Apple CarPlay and Android Auto Make Your Phone Hot. Here’s How to Keep It Cool

Apple CarPlay and Android Auto can make phones heat up and lose battery faster because the handset runs apps such as live maps while powering the car’s display. The article says drivers can reduce the strain by adjusting how the phone connects, where it sits and how much it has to do.

A wired connection usually puts less strain on the phone than a wireless one, though charging during the trip can add heat. Drivers can use charge limits, keep the phone out of sunlight, place it near an air vent or remove its case; downloading maps and media in advance also cuts workload. Airplane mode reduces activity further, but prevents calls and requires content to be stored on the device.
