Summary
- Garmin Enduro 4 boasts up to 320 hours of battery life.
- It utilizes a memory-in-pixel display for solar charging.
- The watch offers advanced health tracking features like stamina zones.

Garmin has launched the Enduro 4, a new smartwatch designed for extreme endurance with an impressive battery life. The device promises up to 320 hours of operation when its activity mode is enabled and conditions are sunny, a substantial leap beyond the Apple Watch Ultra 4's capabilities.
This remarkable battery performance is attributed to Garmin's new software power modes and a built-in memory-in-pixel (MIP) display, which allows for solar charging. While not as luxuriously built as Garmin's Fenix 9 Pro, the Enduro 4 features a durable fiber-reinforced polymer shell and a scratch-resistant sapphire lens. It also boasts 50% more RAM than previous models for smoother navigation and includes 64GB of onboard storage.
The Enduro 4 integrates comprehensive health and fitness tracking, mirroring features found in the Fenix 9 Pro. Users can monitor stamina zones and analyze endurance trends with a stamina curve. The watch also supports Garmin Epic, a new system for tracking extended activities. Priced at $900, the Enduro 4 focuses on delivering exceptional battery life for long-duration adventures.
