Q: Is this watch compatible with iPhone 15
A: The third-generation Apple Watch SE requires an iPhone 11 or later with iOS 26 or later for full compatibility. While older iPhones might pair, you will not be able to use many of the new features, such as the updated watchOS 26, which is required for the new device to function properly.

Battery Life
My biggest worry before purchasing was that the battery wouldn’t last long especially because I knew I would be using the gps a lot for running. But it exceeded expectations and lasted way longer than I thought it would. Easily lasts the whole day with a great amount of usage.
