The patents let iPhones use only the minimum power needed to work, and causes parts of the processor to turn off when they aren’t being used.
We’ve thought for a while that Apple was working on wireless charging for the next iPhone, and a recent patent filing reinforces that. What’s surprising is that the filing suggests the possibility of using a Wi-Fi router to transmit the power, but Apple’s not in that business anymore. Or are they? Jeff Butts thinks it might be too early to sound the death knell for the Airport router, and wireless charging might be the defibrillator needed to bring the device back to life.
