OK, I ran a couple of new tests today to gather some more information about the battery usage in the TabletKiosk eo.

Both tests had the same setup: Wifi switch in the off position, most background applications like antivirus, firewall, OneNote etc. off. Hard disk was set to turn off after 15 mins in the control panel and to never go into standby. Notebook Hardware Control was running and doing dynamic CPU switching. Both times are from disconnect until forced standby at 3%. System idle otherwise. The system had cooled down for both tests since I charged while the unit was in standby.

Test 1: Screen off the whole time: 2 hours 3 minutes. After the test I recharged again and tried to check the charge rate. For some reason I didn't get a log file, but the reading on the screen showed -11.34W after I switched the screen back on.

Test 2: Screen on the whole time at 100% brightness: 1 hour 21 minutes. NHC reported charge rates between -15W to -18.5W.
