Summer alert for iPhone users: Don't leave phones charging overnight in air-conditioned rooms, warns Apple

Dubai: As summer temperatures grip countries across the Gulf and Europe, Apple has issued an urgent warning to iPhone users: avoid charging your phone under your pillow or blanket — it could lead to overheating, injury, or even fire.

The caution comes amid rising concerns over device safety in countries currently experiencing hot climates, where indoor and outdoor temperatures can already strain electronic devices. Apple’s latest statement specifically warns against prolonged heat exposure during charging, especially in poorly ventilated spaces such as beds or sofas.

"Don’t sleep on a device, power adapter, or wireless charger, or place them under a blanket, pillow, or your body when it’s connected to a power source," Apple stated. "Sleeping or sitting on the charging cable or connector should be avoided."

The tech giant added that while iPhones and official Apple chargers comply with global safety standards, continuous contact with warm surfaces — even within acceptable temperature limits — can still result in discomfort or burns.

Users are also advised to:

The warning is especially relevant for those who leave phones charging overnight in air-conditioned rooms, where airflow may be limited or phones are left beneath bedding.

Apple’s guidance comes during a time when smartphones are already under greater stress from extreme weather, increased screen time, and intensive app usage, particularly during summer holidays.

For now, the best practice? Charge your iPhone on a hard, flat surface — away from soft furnishings and direct sunlight.
