Wireless charging is the Trend these days and Apple had introduced wireless charging in IPhone 8, IPhone 8 Plus and IPhone X. But, “Wireless” charging is literally not wireless as one have to connect the charging pad to the power source by means of a wire and keep the mobile on charging pad.

HOW IT WORKS :

In Layman words, Wireless charging is nothing but the conversion of magnetic energy into electrical energy using the concept of Induction. When the charging pad is powered, a magnetic field will be created around it. The coil present in the Mobile Phone places on the charging pad will convert this magnetic energy into electric energy and thereby charging the mobile.This process is called Magnetic Induction and most of the Smartphones that support wireless charging will use this method.

There is another method called “Magnetic Resonance” by which the process of wireless charging can be achieved. In Magnetic Resonance, there is no need for the device to be attached to the charging pad, but it can be present at a distance almost about 50 mm.

Is Wireless Charging Better than Wired ?

If wireless charging is so simple and easy to implement, why can’t all Smartphone manufacturers implement wireless charging for their smartphones.

Wireless charging has its own set of cons along with its pros.

PROS OF WIRELESS CHARGING:

  1. NO need of using wires. So, no pain of untangling the messed up wires.
  2. Wireless charging looks lot more cleaner and good when compared to wires charging.
  3. Easy to put a device on charging mode. After a tiring day, it’s easy to just drop a device on charging pad rather than searching for wire and then charging the device.
  4. No need for charging port on the device. So, Device manufacturers can use that space for incorporating additional features.

CONS OF WIRELESS CHARGING :

  1. Hands down, Wireless charging is always slow when compared to wired charging.
  2. Devices might heat up as there will be loss of energy in wireless charging.
  3. Although it’s wireless, one has to carry the charging pad along with the connecting wire.
  4. Wireless chargers are so expensive when compared to wires chargers.

CONCLUSION :

Confused of whether wireless charging or wires charging is better ?

Here is a Simple Answer :

When you need quick charging, go for Wireless and if you have time to charge, go for Wireless charging.
