this phone to hold a charge for a day? Right now I get about 6 hours of battery life if I am lucky on decent use.
It is rooted on a black ice rom, running that Franco kernel. Is there something that I am not doing? Do I have to overclock it or?
I seriously almost traded it it for an iPhone just because of the battery issue. Like, it drives me insane and it takes away my freedom lol
Any help would be great

if you're only getting 6 hours, then you're a heavy user. Not much you can do about that, except use your phone less or charge it more.

Run stock for a while...
Sent from my Galaxy Nexus using xda premium

I'm on sprint and out of the box it was bad bad battery life. I'm sticking with it though hoping someone comes up with a way to get better life out of it.

Use an app like CPUSpy to see if your CPU is ever going into Deep Sleep mode, and an app like BetterBatteryStats to figure out why not. You can also look at Settings > Battery to see what's using up your battery. Tapping the graph at the top may give you more details.

I really am not a heavy user.
So switch it back to stock?

Usage varies man .. i have decent battery life so far with Franco 185 linaro with AOKP linaro rom. I keep the governor set to conservative . And I do overclock as much as I can ...might even be better if I didn't do that . But I get around 10- 14 hours on that setup . I text a good bit and twitter occasionally but spend most of my time on flud news reader. If you stream music all day or Netflix or something then you aren't going to get great battery life .
Make sure your screen brightness isn't high when you don't need it to be ..since the screen is generally what uses the most battery .
My best battery was with lean kernel and slim rom 4 ...but since I went to this new linaro I will forfeit a little battery for fluidity.
The key is just to experiment. There are lots of combos out there and they all work differently for us. There isn't exactly a one stop solution . Just tinker and you will find the light
Ps: I have the 2200 extended battery from Verizon . It is a necessity if you wanna get normal usage. They are listed at forty bucks or something through Verizon ...but if you go to the store they sell them for 20.
Sent from my Galaxy Nexus using xda premium

Best solution would be to get an extended battery to last you the whole day or an extra cheap one to swap with at the middle of the day

Yes, do this before blaming the phone. Also pay attention to the apps you install and see if any of them are causing the problem. Stock roms are usually less buggy than custom roms.

You can try turning screen brightness down, check your apps and see which are battery consuming, turn off any auto syncing, unless you play intensive games you can scale back the CPU. That may help some.

This is average battery life on the galaxy nexus. Check to make sure your not synchronizing your email or social networks to often. Also pay attention to your data connection. If it is poor your device will be constantly seeking for a signal.

Set the clocks back to stock. I find Franco kernel to be smoother on the 1228 max speed. Set the min to 384.

Really depends on what you do with the phone and how high brightness you have set. You can get more than 2 hours from it. You should be able to anyway.
My screen has been on for 2h3m as I type this. 23h14m since last charge and I have 39% battery left now. I think about screen brightness though and adjust it manually all the time when needed. Also screen-off at 307Mhz and max at 1Ghz.

You can maximize screen time on WiFi. Mobile data drains in the background, making your screen time appear "substandard".

If you all noticed that he has 700mhz as min so it's normally to drain fast.
Lower the cpu to min 350mhz and use lux auto brightness from play store to control the brightness.

I've gotten two days of standby life WITH 2 hours of screen on time.
So if you're only getting two hours screen on, you should be going at least a day or beyond on standby.
Otherwise, I can pull 3 to 4 1/2 hours screen on, I used to pull consistently 4 hours+ but whatever is new in the kernels or ROMs is stopping it.

I get the same thing . Why is galaxy nexus battery so terrible ? I upgraded for better battery life not worse

Rarely get more then 2 hours screen on time. Lately it's been much less. Screen brightness is a big factor, if you make your screen really dim you can brag about long screen times.

I'm with this guy. Around 2 hours screen time after 2 days (turned off while i'm sleeping).
I would expect more if you still have to plug it in at the end of the day. What apps are using the most battery? (as seen in the battery section of settings)

Most I have gotten is 3 hrs screen while on WiFi with the extended 2100 mah battery. And that was with no calls or music. I average maybe 2 if I'm lucky. I seem to get a fair amount of drain on 3g no matter the radio. Switched back to the stock 1850 mah battery to see if it treats me any better.

The GNex is notorious for how quickly the battery drains while the screen is on. There's nothing you can do, realistically, on stock, to fix this...custom ROM users usually have some tricks to increase battery life.

There might be an issue with surface flinger, I've never seen it under battery stats. Radio signal is crap here, what I can't seem to figure out is why don't you use airplane mode ever since your contract was terminated.

For battery life you could even try a mild underclock. This is will may or not help, depending on what kind of apps (and processor usage) you run on the background.

It's definitely the signal because I experience it first hand when I go back and forth to visit my parent's house. They have atrocious signal reception (One bar for 3G) and battery drains around 3% a minute. It's a lot different when I'm at my place with full 4G signal because I can get 4+ hours on screen time.
It's unfortunate one of Google's flagship phones was designed poorly in signal/battery efficiency. Oh well, what can you do.
