The increase in battery capacity in modern smartphones generates an increase in recharge time. To speed up the process, manufacturers are developing new technologies like QuickCharge, VOOC or PumpExpress. However, all of them are only designed to reduce the time spent on charging, but do not present anything radically new. Another development path is wireless charging. This promising direction, although slowly, is developing.

The convenience of wireless charging lies in the fact that you do not need to get tangled in wires and aim the cable plug at a small connector. The speed still leaves much to be desired, but you can recharge your smartphone by simply placing it in close proximity to a special source of electromagnetic radiation. Smartphones that support wireless charging and are relevant in 2016 will be discussed in the selection.

In February 2016, the company introduced a pair of new flagships, the Galaxy S7 and S7 Edge. Now they can be bought at a price of 550 and 600 dollars, respectively. Both smartphones feature a high level of performance, excellent cameras and support for wireless charging. They can replenish the battery capacity through Qi standard pads (more popular). The PMA wireless standard is also supported. In general, the devices are balanced and good in everything.

• Screen: Super AMOLED matrix, resolution 2560x1440 pixels, flat 5.1" (S7) or curved 5.5" (S7 Edge)
• Processor and Graphics: Samsung Exynos 8890 8-core + Mali T880 MP12 GPU, or Qualcomm Snapdragon 820 4-core + Adreno 530 GPU (market dependent)
• Memory: 4 GB RAM, 32 or 64 GB permanent + MicroSD
• Camera: resolution 12 MP, size 1/2.5", pixel size 1.4 µm, aperture f/1.7, DualPixel full phase autofocus), flash, OIS (optical stabilization), 4k video recording, front - 5 MP, f /1.7
• Battery: 3000 mAh (S7), 3600 mAh (S7 Edge)
• OS: Android 6

The combination of advanced functionality and premium design make these smartphones one of the best in 2016. Claims, by and large, they have nothing to present at all (except for a not very affordable price).

Samsung Galaxy S6 and S6 Edge are thin flagships

Despite the fact that Samsung Galaxy S6 and S6 Edge came out last year, they remain relevant in 2016. Now you can buy devices from $400 or $500, respectively. In addition to the top-end filling at the time of the presentation (which is still not listed as an outsider), smartphones received thin cases. Both models support Qi (Qi) and PMA fast charging.

Samsung Galaxy S6 and S6 Edge are powerful and well-balanced smartphones that you can now buy for normal money. Of the minuses, we can mention the lack of a slot for a flash drive.

LG Nexus 5 - compact ex-flagship

Three years have passed since the release of LG Nexus 5, but it is difficult to call it ancient. The smartphone remains relevant in 2016, although it is no longer able to compete with the flagships. It has an excellent display and a good camera that can beat some of the newer 13MP and 16MP models. LG Nexus 5 supports Qi wireless charging. You can find a smartphone now at a price of $ 160.

The smartphone is quite capable of arguing with the mid-budget 2016 (and surpass them). Of the minuses - the lack of a slot for a flash drive and a small battery.

Motorola Nexus 6 big screen phablet with stereo sound

The large Googlephone Motorola Nexus 6 was released 2 years ago, and as of the fall of 2016, it looks like a strong middle peasant. Large screen with high resolution, laconic design - these are the main advantages of the device. The smartphone supports Qi wireless charging. The price of the phablet at the time of compilation is from $270.

• Display: AMOLED, 2560x1440, 5.96"
• Processor and Graphics: Snapdragon 805, 4 cores + Adreno 420

Traditionally for Nexus, Motorola Nexus 6 has the main disadvantage - the lack of MicroSD. But the advantages of Motorola Nexus 6 include stereo speakers on the front panel.

LG G3 D855 - thin bezel phablet

Released in the summer of 2014, the LG G3 D855 is a flagship device at that time, or a mid-range device for the fall of 2016. Given that you can buy it now for $ 180, age does not matter by mobile standards. Moreover, the device has thin frames (the screen occupies more than 75% of the front panel), and is also equipped with a dedicated DAC and a Qi wireless charging module.

