Extending the battery life
Some functions on your smartwatch use a lot of power and therefore significantly reduce the battery life. You can reduce the power consumption by turning on low power mode.

Slide your finger downwards starting from the top of the screen.
Step 2 of 2
Press the low power mode icon.
When you turn on low power mode, most smartwatch functions are turned off.
