Practical Tips to Extend Battery Life

Turning off always-on display and setting the screen to light up only on wrist raise significantly reduces drain. Clean up unnecessary app notifications, and only enable GPS when you actually need to track a workout. Setting brightness to auto-adjust also helps conserve battery.

Frequently Asked Questions

How much battery does always-on display use?

Enabling always-on display adds about 15% of your battery capacity in extra drain, significantly reducing overall battery life. Turning it off and only lighting the screen on wrist raise saves a lot of power.

How does GPS tracking affect battery?

GPS is one of the most power-hungry features on a smartwatch, using about 3mAh per minute. A 1-hour run tracked with GPS can consume about 180mAh, a significant chunk of a typical battery.

How can I extend battery life?

Turning off always-on display, reducing unnecessary notifications, and only using GPS when needed are the most effective steps. Lowering screen brightness also helps.
