> I don't want any other feature except a battery that can make it a full day. I thought the Series 7 could make it a full day? My wife has a S6 and makes it about 36 hours with her normal usage (which is admittedly quite light). For me, it's not a watch if it has to be charged every day or two. I need 4+ days of battery life so that I don't have to bring another charger on every overnight/weekend trip.
My Mi Band 6 from Xiaomi easily lives ~30 days on one charge if used less (eg. no constant heart tracking, no PAI) and ~7 days with all tracking enabled (sleep, oxygen, heart rate, 1-2 workouts a day). With a third party app instead of Xiaomi "Mi Fit", I belive also all the data stays with me. That makes me wonder - what does Apple Watch do that Mi Band doesn't that makes the time on battery so much different? I gues…
