I checked battery drainage of my Aigo. Had flashed Aigo using ExPLIT's instructions. 1. Without touching BIOS: Airplane mode, Android on: 100->39 %, 5.2 %/h Airplane mode, Android off: 100->19 %, 5.3 %/h 2. BIOS, Max Battery: Airplane mode, Android on: 100->30 %, 5.4 %/h Airplane mode, Android off: 100->61 %, 5.2 %/h Looks like BIOS setting does not have any effect, nor Android support.
