How does Samsung wireless charging work? Principle of operation

How does Samsung wireless charging work? This is the question that worries many users of modern devices who are tired of the outdated principle of charging their phones using a cable.

Technologies for transmitting data over the air have appeared a long time ago and are now actively developing in the right direction, but the technology for transmitting energy through the air without the use of any wires still remains alien to many owners of mobile devices. In this article you will get acquainted with the principle of operation of wireless charging for a Samsung phone.

The principle of operation of the device

Important! Not all phones support charging with this gadget. Therefore, we suggest that you first familiarize yourself with the list of which Samsungs support wireless charging.

There are several interesting things about the charger:

• presence of its own cooling. If you disassemble the device, you can find a cooler in it, and on the case there are holes for the exit of hot air. This suggests that the Samsung wireless charger works even under heavy loads - the creators took care of this;
• the device is designed in such a way that the maximum speed of recharging the battery is achieved when the smartphone and the charging station come into contact;
• The branded device is compatible not only with Samsung phones, but also with any devices that have a Qi receiver.

How to use wireless charging

Samsung wireless charging works simply - additional software, installation of other additional equipment is not required. Algorithm:

1. Align the back panel of the smartphone and the center of the station. The display will show information about the estimated completion time of the process. Such times may vary and depend on conditions.

2. When finished, disconnect from power. The phone is charged and ready to use.

Precautionary measures:

• You should not place the gadget on the station in a case if it contains a card with a chip, radio tag, etc.;
• The procedure cannot be carried out if there is a current-conducting material between the device and the mobile phone: metal, magnet, etc.;
• It is recommended to use only certified stations. Operation of uncertified equipment may damage the battery.

Wireless transmission has also reached energy. Charging gadgets wirelessly is a convenient, fast option. Such stations look like a decorative element of the interior. The guarantee of stable operation is the use of Samsung branded products.

How to connect the device and improve performance

To enable wireless charging on Samsung, you do not have to install additional programs or connect modules. Flagship models, starting with the Galaxy Note 5, received Qi support. Thanks to cooling, it was possible to reduce heat generation. After all, the device heats up more than its predecessor due to faster operation. According to the company, the new product charges smartphones 30% faster than its predecessor. Connect the device to a power source and bring the smartphone to the front surface. The charge transfer will begin automatically.

Activate it on your Samsung mobile phone

The reality is that using reverse wireless charging is a feature that can be very useful for Samsung smartphone users. Mainly because it will allow you to share the battery with another device, be it yours or someone else's. Of course, it must be compatible with the type of wireless charging for it to work and not allow the other person to run out of battery.

However, in order to use this method on our Korean phone, we need to first enable the said technology on Samsung itself. Although it will be somewhat hidden, we will explain step by step how to get to its section. Therefore, if you want to activate this feature in your terminal, you must follow these steps:

1. Go to your phone settings.
2. Enter the Maintenance and Battery Section of your Samsung.
3. Click Battery.
4. Tap Wireless charging sharing .
5. Turn the switch that appears at the top.
6. Enable the feature by clicking on the toggle that appears, with which we can share the battery with another device.

By following the previous steps, you can use your mobile phone to transfer energy to another. Moreover, the same section in which we managed to activate this technology on our mobile device tells us how we should place the said terminals or any other gadget so that we can use this method in the best possible way.

One of the great advantages of this same menu is that it allows us to set a limit on the percentage of our smartphone's battery that we are going to share. Additionally, there is usually a default limit, but we can always change it depending on our needs. To do this, you will only have to click on this percentage and select the one you want to transfer to another device.

What smartphones can be charged using this system?

The operation of this technology is limited to those devices of the South Korean company that are compatible with Qi WPC wireless charging. So we can find that the Galaxy S series models from the S6 as well as the Note models from the Note 5 are compatible.

Therefore, in addition to these terminals, the Asian company itself cannot guarantee the compatibility of this technology with devices from other manufacturers. However, in principle there should be no problem as long as Qi Technology is among its components.

Advantages and disadvantages

Wireless battery charging technology is not just another unnecessary feature of a modern smartphone. The responsible approach of the manufacturer makes it popular among users of phones of various brands and models. Charging points for gadgets are appearing in public places. Manufacturers are gradually eliminating the need for numerous cables in the home for electronics buyers.

Wireless charging for mobile devices

The advantages of using wireless charging technology are:

• There is no need for a cable to connect the smartphone and the adapter. It is enough to replenish the battery capacity by bringing the gadget to a platform specially designed for this or by placing it nearby within a radius of 4 centimeters.
• Apple products allow you to charge multiple devices at the same time. Modern smartphone models require the purchase of an additional adapter when using this method of replenishing battery energy.
• Minimum number of cords and wires in the house.
• The docking station is convenient to carry with you. But you can also use transmitters from work colleagues or household members.
• No need to connect to the electrical network.
• Inability to forget to charge an electronic device.
• Receiver invisibility. Furniture manufacturers install docking stations in armrests, so the charger fits perfectly into the interior and does not take up much space.
• High speed of replenishment of battery capacity.

A huge advantage is the ability to quickly and conveniently place the device for charging. By placing the receiver on the kitchen table, coffee table or near the bed, and placing your phone there, you can constantly maintain the battery level at 90-100%.

The product connects to a smartphone without a special cable. In this case, the charging itself is connected using a wire to an electrical outlet.

