The Xiaomi Smart Band 9 Active features the standing reminder.
For your reference, here are more details about this feature:
1. After turning on the standing reminder switch, when it detects that there is no activity for 50 minutes in each natural hour, the band will vibrate at the 50th minute and remind you to move up. If you recognize standing and walking within 10 minutes after the reminder, a finished standing reminder will pop up;
2. Sitting for a long time and not moving can lead to many health problems. It is recommended to stand up and move once every hour when wearing the band. Standing up regularly is a convenient way to reduce sedentary behavior and increase energy consumption;
3. You can only turn on the standing reminder, set the start and end time, and set the lunch break to do not disturb in the Mi Fitness APP. To turn on the standing reminder in the Mi Fitness APP, go to [Device] >> [Fitness and health] >> [Standing] >> turn on/off >> set time period.
