Historian and programmer. Applicant for the degree of candidate of historical sciences. He is passionate about high technologies and the development of the mobile industry. After all, this is a historical process that is taking place before our eyes at an incredible speed. Even computers have failed to reach the masses as quickly as smartphones. A few years ago smart phone was a huge rarity, and today almost everyone has it. And I want to talk and talk about this technological miracle, catching every moment of this amazing post-computer era.

Energysquare is a startup from France that has offered a very interesting technology allowing to carry out wireless charging almost any device. The development of the company was shown on. Wireless chargers have already gained some acceptance and are supported by a number of smartphones. But many users would like to find this innovative opportunity without changing their device. And now a technological solution that fulfills this dream has been created!
Shown by startup Energysquare at CES 2017, fast charging technology is compatible with almost all modern devices. It is a set of five very thin stickers that work in conjunction with a wireless charging mat.
Each sticker contains two electrodes and a Micro-USB, USB-C or Lightning connector that plugs into the device's charging port. After placing the stickers on the back of the device, the user just needs to place the device on the wireless charging mat, and the energy will start flowing into the smartphone or tablet.
Energysquare has used in its development an innovative conductive charging technology that allows you to simultaneously charge multiple devices. The user can easily put three or even four smartphones to charge on one mat. Charging devices will be carried out at approximately the same speed, which is usually typical for these devices.
The only noticeable drawback of this design is that the sticker blocks the charging port of the device. If the user wants to charge it in the usual wired way, he will have to disable the innovative sticker. This flaw in the proposed technology solution is known to Energysquare and the company is going to fix it by adding a rear port in the second generation of its products.
Deliveries of new gadgets may begin in the first quarter of 2017 at a price of $ 89. And then a huge number of devices that do not support wireless charging technology today will become compatible with this one of the most interesting and promising technologies of our time. After all, much of what is shown at CES further determines the development of the technology industry for the whole year. How attractive is the technology solution presented by Energysquare?
Good day, dear readers. Wireless charging Samsung- what distinguishes the smartphones of this company from competitors 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 technology, generating multimillion-dollar revenues every year. Not surprisingly, the ruler Samsung smartphones Galaxy was one of the first to suggest 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.
It seems that it is difficult to connect a wire of a conventional charger, especially since today many smartphones are endowed with USB port Type –C, which is balanced - you can connect the cable to the device either side. And yet manufacturers are not standing still, coming up with something new to simplify the user's life. One of the latest features of branded devices is wireless charging. Of course, it was not bypassed by specialists from Samsung, who carried out serious work on the technology. Of course, there were others before them, for example Nokia, which equipped the famous Lumia line with wireless charging support.
However, Nokia left the ranks of the most advanced companies, and competitors adopted the most interesting features of its products. Samsung, among others 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 a comfortable use. So, Samsung Galaxy s6 and s7, which received wireless charging, came with a very stylish and high-quality charging stand. At that Apple time- the main competitor - represented thick cases, which 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 just being born, and the prototype mobile phone with contactless charging, Palm OS was introduced. The Samsung Galaxy S 3 already had contacts for connecting a device according to the Qi standard (they were under 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 workable.
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 which a coil is hidden, which serves as a receiver of energy. The scope of delivery 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 is that the smartphone supports wireless charging according to two standards at once: Qi and PMA. This allows the use of docking stations for various purposes.
More recent solutions Samsung Galaxy S 7 and S 7 Edge 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, which are ideal for Samsung Galaxy S7 and S7 Edge. Charging standards remain the same - Qi and PMA.
The counters are about to be replenished new model Samsung Galaxy - S 8. Several modifications with various innovations are expected. Wireless charging in the Samsung Galaxy S8 is certainly not new, but rumor has it that it will be heavily refined. 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. It uses two copper coils (transmitter - docking station; receiver - coil in a smartphone), which create a magnetic field. Receiving waves, the receiver converts them into energy, charging the smartphone's battery. Typically, the Qi standard (developed by the Wireless Power Consortium) is used, which supports the transfer of inductive energy over distances of up to 4 centimeters.