Wireless charger

The disadvantages of products for replenishing battery energy include cost. They are usually more expensive than standard chargers. Their price is approximately 2-3 times higher. Despite this, this technology is attractive to users. Car charging is a practical solution.

Many people use electrical devices. Using products without wires to replenish the battery capacity allows you to quickly cope with the task. They do not harm human health, decorate the interior, and are convenient to use. A person who uses a smartphone will definitely appreciate a practical solution in the form of wireless charging, which can be taken with them to work or on a trip.

Apple devices

It must be said right away that Apple products do not support wireless charging technologies. However, the manufacturer is looking for alternative ways to provide this feature to its users.

In particular, he recommends using accessories in the form of cases from Duracell. Therefore, the question of whether wireless charging works through a case will have a positive answer in the case of iPhones. If this method does not suit you, then you can use an iQi format receiver card. It connects via a special Lightning connector and is also hidden under a standard smartphone case.

Devices from Cota

Cota employees are also developing interesting proposals. They are not just mastering the concepts of specialized charging panels for mobile devices, but are striving to expand their range of action as much as possible. For example, in addition to phones and tablets, such a device can fill wearable electronics with energy. Moreover, for this it is not necessary to bring the device close to the active panel.

A small device the size of a bread box works at a distance of 10 m. The question arises: “How does wireless charging work with such a radius? Is it effective enough? And here it’s worth returning specifically to wearable technology, including smart watches, bracelets and wristbands, since it is in working with these gadgets that the device demonstrates the most impressive performance. Obviously, batteries from phones and smartphones require more time to maintain.

Materials and build quality

The case is made of high-quality plastic, which does not make any unnecessary sounds during charging operation. The mechanism that underlies the folding design works perfectly - there are no complaints.

I really liked the surface of the adapter. It is very soft, so I don't worry about my smartphone getting scratched. It feels like leather to the touch, but it's actually not. Too little time has passed to understand how durable this material is, but I can say that in more than two months nothing has happened to it. There aren't even scratches.

Using a more premium material, such as aluminum, is not possible, since the metal interferes with the transmission of electrical current.

Important points when using reverse charging

Moreover, there are a number of points that we must consider when using this system with our mobile device. While it is true that this technology is effective, it is somewhat more sensitive to the wired method. Therefore, before you start using it, you should know that the phone you want to charge must also be compatible with the Qi wireless standard .

Another factor is that while the brand has come a long way in this section, the speeds aren't particularly fast, so you can't expect miracles when using this feature. In addition, we can only connect one device at a time and the use of this technology may affect both call reception and mobile data service.

It is also important to remember that if you have problems connecting both devices or the process is too slow, you will need to remove the covers, if any. And of course, to be able to use this wireless and reverse technology, both devices must be turned on .

Likewise, the device to which we want to transfer energy must necessarily be placed in the central part of the back of the Samsung smartphone. In case a few seconds pass and the process does not start automatically, we will have to recognize these devices again.

Tips for using Wireless PowerShare

Be sure to install your devices properly to ensure their connection is good. This is necessary because the location of the wireless charging coil varies by device. If you're trying to charge a foldable device using wireless PowerShare on your Note 20, make sure the other foldable device is closed.

More importantly, make sure your other device is compatible with Wireless PowerShare and supports this feature.

To view a list of compatible Samsung devices that can charge and share power using Wireless PowerShare, you can visit the Samsung support page. Most Qi-compatible Samsung devices are considered compatible, but charging speeds and power may vary between devices.

Directions for further development

Actually, all directions of development of chargers operating without wires are aimed at eliminating the above-mentioned shortcomings and generally improving the basic characteristics.

The considerable weight of such devices also remains a big problem. In the mid-segment, the average device is a platform that can hardly be called mobile. However, it is worth noting here how wireless charging works for the Samsung S6 and devices for younger versions of the smartphone from the Charger Kit line. These are panel charging accessories that are attached to phones like protective devices and cases. This interface configuration minimizes the size of the charging infrastructure, but is not highly efficient.

Flaws

Charging time

On average, wireless charging takes twice as long as wired charging. This is due to the fact that the current does not pass directly through the wire, but through the air, which reduces charging efficiency by 25 to 50%. Wi-Fi wireless network technology suffers from such a “cut” in speed: when connecting to the Internet via cable, the connection speed will almost always be higher.

Static position of the gadget

During charging, the gadget must lie or stand at the charging station in a strictly certain position. This happens because the induction coils of the devices must be opposite each other. Therefore, if the device is accidentally moved, charging will stop, and this is not always noticeable to the user.

Dimensions of the charger itself

A wireless charging station takes up extra space on the desk, and even though the phone or tablet itself charges wirelessly, the charger must be connected to an outlet or some other source of electricity.

Price

The price of a charging stand from a renowned manufacturer, such as Samsung or Belkin (products of this brand are recommended by Apple for its devices) is quite high. For Samsung chargers, the price starts from 4,000 rubles, and for the Belkin Boost Up Special Edition in the Apple store they ask for 8,431 rubles. In the middle price segment of devices you can find a charger for about 2000 rubles. Which is also not cheap compared to regular wired charging.

ATTENTION. Of course, there are very cheap chargers from China costing from 200 rubles. But the quality of such charging stations and their safety are questionable. It can damage the gadget or cause a short circuit.
