I'm thinking about buying a smartwatch and would like to know the best way to approach this. In general, what criteria should we prioritize? For example, the quality and readability of the screen, battery life, the types of health sensors included (heart rate, blood oxygen, etc.), compatibility with the mobile operating system, and the ease of use of the interface. It's also important to consider the price range and whether the device allows customizing watch faces or adding apps. What do you all think? What aspects do you consider essential before making a decision?

Two years ago, I decided to swap my old traditional watch for a smartwatch because I needed something that could keep up with my workouts while seamlessly integrating with my Android phone. My first test was comparing screen readability under different lighting conditions. I tried several models with OLED and AMOLED displays; the one I chose, a Galaxy Watch 4, offered vibrant colors and enough brightness to read outdoors without straining my eyes—something I had ruled out in cheaper LCD models. Plus, the 450 × 450 px resolution made heart rate and blood oxygen metrics clear and easy to interpret.
Battery life was another critical factor. I needed at least a full day of heavy use (running, sleep tracking, and notifications) without charging. After testing a model with a 300 mAh battery that barely lasted 12 hours, I upgraded to one with a 340 mAh battery and more efficient power management. With moderate use, it lasted 1.5 days, and even with intense training, it made it to 24 hours without issues. That difference meant fewer interruptions and more confidence in the recorded data.
Finally, compatibility and customization sealed the deal. The watch I chose syncs perfectly with the Samsung Wearable app, offers customizable watch faces, and an app store with everything from route maps to productivity tools. It cost around €250, but when I compared it to other high-end options, I found it included more sensors (ECG, SpO₂) and a smoother interface than cheaper models. In short, prioritize a readable screen, a battery that fits your routine, and the ability to customize both the watch face and apps—all while staying within your budget and matching your phone’s ecosystem.
