1. Under Your Pillow or Blanket
One of the most common yet hazardous practices is charging your phone under a pillow or blanket. Heat generated by the phone has no escape route, leading to overheating and potential fires. This risk amplifies during overnight charging, as users are unaware of the increasing temperature. Firefighters stress that keeping devices in ventilated spaces can prevent such incidents.
2. Near Water (Bathroom, Kitchen Sink, Bathtub)
Water and electricity make a dangerous duo – one of the worst places to keep your phone. Charging your phone near water sources like sinks, bathtubs, or kitchen counters can lead to short circuits or electrocution. Firefighters emphasize the importance of keeping electrical devices far from water to avoid these preventable risks.
3. On Your Bed or Sofa
Soft surfaces like beds and sofas act as insulators, trapping heat emitted by phones during charging. If a charger malfunctions or the phone overheats, these fabrics can ignite quickly. Fire safety experts advise against charging phones on such surfaces and recommend using hard, non-flammable areas instead.
4. In Direct Sunlight
Leaving your phone on a sunny windowsill or near a heat source while charging is another common mistake. Direct sunlight accelerates overheating, compromising battery health and increasing fire hazards. Always keep your phone in shaded, ventilated areas during charging.
5. Inside a Car on a Hot Day
Cars can become ovens under direct sunlight, especially during summer. When a phone charges inside a parked car, the confined space and high temperatures intensify heat buildup, risking battery damage or explosions. Experts recommend removing phones from vehicles or charging them in cooler environments.
6. In Your Pocket
Storing your phone in your pocket may seem convenient, but it comes with hidden risks. According to Dr. Lilly Friedman, radiation levels are two to seven times higher when phones are kept in pockets, increasing the risk of tumor growth making it one of the worst places to keep your phone. Prolonged exposure may also affect male fertility and alter DNA structure. For safety, opt for carrying phones in a purse or holster.
7. Using Cheap or Damaged Chargers
Counterfeit or frayed chargers pose significant dangers, including sparks, short circuits, and battery explosions. Firefighters advise using certified charging accessories to minimize these risks. Regularly inspecting chargers for wear and tear is equally important to ensure safe operation.
8. Plugged in After Full Charge
Leaving a phone plugged in after it reaches 100% may not cause an overload, but it does result in heat buildup, particularly when using low-quality cables or stacking items on the device. Over time, this can degrade the battery. Unplugging once the charge is complete is a simple way to protect your phone’s lifespan.
9. In Your Bra
Some studies suggest a potential link between storing phones in bras and breast cancer due to radiation exposure. Though evidence remains inconclusive, the risk of skin irritation from bacteria on the phone persists. Experts recommend avoiding this storage method, especially during exercise, as sweat exacerbates the issue, making it the worst place to keep your phone.