The idea of transmitting energy "through the air" appeared about 200 years ago, when Marie Ampere proved that electric current produces a magnetic field. Nikola Tesla also put a lot of effort into lighting an incandescent lamp without wires. Of course, this technology has become interesting to electronics manufacturers already 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 times are not far off when we will be able to completely forget about regular recharging of devices.
Samsung Wireless Charger Galaxy - different models, different variants
So, having talked a little about energy transmission standards, let's return to the "guests" of our article. Considering that we are talking about wireless chargers, all Samsung line Galaxy according to this principle can be divided into two groups:
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 produced (special contacts are provided under the back 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 from online stores at low cost.
Built-in wireless charger for Samsung Galaxy S 6, S 7
The most fortunate owners of the most latest models Samsung Galaxy, in which the manufacturer already provides wireless charging. As a rule, a proprietary docking station is included in the package, which is suitable for charging other smartphones that have received this technology. By the way, Samsung's stand 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 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.
To recharge, just put your smartphone on the transmitter pad. Do not forget to connect it to electrical network via the adapter. The original docking station has a backlight that will notify the user about the charging progress: blue - the smartphone is charging; green - fully charged. The manufacturer has equipped the platform with the function automatic shutdown after the battery is fully charged. It plays a rather significant role, protecting the smartphone battery from destructive overcharge. Full charging time depends on specific model(different battery capacities) - on average, it takes 3 hours to charge a 3000 mAh battery.
Samsung Galaxy S 3, S 4, S 5 Wireless Charger - Something Needed to Buy
As mentioned above, the series Samsung models Galaxy (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 kit with a docking station), they are connected very simply, hiding under the cover. These receivers are made according to the Qi standard, which allows using almost any platform for wireless charging of Samsung (of course, also Qi).
The most profitable of all such a receiver can be bought in Chinese online stores. The main thing is to look at which Samsung model it is intended for. It is better to look under the cover of the smartphone 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 ones or skip altogether.
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 wireless charging. Samsung S2 does not have special contacts like its descendants, but friends from China have found a way out. The universal receiver (represented by a thin plate and a connector) is connected to the charging port, and the main part is folded over to the back cover. Covers are used for fixing. Soldering iron virtuosos manage to connect the receiver directly, hiding it under the back cover. Docking stations are usually included with the receiver. However, any model that supports the Qi standard can be used.
More expensive or cheaper
Of course, we all love to save. However, on the purchase of 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 an 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 insured against damage to 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.
What should owners of older Samsung Galaxy models do that didn't receive wireless charging from the factory? Yes, almost the same thing - to buy an 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, which will help establish the quality level.
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 points for recharging smartphones Samsung and other companies appear in airports, cafes, cinemas. Yes, wireless charging is far from a perfectly polished technology that has no downsides. They are, but every year the manufacturer solves them little by little, bringing users closer to abandoning a heap of wires in the house.
Samsung? That's right, high-performance video chips. This is cool, as it opens up many possibilities, but at the same time the power consumption of the gadget increases.
Now you will say that along with the improvement of the models, the capacity of the batteries has also increased, the dimensions have grown, and therefore the charging time has increased. Alas, we must disappoint you, this did not give a big breakthrough.
But do not worry, the manufacturers have tried their best, and the new models have a function fast charging from samsungs! In addition, an additional innovation has become a unique wireless charging, which eliminates the need to be constantly “tied to a power outlet”.
How does such a function work and what are its features? Now you will find out about everything!
Energy losses are minimized!
Especially for models such as the Edge Plus and Galaxy Note 5, such a unique wireless device- Qi charging. In its lower part there are several ventilation holes that cool the system.
Plus - there is a fan in the middle. All this allows you to quickly and easily recharge smartphones in any conditions.
Regarding other models of gadgets, then the developers have gone further. As you know, in principle, any work rechargeable batteries an electrochemical process is laid. It is he who gives and accumulates energy.
To prevent phones from draining quickly and keeping energy in them for a longer time, lithium-based batteries began to be produced. They are responsible for the "fast charge" mode.
When connected, energy is emitted from charger maximum power in the early stages. This means that your smartphone is charging as quickly as possible.
Advantages
This function can be disabled or enabled. When charging from a cable for only 10 minutes, the gadget remains secured for four hours autonomous work... Agree, earlier this could only be dreamed of!
