It was Palm who launched the first wireless charger, but now that Nokia has introduced one that will accompany the new Lumia range with Windows Phone 8 it has become "fashionable" again and some companies have reacted to it. One of them is Samsung, which according to it has communicated that it has begun with the mass production of this product that will be compatible with mobility-oriented devices.
Developed by Samsung Electro-Mechanics, this new product has to be placed inside the phone casing so that, in this way, it is able to receive power when it is necessary to recharge the terminal. The image is quite explanatory regarding how its design is and more or less be clear where it will be placed. The truth is that the design is quite suitable for models like Samsung Galaxy S3 to be compatible (something, on the other hand, that seems totally safe).
A development that seeks integration
As we have already indicated, the design makes it very clear that a basic design has been worked on that is compatible with Samsung's Galaxy models. But one of its fundamental characteristics, according to SamMobile -and it seems that this is what the company has indicated-, is that the element that is placed on the lid is a 40% thinner than any other currently used, since its charging coil is really thin… but very efficient.
For now the product is not for sale, but it is expected that its arrival will not take long to produce. We will have to see the terminal compatibility that Samsung already has on the market, since surely those to come will be. In addition, no information has been given about its price, and this is key to its rapid adoption in the market.
One of the doubts that arise regarding the use of wireless technology when recharging batteries is the Energy Efficiency at the time of work. Nothing is certain in this regard, but there are conflicting opinions as to whether it is worth your comfort if your capacity is not adequate. Would you use a wireless charger with your phone?
How this module works and what standard it uses
The Samsung module is based on electromagnetic induction and is compatible with the standard Qi of the Wireless Power Consortium. In this system, a transmitter coil in the base and a receiver coil in the phone transfer power when aligned. Qi operates in a range of typical frequencies 100 to 205 kHz and enables powers of up to 15 W with profiles such as EPP, incorporating temperature controls, foreign object detection and power regulation for greater safety.
The great advantage is that it offers wireless convenience and maintains compatibility with a wide range of certified phones, watches, and headphones. Even so, the centered alignment of the coil and correct contact with the base remain essential for optimal performance.
How to use the wireless charger correctly (step by step)
Before you start, it is a good idea to check that your mobile software is up to date: go to Settings> Software update, press Download and install and follow the on-screen instructions. With the system updated, follow these steps:
- Connect the base: Plug the power adapter into the wall outlet and the USB cable into the wireless charger. The base light usually blinks when you first plug it in.
- Place your device: Place your phone or compatible accessory (watch or headset) on the base.
- Align and center- Make sure the back of the device is in contact with the base and centered. On foldable phones, keep the phone closed and with the rear supported.
- Remove the cover if it is thick: Remove very bulky or metal casings to avoid loss of efficiency and heating.
If your Samsung mobile allows it, you can activate the reverse wireless charging (Wireless PowerShare/Battery Share) from Settings > Battery or Device Care, to charge another phone, watch, or earbuds by centering it on the back.
Compatibility, accessories and Galaxy ecosystem
The Samsung housing module is designed for the native integration with the Galaxy family and with Qi charging pads. In addition to phones, it supports accessories such as Galaxy Watch y Galaxy Buds on compatible bases. For fast wired charging, Samsung has adapters such as the EP-T4510 45W, which complement wireless use when maximum speed is required.
In the home and office ecosystem, there are options that expand the experience: Multi-output GaN desktop chargers (e.g. 2 USB-C + 2 USB-A with high total power), multiple sockets with master control to optimize socket usage, and 3-in-1 bases allowing you to charge your phone, watch and headphones at the same time with secure magnetic coupling.
Efficiency, warmth and good practices
In independent comparisons, wireless charging can show a 60-70% efficiency, below the typical >85% for cable. This explains why it tends to generate more heat may be somewhat slower. To improve results, center the device well, use Qi certified bases, remove thick/metal cases and avoid placing metal objects between the phone and the base.
If you notice high temperatures, opt for ventilated locations, avoid soft surfaces that block dissipation and consider deactivating the extreme saving mode If it limits charging power, for long sessions (like overnight), a standard Qi-certified base prioritizes convenience and battery conservation.
Trend-setting technologies and launches
The industry is moving towards more power and efficiency: Apple has incorporated magnetic wireless fast charging for watches with USB-C and has popularized 3-in-1 foldable docks for iPhone/Watch/AirPods. Brands like Lenovo have introduced laptops that accept high-power wireless input, proof that wireless charging is expanding beyond mobile devices.
On the desktop, vendors like Belkin are betting on High wattage GaN with multiple ports to charge multiple devices simultaneously safely and efficiently. Even charging solutions cubic sockets with master control help organize space and reduce competition for outlets.
At the heart of these advances is GaN: drivers like the ISL81806 Renesas's technologies simplify the use of GaN transistors in buck converters, raising the power density and reducing heat in chargers and compact power supplies. In automotive and dual charging, chips like the INJOINIC IP6566 integrate VBUS protection and switching for more reliable and simple designs.
In protocols, the jump to USB PD 3.1 enables very high power for laptops and stations, while solutions such as INJOINIC IP2736 y IP2133 (E-Marker for EPR cables) accelerate development and mass production. Industry leaders such as navitas They have deployed integrated GaN chips with control, protection, and actuation, with tens of millions of units shipped and a broad portfolio for mobile, consumer, and new energy markets.
Checks, useful apps and common questions
To find out if your mobile is compatible, check its official specifications and Qi database from the WPC. On Android, apps like Wireless Charging Checker confirm hardware support, and utilities like Ampere o AccuBattery help measure current and power during charging. On iPhone, all models since the adoption of Qi are compatible, and variants with MagSafe optimize alignment and power with certified accessories.
Remember: to start charging, you don't need to activate anything; just a connected Qi pad and the phone centered. If you use Samsung, you can enable fast wireless charging y Wireless PowerShare from the battery settings. In addition to mobile phones, they also charge wirelessly. auriculares, Watches and other Qi-compatible accessories. When purchasing, look for the Qi logo in the box to ensure compatibility and safety.
Samsung's commitment to mass-producing this module confirms that wireless charging is no longer an add-on, but rather another layer of the mobile ecosystem: it provides comfort, veteran connector wear and integrates with desktop and travel solutions, while GaN and PD 3.1 boost efficiency on the wired side. With best practices and certified accessories, the experience is stable and increasingly versatile.
