I am selling a Xiaomi Band 7 body and two replacement bands as a set. I have been using the body for about two years. I'm not sure about the battery life, but the last 1% of charging from 99% to 100% now takes a long time. The charging cable also seems to have a loose Type-A connector, so it's become a bit picky about chargers, but it can still charge. I'm selling it at a low price, so thank you for your consideration. Please use the Zepp Life app. Charging cable included.
