Qi2 is a next-generation wireless charging standard that can reach 15W speeds, compared to 7.5W with regular Qi chargers.

iOS 17.2 previously enabled 15W Qi2 charging for iPhone 13 and iPhone 14 models.

Tests by Macworld found iPhone 12 now charges at 15W with a Qi2 wireless charger after updating to iOS 17.4.
