Re: Increased Idle Battery Drain
Higher overall idle current was isolated to an i2c 2c power management issue, this is resolved with the patches that just went in. We're idling at 3.5mA, which is LOWER than 25R, so yay for us
The proximity sensor issue is harder to reproduce but it's confirmed, we are working on this now
