Apple Watch Series 4 Review: Bigger Screen and a Whole Lot More
After two weeks with my Apple Watch Series 4 I'm still glad I bought it, and I was upgrading from the very capable Apple Watch Series 3. The big thing for me right now is the larger and brighter display. The stronger haptic feedback and louder speaker are nice plusses, too.
Bigger and brighter watch face; new heart rate sensors; better speaker; old watchbands still fit
Auto-sensing for ending some workouts is too aggressive; LTE available only on stainless steel models; settings like Theater Mode still don't mirror between iPhone and Apple Watch; battery life not good enough for back country use
