You can save battery life by turning on Low Power Mode. Doing so turns off Always On Display, background heart rate and blood oxygen measurements, and heart rate notifications. Other notifications may be delayed, emergency alerts may not arrive, and certain cellular and Wi-Fi connections are limited. Cellular is turned off until you require it—when you stream music or send a message, for example.
Note: Low Power Mode will be turned off when the battery is charged to 80%.

Press the side button to open Control Center.
Tap the battery percentage, then turn on Low Power Mode.

You can tap Turn On For, then choose On for 1 Day, On for 2 Days, or On for 3 Days.
Tip: If you have battery-powered devices such as AirPods connected to your AppleWatch through Bluetooth, tap the battery percentage in ControlCenter, then turn the DigitalCrown to see the remaining charge for your headphones.
When the battery level drops to 10 percent or lower, your AppleWatch alerts you and gives you the opportunity to enter Low Power Mode.
