Charging cables can be troublesome due to their length, and often they are not found when you need them most. For these and many other reasons, wireless charging of cell phones is extremely popular.

To the delight of many users, more and more smartphones can be charged wirelessly. But how does it work at all, and is there a way to retrofit cellphones that cannot be charged wirelessly? You can find out here.

What is wireless charging?

Wireless charging is a technology that can be used to charge battery-powered devices without a cable connection to the power grid. The best-known devices that can be charged wirelessly include smartphones.

But other electrical devices, such as electric toothbrushes, can also be charged wirelessly. To do this, place it on a compatible charging station . A direct connection of the toothbrush or smartphone to the socket is not necessary. However, the respective station must be connected to the energy source by cable. Often it doesn’t work without a cable.

However, wireless charging stations can be easily installed in everyday items such as cars or furniture. For example, IKEA already offers furniture that is equipped with a charging pad.

How does the wireless charging function work?

The wireless charging function is based on the induction principle . And this is how it works: Electric coils are installed under the hood of the smartphone and charging station. The current flows through this inside the device.

The electrical current is converted into a magnetic field in the charging station. If you place the smartphone on the station, this energy is absorbed, converted back into electrical energy in the coil inside the smartphone and the battery is charged .

Since more energy can be transferred via the direct connection from the charging cable to the socket, wireless charging usually takes a little longer than with a cable. However, the speed also depends on how many watts the cell phone can be charged wirelessly and how much the charging station allows.

However, technical developments ensure that wireless charging works faster and faster , and charging is faster compared to older models that can only be charged with a cable.

What is the Qi standard?

As part of the development of the wireless charging function, the Wireless Power Consortium – an amalgamation of various electronics manufacturers such as Nokia, Sony and Samsung, which are dedicated to the further development of wireless charging – already agreed in 2008 on Qi technology as the standard for wireless energy transmission.

However, other technologies that enable wireless charging, such as the Powermat or Renzence, only play a subordinate role and cannot keep up with the range of Qi.

The term “Qi” comes from Chinese and means something like “life energy”. Most mobile phones that can be charged wirelessly are now equipped with the Qi standard , which has had a major technical impact on this function.

These include the Samsung Galaxy S models, for example the Samsung Galaxy S20 , the Google Pixel 4, the Huawei Mate 30 Pro and P30 Pro, the Nokia 9 PureView, but also the iPhone 11 and iPhone 11 Pro (max ).

Can cell phones be retrofitted for wireless charging?

Owners of older smartphones are lagging behind when it comes to wireless charging. However, many cell phones that cannot be charged wirelessly can be easily and inexpensively retrofitted .

The easiest way to do this is with a cell phone case in which a Qi receiver is integrated, with a Qi sticker or with a Qi receiver that can be installed on the cell phone without a case.

To do this, you plug the plug into the charging socket on the mobile phone and fold the attached Qi mat onto the back of your smartphone. In the case of a cover, this is already integrated in it. Now you can put your cell phone on any station for charging.

Reverse charging: the next step in wireless charging

The next evolution in wireless charging is reverse charging technology. One of the first manufacturers to integrate reverse charging in their smartphones was Huawei with the P20. But Samsung has also discovered this technology for itself and equipped the Galaxy S20 and Samsung Galaxy Note 10 with it.
