The battery case is a real salvation for users of modern portable mobile devices... Humanity has invented many useful things that make life easier and entertain us: telephone, TV, radio, music player, GPS navigator, computer, camera - all these devices have become an integral part of life modern man... Moreover, when all innovations are contained in one small palm-sized gadget, we inevitably become dependent on it. Yes, we are talking about a smartphone. In recent years, the developers of these personal assistants have made significant progress in the field of innovative technologies... In each new generation of the smartphone, more and more new functions appear, everything better screen, more powerful processor. Everything would be fine if manufacturers did not focus only on the performance and external components of mobile phones. Because of this, the autonomy of smartphones suffers, and the charging case for them has become simply an integral part. Indeed, most of the phones do not live up to the equator of the working day. State-of-the-art features, apps and powerful processors are powered by relatively weak batteries, which does not allow the owner of the smartphone to go far from the outlets.

What are charging cases for?

The accessory will make it easier and faster to solve the problem with a lack of power. Manufacturers are trying to please the tastes of customers by making smartphones thinner and larger screens. It is not yet possible to install in such devices powerful battery... And here the case-battery comes to the fore. Acquisition additional source energy is a step towards gaining freedom. The accessory is quite popular and will not be out of use soon. After all, power banks are significantly inferior to bumpers with a battery in convenience. This accessory may not always fit into a pocket with a gadget; you can simply forget it at home. Also, there is a risk of damaging the USB connector while charging your smartphone on the go due to carelessness.

The charging case is a more versatile and multifunctional accessory. It combines functions protective cover and an additional battery. Thus, acquiring such an irreplaceable thing, you kill two birds with one stone - increase the autonomy of the device two to three times and extend its service life, protecting it from scratches, falls, chips, dust, dirt. In addition, almost all models of battery chargers can provide protection from moisture and falls from serious heights.

How to use the case - battery

Before you buy a battery case, you need to know how to use it. Operating the portable charger is intuitive and convenient. It is enough to put the case on the smartphone and turn on the accessory with a single button. The battery level of the case can be identified by the indicator located, as a rule, on the back of the case.

A case with a built-in battery has a charge indicator that can be displayed directly in the interface, for example, as it is done in cases from the world famous Apple... Some flagship models start charging the smartphone only when the main battery reaches 0%. This is a huge plus as the battery undergoes less charge and discharge and does not wear out as much. The phone case with battery is very easy to charge, similar to regular phone, using the power supply and USB cable. The charging process of the case takes up to 4 hours, depending on the capacity of the battery, the size of which can reach up to 10,000 mAh. In the equivalent of smartphone autonomy, this is up to two to three days of independent use.

What are the other benefits of a portable battery case

In addition to the battery and protective functions, the charging cases have an excellent appearance... Manufacturers of such accessories have long refuted the myth that they spoil the appearance of mobile phones. Today you can find options with absolutely any pattern, in any color and from all possible materials. Moreover, the purchase will not be expensive. And if you need a charging case, the price won't be burdensome on your budget.

It is much easier to make purchases in our online store: our consultants will help you to cope with a huge selection of accessories, who will contact you and advise you on how to choose the right charging case for yourself.

The so-called wireless chargers for mobile devices have not been a sensational shortage in domestic retail for a long time. However, many manufacturers have yet to release their own wireless charging systems for their smartphones, and the popular Samsung Galaxy S3 is one of such devices.

In fact, even last year before the very release of the new flagship in the line of smartphones Samsung representatives several times mentioned the company's plans to release a wireless charger for the Galaxy S3.

But these promises have remained promises, and users have not yet seen the official Samsung aftermarket kit for the S3.

And it is very likely that they will not see it. The network is full of rumors and speculations about the future, and the long-awaited Samsung wireless memory will most likely start releasing for the new flagship. Wait and see.

However, if you already have an S3, and the desire to acquire just such a charger, without waiting for the manufacturer to please you with something more or less acceptable, both in terms of functionality and price, then there are also options.

Craftsmen, it turns out, have long come up with a fairly simple method. Now, adding wireless charging to your Galaxy S3 will take a little time, a little money, and a little bit of tidiness.

The proposed solution is based on a relatively inexpensive set for wireless charging of the not new Palm Pixi communicator.

Further point by point:

1. We collect the necessary parts and tools:

• Palm Touchstone charging dock (about $ 10 - hereinafter Amazon prices)
• Palm Pixi Touchstone back cover - Palm Pixi smartphone back cover ($ 3)
• AC adapter for Palm Pre and USB cable ($ 5) - this is important, similar devices from other manufacturers are not suitable
• adhesive copper tape
• Scotch.

