Using CarPlay or Android Auto can make phones run hot, and the source explains that this is due to a combination of environmental heat, wireless charging, and heavy multitasking. Navigation apps constantly process data and render 3D maps, while wireless projection uses Bluetooth, Wi-Fi, and cellular radios at once.
The article notes that wireless charging generates more waste heat than USB, and leaving a phone in direct sun or near a hot vent can push temperatures higher. When a phone overheats, it may throttle performance, stop charging, or shut down to protect itself.
Practical fixes include avoiding charging on short trips unless needed, using USB instead of wireless when possible, and positioning the phone away from sun or heat sources. The source also suggests using 2D maps, limiting audio apps, and rebooting the phone periodically to clear caches.
