Phone Connection Keeps Dropping

A phone that keeps disconnecting from the car by Bluetooth or cable usually has a worn cable, a phone or car software issue, too many paired devices or interference.

Normal risk

Not urgent. Avoid handling the phone while driving while you fix it.

Short answer · Why does my phone keep disconnecting from the car?

Bluetooth links can drop when the car has too many saved devices, when phone or car software is out of date, or when battery-saving settings on the phone cut the connection. Wired phone mirroring is very sensitive to cable quality; a worn or cheap cable is a common cause. Dirty or worn USB ports also cause drops.
