Firefighters and safety experts are warning people not to charge their phones on soft surfaces like beds, couches, pillows, or under blankets. These areas trap heat and can increase the risk of overheating, battery damage, or even fire.
Modern smartphones use lithium-ion batteries, which naturally generate heat while charging. When airflow is blocked by fabric or bedding, that heat can build up quickly. Several fire departments have reported house fires linked to phones charging on beds overnight.
One of the biggest concerns is charging your phone while sleeping with it under a pillow or blanket. Firefighters say this is especially dangerous because the heat cannot escape, and flammable materials nearby can ignite if the battery fails.
Safety experts recommend:
Charging phones on a hard, flat surface like a desk or table
Using original or certified chargers
Avoiding damaged cables or cheap knockoff accessories
Keeping phones away from water and direct sunlight
Unplugging devices if they become unusually hot
Some fire departments also advise against leaving devices charging unattended overnight, especially older phones or batteries showing signs of swelling or overheating.
A simple change in where you charge your phone could help prevent serious accidents and extend your battery’s lifespan.
