Millions of Britons are risking catastrophic house fires by committing a common bedtime mistake that fire safety experts are calling a ticking time bomb.
New research reveals that nearly two-thirds of smartphone users regularly charge their devices overnight in bed or under pillows, creating potentially deadly overheating conditions that could lead to devastating blazes.
The Hidden Dangers in Your Bedroom
When phones are charged on soft surfaces like beds, sofas, or under pillows, heat becomes trapped around the device. This prevents proper ventilation and can cause lithium-ion batteries to overheat to dangerous levels.
"People don't realise they're essentially creating a fire hazard right next to them while they sleep," explains electrical safety expert David Jones. "The combination of heat buildup, flammable materials, and electrical current is a recipe for disaster."
Critical Mistakes You're Probably Making
- Charging on soft surfaces - Beds and pillows trap heat around your device
- Using non-certified chargers - Cheap alternatives lack safety cut-offs
- Ignoring battery swelling - A bulging battery is a clear danger sign
- Covering devices while charging - Never place anything over charging phones
- Leaving devices charging unattended - Overnight charging is particularly risky
How to Charge Safely and Prevent Disaster
- Always charge on hard, non-flammable surfaces like nightstands or desks
- Use only manufacturer-approved chargers with proper safety certifications
- Avoid charging overnight while sleeping
- Keep charging areas clear of flammable materials like curtains or paperwork
- Regularly check cables for damage and replace immediately if frayed
- Never cover charging devices or place them under bedding
Fire services across the UK have reported numerous incidents where phones have overheated during charging, causing significant property damage and putting lives at risk. The London Fire Brigade has specifically warned about this growing danger in urban households.
Recognise the Warning Signs
Watch for these red flags that indicate your phone or charger may be dangerous:
- Device becomes unusually hot during charging
- Battery appears swollen or misshapen
- Charging cable feels hot to the touch
- Battery drains unusually quickly
- Device restarts randomly during use
If you notice any of these warning signs, stop using the device immediately and consult a professional. Your safety could depend on recognising these danger signals before it's too late.
