Smartphones are essential, but unsafe charging can pose serious fire and health risks. Firefighters warn that many incidents stem from common but hazardous habits.

**1. Under Pillows or Blankets**
Charging under soft covers traps heat, risking overheating and fires—especially overnight. Always charge in open, ventilated areas.

**2. Near Water**
Bathrooms, sinks, and tubs are risky spots. Water and electricity can cause short circuits or electrocution. Keep chargers far from moisture.

**3. On Beds or Sofas**
Soft surfaces trap heat. A malfunctioning charger or overheating phone can quickly ignite flammable materials. Use hard, non-flammable surfaces.

**4. In Direct Sunlight**
Sunlight increases heat, damaging the battery and raising fire risk. Charge in cool, shaded areas instead.