2. Disassemble the back cover of Palm Pixi

Carefully peel off the black gasket on the back of the cover. You can do this simply with your fingers. Next, remove the silver sticker. Both parts - the gasket and the sticker - must be kept, they will be needed later.

After that, before tearing off anything else, you need to take a small piece of paper (kitchen parchment works great), cover the visible part of the diagram with it, and carefully, but carefully, mark the contours of the coil and the four metal discs surrounding it.

We put the resulting picture aside - it will also come in handy.

Now, using a knife, carefully separate the copper coil from the cover (in fact, these parts are precisely the elements of wireless charging) and four metal discs.

3. Installing the wireless charger components on the Galaxy S3

Remove the back cover of your S3. Place the parts removed from the Palm on the S3 cover: place the coil and L-shaped board in the same place and as shown in the picture.

Then, with a silver sticker, glue the coil on top. Now, guided by our drawing, we place all four metal discs around the coil, after which we fix their position with tape.

It is necessary to fasten the disks securely, since they are the ones that hold onto the base of the charger.

4. Connection

To the now modernized rear Galaxy cover S3 transferred the charge, it is necessary to correctly create the wiring diagram. To do this, we prepare four pieces of copper tape, each 5x25 mm in size.

On the L-shaped part of the board, we find two embossed terminals. We take one of the prepared copper ribbons, bend it about 5 mm from one edge and cover the upper terminal with the folded end, then stretch the rest of the tape to the edge of the lid at a slight angle and glue it tightly to the plastic (see picture).

In the same way, we make a bridge from the second terminal to the edge of the cover, but at a slightly larger angle. It is imperative to make sure that the copper tape fits well on both terminals. You can press the tape more tightly to the terminal using a regular pencil.

To the left of the battery on the smartphone case, we find a couple more terminals. We roll up the two remaining copper tapes from the ends in the same way as the previous ones, and carefully but securely glue them to the terminals and the body as shown in the picture above.

5. System check

We put the cover on the Galaxy S3 and place the device on the base connected to the mains. The indicator on the smartphone screen should show that the device is in charging mode. Working? Congratulations!

Now you can turn everything off, remove the lid again and glue the entire farm installed there, removed from the Palm with a black overlay (or black tape), so that everything is really beautiful.

If, after all the manipulations, the smartphone does not want to charge, then there may be several reasons for this:

• the ends of the copper tapes are poorly glued to the terminals (we check, we squeeze with a pencil or glue anew);
• a piece of tape on the lid touches the opposite tape on the terminal of the case (we check that the tapes on the lid are narrow enough and do not come into contact with both tapes on the case at once);
• the components on the cover are installed incorrectly (we check with the existing template, install the coil correctly, and then check the voltage at the terminals with a multimeter - it should be 5.5-5.6 volts).

It's all. By the way, in such a wireless way through the Touchstone base, your Samsung Galaxy s3 will charge much faster than from USB.

Although flagship smartphone the South Korean manufacturer is able to replenish energy without wires, most devices do not do this. All due to the fact that you need to buy a cover and an induction coil from a third party. But you can build it yourself in ten minutes. It is enough just to follow the instructions of the Cnet edition.

First you need to get an inductor from any phone with wireless charging. For example, from the old Palm Pixi. The back cover of a used phone will cost several dozen hryvnias, and you can buy it on the radio market or at mobile phone repair points. After that, you need to remove the sticker from it, under which the coil is located:

Next, you need to carefully remove the coil without damaging it:

Place the coil under the cover of the Samsung Galaxy S3:

Fix it securely with electrical tape:

With the help of pieces of copper foil, it is required to increase the contact area of ​​the coil:

Additional pieces of copper foil are required to increase the contact area in the Samsung Galaxy S3 itself:
After that, it is enough to close the lid and the phone will be able to charge wirelessly:

Remember: you make any modifications to your smartphone at your own peril and risk. The editors are not responsible for possible consequences. If you are not sure, buy a ready-made wireless charging cover from

Good day, dear readers. Wireless charger Samsung is what sets this company's smartphones apart from the competition, and especially from the iPhone. This South Korean giant is producing various equipment, but achieved particular success in 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.

Samsung - be the first everywhere

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 it with special approach, not just declaring a new "chip", but providing the user with everything he needs 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 covers that were equipped with additional element nutrition.

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 transfers 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 that are ideal for the 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 electricity 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.

Wireless charging Samsung 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 it comes 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
• Clock - 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 internet 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 colour- 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, 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 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 for which Samsung models it is intended. 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.
