Short battery life

No matter h ow skeptical we were from the very beginning the Apple Watch is everywhere now. You see them on the wrists of all kinds of people-not just tech nerds. It is officially a thing.

The display is actually very pretty and makes the Watch easier to use

Battery life has diminished and some of the coolest features aren't available yet

Sure, Apple Watch is a huge success, outselling all rivals, but there are still a lot of fence-sitters not sure if it's really a worthwhile addition to their Apple ecosystem. And not everyone is a watch person. If this sounds like you, it's time to get off the fence.

Apple takes unjustified heat for iterating on a product year after year. By not tossing out the whole platform and design, however, the company has created a game-changer with the Apple Watch Series 4.

If you already have an Apple Watch, should you upgrade That depends. If you own a Series 3, I wouldn't rush to trade it in unless you use it to make calls all the time or see the upcoming ECG feature as a must-have feature.

Large screen; Good call quality; ECG capability; Fall detection; WatchOS 5 brings numerous improvements; Stylish
