alt Hacker NewsI leave my apple watch on a charger for at most 15-20 minutes in the morning and that gets it from the 10-20% in the morning to about 80-90% which is enough to go the whole next 24 hours even with a 30 minute lunch walk and 2-3 hours of pickleball fitness tracking as well as having the always on display on.
Never once has this seemed like a problem or that I would want to wear my watch in the shower for some reason. It's shower plus getting dressed and brushing my teeth etc.
Apple Watch has never lasted the full night for me. I'm super happy with my Garmin Instinct 3. A full blown iOS device on my wrist was too stimulating anyways. I'll take charging once every ~25 days-ish over the color + capacitive touch screen.
The Garmin Instinct 3 is my favorite tech purchase I have made in a very very long time.
