Why you shouldn't charge your iPhone while you sleep, Apple warns of the dangers
Apple has issued a stark warning to smartphone addicts who fall asleep holding their device close while it's connected to a charger.
In its online user guide, the tech giant says iPhones should only be charged in a 'well-ventilated area', ie on a flat table and not next to the bed.
iPhones heat up while charging, so if that heat doesn't have a place to escape, it has the potential to cause burns or even fires.
That's why keeping a charging phone under your pillow is one of the worst things smartphone users can do.
