Run Apps and Respond Faster Than the Apple Watch 3
The Apple Watch 4 comes with a new S4 chip inside that is capable of running twice as fast as the Apple Watch 3, and it includes the same 18 hour all-day battery life as the older model.
The upgrade to the Apple Watch 3 made apps usable and greatly improved using Siri on the Apple Watch, and this should continue the trend with better performance that allows you to actually do more with your Apple Watch.
Tack on the watchOS 5 upgrades and it is easier to use the Apple Watch and leave your iPhone in your pocket, or at home with the LTE model.
