It works by transferring energy between a transmitter and a receiver through an electromagnetic field. But does this convenient technology come at the cost of battery life? To answer this question, let’s dive into the science behind wireless charging and its potential impact on battery life.
The Charging Process: How Wireless Charging Affects Battery Health
When a device is charged wirelessly, the transmitter coil in the charging base generates an alternating magnetic field. This field induces an electromotive force (EMF) in the receiver coil within the device, which is then converted into electrical energy to charge the battery. This process is known as electromagnetic induction.
The charging process itself does not directly affect battery life. However, the heat generated during wireless charging can have an impact on battery health. When a battery is charged, it naturally heats up due to the internal resistance of the battery cells.
