A5 wireless charging. Which phones support wireless charging: review, specifications and reviews

1. What is Qi wireless charging?
The world is becoming mobile and wireless.

In the modern world, all manipulations with file transfer using a smartphone occurs “over the air”. Access to the Internet via wi-fi - at home, at work, in cafes - is taken for granted, and rarely does anyone have difficulty using it. The time has come forwireless power transmission.

Was founded in 2008 " Wireless Electromagnetic Energy Consortium" (Wireless Power Consortium, WPC), which united manufacturers from Europe, Asia and America. The goal of the Consortium is to develop a unified standard for wireless charging technology.

Already in 2009 the company Palm provided the first phone with wireless charging support. Later, in September 2012, Nokia introduced 2 smartphones to the market - Lumia 820 And Lumia 920 also supports Qi standard. Next came the big smartphone manufacturers - Samsungg, Google Nexus(Asus, LG), Sony, etc.

Since 2014, our company Zaryadqi has been developing and distributing wireless chargers in Russia. Our store has the largest selection of wireless chargers and we are constantly monitoring new products and expanding our range. You will definitely find the right charger for yourself in our store.
2. Operating principle

In simple terms:
- The charger is connected to a power source.
- A magnetic field is created.
- The smartphone must support wireless charging - have a built-in receiver or an additional receiver.
- The phone is placed on the charger.
- Charging the smartphone starts automatically.
From a technical point of view:

Energy is transferred from the transmitter to the receiver through an interconnected magnetic field generated by the flow of alternating current through the transmitter coil.
If the receiver coil is in close proximity, a significant portion of the transmitter power lines will pass through the receiver coil, creating an alternating current in the receiver, which is then converted to direct voltage.
3. Benefits
Just. Place your smartphone on a Qi wireless charger and it will start charging automatically.

Modern. All major IT companies are already developing their devices using the Qi standard.

Versatile. Any device with a Qi receiver can be charged using any Qi wireless charger.

Safely. The generated electric field is safe for humans and extends only 1 cm from the device.

Comfortable and convenient. There is no need for a bunch of wires that later get tangled or simply lost.
4. Phone models that have a built-in receiver and support wireless charging out of the box

6. How to use wireless charging
7. Types of wireless chargers
We conditionally divide wireless chargers into several types based on functionality:
- . Standard charging stations in the form of a small “platform” on which the phone is placed, or charging built into equipment - a lamp, clock, weather station, etc.
- . Wireless charging for use in the car: with special holders and brackets for the phone and adapters for the cigarette lighter.
- . Wireless chargers with stand function, i.e. The phone is positioned at an angle during charging for easy viewing of videos, email, and social networks.
- . Wireless chargers with a built-in battery differ from each other, in addition to design, in the number of additional USB ports and battery capacity - from 4000 mAh to 10000 mAh.
- . Wireless chargers for installation in tables, cabinets, bar counters. They have a special design and protection from moisture and dust.
And also by scope or place of use:
- Home/office
- In the car
- On the road

8. There are receivers

Built-in- already installed in the smartphone by the manufacturer.

If the manufacturer of your phone does not provide the possibility of wireless charging, you can easily adapt it to this charging! For this, a special receiver film is used - there are several types:

In the form that is installed under the cover of the smartphone. To do this, your phone must have special contacts
, which connects to the lighting power port for Apple and micro-usb for Android smartphones.

Image	Description
	The film is attached under the cover of the phone, the functionality of the phone is not reduced. The standard cable can be used simultaneously with the installed receiver film. Such receiverQifor phones with special contacts Suitable for phones that have special contacts for wireless charging: Samsung Note 4, Samsung Note 3, Samsung Note 2, Samsung Galaxy S5, Samsung Galaxy S4, Samsung Galaxy S3 and others.
	The film is attached to the back surface of the phone. At the same time, it can be covered with any standard case: leather, plastic, silicone - this will not affect the charging process. The connector, inextricably linked to the film, for charging according to the Qi standard must be in the Lightning connector. Having a film receiver does not cause any inconvenience. Such Apple-receiverQi suitable for Apple devices with a Lightning connector: Apple iPhone 5, 5s, 5c, 6, 6s, 6Plus, 6SPlus, SE, 7, 7 Plus; iPad Air 2, iPad mini and others (Apple does not currently provide wireless charging without accessories)
	Such universal receiverQi Suitable for any phone equipped with a USB connector for classic wired charging. The film is attached under the cover or case of the smartphone. The plug, inextricably linked to the film, for charging according to the Qi standard must be located in the Micro-usb connector. Having a film receiver does not cause any inconvenience.

