Mint can't synchronize the watch heat.

When using Apple Watch to record sleep for the first time, we need to set the bedtime and wake-up time. Generally speaking, adults need to sleep for 7-8 hours every night, and the health app will set 8 hours of sleep for us by default. Just slide the slider to set the time to sleep and get up. After the setting is completed, Apple Watch will remind us to go to sleep on the eve of the arrival of time, and turn off the screen of Apple Watch during sleep, thus controlling the power.
