  • 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.
