Does anyone know how much power this draws when idle? With a 49WH battery and assuming 5W idle (which is what you can get the 4k series ryzen mobile down to on windows on a good day), that's just under 10 hours. Anyone have any tighter numbers? I would seriously consider buying this if I could actually expect 10 hours battery pretty consistently.
