My device is running the latest nightly of Cm 10.1 and TWRP. Bootloader obviously unlocked.
On top of CM10.1 I also flashed Crossbreeder
On top of all that I used this script here to odex CM 10.1
I have screen on auto brightness, MSM-DCVS governor, max frequency 1512 MHz, and DEADLINE I/O.
I woke up this morning at 7am and now at 3:30pm i just hit 85% battery life. This thing ZIPS too, no lag. That is with fairly heavy usage as well.
Just wanted to post this in case anyone wanted better than stock battery life on an aftermarket ROM.
