Tips for charging your Samsung Galaxy watch
Samsung advises that you charge your new Galaxy watch before using it for the first time after unboxing. You should also fully charge your smartwatch if it is not used for a long time.Charging speed depends on the Galaxy Watch series, charger wattage rating, and other factors. For example, the Galaxy Watch5 typically charges faster than the Watch5 Pro because the latter has a larger battery. According to Samsung, a 30-minute charge will charge the Watch5 by 45% and the Watch5 Pro by 35%.Additionally, your Galaxy Watch will charge faster on the original/official charger than on Wireless PowerShare or wireless chargers. Typically, power sources with low electrical current (such as computer USB ports) charge your watch more slowly. 
The warranty does not cover damage caused by the use of unsupported accessories or improper charging. Therefore, use only original or official Samsung charging accessories to charge your Galaxy Watch.Charging accessories do not have the same water and dust resistance certifications as Galaxy watches. Do not expose your watch charger to liquid, sweat or dust.Dry your Galaxy Watch with a clean cloth before charging after a workout. 
Charging from a computer or using the Galaxy Watch while charging will increase charging time. Charge your watch directly from a wall outlet and allow it to fully charge.An unstable power supply may cause your Galaxy Watch’s touch screen to malfunction while charging. In this case, disconnect the watch from the charger and try a different power source. If the touch screen problem persists, try using a different power adapter or charging cable/dock.