• Display: IPS, 2560x1440 pixels, 5.5"
• Processor and Graphics: Snapdragon 801, 4 cores + Adreno 330
• Memory: 2 or 3 GB RAM, 16 or 32 GB permanent + MicroSD
• Camera: 13 MP, 1/3", 1.12 µm, f/2.4, phase + laser autofocus, flash, optical stabilization, 4K video, front - 2 MP, f/2
• Battery: 3000 mAh
• OS: Android 4.4 upgrade to version 6

Thanks to the large screen with high resolution, compact (as for 5.5 ") dimensions and a good battery - the smartphone is still sold and has admirers.

Microsoft Lumia 950 - the last of the Mohicans

In 2016, fans of the Windows Phone OS were overtaken by the sad news: Microsoft stopped producing Lumia series smartphones. The latest flagship based on this system at the end of 2015 was the Microsoft Lumia 950. The device received the top-end hardware at that time and a Qi wireless charging module. Now you can buy Microsoft Lumia 950 by paying from $350.

• Screen: AMOLED, 2560x1440, 5.2"
• Processor and Graphics: Qualcomm Snapdragon 808, 6 cores + Adreno 418
• Memory: 3 GB RAM, 32 GB storage + microSD
• Camera: 20 MP, 1/2.4", 1.12 µm, f/1.9 Carl Zeiss, autofocus, flash, OIS, 4K video recording, front - 5 MP, f/2.4
• Battery: 3000 mAh
• OS: Windows 10 (Phone)

The Microsoft Lumia 950 is one of the best Microsoft smartphones of all time. For fans of the operating system from MS, who do not want to part with it, this is the best device.

Samsung Galaxy Note 5 is a slim phablet with a stylus

Released in the summer of 2015, the Samsung Galaxy Note 5, due to the unsuccessful release of the successor, in 2016 remains the last successful flagship in this line. The device is equipped with hardware that is still relevant today, a good camera, and also has a large front panel to display area ratio (76%). It is equipped with wireless charging that works with the Qi standard. PMA wireless charging is also supported. You can buy Samsung Galaxy Note 5 by paying from $570.

• Screen: Super AMOLED, 2560x1440 pixels, 5.7"
• Processor and Graphics: Exynos 7420, 8 cores + Mali T760 MP8
• Memory: 4 GB RAM, 32/64/128 GB ROM
• Camera: 16 MP, 1 / 2.6", 1.12 μm, f / 1.9, phase detection autofocus, flash, optical stabilization, 4K video, front - 5 MP, f / 1.9
• Battery: 3000 mAh
• OS: Android 5.1, Android 6 update

Among the advantages of the Samsung Galaxy Note 5, one can also note a dedicated DAC and a proprietary stylus, and the lack of a memory card slot can be added to the disadvantages.

*in fact, there are more smartphones that support wireless charging, and some of the list only support separately connected overlays with an "over-the-air" charge receiver. Find out about the smartphone you are interested in in the comments to this article. You can also expand this list by writing the smartphone model in the comments.

There are special adapters that you can purchase and build yourself under the cover of your smartphone and the device will support wireless charging. They are connected via contacts for the NFC antenna. You can see how it looks in the video after the list of smartphones that support such adapters:

• Samsung Galaxy S3
• Samsung Galaxy S4
• Samsung Galaxy S5
• Samsung Galaxy Note 2
• Samsung Galaxy Note 3
• Samsung Galaxy Note 4

There are similar adapters for the iPhone, but they are connected via a connector and have a small cable so that the cover with the charge receiver can be bent and attached to the back cover. However, the practicality of such a design is questionable.

In addition to such devices, you can find adapter cases for iPhones on the Chinese market with the ability to charge your smartphone wirelessly, but in this case you will have to sacrifice thickness.

