Overnight phone charging may harm sleep and battery life

Over half of people charge their phones overnight, often keeping them within arm's reach while sleeping. This common habit, especially in big Russian cities like Moscow and St. Petersburg, may be harming both sleep quality and device safety. Experts warn that simple changes could make a big difference. Many leave their phones charging on beds, pillows, or soft blankets. This can cause batteries to overheat, shortening their lifespan over time. In rare cases, faulty cables or excessive heat might even spark a fire, risking damage to fabrics and bedding.

The glow from screens or standby lights can also interfere with sleep. Even a small amount of light disrupts the body's natural rest cycle, leading to lighter, more restless nights. Placing the phone on a nightstand and using Do Not Disturb mode helps reduce interruptions and encourages deeper sleep.

Experts suggest charging devices in the evening before bed instead of overnight. Wireless chargers are recommended to minimise heat buildup. Manufacturers also advise keeping gadgets in well-ventilated areas to prevent overheating and extend battery life. Small adjustments, like moving phones away from the bed and charging them earlier, could improve both sleep and device safety. Avoiding overnight charging on soft surfaces reduces fire risks and helps batteries last longer. These changes may lead to better rest and fewer distractions during the night.
