Our smartphones are powerful, but very sensitive to heat. In summer, it’s common to see devices slow down, switch off or show overheating warnings. Here’s how to protect your phone effectively when the temperature rises.
Avoid prolonged exposure to the sun
Never leave your smartphone in direct sunlight. On a table, a garden chair or in the car, the temperature can climb quickly and put the internal components at risk.
Use a vent-mounted holder in the car, especially if you’re using GPS. And on holiday, always keep your smartphone in the shade.
Keep an eye on your battery temperature
An overheated battery will wear out more quickly. Type ##4636## to access the technical battery information. A normal temperature is between 25 and 35°C. If it goes above this range, switch the phone off immediately.
The charger you use plays a key role. An unsuitable model can cause overheating. Always choose original accessories.
Manage your smartphone’s activity
Apps running in the background and games put a heavy load on the processor. In hot weather, limit how much you use them and close them completely after use.
Turn off features you don’t need (Bluetooth, NFC, GPS) to avoid background activity that generates heat.
Encourage better ventilation
A full-cover case can prevent heat from escaping. To let your smartphone breathe, take the case off when it’s working hard.
Little bonus tip: if your smartphone is waterproof, a quick rinse under cool water can help bring its temperature down (as long as it’s rated IP67/68, of course).