There are options, like in the Jiayu G6 smartphone, which has an open adapter slot on the back cover. However, to use the wireless charger, you will need to purchase an original smartphone case.

Good day, dear readers. Samsung's wireless charging is what sets Samsung's smartphones apart from the competition, and especially from the iPhone. This South Korean giant is engaged in the production of various equipment, but has achieved particular success by developing smartphones. Their devices are manufactured using the most advanced technologies, bringing in millions of dollars in revenue every year. Not surprisingly, it was the Samsung Galaxy line of smartphones that was one of the first to offer the user to abandon the usual wired chargers. And, I must say, so far only a few companies have been able to compete in this regard with a company from South Korea.

Samsung - to be the first everywhere

It seems that it is difficult to connect the wire of a conventional charger, especially since today many smartphones are endowed with a USB Type -C port, which is symmetrical - you can connect the cable to the device on either side. And yet, manufacturers do not stand still, coming up with something new to simplify the life of the user. One of the latest “chips” of branded devices is wireless charging. Of course, it was not bypassed by specialists from Samsung, who did serious work on the technology. Of course, there were others before them, such as Nokia, which equipped the well-known Lumia line with support for wireless charging.

However, Nokia has left the ranks of the most advanced companies, and competitors have adopted the most interesting features of its products. Samsung, in addition to other interesting features, began to actively introduce wireless charging. She did this with a special approach, not just declaring a new "chip", but providing the user with everything that is needed for comfortable use. So, Samsung Galaxy s6 and s7, which received wireless charging, included a very stylish and high-quality charging stand. At that time, Apple - the main competitor - presented thick cases that were equipped with an additional battery.

Which Samsung models support wireless charging

The South Korean company had the idea to introduce wireless charging even before the release of the Samsung Galaxy S 3, which joined the ranks of flagships in 2012. However, then the idea was only in its infancy, and a prototype mobile phone with contactless charging was introduced by Palm OS. The Samsung Galaxy S 3 already had contacts for connecting the device using the Qi standard (located under the back cover). The next two models S4 and S5 were equipped with contacts, but wireless charging was not integrated. Special accessories came to the rescue, which made the technology quite working.

But the Samsung Galaxy S 6 with all its modifications, which brought a lot to the smartphone market, has already received a full-fledged wireless charging from the manufacturer. This model received an all-metal case, inside of which a coil is hidden, which serves as an energy receiver. The delivery set is accompanied by a docking station in the form of a platform that transmits energy. That is, the user just needs to put his Samsung Galaxy S 6 or S6 Edge on it to start charging. An interesting feature was that the smartphone supports wireless charging according to two standards at once: Qi and PMA. This allows you to use docking stations for various purposes.

More recent Samsung Galaxy S 7 and S 7 Edge solutions have not abandoned the innovative feature, which is not surprising. Wireless charging is also integrated in these models, and the package includes a pad. By the time the new product was released, many Chinese online stores were already inundated with original docking station solutions that are perfect for the Samsung Galaxy S7 and S7 Edge. Charging standards have remained the same - Qi and PMA.

The shelves are about to be replenished with the new Samsung Galaxy S 8 model. Several modifications with various innovations are expected. Wireless charging in the Samsung Galaxy S8, of course, is not new, but according to rumors, it will be seriously improved. According to a number of sources, the future flagship will receive an integrated receiver of three coils, which will significantly expand the reception range, increasing efficiency. It remains to wait quite a bit.

Principle of operation

Without going too deep, the principle of wireless charging for Samsung Galaxy, and other smartphones is the same. Two copper coils are used (transmitter - docking station; receiver - coil in a smartphone), which create a magnetic field. The receiver, receiving the waves, converts them into energy, charging the smartphone's battery. As a rule, the Qi standard (developed by the Wireless Power Consortium) is used, which supports the transmission of induction energy at a distance of up to 4 centimeters.