Earlier expensive wireless charging is now available to everyone. Since it is sold together with a kit for some Samsung smartphones. Wireless charging technology also supports any other device.
To find out if your phone supports this innovation, do the following:
- Go to the "Settings" section.
- Open the "Battery" section.
- Check if an app is listed that is using the entire battery.
- The application can be used or disabled.
We can definitely say that the “fast charging” function has made the phones of the famous company even more advanced, cool! Competitors are clearly biting their elbows.
And we can only say: "Bravo!" developers and expect new technological breakthroughs from Samsung!
More recently, there was a time when the first cordless home phones needed to be charged from a large docking station, and it took a long time. Today modern smartphones can be charged without being connected to any wires. This is what high technology means. Of course, the choice of such devices is still not great, because the implementation of such a system in a phone costs a lot, so we have compiled a rating best smartphones with wireless charging in 2017, which reviewed the most popular devices on the market equipped with this technology.
Microsoft Lumia 950 XL
Our rating is opened by a new product of 2017 from Microsoft - the flagship Lumia smartphone 950 XL. This device is equipped with everything that a person can dream of: a thin aluminum body, a large 5.7-inch AMOLED display, Quad HD resolution. The phone features Corning Gorilla 4 tempered glass, which provides reliable protection from scratches and dirt. A high-quality, high-contrast and rich screen consumes a lot of energy, so the manufacturer equipped the smartphone with a good 3340 mAh lithium-polymer battery with a wireless charging module.

The speed of the system is provided by a comfortable 3 GB of RAM. There is plenty of space for the system and files in the phone: 32 GB will easily fit the necessary information.
LG G3 D855
The next in the top 5 smartphones is the phablet from LG. The company, of course, is far from the most popular in the world of phones. She nevertheless gained great fame in the field household appliances... However, if you want to choose reliable smartphone with wireless charging, the G3 D855 is one of the best contenders. The phone, among other things, is equipped with an unmatched 5.46-inch QHD-screen with a resolution (2560 × 1440). The battery, of course, is designed for only 3000 mA / h, but thanks to excellent optimization, it is enough for active use of 6 hours. On the battery capacity, the manufacturer, of course, saved for such a screen the capacity should be at least 4000-5000 mA / h, so as not to cause discomfort ...
- OS Android 4.4
- support for 1 sim card, micro standard
- internal memory - 16 GB
- pixel density 538 ppi

It is impossible not to pay attention to the optics: front-camera- 8 MP, rear - 13 MP, laser autofocus, optical stabilization, 8x optical zoom. It is better to assess its capabilities with your own eyes in a photo or video review of a smartphone. The performance of the gadget is also all right: Snapdragon processor 801 with 4 cores at 2500 MHz, Adreno 330 video chip, 2 GB of RAM. Such a filling will make it easy to use powerful games and applications. The body of the device is made of plastic with an imitation of metal, it is pleasant to hold in the hand.
Samsung Galaxy S6 Edge
Today, quite a few smartphones support wireless charging, but one of the "pioneers" in the production of such devices was the popular Samsung company. Galaxy S6 Edge is one of best phones for the last few year s. Refined style, aluminum body, safety glass Gorilla Glass 4 installed on the screen and the back of the smartphone will allow you to survive a fall without any consequences. The 5.1-inch AMOLED display curved around the edges, Quad HD resolution is the perfect set for a modern flagship. Of course, a smartphone with a good big screen and resolution must have a more capacious battery than lithium ion battery at 2600 mAh, but this is compensated by the fast charging function.
- Android OS 5.1, proprietary TouchWiz firmware
- support for 1 sim card, nano standard
- internal memory - 32 GB
- cameras - 16/5 MP, autofocus, optical stabilization, aperture f / 1.9

The technical side looks more than attractive. The main chip is an 8-core Exynos 7420 processor with a core frequency from 1500 to 2100 MHz, a graphics accelerator - Mali-T760 MP8, RAM - 3 GB. Such characteristics allow you to run the most demanding game on a smartphone without any display problems, with a 3D picture and sound. It is impossible not to remember in this aspect the curved screen, which gives an indescribable feeling of modern entertainment at maximum settings.
