S6 gives me 30 hours
Charged 60-90 minutes per day. Usually lives around 20-80% never hits zero, seldom hits 100%
Used for daily workouts for maybe an hour, sleep tracking, and basic tasks. Often used to pay for things, find quick directions, or do maths.
If my s6 with 94% battery life remaining can do this comfortably, basically any ‘current’ watch will be more than capable.
That 30 hour lifespan really is that sweet sport for daily use without having to think too hard about it.
It just works.
