In fact, many people like to charge their mobile phones while driving, and then turn on the navigation. However, it didn't take long to find that the mobile phone battery is becoming less and less durable, which is likely to hurt the mobile phone battery. Because if you charge the car USB interface directly, it will happen. The USB interface set in the car is only prepared for ordinary audio transmission data. The voltage of this interface is only 5V/0.5A If the mobile phone is charged at this substandard current and voltage for a long time, it will damage the battery of the mobile phone.
The more the mobile phone is charged, the more difficult it is to charge the audio transmission interface of the car USB, and use it while charging. Although the phone will show that it is charging after being connected, the current is very small. If you turn on the mobile phone to locate and navigate at this time, the charging speed will definitely not keep up with the consumption speed, so this will happen.
