  • Battery Life

    Battery life shows how many days the smartwatch can operate without charging.


    It depends on the battery capacity, but also on how much you use it (e.g. active display, GPS, notifications, etc.).


    For example, a smartwatch with 2-3 days of battery life is ideal for daily use with all features enabled.


    Models with 5–10 days or more are suitable for those who do not want to charge often or use it more "lightly".


    The value is especially meaningful when comparing products from the same manufacturer.

  • Display Type

    OLED

    They perform better in darker spaces, with almost perfect black rendering, natural images and high color accuracy. They have lower power consumption compared to LCD/IPS.

  • Waterproof

    Pool Swimming

    Equipped with a high level of waterproofing, the smartwatch can be comfortably used during pool swimming. Track your performance in the water without worrying about the safety of the device.

    I can say with certainty that the watch is very good. By setting the screen not to be always on, the battery lasts much longer. I clarify this because I read that it doesn't last a day, but that's not true. With proper settings, it lasts a whole day+. Personally, the battery is just fine for me, as I usually put it on charge after activity, take a shower, and I don't even notice when the notification comes that the watch is charged. Ideal size (44mm) and weight. Clearly, we wouldn't mind having an ultra, but it really is totally worth its money.

    Gift for the girl, the only thing that annoys her is the battery that you have to chase every day to charge the phone or the watch? Other than that, very powerful and useful.

    iPhone user for 10 years and HUAWEI GT 5 Pro smartwatch, I just saw and experienced the -non-compatibility with the iPhone and so it was finally time for an Apple Watch. The watch is ok, however in my opinion it does not compare to the respective HUAWEI ones. The only thing that disappointed me quite a bit is the very low brightness as well as the screen itself, in terms of clarity. I would have expected something better.

    The most budget-friendly Apple Watch at the moment. For the average user, you don't need anything more than what it already offers: NFC, WiFi, Activities, App Store to download apps, personally I don't miss anything. Only one complaint... the darn thing. It exists and consumes battery just by being there, the insatiable one. Come on, there should be a limit!
    If you are one of those people who will say "I'll charge the watch along with my phone" and you don't want to spend €150+ for a higher category Apple Watch just to gain a few extra hours and some extra features, you'll be just fine.