In phones with a Micro-USB port, the connector can be one of three types, depending on its type, if you place the phone on top of the screen.

Type C connector appeared relatively recently - it can be found on a small number of devices. Thus, type “C” is equipped with MacBook 12", Samsung TabPro S, Google Nexus 6P, Microsoft Lumia 950 XL, ZUK Z1, Google Pixel C, Google Nexus 5X, One Plus 2, Acer Aspire Switch 10 V and other devices.

In addition to the above receivers, depending on the location of the connector in the phone, such film-receivers may be suitable - they are called lateral or offset:

Accordingly, each type and position of the connector requires its own Universal receiverQi. By determining the correct type of Micro-USB connector in your phone, you will buy the right receiver for wireless charging and allow yourself to give up wires!

There are also: the receiver is already built into the case, so you just need to put the case on your phone and it will be able to charge wirelessly.

You can always tell the online store manager your phone model - we will select the optimal receiver for you!

9. Difference between wired and wireless charging
Wireless charging produces a current of 1 ampere and a voltage of 5 volts. The standard power adapter that comes with the smartphone produces from 1 to 2A. And when charging the phone from a computer (USB port), the phone is charged with a current from 0.5A (USB 2.0) to 0.9A (USB 3.0).

In this regard, you will not even feel the difference in charging time or it will not be significant.
9. Energy efficiency
Qi wireless chargers are approximately 80% energy efficient. It is worth understanding that it is simply impossible to achieve 100% energy efficiency; for standard wired chargers this figure ranges from 75% to 95% at best.
10. Security
Wireless chargers use non-ionizing frequencies that do not have harmful physiological effects on humans. The Qi 1.2 standard includes detection of foreign objects in the range of the charger, providing additional safety of use; Charging is only possible with Qi-compatible devices. Also, our chargers and smartphones have built-in safety mechanisms based on thermal control.

Still have questions?

The A-Team is back in action. At least as far as the company is concerned. Samsung and new reincarnation Galaxy A5 sample 2016 of the year . The smartphone wants to be similar to the S6, but it is much cheaper and at the same time has some premium features.

Models Galaxy A for 2016 - this is the answer Samsung to the tendency of Chinese manufacturers to produce premium smartphones at mid-budget prices. This makes the smartphone a competitor OnePlus X And Xiaomi Mi 4c, a also an alternative Galaxy S6.

What is 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;

– metal frame sandwiched between 2.5D and Gorilla Glass 4;

– 5.2-inch display with Super AMOLED display type with a resolution of 1080x1920 pixels and a density of 401 units;

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

– Android 5.1 OS with proprietary TouchWiz firmware;

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

– 5 MP front camera with the ability to record video in 1080p;

– 16 GB of internal memory + 8 GB can be added via a memory card;

– fingerprint sensor and instant payment system Samsung Pay;

– 2900 mAh battery.

Main disadvantages:

– it is not possible to record video in 4K or 1080p at 60 frames per second;

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

– no MHL (but USB OTG is supported);

The whole summary boils down to the fact that you need to compare this smartphone with the Galaxy S6, since the company is positioning this gadget as its replacement. And here it turns out that the smartphone falls far short, 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 versus 2160p. The gadget also received a more capacious battery - 2900 mAh versus 2550 mAh, but did not receive wireless charging capabilities. It also lacked 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 or blood oxygen sensor.

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

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

Package

Samsung Galaxy A5 (2016) offers a retail package of a 15 W fast charger and a MicroUSB 2.0 cable, as well as a headset with three remote control buttons. 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: 155g This makes it larger and heavier than the Galaxy S6. Moreover, it’s not even a matter of size, but of weight – the S6 weighs 138 g).

