I have been trying getting some numbers from `powerstat`, intrigued by danieldk's results of 0.1W consumption: I am getting 3.7W during this browsing session. That 0.1W must be related to the CPU only. The result from `powerstat` is aggregate (if I raise the display lightness to an uncomfortable level the consumption raises to 4.5W). I do not know how to only get the consumption of the CPU. Trying to check...
Edit: I am really not sure how to disaggregate consumption and find a number comparable to that 0.1W. Maybe, danieldk, you could provide instead the aggregate consumption - the total (not just CPU) average consumption of your system? And eertami? Just to get an idea.
I had a brief Linux/Windows excursion with a ThinkPad T14 Ryzen laptop. Three hours of video meetings was enough to drain most of the battery in Linux (worse power management, plus no hardware encoding/decoding in some video meeting apps). In Windows, it lasted a bit longer, but the battery would definitely be drained 50%, often more.
The ThinkPad was not a lemon. This seems like pretty normal drain if you look at people's experiences on the web.
Really? I feel like that's just having any 2021 laptop. I have a 13" Linux laptop with the i7-1185g. I'm not going to pretend it matches the performance/watt of an M1, but a few hours of video calling makes a completely negligible difference to battery life for me. 20% for a few hours of video calls just feels baseline.
I've never been in a situation where I needed to get back to a charger, and can happily go the whole day of development and meetings with charge left over to spare.