The idea of ​​transmitting energy "through the air" appeared about 200 years ago, when Marie Ampère proved that an electric current produces a magnetic field. Nikola Tesla also gave a lot of strength, who managed to light an incandescent lamp without wires. Of course, this technology has become interesting to electronics manufacturers in our time. Several corporations have developed their own standards for the transmission of small and medium currents. And more recently, in 2015, a group of scientists found out that energy can be transmitted via Wi-Fi. Apparently, the time is not far off when we will be able to completely forget about the regular recharging of devices.

Samsung Wireless Charging Galaxy - different models, different options

So, having talked a little about energy transmission standards, let's get back to the "guests" of our article. Considering that we are talking about wireless charging, the entire Samsung Galaxy line can be divided into two groups according to this principle:

Models with built-in wireless charging. This group includes:

• Samsung Galaxy S6/S6 Duos
• S6 Edge
• S6 Edge Plus
• S7/S7 Edge
• Galaxy Note 5
• Galaxy Note 7
• Watch – Samsung Gear S2 / Classic

Models for which a special receiver is available (there are special contacts under the rear cover):

• Samsung Galaxy S3
• Galaxy S4
• Galaxy S5
• Note 2
• Note 3
• Note 4
• Note Edge

Some other models that do not support any of the options shown support universal receivers. They can be purchased online at low cost.

Built-in wireless charging Samsung Galaxy S 6, S 7

Most lucky owners of the latest models Samsung Galaxy, which is already provided by the manufacturer for wireless charging. As a rule, a branded docking station is included in the package, which is suitable for charging other smartphones that have received this technology. By the way, the stand from Samsung is in great demand due to its versatility and high-quality assembly. If suddenly it breaks down, then you can buy a new one in almost any electronics store, as well as at a lower price in Chinese online stores.

Considering that the Samsung Galaxy S 6, S 7 models and their modifications use wireless charging that supports several standards, you can buy another docking station in a more stylish design. Today, there are hundreds of offers on the market that will definitely work with smartphones of the South Korean brand.

For recharging, it is enough to put the smartphone on the platform-transmitter. Do not forget to connect it to the electrical network using an adapter. The original docking station has a backlight that will notify the user about the progress of charging: blue color - the smartphone is charging; green - fully charged. The manufacturer has equipped the platform with an automatic shutdown function after the battery is fully charged. It plays a rather significant role, protecting the smartphone battery from destructive overcharging. Full charge time depends on the specific model (different battery capacities) - on average, it takes 3 hours to charge a 3000 mAh battery.

Wireless charging Samsung Galaxy S 3, S 4, S 5 - you need to buy something extra

As mentioned above, a number of Samsung Galaxy models (S 3, S 4, S 5, etc.) received special contacts that are "hidden" under the back cover. For each of the models, special receivers are presented (corresponding to the contacts), which are sold in online stores. They are inexpensive (about 700 rubles for a set with a docking station), they are connected very simply, hiding under the cover. These receivers are made according to the Qi standard, which allows you to use almost any platform for Samsung wireless charging (of course, also Qi).

It is most advantageous to buy such a receiver in Chinese online stores. The main thing is to look for which Samsung model it is intended for. It’s better to look under the smartphone’s cover on your own to understand how the contacts are located. Unfortunately, wireless charging still doesn't work well through cases, especially those made of metal, so either use thin cases or don't use them at all.

Universal wireless chargers

If someone remains faithful to their Samsung S 2, but wants to try out wireless charging, then they will have to buy a universal receiver. The fact is that at the time when this smartphone model came out, priority was clearly not given to charging without wires. The Samsung S2 doesn't have special pins like its descendants, but friends from China have found a way out. The universal receiver (it is a thin plate and a connector) is connected to the charging port, and the main part is bent to the back cover. Covers are used for fixation. Soldering iron virtuosos manage to connect the receiver directly, hiding it under the back cover. Docking stations come with the receiver, as a rule. However, any models that support the Qi standard can be used.

