Qi2 (correctly Qi v2.0 MPP, for Magnetic Energy Profile) is a brand new magnetic wireless charging standard that may cost suitable units at as much as 15W. Like Apple’s MagSafe, it makes use of rings of magnets in each system and charger to make sure correct alignment of the charging coils, and it’s based mostly on the Qi wi-fi charging customary that’s utilized by almost each system that gives wi-fi charging. Actually, Apple contributed the magnetic power profile technology to the brand new customary.

In contrast to MagSafe, Qi2 isn’t proprietary. It’s administered by the Wi-fi Energy Consortium, and though units must be Qi2-certified, they don’t require particular Apple {hardware} or MFi certification, which implies they’re inexpensive to supply. As of iOS 17.2, the iPhone 13, 14, and 15 are Qi2-certified and may cost simply as quick from a Qi2 charger as they will from a MagSafe-certified charger; on all different wi-fi chargers, iPhones are restricted to 7.5W most.

As a result of Qi2 is an open customary, it may be built-in into Android telephones and different units, although it hasn’t been but. And attributable to backward compatibility quirks, Android telephones that may hit 10W or extra on a regular Qi charger (or a “MagSafe-compatible” Qi charger with magnets) are restricted to only 5W on Qi2. Within the close to future, households with Android and iPhones ought to have the ability to share the identical magnetic chargers and equipment and get the identical cost charges. For now, although, Qi2 is greatest fitted to iPhones.
