You just plug in your devices when you go to sleep. I don't get why that is difficult.

That does diminish the sleep tracking benefits. It's still doable, but now it becomes "remember to charge your watch at least an hour before bedtime" which isn't as simple of a routine.

If you’re using the sleep tracking features, the watch will remind you if it thinks it won’t have the juice to get through the night.

15 mins of charging during a shower is usually all I do for my S9

Hmm okay I haven't though about that.

That was fine until I started using it for sleep tracking. Now it’s kinda hard. I put it on the charger when I’m taking a shower and having dinner still it’s not super convenient.
