Waited for iPad to charge fully when powered off to mostly remove battery charging impact. Used Garmin GLO and house WiFi access point(2.4GHz) for testing.
Highest power user was the backlight, tripling the idle power when changed from minimum to maximum. Next highest was when CPU was at high load(moving screen quickly). WiFi and BT used minimal power except during large transfers(some of that was probably CPU not directly WiFi).
