On my Galaxy Nexus was 4.2.2 takju version and at rhe time was locked and non rooted.
I have downloaded Google factory image for it. Then I decided to unlock boot loader since I was going to flash factory image.
Everything went well. No trouble at all.
So now I am on unlocked bootloader and still rooted.
But now battery performance seems to be poor (much worse then before).
Any ideas?
Any solutions?

How is that poor battery? If anything that's considered good, especially on a 1750mah battery, what did you expect?

Used to be better on 4.2.2.
Look at the break on blue line which indicate WiFi was off in that period.

Yes, and your screen shows 57% which indicates it clocked almost past 2hrs+ onscreen time. Users need to understand 4.2.2 was a broken firmware there's nothing good about it, which is why the update was skipped for 80% of the OEM smartphones and directly onward to 4.3
Custom kernel's may solve this problem for you but you need to consider the technical aspects and coding that went into this, smooth experience comes at the expense of something, also custom kernels stick to a min freq of 384, stock kernel runs at 500+ and 1026 on the N4. Considerably for mpdecision that handles all the tasks, that's considered good.
Also, how is this general? This should be in the Q&A section.

I thought that I'd mention that 4.3 also dropped the min. frequency on the Galaxy Nexus to 250, IIRC.

I just receive my extended battery today but wanted to show everyone my up time before I shut the phone off. Phone is just as stable as the 1st second of up time. Minimal apps....stock 4.0.2 ota, unrooted and locked bootloader.
Very happy with it and anyone who has wake locks and sod needs to remove some apps that aren't compatible.

My up time is currently at 820 hours!

just goes to show you how hardened the android kernel and frameworks really are. on my nexus one even i would routinely go 500 hours and still running as if it were just rebooted. my galaxy nexus is just as stable!
My up time rarely gets past 2 or 3 days! (It's hard for me not to flash a new ROM or kernel )
I'm curious if this would work with a ROM like Bugless Beast if I were to relock the bootloader after? I would go back to complete stock for the stability and battery life, but I really like the default wireless tether options from the AOSP build.
Quick side-note: I always noticed with my Nexus S that when I used it completely stock, I got better battery life than any ROM I used, including if I kept it stock and just rooted it. Not really sure why that is, but I imagine the same applies to the Galaxy Nexus. My girlfriend has hers completely stock and gets better battery life than I do all the time.
Cool serial number you got there...

720 hours and counting so far...hasn't rebooted once since I bought it!
I had my first reboot today. I was at the park with my girlfriend and dogs and she asked to take pictures of them so I handed her my phone and it unlocked but froze on the home screen. Lol, I told her it wasn't frozen and she probably did something wrong so when I grabbed it, it was on the home screen and went to the Google logo. Womp womp

I've tried about 3 different custom ROMs and stock, I think I've had a single reboot. Was it stock? I can't recall. I wouldn't exactly call it a crisis.
Ugh, I wish I could challenge those uptime scores! My Nexus has only crashed once since I got it and it was due to my own fault with charging with low voltage while using at the same time.
I just change SIM cards every weekend or every other weekend due to my trips to my girlfriend which requires a reboot. But yes, I love stability of Android!
Hey guys,
so yesterday i FINALLY flashed the 4.0.2 yakju factory image because i was just sick and tired of waiting for updates (was on yakjuxw 4.0.2 before).
I flashed the .2 instead of the .4 because i wanted to see if i actually do receive updates faster but that has nothing to do with this thread (didnt get .4 OTA yet btw).
So what i noticed with the stock yakju build is that i just get like half an hour mor battery life than on the yajuxw build.
On yakjuxw i got like max 3 hours screen on time if i was lucky.
Now i got more than 3,5 hours screen on time with actually playing much angry birds bubble shoot etc., browsing and xda app.
If yakju really gets more battery life that would be one more major reason to go for it if you're on yakjuxw!
Here are the screenshots on the yakju build (everything stock), sorry i dont have screenshots of the yakjuxw build...

try 4.0.4 . with that one I've got around 4:25 hours of screen on time!
Would be cool... but it seems like i just won't get the OTA
Why don't you just flash a factory image from the Google site. They already released the factory image of 4.0.4 there.