Equipment overview

What's a premium phone's favorite snack? A sandwich made of glass and metal as a body, of course! This is the most popular combo after the Full Metal Jacket. So, Samsung Galaxy A5 (2016) still received a new class of protective glass, Gorilla Glass 4. This is exactly the same as the flagship S6.

The metal sides are beveled with small knobs on each of the four corners to improve grip and provide a more secure hold on slippery surfaces.

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

In the hand, the A5 (2016) feels like an impressive device. We're used to mid-range phones of this size being lighter in weight. This is neither good nor bad, just an opinion.

What's really good is the new screen resolution. The smartphone has received an improvement from 720p to 1080p. Let's add here the appearance of a fingerprint sensor on the Home button. It may be the first wave sensor, the cheapest and not the most convenient, but now it exists. All that remains is to regret that it is not behind.

What’s bad is that the touch control keys have lost the ability to have long-term backlighting. 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 photographs.

The 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 there are 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 quite a bit of space 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 black (a departure from the white version). The metal on the sides matches the back.

The 13-megapixel camera may not have the S6's sensor, but it does have its own wide F/ 1.9 aperture and automatic image stabilization. And she doesn't stick out. One single-color LED flash comes in addition. There are no heart rate or blood oxygen sensors near it, like the S6.

At the bottom of the phone there is a MicroUSB 2.0 port and a loudspeaker (hidden behind a grille in drilled holes). There is also a microphone on the top and bottom - this pair is used for noise reduction and stereo sound recording.

Final words

The result is a strange conclusion. Design-wise, the Samsung Galaxy A5 (2016) turned out to be even better than the flagship S6, but inside the technical innovation is considerably inferior to competitors who have long been able to shoot video in ultra-high resolution and have QHD screens. So technically, Samsung isn't really surprising the consumer in the mid-range segment. But if you need a beautiful phone, this gadget can be an excellent choice.

Still have questions?

Good day, dear readers. Samsung's wireless charging is what sets this company's smartphones apart from its competitors, and especially from the iPhone. This South Korean giant produces various equipment, but has achieved particular success in developing smartphones. Their devices are manufactured using the most advanced technologies, generating multi-million dollar revenues annually. It is not surprising that 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 first everywhere

It seems that it is difficult to connect the wire of a regular charger, especially since today many smartphones are equipped 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 user’s life. One of the latest features of branded devices is wireless charging. Of course, it was not ignored by specialists from Samsung, who did serious work on the technology. Of course, there were others before them, for example Nokia, which equipped the well-known 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 other interesting features, has begun to actively introduce wireless charging. She did this with a special approach, not just announcing a new “trick,” but providing the user with everything they needed for comfortable use. Thus, Samsung Galaxy s6 and s7, which received wireless charging, included a very stylish and high-quality charging stand. At that time, Apple, its 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, at that time the idea was just in its infancy, and a prototype mobile phone with contactless charging was presented by Palm OS. The Samsung Galaxy S 3 already had contacts for connecting a 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, making the technology fully functional.

But the Samsung Galaxy S 6 with all its modifications, which brought a lot to the smartphone market, has already received full wireless charging from the manufacturer. This model has an all-metal body, inside of which is hidden a coil that 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 place his Samsung Galaxy S 6 or S6 Edge on it for charging to begin. An interesting feature is 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 solutions Samsung Galaxy S 7 and S 7 Edge did not abandon the innovative function, which is not surprising. Wireless charging is also integrated in these models, and the delivery 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 shelves are about to be replenished with a new Samsung Galaxy model – S 8. Several modifications with various innovations are expected. Wireless charging in the Samsung Galaxy S8 is, of course, 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. There's only a little time left to wait.

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 the smartphone), which create a magnetic field. The receiver, receiving the waves, converts them into energy, charging the smartphone battery. Typically, the Qi standard (developed by the Wireless Power Consortium) is used, which supports the transmission of inductive energy at a distance 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 in a lot of effort, managing 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 low and medium currents. And more recently, in 2015, a group of scientists found that energy can be transmitted via Wi-Fi. Apparently, the time is not far off when we will be able to completely forget about regularly recharging our devices.

