I have a Series 4, and I normally have "Wake Screen on Wrist Raise" turned off except for 30-40 minutes per day when I'm exercising. I'll also sometime turn that on if I'm using a timer that I want to be able to see at a glance.

I charge it in the evening, when I'm relaxing reading or watching TV. I can usually get it to 100% before I go to bed. If not, I'll put it on the first time I wake up to urinate that night.

By the time it gets to the next evening, it is usually at 55-65%.

If I forget to charge it in the evening (e.g, I fall asleep while reading or watching TV), it would probably make it fine to the next evening. In those cases, though, I'll stick it on the charger while I shower and have breakfast. That's more than enough to ensure no problem getting to the evening.

I charge while I have my coffee, take a shower, and get dressed, in the morning. Wake up, run Breath and then put the watch to charge until I get dressed.

I charge when sat at my desk, usually in the morning.
