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…
Reading reviews on Amazon, it makes it sound like it's not the best on privacy.
