LTE Also known as cellular connectivity, this allows you to make and receive calls, texts and other notifications without your phone nearby. It's not available for everyone, as only a small number of network carriers offer LTE. Connectivity will also have a large impact on the battery life of the watch. And you'll need to consider the ongoing monthly cost.

The first digit after the IP reflects the level of protection against solids, such as dust or grit. The second represents the protection against moisture. An IP code with an X in place of either number means the device hasn't been tested for that element. Part of what helps to keep the battery going is the return of TicWatch’s secondary FSTN display which sits above the main panel and is able to convey key information like your step count, heart rate and the time of day in a low power state. Plus, it can now also flash a particular colour during a workout to indicate your heart rate zone without needing to wake up the watch. Battery life is compromised slightly to included it, but you’ll still get up to 20 hours of constantly using the impressively accurate GPS. That’ll be plenty for even marathons, with extensive running data combining with genuinely useful coaching for a great user experience. For its screen display technology, the smartwatch has a full circular screen display. A 1.28” inch TFT LCD screen, it’s a full touch screen with responsive and intuitive menus. With regards to its screen resolution, the wearable has a 240 x 240 pixel resolution, it’s inferior to other models, but still it gives crisp graphics, a bright color display. On top of the LCD is a 2.5D tempered glass protection with crystal clear clarity. SMT4 Smartwatch What We Think of the DesignIt also included weather forecast, alarm, remote camera support and preloaded with watch faces. Aside from preloaded watch faces, there is also additional watch faces available in the app. It has a metal body measuring 45.5 mm x 10.7 mm, a medium size wearable, that is light, and at the same time durable with its IP67 waterproof rating. It is splashproof, wash proof, and dustproof as well. Samsung Samsung watches run the Tizen operating system. Just as Apple Watches are best with an iPhone, you're better off with a Samsung-branded phone here. However, you will find good compatibility with other Android brands. Apps have historically been more limited on Tizen than on Wear OS, although this is slowly improving, with popular apps such as Spotify, Uber and Nest now available. There's some compatibility with iPhones, but some more recent releases, are not compatible. Overall it doesn’t boast the amount of upgrades that Garmin Fenix fans were probably hoping for, but that doesn’t mean that the Fenix 7 Pro isn’t still a great watch for fitness enthusiasts, and unless you want a few more smartwatch features from the more expensive Garmin Epix Pro (Gen 2), then you’ll get on well with what’s on offer here. However, three of these – ECGs, blood pressure monitoring and irregular heart rate detection – are only available if you have a Samsung phone. And even if you turn off the always-on display, a full day of battery life is only just within reach.

Sensors: acceleration sensor (SC7A20), heart rate monitor, blood pressure monitor, blood oxygen monitorUnlike the Galaxy Watch 6 Classic, the regular Watch 6 is a small upgrade compared to its predecessor – the Watch 5. This more affordable option ditches the Classic’s physical rotating bezel for an underwhelming virtual version, but it’s still excellent in many areas.

Other smartwatch brands that did not provide us with information on minimum update support periods include: Amazfit, Huawei, Mobvoi, Realme and Xiaomi. Samsung promises at least five years from launch on the Galaxy Watch4 and later, and three years on previous models. The only real downsides are that its app offering is behind Apple and Google’s and Fitbit, unlike Garmin, asks you to pay a subscription to access all the post-workout analytics the Versa 3 offers, which feels a bit cheeky. In addition to the improved mapping, Garmin has added a new heart rate sensor which, in theory, should produce more accurate results than before. In testing however, we struggled to see any noticeable difference with the newer sensor, so if you want the most accurate data possible then we still recommend grabbing a chest-worn heart rate strap. Galaxy Watch 6 smartwatches run Wear OS 4 with Samsung's One UI 5 Watch software. They require a smartphone running Android 10 or higher with more than 1.5GB of RAM. Note that although you can pair the Watch 6 with non-Samsung Android phones, some features work only with Samsung handsets, including irregular heart rhythm notifications, phone separation alerts, and the Camera Controller app.However, now with the fifth version available Apple Watch is a significantly matured product compared with the initial release, both in hardware terms and the suit of fitness and health-related applications available.
