Why is Amazfit Band 5 running out of battery power fast?

Amazfit Band 5 battery life is 15 days (assuming 30 minutes for automatically heart rate detection, 100 notifications, 30 wrist lifts, and 5 minutes of other operations every day. 30 minutes of running every three days)
The most power-consuming functions of the Amazfit Band 5 include motor vibration, GPS positioning and the light of the screen. If you often run for exercises, receive pushed messages frequently, use instant scalping band face, or set a much too long screen-on duration, then it's normal that your band runs out of battery power fast. If you don't use these functions often, fully charge your band, turn on Do Not Disturb mode, set the brightness of the band to the lowest level, turn off the Bluetooth, set your band to the default band face, and then observe the power consumption after placing it still for 24 hours. If the power consumption is over 2% please submit your feedback to help us analyze and locate the issue.
