On Windows you need to install the drivers for USB charging to work.
There are a few possible reasons for this. One possibility is that the USB port you were using did not provide enough power to charge your phone. Another possibility is that the USB cable you were using was damaged or of poor quality, resulting in a slow or interrupted charge. Additionally, certain apps or features on your phone may drain the battery faster than it can charge, leading to a net decrease in battery life.
Charging your phone through USB is generally safe for the battery. However, it may be slower than using a wall charger and could potentially cause stress on the battery if the USB port does not provide enough power. It is important to use a high-quality cable and ensure that the USB port you are using can adequately charge your phone.
Charging your phone through USB should not damage your device as long as you are using a quality cable and an appropriate power source. However, if the USB port or cable is damaged, it could potentially cause harm to your device. It is important to regularly check your charging equipment for any signs of wear and tear.
The time it takes to charge a phone through USB can vary depending on the device and the power source. Generally, it will take longer to charge a phone through USB compared to using a wall charger. It is also important to note that charging times may be affected by the phone's battery level, usage during charging, and the quality of the charging equipment.
Not all USB cables are created equal. It is important to use a high-quality cable that is specifically designed for charging devices. Using a low-quality or damaged cable can result in slow or interrupted charging, and could potentially damage your device. It is always best to use the cable that came with your phone or purchase a reputable replacement.
