If you are considering buying an Apple Watch, you should know some information about GPS. Apple has confirmed that the Apple Watch Ultra, Apple Watch Series 8, and Apple Watch SE (2nd generation) will not utilize the GPS signal on the iPhone even if the iPhone is nearby. All three Apple Watch models have built-in GPS, while older models still use the iPhone’s GPS model.
Apple officials recently wrote in the official update log:
Apple Watch Ultra, Apple Watch Series 8, and Apple Watch SE (2nd generation) use the built-in Apple Watch GPS even when your iPhone is nearby. to extend battery life, older Apple Watch models use the GPS on your iPhone when it’s available.
While older Apple Watch models extended battery life by using the GPS on the iPhone, Apple has more confidence in the battery life of the three new Apple Watches mentioned above. Apple also introduced a low-power mode in watchOS 9, which can extend battery life with GPS and heart rate data disabled.
