  • 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

    AMOLED

    Advanced OLED screen type with better visual experience, almost perfect black performance, thin and light but with higher energy consumption than Super AMOLED.

  • 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.

    Wonderful watch that has everything and lacks nothing! Battery lasts 2 days with everything on, if it had double the autonomy then it would be the top of its category

    Battery that definitely lasts 4 days (smart mode), NFC that works perfectly, excellent screen. I wasn't crazy about the strap but you can put any 18mm strap you want so no problem. Sports/measurements work and it has many modes but I can't judge if they are accurate. For someone who wants something compact (in size and price), with WearOS and NFC that doesn't need charging every day, I think it's the best choice.

    This review is about the colour: Black

    Very satisfactory battery, very fast charging and beautiful. A nice detail on the strap is that the second plastic clasp, which holds the excess strap, has a pin that goes into a hole in the strap. It doesn't move at all and there is no strap sticking out to get caught here and there and annoy you.
    Also, it has a very convenient function for stopping exercise: you have to press and hold the X, so you don't worry that it might accidentally touch something and stop your workout. The only thing I don't like is that it detects inactivity a bit faster than I'd like; in pilates, where your hands might not move for a few seconds, it pauses the session. A detail that I imagine won't bother those who don't do pilates

    Satisfied with my purchase, the battery life is about 2-2.5 days without AOD and with measurements turned on. Comfortable on the wrist and during sleep. It is for those who want a satisfactory fitness-wellbeing watch but also with the capabilities of a smartwatch that is fast and has access to the playstore. The measurements are very good for me, as I am not a pro. The call quality/sound (only call answering) is very good. NFC with Piraeus and National Bank is super. I haven't put it in water, I've been a bit scared by the reviews of other watches.
