Sonic Team GS3 R5 / Faux 009 Kernel
This combo is extremely fast, low on power consumption, and maintains the stock features that make the S3 appealing but with added tweaks!

Yeah it was insane... Better than I could get with my razr maxx (regardless of what they claim you can get)
I was at over 4 hours with 35 percent left before I threw it on the charger for the night.

I have the same setup. Had about 17.5 hrs with 4 hours of youtube, 3 hours of facebook, 2 hours of talk. Still had about 20% battery left.

I am getting really good on battery time. But it seems like my screen on time is worse then before.... I am on one hour and 20 minutes of on screen time with 68 percent left. I did use a lot of four g Internet today while I was out at the outlet today.
Before I used to get about four to five hours of screen on time

I just did a AnTuTu benchmark... and i did not touch the rom/kernel in any way. And in my detailed scores it saying the clock frequency is under a GHz?? Is this thing really under clocked that much.. if so, no wonder battery life is much better. Check out the pic i attached, once again I did no changes.

Can trinity 43 be flashed via cwm or has to be Odin?

Could be throttling... Or depending on when the reading was taken could be correct. 1.8ghz probably isn't required to test sd card...
I have found that with faux kernel adjusting voltages has helped dramatically with the underclocking due to heat. I really hope morfic puts adjustable volts into a future kernel as these cpus seem to be hugely over volted (ymmv of course)

I am using this combo, for awhile now, and it is the most stable of them all.
Rom:FreeGS3 (GSN) R5 (thanks much redruM)
Kernel:Adama 003
Excellent battery life.
Might want to do flashes thru CWM, as it does not set off the ticker.
Although CM10 nightly builds are FAST! I am waiting for the final product here... wow.

I had that same setup before and it was great but didnt like how much it used to over heat. I then switched to trinity alpha 23 and Ive gotten much better battery with about 3 hours onscreen time and 19 hours overall. Now that I hear about alpha 43 I might just switch to that in a few

Is jellybean better for battery life ?

I am able to get 5 hours of screen on of battery life on ICS if I underclock to 800Mhz..But ive read jellybean is quicker but does it improve battery life ?

5? What do you do? I can easily get 12-13 with 20-30% remaining.

sorry I meant screen on time

In my limited experience over the last 48 hours, the battery life seems as good or better than ICS.
Not a huge difference though. Yet.

If u run aokp cm9 based with power savings (kill data when screen is off) under volt heavily you will lose 1% an hour idle. I have NEVER seen that on any other ROM...especially jelly bean ROMs. And jelly bean lags a while lot more than ICS regardless of clock speeds.

I lose 0% after three hours on idle during sammy's kernel and stock rom..But the issue comes when I begin browsing.
I constantly get 5 hours of on screen time with 800Mhz underclock - to me it's the best setting for battery life.

What sort of battery do you lot get on 4.2.2 (AOSP)

AOSP isn't as good as stock for battery life (a shame, but fair enough) - but how good have you guys managed to get it? What kernels, roms and tweaks are you running and what do you get as a result?
As a baseline I get about 4 hours screen on time with CM 10.1 as-is (no kernel changes or anything like that).

I've been getting about 16-18 hours with roughly 4 and a half hours of screen on time with slim ROM and redpill kernel

SentinelROM has been getting very good results in terms of battery life. Some guy got 7hrs screen on, and I got 6hrs with a little battery left over.

Beats me why people would want to flash a ROM with less features and less battery life..
Sent from my GT-N7100 using Tapatalk 2

Maybe because Touchwiz is laggy and ugly?
Anyway, the problem isn't the screen on time, but the total battery life. In standby, Note 2 with AOSP roms seems to have some processes on that totally eat the battery.
In my case, i switched back to Touchwiz. I've definitely want a 2-day battery life, and with AOSP is still not possible, unless you don't use the phone.

Battery Life is really good when the phone sleeps but I didn't note a better consumption when using my phone.

Because AOSP roms are beautiful and faster!! And you can get the last of Android, months before Samsung wants to release it.

I would agree with that comment back then with the galaxy s1, tw was really laggy.
But this day and age, the lag difference between tw and asop is minimal.
Just thought that ASOP doesn't really make sense...

I'm on Android 4.2.2 for a few months and we won't have official Samsung FW until end of June... So there IS a difference!

Sometimes i thought my galaxy s1 was faster on cm10.1 than my note 2 on TW rom. I'm not joking

Totally agree. Just get in the Phone app or the contacts or SMS app and then compare it to aosp. Beside its far more polished and responsive. And you also have 4.2.2 waaaay before Sammy decides to release it!

Because on 4.2.2 I can use dashclock on my touchscreen, I can have easily accessible quicksettings which don't take up space in my notification drawer, I can turn off the backlight for the hardware buttons and have a navbar with far more functionality, with paranoid android I can have the navbar and status bar change colour to match the app (which will also reduce status bar burn in), with rootbox/aokp I can have the status bar hide away until I either swipe it down myself or get a notification, and my phone still lasts me an entire day of my usage. I don't lose any features I didn't use in the first place, so it'd be silly not to be on AOSP in my case.

Although CM's battery file has never been as good as stock' due to high android_system usage, it shouldn't be %44 in just 4 hours.
Install "Better Battery Stats" and see what is keeping your cpu awake.

At 43% now after 7h 29m.
Screen 37.99%
Android os 25.61%
Chrome 6.26%
Google backup transport 4.99%
Media server 3.84%
So where is my problem?

Don't expect more with aosp/cm roms in terms of battery performance. I've tried various roms from carbon, Slim Bean to sentinel with all three kernels from Redpill, uneak and the stock kernel. I even tried to Greenify and I had almost no partial wake locks, and the most I could get out of it was 5hours screen time and maximum 12hours between each charge cycle. They still need a lot more. At the moment I've switched back to a stock based ROM giving me upto 7hours screen time on auto brightness and 24hours between charge cycle. And although, I lose all those exciting features from aosp, battery life is one of the most important factor why I got it in the first place.

If you compare cpu usage of 'system_server' process in CM based roms and Stock, you'll see there is a huge difference.

[Q] Increasing Battery Life of CM10.1

Hey guys...
I'm currently trying out CM10.1 and I'm loving it.
As its better than any other cm based roms like PA, Pac man etc
I'm really disappointed from the battery life, it drains so quickly
I tried NEAK kernel but it didn't help, can some one help me out to get good battery life out of cm10.1?
Thanks in advance.

I use carbon rom and neak kernel and i get about 22 hours with 5 hours screen on that's the best aosp rom i have seen for the battery
Sent from my GT-N7100 using xda app-developers app

I got 10 hours on average(Which i guess is ok)when I was on Cm 10.1. I used to set CPU to about 400 MHz when I was just listening to music but 200mhz when it was sleep. It was a hassle to do but it did help.
Sent from my GT-N7100 using xda app-developers app

Im curious aswell. Im running cleanrom ace 4.9 and im getting around 1day 12hrs with 4 hours screen on. I want to move away from stock again but can never get more than 16 17 hours on aosp.

I heard devil kernel is pretty good with battery on AOSP, also try downloading greenify from the play store. It take apps that constantly run in the background that aren't in use and hibernates them. I'm a heavy user of youtube and radios and I get around 20-24 hrs. But on light days I get over a day. I'm currently using ProBAM

The most I could ever get was always 5hours screen time and thats after using Greenify, Droid wall and uv/uc with slimbean, carbon and pa. I've heard of some people getting upto 7 hours on aosp but they never seem to share the setup, most likely in airplane mode though. Ultimately battery life was always an important factor for me so I reverted back to tw roms. Sad.
