Most of us use this device on A/C, so to prevent the battery from unnecessarily wearing out, [ the battery inside should be disconnected or fully charged ] and then bypassed.
Request: The fan’s adaptive behavior should be applied to A/C only mode instead of only being applied during battery mode.
Currently the fan speeds will only be adaptive when in battery mode. In A/C mode it spins at full speed all the time.
Please @Philips_Support_N response to this very important question - why fan spinning faster when AC is connected? I think reason is that the brightness is also increasing but I need low fan noise not brighter screen. The only solution right now is to switch to battery
it is also a matter or proximity. some people have their units fairly close to their heads (right above the couch for example), hence it does become fairly audible.
I am still routing for unified fan performance (ac or battery) as well as an option to limit / turn off battery charging while plugged in
