Does the Xiaomi Smart Band 8 support mobile phone alarm reminders and how to turn off and delete the alarms synchronized with MIUI phones?

This feature is only available on Xiaomi phones and currently needs to be set up in the Mi Fitness APP. To use this feature, you need to keep the phone and the band connected. When the phone alarm rings, the band will vibrate to remind you synchronously.
In a connected state, after turning on the alarm reminder, the alarm will be triggered on both the phone and the band at the same time. You can use the band to turn off and later on the alarm reminder. The band cannot change the phone alarm information. If you need to change it, you need to modify it on the phone.
In a disconnected state, the alarm on the phone cannot be synchronized to the band when it is triggered. You need to handle it on the phone.
You can synchronize the alarm by opening the [Mi Fitness] APP >> [Device] >> [Alarm] >> [Sync alarms from phone]. It also supports deleting the synchronized alarm.