Samsung wireless charging Galaxy – different models, different options

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, 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 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 presented do support universal receivers. They can be purchased in online stores at low cost.

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

The lucky ones are the owners of the latest Samsung Galaxy models, which already have wireless charging provided by the manufacturer. As a rule, the package includes a proprietary docking station, 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 build. If it suddenly breaks, 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 with a more stylish design. Today there are hundreds of offers on the market that will definitely work with smartphones from the South Korean brand.

To recharge, just place the smartphone on the transmitter pad. Don't 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 charging progress: 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. The full charging time depends on the specific model (battery capacities vary) - 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 lid. These receivers are made according to the Qi standard, which allows you to use almost any platform for wireless charging of Samsung (of course, also Qi).

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

Universal wireless chargers

If someone remains faithful to their Samsung S 2, but wants to try wireless charging, then they will have to buy a universal receiver. The fact is that at the time when this smartphone model was released, 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 (which is a thin plate and a connector) is connected to the charging port, and the main part is folded 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 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 money. However, it is better not to do this when purchasing wireless charging for Samsung smartphones. This is especially true for the latest models. Although the manufacturer has already provided an original docking station for them, and there is no need 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, 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, energy surges, overcharging, etc.

What should owners of older Samsung Galaxy models that did not receive wireless charging from the factory do? Yes, it’s practically the same thing – buy an original docking station. Of course, you will have to find a receiver from third-party manufacturers. If you decide to save money by ordering a cheap replica, then study user reviews that will help you establish the level of quality.

Bottom line

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 are appearing in airports, cafes, and cinemas. Yes, wireless charging is far from a perfectly polished technology that has no drawbacks. They exist, but every year the manufacturer solves them little by little, bringing users closer to giving up a bunch of wires in the house.

Nowadays, technology has become available that allows you to charge phones without using a cable. Its advantage is that this procedure is faster and easier, and you do not have to connect your smartphone to the network every time - you just need to place the device on top of the wireless charging pad.

There are various competing standards for this technology. The most popular of these is Qi, which is now supported by companies such as Samsung, Google and Nokia. However, more and more manufacturers are starting to use it in one form or another.

Which phones support wireless charging?

Some smartphone models have built-in wireless charging (their ratings are presented below). For other devices, this will require replacing the back cover or case. Qi components are produced based on specific phones, so if you connect them yourself, you should make sure that you choose a compatible model.

If a dedicated wireless charging cover is not available for your smartphone, you can use a universal adapter that allows you to use this technology even for older devices.

What do you need to know about wireless charging?

As noted above, the leader is currently the Qi standard, which is used in most Android devices today. The technology works by using magnetic induction, allowing energy to be transferred from the platform to the phone's battery. The Qi standard, whose name means “air” or “flow of spiritual energy” in Chinese, was created in 2008 and began to be developed simultaneously with the participation of 206 companies, including Microsoft, Samsung and Sony.

When talking about which devices support wireless charging, we should also remember the less common PMA standard. It also works due to magnetic induction, but its distribution range is slightly lower. In June 2014, the developers of the PMA standard partnered with Duracell to place charging platforms in select public places in the United States to promote the technology. If this idea proves viable in the future, it is possible that more smartphone manufacturers will start using this standard.

If we talk about which phone models support Qi-standard wireless charging, then the choice will be very large. Even if your Android smartphone doesn't have this technology built-in, you can purchase a universal Qi receiver that costs only about $15. Despite its bulkiness, it will add significant convenience to you when using the gadget. The device attaches to the back of your device, which can then be placed on any Qi-compatible charging platform. Regarding the question of which phones support Qi wireless charging, it is worth noting that there is a receiver available for sale for the iPhone (models 5, 5s and 6), which is also receiving positive reviews. Its cost is about $30.

Which phones support wireless charging (list of gadgets)

For those interested in the new technology, it will be useful to know the rating of devices that have built-in Qi standards.

The most famous model in this regard is the one that is currently available for around $200. According to user reviews, this is one of the best Android devices in principle. This device is also a leader in the use of wireless charging. The smartphone is compatible with both Qi and PMA technologies. Thanks to its sleek design, good speed and large 16-megapixel camera, this phone beats the iPhone in some ways. The commercially available Qi charger has a good long cable for connecting to the network. Its edges glow light blue while charging and turn green when charging is complete.