More expensive or cheaper

Of course, we all love to save money. However, when buying wireless charging for Samsung smartphones, it is better not to do this. This is especially true for the latest models. Although the manufacturer has already provided the original docking station for them, and you don’t have to worry about the receiver at all, many users want something new. Of course, no one is immune from the breakdown of the site, which entails additional costs. Give preference to branded wireless chargers from Samsung, well, or proven models: DT-900 from Nokia, Belsis TECs TS1001, interesting solutions from Woodpuck. By overpaying a little, you will reduce the risk of undesirable consequences: overheating of the site, power surges, overcharging, etc.

So what should owners of older Samsung Galaxy models do that didn't get wireless charging from the factory? Yes, almost the same thing - buy the original docking station. The receiver, of course, will have to be looked for from third-party manufacturers. If you decide to save money by ordering a cheap replica, then study user reviews that will help you set the level of quality.

Outcome

Wireless charging in Samsung smartphones is no longer just another feature that will interest only some users. Thanks to the responsible approach of manufacturers, the technology is becoming more popular day by day. Wireless charging points for smartphones from Samsung and other companies appear at airports, cafes, cinemas. Yes, wireless charging is far from a perfectly polished technology that has no drawbacks. They are, but every year the manufacturer solves them a little, bringing users closer to giving up a bunch of wires in the house.

Team A is back in action. At least when it comes to the company Samsung and a new reincarnation Galaxy A5 sample 2016 of the year . The smartphone wants to be like the S6, but it's much cheaper and has some premium features at the same time.

Models Galaxy A for 2016 is the answer Samsung on the tendency of Chinese manufacturers to release premium smartphones at the price of the average budget. This makes the smartphone a competitor OnePlus X and Xiaomi Mi 4c as well also an alternative Galaxy S6.

What is the new Galaxy A5 2016? Let's take a closer look.

Key features:

- available with a hybrid slot that allows you to use either two SIM cards or a SIM card and a memory card;

- a metal frame sandwiched between 2.5D and Gorilla Glass 4;

- 5.2-inch Super AMOLED display type with a resolution of 1080 × 1920 pixels and a density of 401 units;

- Snapdragon 615 octa-core processor (also available with Exynos 7580); 2 GB of RAM and Adreno 405 graphics chip;

– OS Android 5.1 with proprietary firmware TouchWiz;

– 13 MP main camera with automatic image stabilization and the ability to record video in 1080p;

- 5 MP front camera with 1080p video recording;

– 16 GB of built-in memory + 8 GB can be added via a memory card;

– fingerprint sensor and instant payment system Samsung Pay;

- 2900 mAh battery.

Main disadvantages:

– there is no possibility to record video in 4K or 1080p at 60 frames per second;

– limited memory space. There is no 32 GB version. But more depressing that you can only add 8 GB on a removable card;

– no MHL (but USB OTG is supported);

The whole summary boils down to the fact that it is necessary to compare this smartphone with the Galaxy S6, since the company is positioning this gadget as its replacement. And then it turns out that the smartphone is not quite up to par, although it received some bonuses in the form of MicroSD and FM radio, which the flagship does not have. But the camera received a lower resolution - 13 megapixels versus 16 megapixels. And 1080p video vs 2160p. The gadget also received a more capacious battery - 2900 mAh versus 2550 mAh, but lacked the ability to wirelessly charge. He also missed the screen resolution - 1080p, not QHD. But I got a slower chipset with less memory: 2 GB versus 3 GB. There is no heart rate sensor and blood oxygen sensor.

As a technical conclusion, it's hard to see why Galaxy A5 2016 should replace the Galaxy S6. This is a completely different phone, a lower level. The only thing better is the battery size. The camera is frankly weak, weak processor, little memory and RAM. Compared to the flagship of the first generation, of course.

