Ever grabbed your phone from under your pillow while it was charging and found it surprisingly hot? Maybe had your laptop charging on your lap and get a little too warm for comfort?
Charging devices generate heat, and a little warmth while charging can be normal. What we're talking about here is something different. If a device becomes unusually or excessively hot, particularly if that's a change from how it normally behaves, stop charging it and pay attention. Swelling, changing shape or colour, unusual smells, popping or hissing noises, or smoke are other warning signs that something isn't right.
And please, please, please don't charge your phone or other devices on soft surfaces, or buried under things that can trap heat or restrict airflow. Beds, couches, pillows and blankets can all contribute to heat buildup around a charging device.
Charge on a hard surface like a table, desk or floor, and somewhere you can be alerted if something goes wrong.
