Google’s Samsung Galaxy Watch 4

The Android wristwatch is available in two styles and four sizes, with prices beginning at £249 ($250) for the Watch 4 and £349 ($350) for the Watch 4 Classic (as tested). They are the successors to the £269 Watch Active 2 and £399 Watch 3.

How is it different?

It is noteworthy that the two designs have the same features, chips, and screen sizes, however, the stainless steel Classic includes Samsung’s jog-dial-like spinning bezel controller, but the regular aluminum Watch 4 has a touch-sensitive ring instead. 

The watches are smaller and have a little more flair than the previous ones. With its classic silicone strap, the 42mm Classic is incredibly pleasant to wear and does not make you sweat.

The AMOLED screen is fantastic: brilliant, pin-sharp, and always on if you want it to be. The screen is scratch-resistant Gorilla Glass DX+, and the watch is water-resistant to a depth of 50 meters, so it should last a long time.


Screen: 1.2in or 1.4in AMOLED (~467/455 ppi)

A power-saving option can increase the battery life by a few hours, while a “watch only” setting disables everything but the watch face, allowing it to survive for more than nine days. Using the included magnetic puck and a typical 2.4A USB power adapter, it takes 82 minutes to fully charge, with 70% completed in 50 minutes. There is no power adapter supplied.

Samsung has not specified the life expectancy for the Watch 4’s battery, although it does offer a one-year guarantee. For at least 500 full charge cycles, batteries in comparable devices generally keep at least 80% of their initial capacity.

Though it is a Google Wear OS watch, Samsung provides the majority of the apps and services. Google Maps and Google Pay are significant additions, but Google Assistant is not yet available.
