The world of wireless charging is witnessing a real and influential upgrade after years of limited development compared to fast wired charging. With the launch of the new QI2 standard, the upcoming smartphones became able to take advantage of the shipping speeds of up to 25 watts wirelessly, which represents a qualitative shift in daily use and restores attention to this technology.
What is the wireless Qi2 charging and why is it different from the previous?
QI2 is the new version of the QI, which is developed by the WAPC (WPC), and was officially announced in 2023, and its gradual spread began during 2024 and 2025, and Qi2 provides major improvements, most notably the increase in charging speed to 25 w This alignment guarantees an ideal convergence between the phone and the charger, which reduces the energy loss resulting from inaccurate positions, and also reduces the temperature of the device during charging.
Speed upgrade from 15 to 25 watts: a practical step
The most prominent improvement in QI2 is to raise the ability of wireless charging from the previous maximum of 15 watts to 25 watts, although this number does not match the massive wire charging speeds that have reached in some Chinese phones to more than 50 watts, it is a great leap compared to the first version, this speed allows fully charging a medium phone within about an hour, which makes wireless charging more possible use by the ordinary user.
Dependence on Magsafe technology from Apple for the benefit of everyone
Although Apple was not famous for the supernatural shipping speeds, its Magsafe technology provided a stable and stable wireless charging experience thanks to the magnetic alignment, and QI2 benefited from this concept by adopting what is known as the Magnetic Power Profile, allowing users to obtain the same experience even on Android devices, and that means that Coast compatible with QI2 will soon be able to charge iPhone phones, Android phones, wireless ear headphones with the same technology without the need for multiple chargers.
When does phones start to support QI2 actually?
Although the QI2 standard officially adopts its full support is still at its beginning at the level of Android phones, for example, the new Galaxy S25 series of Samsung supports this standard, but it is currently limited to only 15 watts, as it does not contain an internal magnet but rather needs a special external cover to activate the alignment feature, and likewise the modern Apple phones support the QI2 but at the same limited speed.
The real transformations are expected with future generations of phones from companies such as Xiaomi, OnePlus and others, which may provide real and complete support for magnets and alignment, and in return, manufacturers of accessories began to launch products compatible with Qi2 such as wireless chargers and magnetic pregnant women, which paves the way for broader adoption in the coming months.
