What exactly is wireless phone charging, better known as “Wireless Charging” technology? Do you know how wireless charging works and which phones support it?
Charging your phone today is a matter of choice. There are many ways available to you and some of the most popular are:
- standard cable mode
- via external battery
- via another phone
- wireless charging
However, which of the following methods is the most convenient?
What is wireless phone charging
As you probably guessed from the name itself, wireless charging refers to the transfer of electricity from our everyday sources (city power grid) to the phone, without a cable connection.
In order for wireless charging to be possible, it is necessary that the phone contains a module that will enable it, or that the module be retrofitted with the help of a case.
Those phones that do not support both cable and wireless charging can be alternatively adapted for wireless charging, but this means a slightly more expensive cover with an integrated module in it, which makes the cover bigger and heavier.
How wireless charging works
Wireless charging is achieved by using the electromagnetic fields of one device (plate that emits electricity) to transmit electricity via a thin copper thread (module) to another device. This energy from the module is processed and later powers the battery. Since all the energy is first stored on a copper coil and then conducted to the battery, there is no risk of sparks, overheating, electric shock and the like, which guarantees safe use.
In translation, wireless charging requires two things:
1 – Plate that emits electricity. It can be a stand, a phone holder, a compartment of a purse, anything that the manufacturers remember. All that matters is that the board is connected to electricity.
2 – Module that receives electricity, ie a thin copper coil that communicates with the phone via a direct connection, whether via pins or microUSB.
When these conditions are created, simply charging the phone with the receiver (module) to the emitter (board) starts the charging process.
What is the purpose of wireless charging
Charging your phone without a cord is easy, convenient and fast. We all know that over time, cables get tangled up, which makes charging your phone a tedious job. This way, with wireless charging, just put the phone on the board and that’s it.
Let’s also mention that most airports and some of the slightly larger train stations in the world, have exposed panels through which passengers can top up their phone while waiting for their ride or flight.
But that’s not the end of the benefits of cordless charging because that standard is universal and virtually any device that supports wireless charging can be charged via the same board. So, it will reduce the piles of cables to charge all these devices, ie smart watches, tablets and phones. The list will only expand over time and imagine how convenient it will be when you power all your devices with just one cable and board. No clutter of adapters, connectors, tangled cables, broken cables and more.
What are the disadvantages of wireless charging
There are advantages and disadvantages to all devices and their mode of operation, including wireless charging. Charging without a cable may be slower than charging with a cable. Also, the amount of electricity consumed can sometimes be greater than that received by the phone.
Also, while charging the phone wirelessly, you are not able to recline in the armchair and use it, but it must stay on the board. It is true that you can use the phone while it is charging wirelessly, but only while it is on the board.
Which phones support wireless charging
Almost every newer phone model can be charged wirelessly, although in some cases, such as Apple phones, it is necessary to resort to alternatives such as cases that have an integrated wireless charging module.
On the other hand, manufacturers such as Asus, Google, BlackBerry, Cat, HTC, LG, Kyocera, Motorola, Nokia, Samsung, Sony, Vertu and Yotaphone often give this flagship to their flagship phones.
