The Xiaomi Watch 2 supports the Always-on display (AOD). When enabled, the watch will switch to AOD mode after the screen times out automatically. You can activate this feature by navigating to [Settings] >> [Display] >> [Always-on display].
Here are some important points you need to know:
1. Enabling AOD will reduce the battery life of the watch. It is recommended to consider your usage needs before turning it on;
2. In the off-screen state, you can touch the screen to wake it up;
3. Enabling AOD will disable the raise to wake feature;
4. If the watch is removed or covered manually, the screen will dim after 5 seconds when it is on. Night detection during sleep will also dim the screen.
