If you sleep near your phone, you are playing with fire.
More than 60 percent of adults sleep with their phone within arm's reach, but it's a dangerous practice. Charging your phone or tablet near your bed is a fire hazard that most people don't know about, according to the National Sleep Foundation.
In particular, you don't want to fall asleep with your phone on your bed, or especially under your covers. A phone releases a lot of heat to keep the device cool. If it is under a blanket, for example, heat can build up and damage the phone or cause it to overheat. In extreme cases, it could burn you or catch fire.
Instead be sure the phone is charging on a flat, open surface with lots of ventilation.
Never use a frayed cable for charging. Just change it out. Cables are cheap, but fires are deadly.
The biggest safety risk is a damaged and swollen lithium-ion battery. You might notice some loose adhesive between the screen and the housing, according to Tom's Guide. Or you might see the screen pull away from the housing. That means your device battery is swollen. If this happens, do not charge it. Stop using it immediately. Place it on a flat, cool, fire-resistant surface and keep and eye on it, allowing the battery to run down. Contact the manufacturer or a repair shop.
