Apple introduced 25W wireless charging with the iPhone 16 ahead of the Qi2.2 specification being officially introduced early this year, which is why the faster rate was only available when using Apple’s own wireless charger. Now that the iPhone 17 lineup is Qi 2.2 compatible (as will most of the iPhone 16 lineup be once iOS 26 is released) the phones can be powered up at 25W rates using any wireless charger that supports Qi2.2. However, if you’re upgrading to the iPhone Air, you’re only going to see a maximum of 20W rates when charging wirelessly.
