Battery life most appealing


After wearing for about a month noticed no sleep data, following week or two noticed heart rate could not be detected, then noticed steps counted were not what I had managed to do (I had started getting annoyed that it was not working effectively).
I contacted the seller (little to no help), contacted Xiaomi - and they could not help as "not purchased through an authorised seller" - beware of this small inconvenience. I had taken out some break down cover insurance on its performance - but those hoops just too tedious to leap through.
Best thing - battery life and its visible.

Purchased in May 2020 at eBay seller for $57.65.
