You may have heard that leaving a phone charger plugged into an outlet without a phone connected is extremely dangerous. The reality is more nuanced. A modern, good-quality charger generally uses very little electricity when idle, but unplugging it can still be a sensible safety habit.
Here are three reasons worth knowing.

Simple habit: Unplug chargers you’re not using, particularly if they’re easy to access.

The bigger concern isn’t normally the fact that a charger is empty. Damaged, counterfeit, poorly manufactured, or overheating chargers can present electrical and fire hazards.

-
Unusual buzzing

If you notice any of these signs, stop using the charger and replace it with a reputable, compatible one.
