Apple has issued an urgent warning urging users to avoid charging iPhones under pillows or blankets, citing fire hazards linked to overheating. This alert comes as the UK faces a heatwave, with temperatures hitting 33°C (91°F), exacerbating risks of device malfunction.

Why It’s Dangerous

Charging phones under pillows or bedding traps heat, increasing the likelihood of overheating. Lithium-ion batteries, used in iPhones, can ignite if exposed to high temperatures or physical damage. Apple’s guidelines stress keeping devices in “well-ventilated areas” while charging and avoiding skin contact with chargers.

Real-Life Incidents Highlight Risks

Firechief Global, a UK safety firm, echoed Apple’s concerns, noting that overcharging or using non-certified chargers heightens dangers. Laurie Pollard, managing director, advised charging phones on flat, non-flammable surfaces and unplugging them once fully charged.

One family in Glasgow lost their home after a bedside charger sparked a fire. Similarly, a Massachusetts teen suffered burns when her iPhone exploded while connected to a portable charger purchased online.

Faulty chargers or overheating devices can cause devastating fires.

Sleep Disruption Concerns

Beyond fire risks, sleep experts warn that nighttime phone use harms sleep quality. Screen light disrupts melatonin production, while notifications can cause anxiety. Dr. Ana Brito of the London School of Childcare Studies recommends a tech-free hour before bed to improve rest.

Safe Charging Tips

Avoid Overcharging: Unplug devices once fully charged.
Use Certified Chargers: Non-approved accessories may lack safety features.
Keep Devices Cool: Charge in open areas away from flammable materials.
Clean Charging Ports: Dust buildup can cause overheating.

Battery Care Tips

Experts advise keeping battery levels between 20–80% to prolong lifespan. Letting phones die repeatedly or leaving them plugged in overnight accelerates battery degradation.
