Should the car data cable be unplugged?

Leaving the car charger plugged into the cigarette lighter won't affect the battery. Firstly, the car charger uses a series-switching regulated power supply, which remains powered off when no charging device is connected. Additionally, its static current is only about 1-2mA, causing no impact whatsoever. Relevant information about car Bluetooth is as follows: 1. Function: After successful Bluetooth pairing, you can use your phone to play audio files, answer calls, making it very convenient to use. While driving, it ensures driving safety. Once the car's infotainment system is connected to the Bluetooth system, you can make calls directly through the infotainment system in hands-free mode. 2. Automatic connection: Once your phone is connected to the car's infotainment system, it will automatically reconnect upon subsequent use, provided the phone's Bluetooth system is turned on. There's no need for frequent reconnections, saving time and adding convenience to vehicle use. However, when using Bluetooth calls, be mindful of privacy concerns.
