I have a 2016 520d touring. I use the usb point to charge my iPhone 12. I use Spotify and maps, lately I noticed its doesn't seem to charge my phone, although I very rarely go on long journeys. I took my car to Liverpool a 3.5hr drive, using maps and music, by the time I had arrived, the phone was out of charge. It was plugged in the whole journey. It charged no problem in the hotel. I use an after market cable, someone told me it could be that. When its plugged in, the phone shows it is charging. Can you upgrade the usb point to a usb 2. Thanks

 I have never heard of this before, I think you need the OEM phone data cable to be sure. I have seen instances where after market cables don't allow all functions.

Also I take it that the USB port described is the accessory port ? Check your handbook is this actually a charging point or just a data transfer point ?

Thanks Dave, Ive ordered a genuine cable. The USB is a charging point. I'll let you know if the cable sorts the problem
