Does the USB power off after locking the Audi A6L?

Audi A6L's USB ports power off after locking the vehicle. Advantages of USB devices: Hot-swappable capability allows users to connect external devices without shutting down or restarting the computer - they can be plugged in and used while the system is operational. Highly portable. Most USB devices excel in being "small, lightweight, and thin," making them extremely convenient for users who need to carry large amounts of data. Functions of USB ports: Playing music via USB flash drives. Charging mobile phones. Cigarette lighter adapters for vehicles. Car vacuum cleaners. Radar detectors and dash cams. Additionally, USB ports can enable dual-device interconnection through specialized USB cables and expand more ports via hubs.
I've been driving an Audi A6L for over two years, and indeed the USB ports cut power after locking the car, stopping phone charging halfway. Audi designed this to protect battery life, preventing prolonged discharge that could cause starting difficulties. For daily activities like USB charging or playing music via USB drives, the power automatically cuts off a few minutes after turning off and locking the car—pretty smart. I once waited in a parking lot and noticed the dashboard lost power, naturally the USB did too. If you temporarily need to charge, I suggest using a cigarette lighter to USB adapter; that might last longer. Overall, with proper car maintenance, these minor issues aren't bothersome.
