Smartphones are essential, but improper storage and charging can pose serious risks. Firefighters and experts warn against charging phones under pillows, on beds, or in direct sunlight, as these conditions trap heat and can cause fires. Water sources like sinks and bathtubs also pose electrocution risks when phones are nearby or charging.

Storing phones in cars on hot days or in glove compartments exposes them to extreme temperatures, which can damage batteries. Keeping phones in pockets or bras may increase radiation exposure and health concerns, including fertility risks or potential links to cancer.

Using cheap or damaged chargers can lead to sparks or battery explosions. Experts recommend unplugging your phone after it’s fully charged and using certified charging accessories.

To stay safe, charge phones on hard, ventilated surfaces, avoid overnight charging, and keep them out of direct heat and moisture. A few simple precautions can protect your device—and your health.
