As for now, i get 21hr before the battery died, screen on 1hr 52min, betterbatterystat says wake lock is download manager (4min 12sec), in Battery Usage, Android OS is on the top hooking 84% and getting 21hr 43min Keep awake! But funny thing is inside the battery usage graph, i don't see any funny random awake. so what could really be draining my battery?
As i said, it was on the WIUI which is a ROM based off MIUI which is based off CM9. Idk what MIUI/ the guy WIUI are doing, but they somehow tweaked CM9 to offer amazing battery life.
I'm back to CM9 since it's nightlies and battery life is better than before, i'm at 8 hours on battery and 36minutes of display time. Nothing close to what I was getting on WIUI/MIUI, but its better than it used to be. Standby is better but still not that great.
I might go back after they implement the HW codecs in their MIUI/WIUI build and just use an ICS launcher
CM9 is still awesome though, just wish battery was a bit better. It gets me through the day still.......I use anker 1900mah btw, but still nothing compared to samsungs 2000mah. I'd say the anker is really around 1800mah but its good for only $20 for 2 + charger
