Garmin Debuts Enduro 4 With Up to 320 Hours of Battery Life
The Enduro 4 smartwatch packs 64GB of storage, a sapphire lens and 10ATM water resistance, priced at $900.
Garmin has announced the Enduro 4, a new smartwatch that delivers up to 320 hours of battery life in activity mode under sunny conditions. The company credits the extended runtime to new software power modes and the watch's memory-in-pixel (MIP) display.
The Enduro 4 carries 64GB of onboard storage and 50% more RAM than past Garmin models. It also features a scratch-resistant sapphire lens and 10ATM water resistance. The watch is priced at $900.
On the health and fitness side, the Enduro 4 supports the same tracking features as the Garmin Fenix 9 Pro, including stamina zones, a stamina curve and Garmin Epic, which the company describes as a new way to track and summarize multiple types of activities over an extended period.
How it compares
The Enduro 4's MIP display is not as bright and vivid as the OLED panel on the Fenix 9 Pro, and its fiber-reinforced polymer shell is not as luxurious as the all-titanium finish of the Pro. The scratch-resistant sapphire lens and 10ATM water resistance were already offered on the Enduro 3.
In October 2025, Apple significantly extended the battery life of its premium smartwatches with the release of the Apple Watch Ultra 4, which manages over two days of battery life, according to Gizmodo.
