How long smartwatch batteries really last

Every watch here is rated for 14 days or more in normal smartwatch use. The real figure depends on how you use it: an always-on display, frequent GPS workouts and music cut it a lot. Compare the GPS and always-on figures, not just the headline.

For the longest runtimes, look at simpler MIP screens and solar charging.

Frequently asked questions

Which type of smartwatch has the longest battery?

Watches with low-power MIP displays and simpler software, such as many Garmin, Coros and Amazfit models, last weeks. Bright AMOLED watches with apps usually last one to three days.

Does GPS drain a smartwatch battery?

Yes, more than anything else. GPS is measured in hours, not days, so check the GPS rows if you train often.

Will I get the battery life the maker quotes?

Treat it as a best case. Always-on display, lots of notifications and GPS workouts all cut it down, so a typical week is often shorter than the rating.
