I'm getting the feeling white icons are causing high drain (not strange because you need multiple leds active to make that color)
Stock Rom + Abyssnote 3.7 Kernel
CPU UV 1600 MHz 1350mv max - 100 825mv min
noLED on with:
-grey clock Jumping arround the screen (quite big, bit bigger then medium icons but its only grey tekst (build in clock))
-Call missed dot in upper left corner
-noLED Weather on jumping arround the screen.
I currently have a drain of 1% every 6-7 min.
With only a Call missed dot in upper left corner and a SMS icon it seemed to be less. But i will test that tonight.
But this kind of drain is to much over night. It will your battery very fast: 9-10% every hour. And thats with only one icon with white in it (its mostly white with blue and a bit of yellow because if the weather. It has some white teskt next to it with the city name and temperature) and some tekst on the screen from the weather info and the grey clock.
But i will try to do some extra testing so see what causes drain. I dont like to use timeouts but maybe i can minimize it by using other icons.
