Maybe it has been covered already but my S7 is back to the same battery life as before WatchOS 10. I usualy take it off the charger at night, sleep with it and then use it all day. So around 23-24h of usage and it is around 35-40% battery left when I put it on the charger now! Used mainly for notifications etc so nothing intense.
Is it just me or did a few days with 10.1.1 fix it? Alittle scared to update to 10.2 but I’m looking forward to swiping quickly to snoopy!
I charge my s7 fully up before bed, sleep with it on and use it all day, after 23h it goes back on the charger with around 30% left. No workouts or anything else like active use of cellular or any apps. So if you will use the watch more actively it might not be enough but for me it is great!
