Do you have to unplug the phone to fully charge it?

The most feared thing of modern people is definitely one of the things that the mobile phone is out of power. In fact, the simple thing of charging is also learned! For example, does the mobile phone have to be unplugged when it is fully charged?

The answer is no.

First of all, most of the mobile phones currently on the market have a power management system, which will automatically stop the input current after being fully charged and will not cause overcharge problems.

Secondly, today's chargers have a complete full automatic stop function, double protection partners do not need to worry too much, of course, it is also necessary to choose a correct data cable.

So, when charging the mobile phone, should I plug in the mobile phone or plug in the power first? After charging, should I unplug the phone first, or unplug the power? Once the order is wrong, it will easily shorten the life of the phone!

Before charging the mobile phone, plug in the power supply first and then the mobile phone. If the mobile phone is plugged in first, a relatively large voltage pulse will be generated at the moment of charging, which may cause harm to the mobile phone.

After the mobile phone is charged, unplug the phone first and then the power source. If the power source is first unplugged, it is easy to produce reverse transient current, which may also cause harm to the phone.