Xiaomi Mi Note
Whichever smartphone forum you look at, it's hard to find bad reviews about Xiaomi devices. Of course, you can find flaws in any phone, but considering the price-quality ratio of Mi Note, the language will not turn out to be a pretense. The build of this high-quality smartphone is excellent, with a screen diagonal of 5.7 inches and a resolution of Full HD. Its protection from scratches and damage is provided by a protective 2.5D glass. A distinctive feature of this model is a high-quality capacious 3000 mAh battery.

- dual SIM combined connector (mircoSIM + microSD / nanoSIM)
According to the characteristics, this chinese smartphone supporting wireless charging is also great. It received a high-performance Snapdragon 801 chip with 4 cores at 2500 MHz, as well as an Adreno 330 video accelerator. In addition, Mi Note has 3 GB of RAM in its arsenal, thanks to which the mobile phone works incredibly fast. The sensor works smoothly and supports up to 10 touches.
Samsung Galaxy S7
Today, many people want to buy a phone with wireless charging and dual sim cards. The largest manufacturer Samsung gives its fans such an opportunity. The Galaxy S7 is the best smartphone to date, no matter how you look at it. Its superiority begins, of course, with the design: a thin aluminum body, tempered glass, a function button. As for the display, the 5.1-inch AMOLED screen with 2560 × 1440 resolution offers an incredibly rich and clear picture. The battery is fine too: the 3000mAh lithium-polymer battery can last up to a day and a half thanks to a well-optimized OS.
- Android OS 6.0, proprietary TouchWiz interface
- cameras at 12/5 megapixels, aperture F / 1.7
- slots for 2 SIM, nano standard

Mobile phone with parameters better Galaxy S7 cannot be found. The top 8-core Exynos 8890 processor with a frequency of up to 2300 MHz with a Mali-T880 MP12 video chip in combination with 4 GB of RAM is fantastic performance and incredible smartphone speed, which is objectively hard to find equal. The only thing that, in our opinion, was not taken into account by the manufacturers is the installation of a microUSB connector, which, in our opinion, would be worth replacing with a more modern Type-C.
Conclusion
Our list of the best smartphones with wireless charging in 2017 gives only a brief idea of modern devices with such technology. Every year there are more and more such devices, the choice is wider and wider. Options are offered for every taste, so only an electronics lover can choose which smartphone to buy, taking into account his own requirements for the gadget and, of course, the budget. It should also be noted that this technology It is still developing and has not yet been fully developed, so it will take much longer to charge your gadget than if you were using regular wired charging.
Do you want to know which Samsung devices support wireless charging and whether your smartphone has this capability? Let's take a closer look at which phones of the Korean company have support for this wireless feature.
This company was the first to offer customers charging their devices wirelessly, over the air. For the first time, this technology from Koreans appeared at various exhibitions a couple of years ago and still Samsung does not change itself. However, not every device from the company can boast an over-the-air battery recharge function. In this article, you will learn about all the models of the company with the implemented technology of energy transmission through the air.
Samsung wireless charging support: how does it work?
After looking at the main competitors from Apple, Samsung engineers decided to implement their own Qi interface.
Let's figure it out,. The device must be connected to the network and located near your smartphone with a built-in receiver (you can read about which Samsung models support wireless charging below). A magnetic field is created between the phone and the device the moment the first is applied to the second. You don't have to activate any modules or run software- Samsung is able to automatically activate when touched. 
In total, the company's smartphones have support for two standards - Qi and PMA. The first is newer and more different. high speed filling the battery charge. However, it is found only in flagship devices that many users cannot afford.
Samsung Wireless Charging: Supported Models
Let's highlight a list of phones that support wireless charging from Samsung:
- for the first time, Qi support appeared already in the fifth generation of the Note phablet;
- generation galaxy S6;
- extended Galaxy version S6 Plus;
- curved version screen galaxy S6 Edge;
- the latest generation of the galaxy S7;
- galaxy S7 Edge version.
Now you know which Samsung phones support wireless charging and you can choose a device that suits your needs and capabilities. However, all the listed phones are flagships and their price tags differ slightly.