Among the devices that can be charged wirelessly are the following:

Samsung Galaxy Note Edge.
Samsung Galaxy Note 4.
Google Nexus 6.
Motorola Droid Turbo and others.

Other Samsung models

Analyzing which Samsung phones support wireless charging, one cannot help but remember that this model also simultaneously supports both standards - Qi and PMA. The attractive curved body shape and convenient screen allow owners to instantly access messages and other important data, and the built-in adapter does not impair the use of the device in any way. While the gadget itself can be purchased for about $300, the charging Pad costs about $40.

Also belongs to this category of devices. This smartphone with an innovative curved screen offers very strong graphics performance on a bright display. Its screen size is significantly larger than other devices, so battery drain is correspondingly faster. This model doesn't integrate wireless charging directly into the back of the phone, but there is a special Samsung Qi-enabled cover available on sale that replaces the standard back of the device. This accessory costs approximately $25 and is available in two color options: jet black and snow white.

If you ask which phones support wireless charging in general, you will notice that this technology mainly affects gadgets with high hardware capacities, for which the ability to quickly charge them is especially important.

Based on this, it is not at all surprising that it is also equipped with the described technology. This gadget is distinguished by high multitasking, fast and high-quality camera and high brightness of the 5.7-inch screen. In order to charge it wirelessly, you will need a special case. It's available for about $30 and comes in two colorways.

However, Samsung is not the only manufacturer using this technology on a large scale. What other brands of phones support wireless charging? Let's look at it below.

Other brands

Google Nexus 6 has an almost 6-inch screen and is equipped with a high-power processor, so it especially needs the ability to quickly and efficiently recharge. Qi technology is built-in here out of the box, so there is no need to buy an additional cover or case. This gadget is quite expensive - about $500, but fans highly appreciate its hardware capabilities along with Android 5.0. All this offers users a high level of comfort. Despite the fact that there is no special platform for wireless charging, the universal component will do the job perfectly.

When talking about which phones support wireless charging, we can’t help but mention a model like the Motorola Droid Turbo. This smartphone with a screen of just over 5 inches has a 21 megapixel camera and many built-in functions. Its battery life is approximately 9 hours during active use, so the built-in Qi technology is very useful. There is also a special charger for this model, which places the phone in a vertical position. This means that you can continue to use the device while charging.

Brand "Sony"

As already noted, the new technology is most actively used by manufacturers such as Samsung, Google and Sony. Which Sony phones support wireless charging? First of all, this is the Sony Xperia Z3 - a waterproof gadget that, with active use, lasts up to 12 hours without recharging. Its screen is highly bright, and its speakers provide loud, luxurious acoustics. Despite the fact that its cost is about $400, the device is widely popular. The wireless charging cover will have to be purchased separately, and it costs over a hundred dollars.

Is it possible to adapt your smartphone?

What phones support wireless charging without having the technology built-in? If your device does not natively support Qi, you can separately purchase and install an adapter on it and use a universal wireless charger. Depending on the brand of the gadget, you can connect the adapter via a micro-USB port (on the Android platform) or a lightning bolt (on an iPhone).

Universal wireless charging adapters

If your phone is not listed above, then you need a universal adapter and a wireless charger. You can get them for phones with micro USB ports (like Android) and lightning ports (like iPhone). In this way, you can update and improve almost all devices available for sale. If we talk about, for example, which Xiaomi phones support wireless charging, then with the above method you will be able to charge even 5-year-old models without a cable.

Universal charger

Once you've made sure that your phone supports wireless charging (either through built-in functionality, using a special cover, or by connecting an adapter - it doesn't matter), you'll need to purchase a wireless charger.

Nowadays, there are many such Qi technology devices available in different sizes, shapes and colors. You can buy such a component not only for use at home or in the office, but also for a car, and even a portable Qi battery. If you purchased a smartphone that supports wireless charging, it is advisable to choose a charger specially designed for it. If you don’t have one or you’ve updated your gadget yourself, finding a universal device won’t be difficult.
