It was with Samsung Galaxy S5 that Samsung rolled its wireless charging took it seriously with the Galaxy S6 and Galaxy S6 edge, following which every new flagship from the Korean giant has come with wireless charging support. The company released an official wireless charger to go along with the S6 lineup; Samsung then upped the game with the Galaxy Note 5 and Galaxy S6 edge plus, which introduced support for fast wireless charging. The Galaxy S7 and Galaxy S7 edge followed suit and were accompanied by Samsung’s new standing wireless charger. Now, Samsung is finally combining both its pad and standing wireless charger into one.
If you wish to know how wireless charging works then you need to first know and need two things that is a device with wireless charging capability and a compatible wireless charger. Plug the charger into a wall outlet and place your device on it to power up. It’s that simple.
For a more technical answer understand that Wireless chargers emit an alternating magnetic field via the transmitter coil, which in turn induces an alternating voltage/current in the receiver coil inside the device. Another thing to keep in mind when you buy a wireless charger is that it won’t charge up your phone as fast as a wall charger can.
You need to make sure that your phone supports such a charge. For some smartphones, you’ll need to buy a special replacement back or a case that enables wireless charging. You also have to check that the wireless charger you choose is the right standard for your device. The most popular standard right now by far is Qi, under the Wireless Power Consortium (WPC), but there is a rival called Powermat, under the Power Matters Alliance (PMA), which merged with the Alliance for Wireless Power (A4WP) to form the AirFuel Alliance, which is pushing a new standard called Rezence.
How does wireless charger work?
Wireless charging uses two coils of wire, one in the charger and one in the device itself. An alternating current passes through the coil in the charger, which generates a fluctuating electromagnetic field.
When the coil in the device is placed inside this electromagnetic field, a current is induced in the coil, which then charges the device’s battery. This is why wireless charging is sometimes known as inductive charging.
If you smartphone doesn’t come with wireless charging built in, you may be able to add the functionality with the help of a special phone case. This has the added advantage of also protecting your smartphone from damage – but you may find that a lot of the current wireless charging cases as there are several different wireless charging standards, all competing to be number one.
Top of the tree at the moment is the Qi system, which is backed by over 200 different companies, including Nokia, Google and LG. The Apple Watch has also been found to be compatible with Qi –although strangely, Apple hasn’t officially acknowledged this though.
However, you don’t need to worry too much about the different charging standards at the moment. As long as you use the charging pad that came with your device or case, you won’t have any trouble. With a wireless charger you don’t have to mess around with charging cables all the time. You just put your phone down on the charger and that’s it. Obviously, this is convenient – but there are other benefits too.
The wireless charging coils are completely sealed within the device, with no external electrical contacts, which means they’re completely protected. This is why inductive charging is often found in devices used in wet environments, like electric toothbrushes, where a standard charging socket would start to corrode. Some manufacturers, Sony in particular, have used this aspect of the technology to make some of their smartphones completely waterproof. Wireless charging does have its downsides, that it charges slowly as said above.
According to Verizon your smartphone must be Qi (pronounced “chee”) compatible; all wireless charging accessories sold by Verizon are Qi certified. Look for a Qi logo on the device or its packaging. The icon is easy to identify—a Q-shaped magnifying glass focusing on the letter ‘i.’ Qi wireless charging pads work with compatible smartphones, tablets, Bluetooth® headsets, cameras and smartwatches.
Also it depends whether you need to charge your smartphone in its case, or do I need a special case for it. The Droid Turbo 2 by Motorola, for example, can be charged wirelessly with any case on, but some older smartphones require a special device-specific wireless charging back cover (sometimes called an inductive charging cover). You can find this information in your device manual, at verizonwireless.com or on the manufacturer’s website.
So how to charge your phone, well despite the name, there is one wire involved: You must plug the charger into a wall outlet. But there’s no wire between the charger and your phone. Just place your phone on the charging pad and watch your device juice up. An indicator light lets you know when it’s charging.
The Galaxy S6 and GS6 edge, both of which have built in support for the Qi and PMA wireless power standards. In other words, the two GS6s charge wirelessly without any extra case or accessory.
Samsung released its own branded wireless charging pads. The round Samsung Wireless Charging Pad designed for use with the new Galaxy phones, but it also works with other Qi compatible devices and accessories, according to Samsung.
Samsung charges $50 for its new Wireless Charging Pad, which isn’t expensive, but it’s also not cheap. For example, you can get a generic, unbranded Qi-compatible pad for $7 on CellPhoneCases.com.
You need to use appropriate cable. Samsung says you can damage the charging pad if you don’t use the appropriate cable to charge, so don’t plan to use any spare cables you have around the office or at home.
