It supports multi-band GPS on L1 and L5. The Ultra includes a new, orange-colored “Action” button, which can be mapped to different functions, as well as an emergency siren feature. The Apple Watch Ultra contains a battery 76% larger than that of the Series 8, which Apple rated at 36 hours of usage without using power saving modes (as opposed to Apple's rating of 18 hours on the main line). A power saving mode which reduces the amount of heart rate readings and GPS polling can extend its battery life to around 60 hours. All Apple Watch Ultra models include cellular connectivity. The Apple Watch Ultra has a water temperature sensor, and carries WR100 and EN13319 certification. Apple rates the device for diving to depths of up to 40 m; a new “Depth” app is included for displaying depth and water temperature information, while Apple partnered with Oceanic Worldwide to release the subscription-based “Oceanic Plus” app for more advanced dive computer functionality.
