96 degrees — up from 81 in 30 minutes — was reached by a phone that was charging while streaming music, illustrating how summer driving can trigger overheating.
Dashboard use is a common risk because GPS, music, Bluetooth and charging stack heavy workloads while direct windshield sun raises temperatures further.
Cheap chargers and damaged cables can add excess heat, so the report advises using reputable accessories and skipping charging during navigation unless battery is low.
If a phone shows an overheating warning, move it out of sun, power it off, remove the case and let it cool naturally; refrigerating it can cause condensation and possible water damage.
Repeated overheating matters more than a single incident because heat steadily degrades batteries, potentially shortening a phone's useful life by another year or two.
