best rom cm9 / cm10 / cm11? battery friendly?
I have this galaxy w which I had the stock rom with gingerbread.
I was searching for a custom rom for the phone and saw that there were cm9 cm10 and cm11.
I installed the new cm11 by arco68 but I'm having problems with the battery with greenify already installed.
During the night when I was asleep in 3 hours used 10% of my battery.
I'm new in roms and android development, so can anyone help me and tell me the differences between each cm version?
Any version is more lighter with the battery?
What can I do improve the battery use?
Thanks in advance
