What is Qi2.2 (Qi 2 25W), the new wireless charging technology for smartphones?
Table of Contents
The wireless charging standard Qi2.2 It arrived to provide new possibilities for recharging and using accessories on the back of our smartphones. Available since 2025 and now gaining more space in smartphones. AndroidSee how it works and, most importantly, what changes compared to the Qi2 standard.
Old patterns
Qi
With pronunciation “tchiThe Qi charging standard was first mentioned in 2009 by... Wireless Power Consortium (WPC). This charging standard works via a coil with charging power of up to 5W and a compatible device, such as a smartphone, smartwatch, headphone case, and more. Once the coil is connected to the power outlet or USB connection, simply place the device against it to receive the power.
Despite being revolutionary, the Qi wireless charging standard has faced many problems because it requires devices to be correctly aligned with the coil, and any movement on the table where it is placed can be a problem. Furthermore, due to overheating, the standard can cause long-term battery problems.
A Nokia It was one of the first to jump on the wireless charging bandwagon, bringing Qi technology to the market. Lumia 920. Samsung It came right after, in 2012, with the Galaxy S3But in that case, it only worked when using an official case from the brand. At the end of the same year, the Nexus 4, made by Google in partnership with LG, also adopted the new feature.
In the world of cars, the Toyota It took the lead by offering Qi charging as a factory option on the 2013 Avalon. Shortly after, also in 2013, the Ssangyong It became the second automaker to bet on this idea.
Qi2
Moving on to 2023, the WPC The company has updated its wireless charging standard to offer greater power. The big difference is that compatible smartphones and tablets can now receive up to 15W, increasing charging speed. Another major innovation is the magnetic rings, which ensure perfect alignment on the base and prevent energy loss during the process.
Despite the new name, the Qi2 is based on technology MagSafe da Apple. It is important to note that, although the pattern Qi2 Although recent, magnetic rings were introduced by Apple back in... iPhone 12The new standard has universalized this idea, using magnets to connect not only chargers, but also wallets, desk stands, and other accessories.
The iPhone 15 line was the first to be officially launched with native Qi2 certification. However, since the necessary hardware (the magnets) already existed in previous models, Apple was able to update the iPhone 13 and 14 via software to support the new standard. Within the ecosystem... AndroidManufacturers are working to integrate the magnets without causing interference with the internal components.
For devices that don't have built-in magnets, one solution is "Qi2 Ready" accessories. Basically, these are cases with magnetic rings. allow These devices are compatible with modern chargers and can take advantage of charging speeds up to 15W, although efficiency may vary depending on the model.
What changes with Qi2.2?
With the arrival of 2025, the wireless charging standard Qi2.2 (also known as Qi2 25WThis feature was introduced to offer more efficient recharging and solve overheating problems. Let's look at the main changes:
charging power
As the synonym says, the Qi2.2 The updated model now delivers wireless charging power up to 25W, the same limit as some brands such as Samsung They come with wired chargers. This way, charging will be faster without the need for cables, since only the magnetic rings will be used to keep the phone and the charger more secure. Which leads us to the next topic.
Best fit
Although magnets solved the alignment problem that slowed down charging, the original Qi2 standard still had room for improvement in efficiency. With the update, WPC refined the specifications of the... MPP (acronym for Magnetic Power Profile, or Magnetic Power Profile).
This optimization requires even more precise alignment between the coils, which reduces energy waste and improves heat dissipation, an essential factor for safely supporting higher power levels. In this way, devices with the new certification guarantee instant and perfect coupling, eliminating the need for manual adjustments by the user.
Heat management
To support 25W of power without compromising battery health, the Qi2.2 It adopts real-time communication between the charger and the device. Sensors continuously monitor the temperature, adjusting the voltage millisecond by millisecond to prevent overheating.
Furthermore, the energy efficiency of the new magnetic alignment reduces energy loss in the form of heat. It is worth noting that, to maintain a constant maximum speed, many high-performance Qi 2.2 chargers feature active cooling systems (silent fans) integrated into the base.
Compatibility with legacy standards
Like the standard Qi2.2 (25W) While this was only fully implemented in 2025, smartphones released before then, even those that already supported the original Qi2, remain limited to a maximum speed of... 15WIt's important to point out that using more powerful chargers or cases with reinforced magnets does not increase the charging speed of these older devices, as the power limit is determined by the phone's internal hardware.
However, the accessories are fully compatible: you can use a latest-generation Qi2.2 charger on an older model, taking advantage of the magnetic alignment, but respecting the device's original speed limit.
Devices compatible with QI2.2
iPhone 16 and iPhone 17
A Apple It pioneered the development of wireless charging, and as soon as the standard was recognized by the WPC, both the iPhone 16 line, released in 2024, and the iPhone 17 line, released in 2025, were already compatible with it.

Pixel Ring Stand and several Google partners are investing in new devices so that the MagSafe do Android Make it a reality, just like it's famously seen on iPhones.
Galaxy S26
Strong rumors suggest that the new Galaxy S26 line It will support charging. Qi2 25WHowever, there's an important caveat: the magnetic rings won't be built into the back of the device. Samsung's solution will be to use official protective cases equipped with the rings, allowing for the necessary alignment. Therefore, the devices, which are scheduled for release in [year], will be compatible. February 25, with sales starting from March 11They would be classified as "Qi2 Ready," depending on these covers to achieve the maximum wireless power of 25W.
Technology experts have even pointed out that the Samsung They even considered launching the Galaxy S26 line of devices with magnetic rings, but interference with the S Pen or reverse charging prevented it from going ahead.
