After about 2 weeks of use , i decided to check the battery life info , because I have a feeling that this rom and kernel has the best battery life ever.
It's just amazing on my D802.
Use with battery : 71 hours 28 minutes
SOT : 4 hours 36 minutes
... and like i said , still 41% left !
Info : I set the phone on 0% screen brightness and on flight mode when I'm sleeping (about 7 hours a day)
I use the phone as on all other roms before ,and must say that I have to charge much less with this rom and kernel.
