Is now a good time to upgrade your smartwatch for better battery life?
Garmin has released the Enduro 4, a 51mm smartwatch designed for extended outdoor use. The device, which is now available, features solar-charging technology that pushes battery life significantly beyond standard non-solar metrics.
Why it matters
This release represents a strategic update in Garmin's wearable lineup as the company aims to outperform the Fenix 9 Pro Solar. It prioritizes power efficiency for long-duration activities through hardware-integrated solar cells.
The Enduro 4 features a 1.4-inch, 280 x 280 pixel MiP display housed in a 51mm by 15.7mm frame. It offers 36 days of battery life, extending to 90 days with solar augmentation and 144 hours during continuous workout tracking.
The players
Garmin
A developer of wearable technology, navigation hardware, and fitness tracking software focused on performance monitoring.
The details
The device achieves its power metrics by integrating solar cells into the Power Sapphire display cover, a durable material that allows light to charge the battery while the watch is in use. This system complements the Memory-in-Pixel (MiP) display, a low-power screen technology that retains images without constant refreshing. For extreme duration, users can leverage dedicated expedition or power-saver modes to reach theoretically unlimited battery life.

The Tech Race
The Enduro 4 is positioned to exceed the performance metrics of the Fenix 9 Pro Solar by optimizing power draw and solar harvesting. This release continues the industry-wide focus on increasing battery autonomy for multisport wearables.
Users can expect the device to significantly extend the time between charges, particularly for hikers and endurance athletes who spend extended periods in direct sunlight. The 51mm titanium build indicates this is a large-format watch intended for users who prioritize longevity over a compact wrist footprint.
The takeaway
The Enduro 4 prioritizes long-form endurance tracking by integrating solar hardware into a larger chassis. Prospective users should monitor official regional retail availability to confirm launch pricing and model variants.
