I charge it when showering, preparing to go to bed, and during working hours when I know I won’t get up for at least 30 minutes.

​

then needs about 1.5 to get a full charge.

That’s the neat part, you don’t have to full charge it. The recent watches since Series 7 has this quick charge and you should be able to charge it to 80-90% quickly. So the idea is basically to shortly top it up but often.

Up to Steam Deck 2, maybe afterwards they might make Steam Deck 2 Episode 1, but it will definitely stopped at Steam Deck 2 Episode 2

Yeah, my Steam Deck just got RMA’d a while ago and in my experience heavy games that sucks ~25W overall usage (the number includes screen usage etc) will suck ~1% every minute so should be closer to 90-100 minutes