This is despite the fact that the original 2014 Galaxy A5 was an ambitious project that offered an outstanding set of circuits at an affordable price. And the new smartphone only offers Samsung Pay. Internally, but externally, he has not changed at all.

Package

The Samsung Galaxy A5 (2016) offers a retail package of a 15W fast charger and MicroUSB 2.0 cable, as well as a three-button remote control headset. That is, nothing in the configuration has changed.

We take the Samsung Galaxy A5 (2016) in our hands and measure it with a ruler - 144.8 × 71 × 7.3 mm. Weight - 155 g. This makes it larger and heavier than the Galaxy S6. And the point is not even in size, but in weight - 138 g weighs S6).

Equipment overview

What is your favorite snack on a premium phone? Sandwich made of glass and metal as a body, of course! This is the most popular combo after the full metal jacket. So, the Samsung Galaxy A5 (2016) still received a new class of protective glass Gorilla Glass 4. The flagship S6 has the same one.

The metal sides are bevelled with small nubs on each of the four corners that improve traction and give a more secure grip on slippery surfaces.

The bezels around the screen are average, but Samsung's designers have created the illusion of very thin bezels. To do this, they used black glass and slanted metal sides to hide the extra thickness.

In the hand, the A5 (2016) feels like an impressive device. We are used to mid-range phones of this size being lighter in weight. It's not good or bad, just an opinion.

What's really good is the new screen resolution. The smartphone has been upgraded from 720p to 1080p. Add here the appearance of a fingerprint sensor on the Home button. Let this be the first wave sensor, the cheapest and not the most convenient, but now it is. It remains only to regret that it is not behind.

What's bad - the touch control keys have lost the possibility of long-term illumination. Apparently, in order to save battery power, which has already grown in volume. But they improved the capabilities of the selfie camera to help the user with night photos.

Beveled Gorilla Glass 4 on the front and back creates a beautiful curve that continues into the metal frame. The technology is now much more pronounced than on the Galaxy S6, and the phone feels better in the hands after this treatment.

On the sides are the standard power and volume buttons, as well as slots for a nano-SIM card and MicroSD. The metal frame is not very thick, which leaves little room for the buttons. They are narrow.

A slightly rough surface appeared on the back. The back is available in black, white, gold, or pink, while the front is almost always painted black (aside from the white version). The metal on the sides matches the back.

The 13-megapixel camera may not have an S6 sensor, but it does have its own F/1.9 wide aperture and auto image stabilization. And she doesn't stick out. One single-color LED flash goes into the bargain. There are no heart rate or blood oxygen sensors next to it, like the S6.

At the bottom of the phone is a microUSB 2.0 port and a loudspeaker (hidden behind a grill in drilled holes). There is also a microphone on the top and bottom – this pair is used for noise cancellation and stereo sound recording.

Final words

The result is a strange conclusion. The design of the Samsung Galaxy A5 (2016) turned out even better than the flagship S6, but inside the technical novelty is inferior to competitors who have long been able to shoot videos in ultra-high resolution and have QHD screens. So technically Samsung doesn't surprise the consumer too much in the middle segment. But if you need a beautiful phone, this gadget can be an excellent choice.

Nowadays, a person without a smartphone is a person out of touch with life. It is hard to imagine that a few years ago the mobile phone was used only for communication. Now this little helper gives us both access to the Internet and many applications, and wakes us up in the morning. The list of benefits provided by a smartphone is endless. It is not surprising that a large number of gadgets have been invented for modern phones. One of them is a wireless charger, which we would like to talk about in more detail.

How can I tell if my phone supports wireless charging?

From the name it is clear that this is a gadget that allows you to charge your smartphone without using wires. It is a small stand connected to the network. Inside there is an induction coil, which creates a small magnetic field around itself. If there is a smartphone within the radius of this field, it will receive electricity in the truest sense of the word through the air. But there is one caveat - the induction coil must also be built into the smartphone. It will serve as a kind of energy receiver from the charger.

