Why does the Xiaomi Watch 2 vibrate for a new message notification but not light up the screen?

When the Xiaomi Watch 2 vibrates for a new message notification but does not light up the screen, it's part of the watch's optimized notification strategy.
The reasons are as follows:
1. Optimized power consumption: Lighting up the screen every time a message arrives can consume additional battery power. By vibrating without lighting up the screen, the watch conserves battery life, allowing you to use it for longer periods between charges;
2. Minimized disruption: Constantly lighting up the screen for notifications can be disruptive, especially in environments where discretion is important. The vibration notification ensures you are aware of incoming messages while minimizing interruptions;
3. Control conveniently: You can control over when to view messages. If you receive a notification and want to check it immediately, simply raise your wrist or tap the screen to wake it up. This way, you can manage messages at your convenience.
