Garmin Enduro 4 — an Ultra-Rugged Sports Smartwatch With Up to 90 Days of Battery Life

Garmin has unveiled the next generation of its Enduro sports smartwatch. Battery life is the main feature of the Enduro 4. With normal use, the device can operate for up to 36 days without recharging, or up to 90 days with sufficient sunlight. When recording a GPS activity, battery life depends on the mode—up to 120 hours of normal use and up to 320 hours using solar energy. Garmin always calculates its watches’ battery-life figures based on an ideal standard: 3 hours a day at an illumination level of 50,000 lux, so actual battery life will depend on how many hours the device is exposed to direct sunlight.

The Garmin Enduro 4 features a low-power 1.4-inch MIP display with a resolution of 280 x 280 pixels. The display is protected by Power Sapphire glass with a solar panel. It has a stated water-resistance rating of 5 ATM. The case is made of fiber-reinforced polymer and complemented by a titanium bezel. The watch is fairly large, measuring 51 x 51 x 15.7 mm and weighing 66 g.

The watch supports more than 100 workout modes. It adds grade-adjusted pace targets, new Stamina Zones and Stamina Curve metrics, while the Garmin Epic feature lets users combine multiple activities spanning days or weeks into a single story. The new Perspective View mode shows more route details.

Storage has increased from 32 to 64 GB, while RAM has increased by 50% compared with the Enduro 3. It includes NFC for contactless payments through Garmin Pay, GPS, and an LED flashlight with white and red light. Health features include an optical heart-rate sensor, an SpO2 blood oxygen saturation monitoring system, a skin-temperature sensor, and an ECG recording feature.

Sales of the Garmin Enduro 4 will begin on October 9, 2026, at a price of $900. The watch comes with a ComfortFit fabric band featuring a QuickFit attachment—a first for devices in the Enduro lineup.