The goal of creating this device was to get rid of modern smartphones from the charger connectors, as well as to allow all devices in the house to be charged from one platform. The idea was a success, but why then do we not see this technology in every home and do not use it ourselves? The answer is simple - despite all the advantages, this miracle device also has disadvantages.

Pros and cons of a wireless charger

There are enough advantages to wireless charging, but they all have their cornerstone.

No wires

Without a doubt, this is a big plus. Wires have always been a weak point in chargers. With frequent kinks, the wire was easily damaged and tangled. Frequent recharging loosened the USB port in the phone, and sooner or later a repair was required. But there is also the other side of the coin. The rejection of wires reduced the efficiency (coefficient of performance) from 90% to 60–75%. Simply put, when using wireless charging, your smartphone will charge for about 2-3 times longer.

Range of use

It would seem that there are no wires - there are no restrictions, and you can charge your phone just being in the apartment. But no - the range of using a wireless charger is very modest (3-5 cm) and the phone will have to be placed on a stand. Another significant drawback will be the impossibility of using a smartphone while charging.

Price

The cost of the charger is quite variable, but it will always be more expensive than the charging we are used to.

Standards

I would like to talk about the standards that made the use of electricity transmission technology over the air possible.

Qi ("Qi", in honor of the term of Eastern philosophy) was developed by WPC (Wireless Power Consortium - Consortium of Wireless Electromagnetic Energy). It is the most widespread and is supported by such giants of the mobile industry as Asus, Motorola, HTC, Huawei, LG, Nokia, Samsung, Blackberry, Sony and others. You can learn more about the standard and the list of supported devices on their official website.

The PMA standard also uses the principle of electromagnetic induction, but cannot boast as large a list of manufacturers supporting their technology as Qi. It was developed by Powermat, which is currently trying to fight unhealthy competition from Qi.

This standard uses Rezence technology, which is fundamentally different from PMA and Qi. The strange thing is that the most unpopular standard has many advantages over its competitors. The pluses include:

• the ability to charge through interference (if you put a book between a smartphone and a charger, nothing will change);
• one platform can power multiple devices;
• work in close proximity to metal objects, etc.

For a complete list of smartphones that can use wireless charging right out of the box, visit the official website https://www.wirelesspowerconsortium.com. I would like to note that most of the manufacturers made sure that their product supported the use of this technology.

What if your smartphone is not on the list of supported devices, but you need to use wireless charging? If you have such a question, then most likely you are a happy user of Apple products. So far, the iPhone does not provide the ability to receive electromagnetic signals. However, there is an alternative - the purchase of an auxiliary accessory that will do this for your phone. It fits under a standard case and does not cause any discomfort.

Is wireless charging harmful to health?

Like any new technology, the wireless charger raises a lot of questions. One of the most acute is whether it is harmful to health. Let's dispel this far-fetched myth. It will do you no more harm than an electronic shaver using the same technology. This is also claimed by the developers of the WPC standard themselves.

We hope our article was useful and helped you figure out the compatibility of your smartphone and wireless charger.

Do you want to know which Samsungs support wireless charging and whether your smartphone has this capability? Let's take a closer look at which Korean company phones support this wireless feature.

This company was the first to offer customers to charge their devices wirelessly, over the air. For the first time, this technology from Koreans appeared at various exhibitions a couple of years ago and Samsung still does not change itself. However, not every device of the company boasts the function of replenishing the battery charge by air. In this article, you will learn about all the models of the company with the implemented technology for transmitting energy through the air.

Samsung Wireless Charging Support: How Does It Work?

After looking at the main competitors from Apple Corporation, Samsung engineers decided to implement their own Qi interface.

In total, the company's smartphones have support for two standards - Qi and PMA. The first is newer and has a faster battery charge rate. However, it is found only in flagship devices that many users cannot afford.

What else is there besides Samsung - you will learn from another article.
