This is irony, but we are a long fan in Wired here wireless chargingIt is good not to have a fambal with cable! These days most wireless charging devices follow the Qi (pronunciation Chi) standard, which has delivered its time to omnipresent. ,User experience has not always been great.) Wireless Power Consortium, which manages the charging protocol, announced the next generation version called QI2 in early 2023, and we are eventually beginning to see the equipment supporting. This promises the correct alignment, which is likely to have goods to bridge Android and iPhone divide.
It is a matter of regret that QI2 has not come out as quick or widely as this year. By August 2024, only one QI2-certified android phone is, HMD horizon (6/10, wired review), And we were disappointed to know that it did not work with some old Qi Chargers. Is QI2 Unstaccating?
Updated on August 2024: We added details on QI2 adoption, explanation on various certification options, and unwanted news that some QI2 devices cannot charge with QI Chargers.
What is Qi2?

Qi2 new open wireless charging is standard Wireless power consortium (WPC), and it brings significant upgrades to the original Qi standard. The headline is a magnetic power profile (MPP), which is based on Apple Magsef technology(Apple QI2 was involved in developing standard.) This allows the QI2-branded devices to ensure the correct alignment with the chargers and allow a ring of magnets to allow for rapid charging speed.
Another standard is, nonamagnetic wireless charging extended power profile (EPP). This caused Some confusionAccording to Paul Golden of WPC, Epp refers to a device that complies with specification, but it is officially QI2 and thus cannot use logo or can be referred to as QI2 devices. . Golden told Wired in an email that such devices would “take the QE people, not QE2, and a required statement in the packaging and/or marketing materials that the device does not have magnets. Any device of QI2 is MPP And it should include magnets.
QI2 is also fully backward compatible, so you can charge an old Qi Android phone or Magsafe iPhone on the QI2 charger. We have done many tests, and this is true. We expected any old Qi Chargers to charge the QE2 devices, which is slow, but it turns out that it is not true. For example, HMD Skyline, we did not work with many old QE Chargers, which we tested, and it seems that it could be equal to the course. We have to wait for more QI2 phones to find out this, but failed to adopt QI2 in their latest flagship with heavyweight like Google and Samsung.
