Garmin claims up to 320 hours of activity tracking with its new solar smartwatch.
The Apple Watch Ultra 4 can run for up to 84 hours between charges, but Garmin’s new $899.99 Enduro 4 can track your activities for up to 320 hours or function as a basic smartwatch for up to 90 days. Instead of squeezing in a massive battery, the Enduro 4’s sapphire-protected touchscreen has an integrated solar panel so extending its battery life requires daily sun exposure.
