Following the Apple Watch event, which included the introduction of the rugged Apple Watch Ultra, Garmin said it measures battery life in months and not hours.
Compared to the Apple Watch Ultra, the Enduro 2 can last for months. The Apple Watch Ultra has the longest battery life of any Apple Watch to date, with Apple promising up to 36 hours of normal use and up to 60 hours with watchOS 9's new Low Power Mode.
The Endor 2 is advertised as having up to 150 hours of battery life in gps mode with solar charging and up to 34 days of battery life in smartwatch mode. The Apple Watch Ultra has a display that can reach a peak brightness of 2,000 nits, which is the highest in an Apple Watch.
The Apple Watch Ultra has a wide range of advanced sensors, including the ability to take an electrocardiogram (ECG), measure blood oxygen level, and alert for high and low heart rates.
The Apple Watch Ultra is available in a 49mm case and costs $899. The Apple Watch Ultra will be available for pre-order on Friday, September 23, and will be shipped the following day.
