I can confirm these observations, a great deal less power drain at idle. Still seeing the massive drain with screen on time, though. AIDA, top, lighthouse, nothing shows any crazy usage. I thought maybe it was doing something goofy with the GPU clock when web browsing and the like, so I stuck it at 100MHz for testing. Same results.

I don't really expect to get more than a day and a half total, but the screen on drain is very frustrating.

Still testing, still digging.

I do believe 100Hz timer is the right direction, though. Great work guys!
