Why is the battery life on the Xiaomi Watch 5 short?

If the battery life on the Xiaomi Watch 5 is short, please refer to the following information:
1. High screen brightness increases power consumption and can result in shorter battery life.
2. When the Always-on display (AOD) feature is enabled, the screen remains active and drains the battery more quickly.
3. Continuous health monitoring functions, such as heart rate or SpO₂ tracking, consume additional power during operation.
4. Watch faces with complex animations or effects require more energy and can shorten the battery runtime.
5. Usage environments with weak signals, low temperatures, or frequent GPS usage can lead to higher power consumption.
6. System updates and background app activities will temporarily increase power usage after installation or syncing.
