Set your phone on a charging pad for half an hour and watch it jump from 0% to 50% battery — that's the real-world difference Qi2 25W delivers, and why it's often called "Qi2.2." When the spec was officially announced last summer, iPhone and some Android phones were already on the support list, but Google lagged a step behind. Only with the recently unveiled Pixel 11 series did Qi2 25W finally make it onto the spec sheet, letting the Android camp catch up at last.
The core difference comes down to the power number. The old Qi2 topped out at 15W, and charging speed depended on the device — going from 0% to 50% typically took about 50 to 80 minutes. Qi2 25W raises the ceiling to 25W, cutting that same 0-to-50% charge down to roughly 30 minutes. Wireless charging has long been seen as less efficient than wired, and this speed boost goes a long way toward closing that gap.
