If you aren't an iOS user, meanwhile, we recommend the $200 Fitbit Versa 2 . While it doesn't feature nearly as much in the way of apps as the Apple Watch, it offers an always-on display, accurate fitness tracking, and up to five days of battery life.

Always-on display; Excellent fitness tracking and heart rate monitoring accuracy; WatchOS 6 brings useful new apps; Smooth performance

Expensive; No built-in sleep tracking; Battery life remains the same

Apple Watch Series 5 has about 30% less battery life with always on display enabled. If I workout, I have to put my Apple Watch on the charger by early evening. There is very little difference in the Series 5 and Series4 with always on display disabled.

There's no question that the Apple Watch Series 5 is the absolute best smartwatch money can buy. It has an incredible screen, excellent app support, and the strongest set of sensors and features you'll find anywhere.

I upgraded from an Apple Watch Series 4. Partly I upgraded because I'd accidentally put some deep scratches in to the screen of the series 4 watch. I'd done it gardening - digging some holes for trees in stoney ground. The stones ( some granite rocks ) scratched the Apple Watch's Ion-X glass.

Solid build quality and design; Always-on display mode doesn't impact 18-hour battery life; Always-on display mode can be disabled; Accurate internal sensors (heart rate; GPS; etc); On-Watch app store is easy to use and useful; Cycle tracking is thorough and discrete with watchOS app

Activity Trends isn't as detailed as it should be; Still no native sleep tracking; Not many Watch-only apps yet; Only works with iOS devices; Expensive; No third-party watch faces

As Apple introduces its new Watch Series 5, the company is discontinuing the similar Series 4 and lowering the price of 2017's Series 3. The price difference between the Series 3 and Series 5 is quite large; with the devices starting at $319 and $649 respectively, or $469 and $799 if you want the...
