Apple’s “iPhone 13” may include a larger wireless charging coil than the iPhone 12, a rumor claims, one that could offer reverse wireless charging, as well as faster overall recharge times.
The MagSafe wireless charging system allows up to 15W of power to be delivered to a compatible iPhone, well above non-MagSafe wireless charging levels. However, Apple could increase those 15W to higher levels in the next generation of iPhone.
According to sources from Max Weinbach through AllApplePro, Apple could use a much larger wireless charging coil in the “iPhone 13”. The larger coil will increase the surface area of the region used for wireless charging itself, which provides a number of benefits.
This includes making it easier for the iPhone to manage component heat build-up, as well as allowing higher wattages to be used.
The size of the charging coil can also allow the iPhone to charge other devices in a reverse wireless charging mode. This could allow an iPhone to recharge products like an AirPods wireless charging case from the back of the iPhone.
In June, Bloomberg Sources claimed that Apple was interested in bringing wireless charging to the iPad Pro, and it could also include “bilateral” wireless charging at the same time. AirPower, Apple’s multi-device charging mat, which is apparently in the works too.
Apple has also been experimenting with high-performance wireless power technology. In 2017, Apple acquired startup PowerbyProxi, which offered a system that allowed 100 watts of wireless power to be transmitted with a 65mm coil.
