Best battery life Kernel and Rom Combination for Android 4.2.2 for the Google Galaxy Nexus

So far the best combination I have found, after experimenting many android 4.2.2 on my GSM Galaxy Nexus is Parandoid android rom and Franco kernel, this way I was also able to fix colors of screen and enable fast charge feature through pc. this was possible using Trickster MOD kernel settings app and fast charge app.
just though to share this info to save you time, but if you have a better combo tell it in comments.

Increase Nexus Battery Life by Filtering Your Screen

Screen absorbs most of the Galaxy nexus or nexus 7 or anything, the bad news is that the lowest brightness in amoled screens are still bright, the good news that Amoled can be filtered down using a simple application and it actually works and saves battery unlike other phones or tablets with LCD screens where filtering is useless.

There is many applications but there is an application that can be toggled easily and small in size and doesn't use cpu at all, it just places a filter on top of your screen and you can darken that as much as you want, and it will simulate a lower brightness which is good for your eyes and brain at night and good for your battery.

Screen filter on Google play store it's free :D this filter is useful for Galaxy nexus owners AMOLED, Nexus S and Nexus 7 can go for the second option only.

Screen Filter: Reduce the brightness of your screen, save battery.

Reduce the brightness of your screen for night-time viewing. Applies a shade that acts as a dimmer to ensure your eyes don't hurt. Far more powerful than Android's built-in brightness setting. Great for low-light gaming, web browsing, and eBook reading. It even saves battery life for AMOLED displays!

Another tip is to use timed brightness that changes every hour instead of automatic brightness which sucks CPU just detecting and changing brightness.

Download advanced brightness from Google Play market - free and small :D works on all Nexus AMOLED or LCD.

Dual Booting ICS and JB on Galaxy Nexus Using Bootmanager

I downloaded boot manager from the market and tried to dual boot JB and ICS rom but it just bricked my phone and I had to repair my boot.img by re flashing it from /sdcard/bootmanager/phonerom/update.zip

I also tried installing a new rom from a nandroid, and flashing from zip, flashed ICS tried to flash another ICS  nothing happen, deleted boot manager and its files, wiped data, installed it, did the above all over again for almost whole day and in the end I give up.

my point of view, boot manager is too buggy and I don't know how exactly some people got this to work on galaxy nexus.

if you know how please leave a comment below and help me and for sure this page gonna be a reference for someone else.

How To Increase Galaxy Nexus Battery Life on Jelly Bean

I was able successfully to squeeze 18 hours of usage on average out of Galaxy Nexus, that's the good news, the bad news for some of you, you need unlocked boot loader, a custom kernel and custom rom.

I am gonna share what I did exactly.

1. Unlocked boot loader. you can google that if you didn't do already.
2. Flashed CWM recovery.
3. Backed up everything.
4. Wiped Data, formatted system, wiped cache, wiped davlik cache.
5. Downloaded and flashed AndroidMe 1.6.0 rom based on stock.
6. Downloaded and flashed Trinity kernel TNP1536-307-JB-STABLE35.
7. Wipe battery states.
8. reboot system

if you don't like the colors of this kernel you can fix them (my guide to fix trinity kernel colors easy tutorial that I wrote).

Setup your device and if you have a Titanium backup of your applications restore it.

Now to get more battery life, don't worry about wifi or data, you can disable NFC and location services, all of them.

Charge it, let it drain, charge it again and you will get minimum of 18 hours of usage.

if you like my guide and you love your new Galaxy nexus don't forget to share with your friends ^^.

Best Kernel and Rom to Save Battery on Galaxy Nexus

There is no best combination for best battery life on galaxy nexus people will tell you, but I experienced something which is best for me and hopefully will be best for you also.
I tried all kind of roms and kernels for my galaxy nexus you could imagine until this date, but what really worked for me when it comes to battery saving specially on jelly bean, this was my best.

• for the kernel I used Trinity Kernel
• and for Jelly bean this rom Androidme

But seriously I didn't like the color preset of Trinity kernel, so you can follow this guide on how to change your  galaxy nexus color preset (noob friendly)
