Why You Should Stop Charging Your Phone In Your Car

Charging your phone in your car may seem convenient, but it can have negative effects on your phone’s battery. Here are a few reasons why you should stop charging your phone in your car:

  1. Inefficient charging: USB ports in cars typically do not provide sufficient power to charge a phone quickly and efficiently. This means that it may take longer to charge your phone compared to using a wall charger.
