How does Samsung Wireless Charger Work?

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 Samsung galaxy series of new phones 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. The new wireless charger from Samsung is Trio Pad Wireless Charger.

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 you 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 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.

Advantages of using a wireless charger

There are advantages of wireless charging and using a wireless phone charger. Here’s why wireless charging may be a good choice for you.

  • With wireless charging, all you need is one cable plugged into the charging mat and no more multiple cables for multiple devices. Also the universal standard the Qi wireless charger  is compatible with all devices. So, wireless charging for iPhones is the same for Androids. You can use the same charging mat for all your devices.
  • All you need is to just place your phone face up on the mat and it starts charging.
  • Wireless charging mats have already started showing up at hotels, restaurants, and coffee shops. They are also more secure than plugging your device into an unfamiliar charging cable.
  • As there are no wires, you’ll get rid of the cables on your desk, bedside table, and in your car (in-car wireless charging is available too). Some furniture companies are even building wireless charging into their furniture, eliminating the need for a charging mat on your table or countertop.
  • Once the device is fully-charged, the wireless charger shuts off, resulting in saved energy, a safer charge, and less need to worry about overheating your battery.
  • When playing slots and games the battery is drained and wireless charger is easy to carry anywhere you want.

    Note that you can still use cables to charge your phone when you need to.

Disadvantages of wireless charger

  • Wireless charging typically takes 30-80% longer to fully charge your device than a cable. Also this depends on how you place your device on the mat can affect how long it takes to charge. Thus a slow process and not great in terms of conserving energy.
  • Your device has to stay on the mat while it’s charging, meaning you can’t pick it up and use it in the way you can when it’s plugged into a charging cable.
  • Wireless chargers are a relatively new technology with a hefty price tag, especially compared to cables. Depending on the size, they can cost anywhere between $40 and $100.

With the Wireless PowerShare feature, your phone can reverse charge another phone, watch, or Galaxy Buds. All you need to do is place the two devices together.

Note that the Wireless PowerShare works with most Qi-Compatible devices. This feature may not work with some cases, accessories, or other manufacturers’ devices.

How to activate Wireless PowerShare and charge another device?

You need to adjust the position of the devices to ensure their connection is good because the location of the wireless charging coil varies by device. Foldable devices will need to be closed. Using Wireless PowerShare may affect call reception or data services, depending on your network environment.

First, confirm that the phone with PowerShare is charged to at least 30%. Swipe down from the top of your screen with two fingers to open Quick settings, and then tap the Wireless PowerShare icon. If the icon’s not there, you may need to add the PowerShare quick setting.

Next, place the PowerShare phone and a compatible device back to back. To stop charging, just separate the two devices from each other. The PowerShare feature will automatically turn off after 60 seconds when no other device is detected.

You can also charge your Galaxy phone as it charges another device. Simply connect your phone to the charging cable that came with it while using PowerShare.
