An incredible smartwatch for Samsung phone users but a little underwhelming when it comes to battery life

The Wear OS-powered Galaxy Watch 4 acts as the perfect equivalent of an Apple Watch but for the Android ecosystem. However, although it's a great wearable that would fit just about anybody, the Galaxy Watch 4 fails to deliver in one key aspect that's ultimately the most important feature of a...

Stylish design, Bright and vivid OLED display, Excellent health tracking, Wear OS is a great match, Good haptic feedback

One-day battery life at best, Gimmicky capacitive rotating bezel, No Google Assistant support yet

The Samsung Galaxy Watch 4’s headline feature is a revamp of its software that combines the look and feel of Samsung’s existing Tizen platform and the functionality of Wear OS. It has good fitness features, strong battery life and a comfortable design. There are some compatibility issues, which may frustrate some potential buyers, but largely the Galaxy Watch 4 is an interesting iteration of Samsung’s top smartwatch formula.

Excellent performance; Interesting new software; Lightweight design;

Limited compatibility; Lacks rotating bezel; No exciting fitness upgrades

“The Galaxy Watch 4 has great health and fitness-tracking features in a comfortable build designed for smaller wrists.”

The high-end Galaxy Watch4 Classic features a stainless steel design and a rotating bezel backed by a better software experience and more third-party apps than previous Samsung smartwatches, though you can get a similar experience for $100 less with the standard Watch4 model.

Attractive classic watch design, Rotating physical bezel for easy navigation, Bright, sharp display, Fast processor, Body fat and composition measurements, Tracks snoring, More third-party apps than previous Samsung watches

Short battery life, Third-party app selection still trails Apple's watchOS

The Samsung Galaxy Watch 4’s sharp design, smart software and standout health sensor make for a promising upgrade that somehow costs less than last year’s version. Plus the Classic model still offers everyone’s favorite rotating bezel.

Slimmer design and new watch faces, New Wear OS feels like Tizen, but with more apps, First major smartwatch with body composition analysis, More affordable than Galaxy Watch 3

Concerns with BIA sensor, Battery life can be inconsistent

Even if you aren't a huge Samsung fan, you'll find a lot to like....

I'd love to say the new Samsung Galaxy Watch 4, which starts at $250 (£249), delivers the ultimate Android watch experience. I can't quite say that, but it's close. After wearing Samsung's newest watches for two weeks, however, I've liked it more over time. It's the first to run a whole new Google Wear OS co-designed by Samsung and Google, and while I'd say the future looks promising, the present looks a little unresolved. In a sense, my final feelings now are still pretty similar to my first few days wearing them.

This might be the best Android watch right now, but it's still missing a few pieces.

Lots of health-tracking features; Excellent display, fast processor; New Google OS includes Play apps; Great watch faces so far;

ECG and blood pressure features require a Samsung phone to use; Samsung Health still the default health app; Has Bixby instead of Google Assistant; Only 1-2 days of battery life;
