For the convenience of Xiaomi Smart Doorbell 3 users, the device's battery level is directly displayed in the Mi Home app. The principle of power display in the app involves converting the doorbell's battery voltage into either the number of battery cells or a percentage, which is then reflected in the app interface. This allows users to easily monitor the battery status of their doorbell and take appropriate action when needed.
For your reference, below are the reasons that Why is the battery level not updated in the APP after the Xiaomi Smart Doorbell 3 is charged:
1. The power display is not real-time, the doorbell needs to be online, the data is transmitted to the cloud, and the cloud is fed back to the mobile APP for display;
2. If the network is abnormal and the power consumption is abnormal in a short period of time, the APP cannot accurately obtain the synchronization data of the doorbell;
3. After the charging is completed, you can press the doorbell several times. After the doorbell is connected to the Internet and transmits the battery information to the cloud, refresh the Mi Home APP, and the APP can quickly display the battery level of the doorbell.
