The last two nights I've gone to sleep with my battery being 80% or more. I've woken up to a dead phone. I am not powering down the phone, just leaving it idle. My friend with the same phone says he loses 10% a night while idle and he leaves everything on. I have Wifi/Bluetooth off. I suspected "Wifi Fixer" initially and I've uninstalled it, but it doesn't seem to help. I've uninstalled any questionable apps, killed services, but it doesn't help. My daytime use is bad, but I kind of expect it. I charge it at night and once in the middle of the day and I'm fine. But I need it to last 12+ hours while idle. What gives?
