Smartphone battery overheating caused by hidden location setting

Smartphones can overheat when the default location setting continuously scans for nearby Wi‑Fi and Bluetooth devices, even if the Wi‑Fi and Bluetooth icons appear off. The background scan can use up to 80% of processor and radio capacity, raising internal temperatures above 40 °C in direct sunlight and sometimes exceeding 50 °C. Prolonged exposure above 35 °C can degrade lithium‑ion batteries irreversibly, according to Google and Apple guidelines.

Manufacturers advise turning off the automatic Wi‑Fi/Bluetooth discovery feature—beyond merely disabling the visible icons—to reduce heat generation. Users should also move the device to shade, power it down, and allow it to cool gradually rather than using rapid cooling methods that may cause condensation and damage.
