How Does Samsung Wireless Charging Work? (Revealed)

How Does Samsung Wireless Charging Work? With the inclusion of Qi wireless charging in Apple’s iPhone 8, iPhone 8 Plus, and iPhone X, wireless charging is set to become more popular.

It’s also found on Android phones, including the Galaxy Note 8, Galaxy S8, and Galaxy S7 from Samsung.

Most wireless chargers rely on magnetic induction and magnetic resonance on galaxy buds.

They promise the ability to place a device on a surface and have it charge automatically-no fiddling with cables necessary.

How to wirelessly Samsung charge your Phone and mobile device?

  1. First, connect the wireless charger’s power adapter to an electrical outlet, followed by the USB cord. The indicator light on the base will blink when the cable is initially connected.
  2. When ready, place your phone or compatible device (such as a smartwatch or earbuds) on the wireless charger.
  3. To ensure proper charging, the device’s back must be in contact with the wireless charger and be centered. Foldable smartphones should be closed, and their backs should face the charging pad.
  4. If necessary, remove your phone’s case, particularly if it is thick.


Of course, wireless charging isn’t truly wireless. Although your phone, smartwatch, tablet, wireless headphones, or other device does not need to be wired into the charger, the wireless charger or wireless power share must still be plugged into a wall outlet to function.

When Apple released the iPhone 5 without the wireless charging feature found in competing Android and Windows phones at the time, Apple’s Phil Schiller argued that “having to create another device you have to plug into the wall is actually, for most situations, more complicated.”

Apple changed its mind five years later. Apple includes wireless charging like a Samsung wireless charger who supports for the Qi open standard in the iPhone 8, iPhone 8 Plus, and iPhone X. (It’s pronounced “chee” because it’s a Chinese word for “life energy” in living things.)

Magnetic induction is commonly used in wireless chargers. To put it simply, they use magnetism to transmit energy. First, place the device, such as a smartphone, on the wireless charger. A magnetic field is created when the current from the wall power outlet flows through the wire in the wireless charger galaxy watch.

The magnetic field induces a current in the coil that is charging wirelessly inside the device. This magnetic energy is transformed into electrical energy, which is then used to charge the battery. To support wireless charging, devices must contain the necessary hardware- a device without the necessary coil that cannot charge wirelessly.

Originally limited to magnetic induction, the Qi standard now includes magnetic resonance. This works similarly, but the device can be up to 45mm away from the wireless charger‘s surface instead of directly touching it.

This is less efficient than magnetic induction, but it has some advantages. For example, a wireless charger could be mounted beneath the surface of a table, and you could charge a device on the table. It also allows you to charge multiple devices simultaneously by placing them on a single charging pad.

The Qi charger does not consume the maximum power when not actively charging. Instead, it uses less power and, when a device is detected on the charger, it increases the energy output.

Wireless charging is becoming increasingly common and standardized. For the first time, Apple did not develop its own wireless standard. Instead, it chose to support the existing Qi standard, which is supported by many other devices.

However, Qi is not the only standard available. The Wireless Power Consortium-owned Qi standard is ahead, but it is not alone. The Powermat, or PMA, standard from the Power Matters Alliance comes in second. It, like Qi, employs magnetic induction. However, the two are incompatible. A PMA wireless charger cannot charge an iPhone.

However, some devices are compatible with both. Modern Samsung devices, such as the Galaxy Note 8, Galaxy S8, Galaxy s6 and Galaxy S7, support both the Qi and PMA charging standards and can charge using either Samsung wireless powershare. Starbucks bet on PMA, but now that the iPhone only supports Qi, they may reconsider. Apple is betting that airports, hotels, and other public places will follow suit.

Instead, the Alliance for Wireless Power’s Rezence uses magnetic resonance, which Qi later added. This allows for more positioning flexibility. You can charge multiple devices on a single charger, move devices around, and even charge devices by placing an object between the device and the charger, such as a book. Rezence communicates with the device via Bluetooth.

The Power Matters Alliance and the Alliance for Wireless Power, which came in second and third, have since rebranded as the AirFuel Alliance and are working together to take on Qi.



Aside from the technology, getting started with wireless charging is fairly simple. You’ll need a smartphone that supports wireless charging and a compatible wireless charging mat to place your phone on if you want to charge it wirelessly. Adapters can also be purchased to add wireless charging support to phones that do not already have it.

Wireless charging is supported by the following popular smartphones:

  • Apple iPhone 8, iPhone 8 Plus, and iPhone X
  • Samsung Galaxy Note 8 and Galaxy Note 5
  • Samsung Galaxy S8, S8+, S8 Active, S7, S7 Edge, S7 Active
  • LG G6 (US and Canada versions only) and LG V30
  • Motorola Moto Z, Moto Z Play, Moto Z2 Force, Moto Z2 Play (with wireless charging mod only)

In recent years, Android manufacturers have increasingly abandoned wireless charging. Only Samsung has kept it on its most recent flagship phones. Google, for example, does not offer wireless charging in its Pixel smartphone, despite the fact that previous Nexus phones did. With Apple’s support for the Qi standard, wireless charging on Android devices may become more common once more.


If your phone does not support reverse wireless charging, you can add it with a special phone case or wireless charging adapter that you stick on the back of your phone and plug into the power port.

Once you’ve found a phone or adapter that supports wireless charging, find a wireless charger that works with it. A Qi charger is recommended for most phones. Any wireless charger that is Qi certified should work with any Qi certified device. They are available online at websites such as and in electronics stores. Plug in the charging pad and charge your phone (or other Qi-enabled device) on it. It will simply work as long as your device and charger support the same standard.

Wireless chargers will hopefully become more common in public places in the future, allowing you to place your smartphone on a table to charge it simply.

How do I turn on wireless charging on my Samsung?

Turn on Fast Wireless Charging. This can be found in your battery settings. The location may differ from model to model. It’s under Settings -> Device care -> Battery -> Charging on my Samsung phone.

What is the process of wireless phone charging?

Wireless chargers generate a magnetic field that your phone, watch, or other device absorbs in order to gain energy. When you place a device on a wireless charging pad, a small coil in the device receives and harvests magnetic field energy, which it then uses to power the battery.

Does Samsung work with wireless charging?

The Galaxy S20, S20+, S20 Ultra, Z Flip, Note10, Note10+, Fold, S10e, S10, S10+, Note9, S9, S9+, Note8, S8, S8+, S7, S7 edge, Note5, S6 edge+, S6 edge, and S6 support wireless charging. Learn more about Galaxy on your own. *Wireless charger not included.
