What is wireless charging?
Wireless charging, also known as inductive charging, is a method of powering devices without the need for physical cables. This technology uses electromagnetic fields to transfer energy between a charging base and the device. The most common application of wireless charging is for smartphones and other portable gadgets, allowing them to recharge simply by being placed on a charging pad.
Wireless charging operates using a transmitter coil in the charging pad and a receiver coil in the device. When aligned correctly, the coils create an electromagnetic field that transfers energy to charge the battery. This method not only simplifies the charging process but also reduces wear and tear on charging ports, thereby extending the overall lifespan of the devices.
Which phone was the first to use wireless charging?
The first phone to incorporate wireless charging technology was the Nokia 920, released in late 2012.
