Why does the Xiaomi Smart Band 10 record a high number of steps without any actual walking?

For your reference, here are the reasons for a high number of steps recorded on the Xiaomi Smart Band 10 without any actual walking:
1. The Mi Fitness APP supports multi-device data merging. If multiple devices (including phones connected to the band, phones logged into the same Xiaomi Account, or multiple bands and wearable devices linked to the same account) are used under one Xiaomi Account, the step count and calorie data will be combined;
2. If multiple people use the same Xiaomi Account, step count and calorie data can appear significantly higher than actual. To ensure accuracy, it’s recommended to use one Xiaomi Account per person and avoid account sharing.
