It is sarcastic, but we are here at Wired for a long time. Wireless charger. It is not good to grow with the cable! Most of today's wireless charging devices according to QI standards (pronunciation is Chee), it takes time to reach the popularity. .The user experience is not always great.)) The Wireless Energy Association, where the charging protocol management, has announced the next generation version called QI2 in early 2023 and finally started to see devices that support it. It promises a perfect link, with the potential for accessories to connect to Android and iPhone division.
Sadly, Qi2 did not launch as quickly or spacious as we expected this year. As of August 2024, only one Android phone was certified QI2, HMD horizon (6/10, wired evaluation), and we were unwell when we saw that it didn't work with some old QI chargers. QI2 is not coming?
Update August 2024: We have added details about the application of QI2, clarifying different certification options and unwanted news that some QI2 devices cannot charge with the QI charger.

QI2 is a new wireless charging standard from CONTACT Wireless Energy (WPC), and it offers important upgrades compared to the original Qi standard. The title is the magnetic energy configuration (MPP), based on Apple Magsafe technology. .
There is another standard, wireless expansion energy records are not calculated (EPP). This has led to Some mistakes. According to WPC's Paul Golden, EPP refers to a device that complies with specifications, but it is not informal QI2 and therefore cannot use the logo or is called the QI2 device. Golden told Wired in an email that such devices will bring the QI logo, not QI2, and packaging documents and/or marketing have a mandatory statement that the device does not contain magnets. Any device labeled QI2 is MPP and must include magnets.
QI2 is also fully compatible, so you can charge the older Android QI or iPhone Magsafe on the QI2 charger. We tested some, and this seems right. We also expect any old QI charger to charge the QI2 devices, although at a slower speed, it turns out that it is not right. For example, HMD's horizon was not working with some old QI chargers that we tested, and it seems that this could be equal to the course. We will have to wait for more QI2 phones to find out, but for heavy rivals like Google and Samsung did not apply QI2 in their latest flagships, it could be a moment.
