Two years ago, I remember my teacher gave me advice when I want to charge any device, I should plug the charger into the device before plugging the other end into the electrical outlet. Why?? Does it have to do with preserving the device or the battery? Additionally, when finished charging the device, it's important to first unplug the end connected to the device from the electrical outlet before disconnecting the charger from the device.
