What's your experience with battery life?

My problem with this watch is the screen turn on without need to do "double tap" gesture. When I am riding my motorcycle, the watch stays on big part of time. It stays on with any vibrations, hand claps, etc.

only use for 2 app notifications, no pulse, no hr, no wrist gesture, 4 days android, 5 days ios.

My 2 yr and 3 months old Vivomove Style runs easily for 4 full days on a charge. That's with NO Pulse Ox active, but with with HR on, one or two activities per day (usually a 30-40 minutes walk or run and 30 minutes weights workout four days a week). I have gesture on only during a workout but all notifications enabled (email, text, weather and various apps). If I am not doing an activity, I prefer to tap on the screen to turn it on when I need it, rather than turning on every time I rotate and raise my wrist.

When the watch was new I was getting the 5 days advertised by Garmin. An important point, though, is that I never run the battery down every time I charge it. I do it once in a while just to check how the battery is doing. I usually charge the watch every other day, sometime every day, and I keep Pulse Ox on (it measures only during sleep anyway).

Li-Ion batteries, the kind used in the smartwatches and virtually  everywhere else with a rechargeable battery, have a longer lifespan (meaning they will maintain most of the their capacity at each charge for a longer time) if they are charged a little but more often than if they are charged from totally discharged or very low charge every few days.
