The amount of power supplied through a PC’s USB ports: USB 2.0: 5V, 0.5A; USB 3.0: 5V, 0.9A.
You can charge your device if it is connected to your PC with a cable. However, your device’s battery charging performance may vary, depending on how you’re using Samsung DeX. In general, a PC’s USB port supplies less power than a regular charger. Therefore, if you run apps that require high processing speeds that take up resources through Samsung DeX, the amount of power used by your device will be greater than the amount supplied through the USB port. In this case, the battery level may still drop gradually even if you are charging the device.
