I don't know but for some reason battery life has been horrible since I switched to beastmod yesterday it lasted only 6 hours and 45 minutes when the phone was on 3g. When I'm on wifi, I get around 19 hours. No offense to the developer (it is a great ROM) just curious as people on this forum have reported
excellent battery performance on this ROM.

Battery life for me was better then stock. With regular (periodic) use I would get around 23 hours, with heavy use around 12 hours. Could be the install or wipe the battery stats.
Let the battery do like 3 or 4 cycles..

I'd recommend an app that helped me extend my battery life. "Traffic Monitor" by RadioOpt GmbH. I was able to identify apps that were eating up data and battery.
I have been having bad battery life for my Galaxy Nexus. I got an extended battery and it helps a bit. Any suggestions on how to extend battery life.

You should give us some details on your usage. How about some screenshots of your battery stats page after a full days use?
install betterbatterystats as it can help you find what's hogging your battery. It's on play store but also available for free for xda people. Google it and the free version should be the first link.

i hope you are not using stock kernel ... sometimes it helps alot to change it (to replace stock kernel).. i haven't tried on my galaxy nexus yet .. but on my htc wildfire .. it was clearly noticeable ...
Franco kernel, it takes very much longer battery life.
There are also programs like Jucie Defender, ...
Often there is a program that takes a lot of power, just look under "Battery" ...
Stock kernel is fine. I get 4½ hours display time with auto sync with auto brightness on rooted stock 4.1.1. I got the same using various kernel/ROM combos on ICS. So no, there's nothing wrong with stock kernel.
Did I mention that's in a 20 hour day with stock battery!? And there's already like 20 of these threads.

Yes, in 4.1.1 the battery consumption is much less.
Easy 24 hours on one battery charge ...
Jelly Bean battery life is awful

Which ROM are you running? I'm using ViciousV5 and the battery life is awful, I have a 3800ma battery but I really need a car battery with this ROM. On 4.0.4 the phone would run for 30 hours, now it's good for 10 hours.

Figured I start a thread specifically for the T-Mobile variant. I will say that I'm pretty pleased with the battery life thus far. I hated having to give up the ease of some functionality just so my Samsung OG Epic 4G could make it through the day. Meaning, turning off bluetooth, live wallpaper, wifi, etc.
I feel like I haven't had to do that even though there is a battery saver mode already. I'm currently sitting at 54% and it's been a day since taking it off the charger.
I currently have all the bells and whistles going. Live wallpaper and facial recognition to unlock. S-Pen detection and the whole 9. Anyhow, just wanted to see what everyone else is getting.
I'd be happy with 6 hours screen on time
i had the galaxy s3 before the note 2 and i have noticed huge battery improvements
I was briefly reading through the manual and saw this:
Do not wait until your battery is completely depleted before
charging your device. Repeating this process of a complete
discharge and recharge can over time reduce the storage
capacity of any battery.
Pg 15
just thought I'd pass it along. I usually run my battery all the way down and let it die before recharging:

dam thanks i was about to do a few full discharge and full charge again, thanks for the info.
I'm not getting great battery life yet and have had the phone for over 24 hours since I picked it up yesterday morning. Can't pinpoint wjat could be draining it.
What do you guys think?

My guess wouod be your cell signal. Lot of yellow in there. Weaker signal means more battery drain

Unbelievable. Its DOUBLE what I get on my note 1. This is the first time i can remember in years not changing a battery during a day.
I have had WiFi on most of the time.
I never thought I would see 14 hours.

The battery life on this is simply amazing. I am still shocked to see how good it is. I tried everything today to run it down. Barely even used WIFI today. Basically all 4G. Screen brightness was about 50% at least all day. Never below as well. Crazy awesome battery
My battery life is insane. Ive used my phone nonstop all day and its still going. I should easily get between 8-9 hours of onscreen time.

Battery life is very good compared to the previous releases. I ran for forty minutes with Bluetooth turned on while listening to tune in radio and using endomondo app. Google now turned on. I lost fifteen percent compared to losing 35% with similar usage. Very satisfied.
What do you think?

Ditto. My phone ran like a champ on a freshly flashed ROM. Then my phone realized it was born as a Verizon-Nexus mutt and had a psychological breakdown to the point of 1.75 hours of on-screen time the day after.
Twas a sad day
I'm reading my work email over the exchange service account. After upgrde to 4.2 the exchange service process eats my whole battery so I can't tell about any improvement.

