Overnight Charging
Many people charge their devices overnight. It makes sense; you’re asleep, so you can’t use the gadget, unlike when you need them while you’re awake. However, if you are a person who takes advantage of your sleeping hours to charge, you might want to power down completely.

There is a slight but realistic chance that your device could overheat while it’s charging. For example, if you’re asleep and your device catches fire, you may have a massive problem on your hands. However, if you power down your device, it won’t be able to heat up to problematic levels when you aren’t watching.
