Wireless Charging of mobile phones
For
the 4.77 billion mobile users in the world, all of them are unified by
one single question: how to keep the battery of their mobile charged all
the time. All of us who own smartphones have to charge it daily in
order to keep us connected with the universe.
Therefore,
as long as those mobile phones are not invented whose battery lasts for
days, we have to confront with this menace of charging every day for
the remainder of our lives.
While it doesn’t really differ from its traditional counterpart in terms of the battery timing, the wireless charging will surely save our homes from the invasion of charging cables.
Thus, whether we’re at an airport, traveling by train or eating at our favorite restaurants, wireless charging has the ability to revolutionize our lives.
According to experts, the wireless charging method isn’t as effective as its traditional counterpart. However, for a normal person like me who has grown tired of searching for adaptor cables, this is a very minute shortcoming.
Another shortcoming – which will be overcome in the future, is the lack of distance between the charging device and your mobile. As this technology is still in its embryonic phase, you have to put your mobile over the wireless charging hardware so that it catches the signals.
However, there is a common consensus amongst scientists that this loophole would be eradicated in the coming years. Thus, in the future, it is probable that wireless charging could go on even when the two devices – the mobile and the hardware charging device, are inches apart.
That is to say, that after using them for a limited time, we have to throw them into the dustbin. Eventually, they become a part of the ever increasing landfill of mobile batteries.
However, when it comes to the wireless batteries, they have a huge shelf life. As a result, it would be a rare sight when you would see a person disposing of the wireless battery of his mobile. Therefore, complying with the Paris Accord, we’ll be polluting our planet even less.
Another advantage of the wireless charging – though not as mainstream as mobile charging, is equally effective. At a time when companies like Tesla are developing Electric cars, there will be a problem in the future where we will be queuing up in front of the electric pumping stations.
However, if you could afford a wireless charging at that time, it will not only save you time but will also save you the resources.
As reported above, Qi is based on the principle of electromagnetic charging. It comprises of tightly coiled wires which produce and receive the EMF. The Power which is taken up by Qi is 5W – which is surprisingly similar to its standard counterpart.
While Qi boasts of an efficient power transfer, a new user could be easily entangled in this web of coils. For example, if you have disturbed the alignment of coils in the hardware charging unit and your mobile, it is likely that your mobile could misbehave.
However, despite the aforementioned shortcoming, Qi has earned the vote of confidence from tech giants like Google which is using the technology on its Android devices.
While it originally boosted on inductive charging, the Alliance decided in 2015 to merge with A4WP, the Alliance for Wireless Power. Thereafter, its working mechanism changed considerably.
As indicated by its name, Rezence uses resonant inductive charging which allows it to be more user-friendly than PMA. Even if you misalign the coils, your mobile won’t misbehave as it would otherwise do in the case of PMA.
Thus, while Apple Watches do operate on Inductive charging, Wireless technology hasn’t yet breached its smartphones.
Looking at the future and it is expected that the standard battle will wore on. The greater presence of Qi in the market means that you’re more than likely to encounter it on your next market visit.

How does it work?
If you ever attended a science class with concentration, it won’t be difficult for you to understand the working principle of wireless charging. It takes into account electromagnetic induction – a phenomenon which creates a magnetic field, from which generates a current that powers our mobiles.According to experts, the wireless charging method isn’t as effective as its traditional counterpart. However, for a normal person like me who has grown tired of searching for adaptor cables, this is a very minute shortcoming.
Another shortcoming – which will be overcome in the future, is the lack of distance between the charging device and your mobile. As this technology is still in its embryonic phase, you have to put your mobile over the wireless charging hardware so that it catches the signals.

The Benefits of Wireless charging
In addition to the obvious benefit that it will make our life “wireless”, the wireless charging will also make the environment greener. Being the users of traditional batteries, we know that the AAA, AA, or the D battery that we use have limited shelf life.That is to say, that after using them for a limited time, we have to throw them into the dustbin. Eventually, they become a part of the ever increasing landfill of mobile batteries.
However, when it comes to the wireless batteries, they have a huge shelf life. As a result, it would be a rare sight when you would see a person disposing of the wireless battery of his mobile. Therefore, complying with the Paris Accord, we’ll be polluting our planet even less.

Standards of Charging
Thanks to the embryonic phase in which the wireless charging is finding itself now, there is a host of competing and – incompatible charging standards in this field. Below mentioned are the two main charging standards.Qi
Although it was developed in 2008, the Qi Standard has earned fame in the last 1 to 2 years. However, don’t underestimate its worth as companies like Microsoft, Google, HTC, Samsung and Sony are its members.As reported above, Qi is based on the principle of electromagnetic charging. It comprises of tightly coiled wires which produce and receive the EMF. The Power which is taken up by Qi is 5W – which is surprisingly similar to its standard counterpart.

However, despite the aforementioned shortcoming, Qi has earned the vote of confidence from tech giants like Google which is using the technology on its Android devices.
PMA and Rezence
Founded by the partnership of P&G and Powermat Technologies, PMA was developed in 2012. While it is 4-years younger than Qi, the membership list of PMA is 80-members strong with companies like Microsoft, Motorola and even Samsung acting as its members.While it originally boosted on inductive charging, the Alliance decided in 2015 to merge with A4WP, the Alliance for Wireless Power. Thereafter, its working mechanism changed considerably.
As indicated by its name, Rezence uses resonant inductive charging which allows it to be more user-friendly than PMA. Even if you misalign the coils, your mobile won’t misbehave as it would otherwise do in the case of PMA.
The Future
One of the greatest hindrances in the path of Wireless charging is Apple. The U.S. based tech giant hasn’t introduced wireless charging for its smartphones.Thus, while Apple Watches do operate on Inductive charging, Wireless technology hasn’t yet breached its smartphones.
Looking at the future and it is expected that the standard battle will wore on. The greater presence of Qi in the market means that you’re more than likely to encounter it on your next market visit.
