Back to the Watch 4: On paper, the overall upgrade over its predecessor is also limited in terms of software and hardware, but as this review of the Samsung Galaxy Watch 4 shows, it’s great for anyone looking for a high-quality smartwatch that can record workout data and offer many other smart features that many other wrist companions don’t. However, the Galaxy Watch 4’s compatibility is inexplicably worse than previous Samsung watches. If you own an iPhone, it won’t work with it, and while it’s compatible with all modern Android phones, you’ll need to own a Samsung smartphone to access some features like blood pressure or ECG readings. This is disappointing, of course, because Samsung’s smartwatches so far are among the best in terms of compatibility. We think the Watch 4 is worth buying even if you own a non-Samsung Android smartphone, but you should note that there are some limitations. The fitness features aren’t much different from what we’ve seen before, but there is a new body composition tool that gives you a rough idea of your body fat percentage. We found that GPS, heart rate monitoring, and other fitness features are well thought out on the Galaxy Watch 4. Battery life isn’t a big issue with the Galaxy Watch 4, but it’s not the most enduring smartwatch we’ve seen. It lasts about two days with normal to heavy use, and about three days if you’re not exercising or using features like GPS. The Samsung Galaxy Watch 4 is a slim smartwatch with a design that sits comfortably on the wrist. If you’re looking for a chunkier watch or want a rotating bezel, you should opt for the Samsung Galaxy Watch 4 Classic. For those looking for a slimmer design, the Galaxy Watch 4 fits the bill, with two buttons on the right edge and little to distract from its sleek appearance. There are two models, one with a 40mm dial and one with a 44mm case. Both models are made of aluminum. The dimensions of the 40-mm model are 40.4 x 39.3 x 9.8 mm with a weight of 25.9 g, while the 44-mm model measures 44.4 x 43.3 x 9.8 mm and weighs 30.3 g. We wore both models and found both to fit comfortably without weighing down our wrist. We used the 44mm model for a longer period of time than the smaller model and found it to be the right size. It is comfortable to wear throughout the day, although it may not be the best choice for nighttime sleep monitoring.
