    Charge Galaxy Watches Using Flat Magnetic Charging Dock

    The following Samsung Galaxy Watch series use the magnetic flat charging dock:

    • Galaxy Watch Active
    • Galaxy Watch Active2
    • Galaxy Watch3
    • Galaxy Watch4 series
    • Galaxy Watch5 series
    • Galaxy Watch6 series

    These watch series include a magnetic charging cable in their packaging. If your watch’s original charger is missing or damaged, buy a replacement from Amazon or Samsung’s online store. Follow these steps to charge the above Galaxy Watch series with a magnetic charging dock.

    1. Insert the USB end of the charging cable into a wall charger or adapter.
    2. Next, plug the adapter into a power source—wall socket, power bank, power station, computer USB port, etc.
    3. Place your Galaxy Watch (facing upward) on the magnetic charging dock and turn on the wall outlet/socket.

    Samsung recommends using only authentic accessories to charge your Galaxy Watch. You’ll find Samsung-approved wall chargers on Samsung’s website or nearby Samsung Experience Stores.

    If you have the Galaxy Watch4 or older, ensure your wall charger has a 4.5W power output rating or higher. For Galaxy Watch5 and Watch 5 Pro, a 9W (or higher) adapter guarantees fast-charging speed. Chargers with power ratings below the minimum requirements will charge your Galaxy Watch slowly.

    The Samsung Galaxy Watch5 and Watch5 Pro have an updated USB-C charger that supports the Power Delivery (PD) fast-charging standard. Using the cable with a USB-C PD adapter will charge the Galaxy Watch5 faster than regular non-PD adapters.

These watch series ship with a wireless charging dock in their packaging. Buy a replacement charging dock from Amazon or Samsung online store if yours is faulty or missing.

    1. Insert a cable into the micro-USB charger port on the back of the charging dock.

    The embedded magnet in the dedicated spot holds your watch in place when charging. The third LED indicator should display a solid RED light when your watch charges and green when fully charged.

    Although Galaxy watches don’t support the Qi wireless charging standard, some third-party Qi-certified wireless chargers claim to charge Galaxy watches. Using these non-compatible charging accessories could damage your watch or its battery.

    Charging Tips for Samsung Galaxy Watches

    Samsung advises charging new Galaxy watches before using them for the first time after unboxing. You should also fully charge the smartwatch if left unused for lengthy periods.

    Charging speed will vary depending on your Galaxy Watch series, charger power rating, and other factors. For instance, the Galaxy Watch5 will typically charge faster than the Watch5 Pro because the latter has a bigger battery. According to Samsung, a 30-minute charge will fill the Watch5 by 45% and Watch5 Pro by 35%.

    Also, your Galaxy Watch will charge faster on its original/official charger than Wireless PowerShare or wireless charging pads. Generally, power sources with low electric current (computer USB ports, for instance) will charge your watch slower.

    Damages caused by unsupported accessories or improper charging aren’t covered by warranty. Hence, use only authentic or official Samsung charging accessories to charge your Galaxy Watch.

    Charging accessories don’t have the same water or dust resistance certifications as Galaxy watches. Avoid exposing your watch’s charger to liquid, sweat, or dust.

    Dry your Galaxy Watch with a clean cloth before charging it after any workout activity.

    Charging from a computer or using your Galaxy Watch while charging will increase the charge time. Charge your watch directly from a wall outlet and leave it to charge fully.

    An unstable power supply might cause your Galaxy Watch’s touch screen to malfunction while charging. If that happens, disconnect your watch from the charger, and try a different power source. Use a different power adapter or charging cable/dock if the touchscreen malfunction persists.
