I sold my watch because I was so annoyed by the bad battery life.
I expect a watch to run for a couple of days at least. Charging it while taking a shower must be sufficient. And I do not shower for half an hour.
As long as the Apple Watch is not able to do that, it’s a no-go for me.
“A couple of days” seems like the worst of both worlds - it needs to be charged often, but not on a fixed schedule, so you have to keep tabs on the battery and plan ahead.
Personally I just have a charger on my night stand and charge it every night alongside my phone. It’s an easy routine and I don’t want to sleep with a watch on anyway (smart or not) since when I do I eventually get a rash on my wrist.
For those who want to do sleep tracking, they need to speed up charging so that the “charging while I take a shower” works for those of us who take shorter showers
Just thought I’d mention that if you are getting a rash when sleeping with the watch, you need to start cleaning the bottom of the watch or clean it better. I wipe mine down with an alcohol wipe once a day, and use my nails to get the wipe into the crevices where dirt and sweat might be building up. Hope that helps you!
