Regarding sleep: the most important reason why these devices suck for tracking sleep is that you have to recharge them every 24h. That's either not being able to use them during the day for some period or do overnight charging.

It might be hard to imagine, but your charging habits will change.

I wear my watch 23/7. It charges in the morning when I’m in the shower.

Only after an extra sporty day with a lot of sports tracking will I need to let it charge an extra 30 minutes or so extra during that day.

I recharged my Pebbles while I was in the shower, since they usually took less than 15 minutes to top up after ~24 hours of usage. I've found my Apple Watch (it is an older model, though) to need too much time to recharge, however, so rather than building a different habit around it I recharge it overnight.

I tried for years, didn't work for me (Apple Watch 2). I mow have a Garmin Fenix 7 which lasts 18 days without recharge, buy has much more limited features (which is fine for me).

I suspect that's why AW sleep tracking isn't improved well as GP said.
