Description:
Launching at the end of 2023, the newly dubbed Qi2 builds on top of Apple's MagSafe tech to boost charging speeds.

FULL STORY ======================================================================

The Wireless Power Consortium (WPC) is currently working on a follow up to
the Qi wireless charging standard, and in a nice change of pace, Apple is helping out by sharing its MagSafe technology.

Apple has been known to not always play nice with others as it appears to prefer to having total control over its environment and not share, much to
the chagrin of others . But now the tech giant is willingly allowing the WPC to use MagSafe as the basis of Qi2, as its called, in order to create a
global standard for wireless charging.

According to the announcement , the organization hopes to clear up any confusion concerning what devices are Qi Certified and those that claim to work with Qi but are not Qi Certified. The WPC goes on to say that this confusion can lead to a poor user experience and even safety issues. Educated guesses

At this time, the full capability of Qi2 is unknown. The standard is still a long ways away as smartphones and chargers that support it wont launch until the 2023 holiday season.

However, the WPC does reveal that at the center of Qi2 is the Magnetic Power Profile, which is claimed to ensure that phones or other rechargeable battery-powered mobile products are perfectly aligned with charging devices. As a result, users will experience higher energy efficiency and faster charging speeds. There is also the hope that wireless charging can expand to devices, like smartwatches, that dont work on typical flat surface chargers.

Despite the lack of information currently available, we can still make a few educated guesses. Considering Qi2 uses MagSafe tech, its possible upcoming chargers will utilize magnets to latch onto smartphones, feature charging speeds up to 15 watts, and come with foreign object detection. That last one is particularly important because it allows MagSafe chargers to detect if a metallic object has been placed on the pad and automatically shut off. If it doesnt, the metal would heat up to dangerous degree.

Other reports state every Qi2 transmitter will require authentication
meaning that future phones may only charge with the standard. We reached out to the WPC for clarification on device authentication as well as how Magnetic Power Profile will work and the standards other features. This story will be updated if we hear back.
