Q: Why does the LCD display on the IBBQ-4T show full but the app says 44%?

A: The thermometer only has three Power displays:
① When the battery is lower than 20%, the screen shows LOW.
② When the battery is up to 20%, the screen shows 100%.
③When the battery is charging, the screen shows the charging status. Therefore, the power showed in the app is the correct one.
