  • 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

    Water Contact

    The smartwatch is designed to withstand simple contact with water, such as rain droplets or sweat. It is the ideal choice for daily use, offering safety and functionality even in wet conditions.

Battery Capacity

Most smartwatches have a battery capacity of around 200mAh. 2. The size of the battery is not always indicative of the autonomy, as this largely depends on the features of the smartwatch and the functions we have active. 3. For example, a smartwatch with a large color touch screen and 24-hour heart rate monitoring will often require charging even if it has a larger battery than a simpler smartwatch.

    This review is about the colour: Black

    The watch is excellent in terms of quality and functionality, I don't know why someone writes about the time being wrong, probably their app is sending wrong data to the watch. So, no problem for me, everything is perfect, never wrong anywhere. Sturdy metal construction, beautiful and very good strap. I am extremely satisfied.

    This review is about the colour: Black

    The job of every watch is to show the time; this one, if it is not permanently connected to the phone, shows whatever. All the other functions are good, but if it doesn't show the time correctly, the main use is lost.
