first off there are some ways to calibrate an battery without any apps..
BUT.. your battery is brand new and hasn't reached its potential yet, so calibrating is useless.
If you have battery issues, try getting an update to 4.0.2 + radio. your on XDA you'll find enough info here.

I do believe the battery gets better after a weeks use or something like that.

Galaxy Nexus Battery Life

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.

Battery Life

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.

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.

Battery App
I've tried to find a rom and kerneI that would help with battery too, nothing made that much of a difference though. I use the 2x battery saver app now. I get at least double the battery life sometimes more.

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.

Strange battery issues

Hi.
I've got a strange problem on my gio. The battery is draining quite fast and when there is only one percent left it switches off. If I plug in the charger now I see, that there is more than half of the battery left. What can I do to use this battery time as well?
I already wiped battery stats and made a battery calibration but there was no change after that.

Same problem here.
I've tried some ROMs and since then, the battery is a disaster.
Charges really quick and drains even faster. I am talking about 15 min with wifi or 3g before it dies.
Help please!!

Might be the problem... Otherwise it's dead I'm afraid...

In my opinion it could be a dead battery.
If you couldn't solve your problems with the other links, buy a new battery.
In my case that helped.

Yes it was the battery. I just bought a new one and it's lasting for ages now )

Battery usage spike

I'm not sure what's going on with the graph from my battery usage page. For some reasons, it would jump to 100% which is impossible. Anyone of you has seen something like this before?
Thanks in advance!
Sent from my Nexus 7 using xda app-developers app

Same here... Every discharge cycle. But performance and battery life are not compromised....

I noticed the same thing today for the first time. But not as bad or as much as yours is showing.

I see those spikes on my Nexus 7 2013. And I get a terrible battery as well. My tablet loses about %30 of its battery charge during night when it is in sleep mode. Does anybody experience the same issue? Is there a way to fix this?

You must have an app installed that's causing that much drop off. Mine drops off like 2%.
Sent from my Galaxy Nexus using Tapatalk 2

I have seen spike on mine, too, but not up to 100%, only 1-2% more than its actual level. I thought it's because it was the first charge cycle and the reading weren't yet calibrated. I'll see if they go away after a few more cycles.
I don't have battery drain, as well, I lose 2-3% overnight with wifi and sync still on.

You can try an app called BetterBatteryStats it gives you a more detailed look at what's using your battery.

Hey everyone,
My Nexus 7 (2013) is having the same problem with battery graph. There are about 2-3 spikes to 100% in every discharge cycle.
I noticed this problem has been reported in different cycles, but no one seems to be able to give a definite answer of what the source of this problem is.
BTW, after a reset to factory settings, the problem still persists.
ANY idea why this is happening???