When it comes to battery life (in general, though especially true with this newest release), it's crazy how many divergent opinions you get. Some people claim to get amazing battery life (exactly what quantifies for amazing?) and some people claim the battery life is crap. This is just to remind you that unless you have a good way of measuring battery life, your measurements can be plus/minus hour(s). Someone who just leaves their phone on a black screen with no wi-fi and cell may get 10 hours of screen-on time. Someone who is watching videos with cell/wi-fi might only get 2 hours of screen-on time.
In the future, I can make two recommendations:
Always report a complete cycle (from 100% to close to 0%). This is because the battery does not discharge at a constant rate.
Always report screen on time
Average for GNexus in previous builds was 2-4 hours. I've no idea about the plus/minus, but they tend not to be under 2 and over 4 with moderate usage. I think an average of 3-3.5 hours is what most people are happy to report.
And that is really sad because my old atrix used to get over 8 hours on Wi-Fi with over twelve hours of standby time. I wish they would make this phone but with a smaller screen size. The technology used on this phone is not battery efficient at all.

This tells us nothing....u don't show ur screen on time and uve been charging off and on..
Battery life in sleep mode is worse for me. I am losing 3% an hour with the screen off, I used to lose only 3% total overnight with the screen off not per hour. I tested this over the last 4 hours only waking the tablet up long enough to check the battery level and it has gone down by 3% each time. Nothing has changed with any apps or setting since I upgraded from 4.1.2 to 4.2. I got concerned when I noticed this morning that my battery was over 15% less then when I went to sleep. Anyone else notice this?
This is very good battery by my standards.

I recently bought a GSM galaxy nexus (NTT DoCoMo version) and I use it on T-Mobile's prepaid network. The original battery that it came with was terrible.. Literally only lasted 7 hours regardless of screen on time. So I bought a stock Samsung battery off eBay thinking maybe it was a bad battery. No help whatsoever. I've flashed different ROMs, radios, and different kernels. Can anyone help me figure out what's going on? I had a Sprint Galaxy Nexus and I could get up to a day on the battery with 2.5 hours of screen on time so I know the Galaxy Nexus can last a long time. What's the deal?

Could you post some info on battery drain statistics from battery settings tab or preferably gsam monitor over a full drain? I could probably help you out, just need some more info. Also try flashing fancy kernel if you haven't already. This is a newer kernel that gives the best battery life you'll find freshly flashed.
Before discharging toget battery stats I would try charging to 100% and using "battery calibration" by NeMa to clean your phone's batterystats file and then drain to zero with a screen flashlight or running gallery slideshow. This can always be a problem no matter how healthy your battery is.

This is what I have showing for my battery so far. I flashed the newest radio last night and that seems to have helped a little bit with the battery. I have tried the battery calibration and it didn't really seem to help much.

I have flashed a stock 4.2.2 ROM a week or so ago and I was still having this issue. I bought a new battery too and its still happening. Flashed the fancy kernel today and it seems to be helping a lot actually.
Sent from my Galaxy Nexus using xda app-developers app
The stock kernel performs way better then what you are experiencing. A custom kernel may help a bit, but it's not magic. I'd recommend using the app BetterBatteryStats in order to find out what's going on.
Do any of you think that me restoring apps would have anything to do with the battery drain? I'm not seeing anything out of the ordinary in the GSAM battery stats but the battery drains way too quickly. 10% per hour even when I'm not using it..

Glad to hear that fancy kernel is helping. It's probably the closest thing to magic you'll find. I agree that 1 hour of screen time and under 12 hours is under par, but I was having these same issues 2 months ago and could not believe how crappy battery life was. It really got better though trying a bunch of different radios to find the right ones, using minimal gapps/resource hogging apps as possible, finding the right build.prop tweaks to use, and most helpful flashing some good reliable kernels like fancy and AK/anarkia that have incredibly useful customizations that stock just doesn't have, I.e., contrast and color settings, battery friendly governors and frequency profiles, optimized smart-reflex, and custom regulator voltages for display.
Well, didn't feel like it lasted too long. Fell asleep with my battery at 33%, woke up 3 hours later and it's dead. I'm ready to throw this phone out the window.

I see you got the app. Good. Now a few minutes isn't enough time to gather reliable stats. Review the results after a full drain cycle of the battery. Check partial wakelocks and alarms for suspicious activity.

Here's what was listed on BBS after a full drain. Do you see anything unusual? I turned my data on and kept it on 2G to prevent the no or unknown signal from eating more battery but that was the only change. Battery life still looks terrible.

No need for the snake oil app, as simply unplugging the phone after a full charge wipes battery stats. Wiping battery stats and draining to zero aren't going to have any bearing whatsoever on this issue and would needlessly shorten the battery's serviceable lifespan.

Whoops.. I forgot to screenshot those. I'll get those later today. So I put my phone in airplane mode to see if maybe it was the reception... Phone kept draining. I will try to wipe everything off the phone later and not install any apps and see if that helps.

According to these stats, it looks like Google talk and the calendar are my biggest wake locks? I disabled Google talk, turned off location history for Google maps last night, what should I do about the calendar? I feel like my phone is becoming useless because I have disabled so many things.
