Samsung Galaxy Watch4 40mm

The first watch with Wear OS

The flagship watch of the South Korean company Samsung in 2021, as befits a premium device, offers everything you need for convenient use, and even more. These are high-quality materials, and a set of various sensors for monitoring the state of health, and almost unlimited possibilities. But, perhaps, the feature of the fourth generation is precisely the “hardware”: this is the first Samsung watch in many years without the Tizen operating system. Instead, Wear OS is used, and a completely new version, for which Samsung and Google have joined forces to create. And this is good news for those users who scolded Tizen OS and remembered the good old Wear OS with nostalgia. And if you add to this the new Exynos W920 processor and increased memory (1.5 GB of RAM and 16 GB of ROM), you get fast work, smooth interface, instant application launch and close interaction with other gadgets of the ecosystem like wireless headphones, TV, etc. d. For example, right from your wrist, you can enable noise cancellation on your headphones or open an app on your smartphone. The only caveat is that the watch is not compatible with the iPhone, although lovers of "apple" gadgets are unlikely to need it.

In addition to displaying incoming calls and notifications, the device allows you to answer calls, make payments with Samsung Pay, give commands to the Bixby voice assistant and download your favorite playlist while listening to music without a smartphone.

Personal physician and trainer

Another innovation was the Samsung BioActive sensor, which can measure ECG and blood pressure in real time. However for a full analysis, you need the Samsung Health Monitor application, and it is available only on Samsung Galaxy phones. In addition, the watch measures heart rate and blood oxygen levels, counts the number of steps taken and calories burned, monitors sleep, determines the nature of snoring, and even knows how to analyze body composition by determining the amount of fat, skeletal muscle and water in the body.

The big problem for owners of wearable devices is battery life, and you need to understand that the more functions, the less time a smartwatch will work on a single charge. The Samsung Galaxy Watch4 has a 247 mAh battery, which will last a maximum of several days. If you actively train and turn on automatic SpO2 measurement and the Always On screen, you will have to charge the gadget daily.

Design

By the way, the range also includes a 44mm version and a Galaxy Watch4 Classic model with a branded rotating bezel. But we would recommend the 40-mm Galaxy Watch4 to the female half — smaller and more accurate, with a durable aluminium case, a small Super AMOLED display with a diagonal of 1.2" and weighing only 26 g. At the same time, the younger version retained compliance with the MIL-STD-810 protection standard and water protection IP68.
