The habit of keeping the power adapter plugged in after disconnecting your smartphone is not as safe and harmless as it seems. It wastes electricity, accelerates the wear and tear of the charger, and in some cases can lead to overheating or even fire.

Why is a loose charger in the socket a threat?

Even without a gadget connected, the charger continues to draw current through the built-in converter. Although the power consumption is minimal, this "silent consumption" can add up to several extra kilowatt-hours over the months. Constantly being connected to the mains also causes the components to heat up: capacitors gradually degrade, current flow deteriorates, and the adapter's life is noticeably reduced.

Branded chargers are usually designed to withstand overheating and voltage fluctuations, but cheap analogues do not have such resistance. In the worst-case scenario, an overheated unit can smoke, short out, or become a source of fire. Therefore, disconnecting the adapter from the mains is a simple step that will extend its service life, save energy, and reduce the risk of fire.

As a reminder, the prices of chargers vary significantly, sometimes even tenfold. It may seem that buying a more expensive one will cover all your needs, but this is not always the case.

We also wrote that the trend towards wireless technology has been around for a long time, and most of us rightly expect that soon all devices will also be completely cable-free. Despite this, wireless charging is not as convenient as it seems at first glance.
