Why does my band (Amazfit Band 2) use up power so quickly?

Two most power-consuming items of Amazfit Band 2 are the motor vibration and the screen. It is normal to consume more power if the band vibrates many times or pushes many notifications. If you don't use the foregoing functions frequently, please perform the following operations. Fully charge the band and turn off the mobile phone Bluetooth and alarms that have been set on the band (if any), put it away for 24 hours without any operations (such as sliding and using any functions), and observe the power consumption. If the power consumption exceeds 5% (3% if your band hasn't turn on the bus pass service), give feedback and provide your Amazfit ID to us to help us analyze and locate the problem.