Hi all. I have a gnex that has horrible battery life. I have tried using the stock battery and the OEM extended battery however I will only get about eight hours of use. I am running cm10 with lean kernel. I have overclocked, under clocked, and undervolted but has made no difference. I am including some screenshots so someone can try to help me or at least tell me I'm not alone lol.

How much screen time? Press screen in the battery option.
Sent from my SPH-D710 using xda app-developers app
1. Don't overclock
2. Don't use LTE
3. Keep your screen as dim as possible
4. CM isn't really known as a battery saver rom. Its more of a performance with stability type rom
5. Test out other kernels.
6. Check your apps to make sure you don't have one that's killing your battery
7. GPS should be off
8. Turning sync off will help too
Oh ya and questions go in the Q and A forum

If you're constantly in areas with low signal and data on, your battery will drain from trying to get a signal.
Sent from my Galaxy Nexus using xda premium
Well it seems like you're using the phone pretty hard on LTE with a 1.6ghz overclock... Sounds about right.

Yes, way overclocked. Is your phone actually using that frequency and is it stable. Lean exp. 5 can under clock on the low side to 180. Try that.
Actually your battery life seems quite normal.
Some folks are saying that Diet kernel gives great battery life. I haven't tried it yet. I'm wondering if it will slow my phone down too much. I'm loving the speed and stability of Lean kernel.

I'm new to the Verizon Galaxy Nexus (Toro), I just switched from a Thunderbolt.
So here's the issue: I am seeing much quicker battery drain than I would expect when running Carbon 1.1 (Android 4.2.2) or Carbon 1.0 (4.2.1). I'm going to try franco kernel today. Here are some screens showing stats. I replaced the stock battery (person who sold it said it wasn't holding charge) with Anker battery. I also disabled NFC wondering if maybe this battery doesn't support it.

Any advice would be greatly appreciated, maybe I missed something with installing the rom with this phone, as I said before, I am new to the Nexus.
You might can squeeze a little more, but </= 2 hours screen on time is generally what you can expect.
Seems pretty normal to me. With almost an hour of onscreen time 53% after almost 7 hours is pretty good.
Alright, thanks for the input. Sort of not what I expected, as this isn't much better battery life than my TB. Would anyone expect an improvement using just 3G? I don't typically use data on my phone anyone, as at home and at work I have wifi

Not a substantial one, no, but minimal improvement maybe.
EDIT: Unless the majority of your battery drain is coming from data usage.. Torrenting and such..
I somehow noticed a much better battery life in 4.2.2 than 4.2.1
I am running ParanoidAndroid 15th Feb release and AK 691 Pirates on my maguro.
I have disabled sync and only sync mails 2-3 times a day and complete sync once.
And screen on time between 2.5 to 3hrs is normal for the GNex.
Please my phone litterally died in 3 hours from full charge with 1hour screen on time
Running FINAL SOurcery and Faux 29u kernel underclocked at 1000 mhz with intelli demand
First things first, don't ask "best" type questions on xda. Everybody has different experiences.:good:
That being said, I am personally always running the latest AOSPA (Paranoid Android) and latest AK kernel. Great ROM, and absolutely perfect kernel. I usually get around 3 hours on screen time with that combo.
Of course, you have to remember that there are many many factors that impact battery life. For example, if you have data turned on (either 3g or 4g), gps on, or brightness high, your battery will suffer. Search the forums for various ways to improve battery life.
I always have the best results running stock for battery life.

^^^This. If you are having that crappy of battery life, its most likely the battery itself. No ROM or kernel is going to help you.

This is heavy use (3G only, no WiFi) also I'm with wind so having a crappy network signal kills it even more, yours will most likely look better.
