Apple’s iPhone 12 can wirelessly charge twice as fast, but only with a MagSafe charger

Apple’s new iPhone 12 line will be able to access faster wireless charging speeds of 15W in line with the most up-to-date Qi standard, but there’s a catch: you’ll have to use Apple’s new MagSafe brand of charger or a MagSafe-compatible one from a third-party accessory maker.

Apple reintroduced its MagSafe branding for the iPhone with the announcement of its new smartphone line on Tuesday, and the company now touts a new feature in which “magnets align themselves perfectly every time for faster wireless charging” on its product page. But what Apple didn’t explicitly mention is that only its proprietary MagSafe brand, and not chargers using the general Qi charging standard it’s based on, can use those faster speeds.

Noted on the tech specs page for the new iPhone 12 line is a clearer breakdown that lists 15W for

Researchers developed a smart suit that is wirelessly powered by a smartphone

Researchers from NUS have developed a smartphone-powered suit that is capable of providing athletes with physiological data, including information on their posture, running gait, and body temperature while they are performing. The team says athletes are always looking for new ways to push human performance and to be able to improve the need to know their current limits objectively so they can overcome them. Current ways that athletes can track performance include wearables, such as the Apple Watch or Fitbit.

Better performing systems are available, but typically include tangles of wire and are too bulky to be used outdoors. The researchers sat about developing a system optimized for collecting data on athletes in the outdoor environment during performance using multiple sensors at different points on the body. One major goal was to reduce the system’s bulk, weight, and wires to an absolute minimum.

The researchers came up with a wearable
