It’s ironic, but we were here at WIRED Fans of wireless charging processes. Not having to fumble with cables is nice! Most wireless chargers follow the Qi (pronounced Chee) Standard that took his time to be omnipresent. ((The user experience was not always great..
Unfortunately, Qi2 did not spread as quickly or widely as we expected. While each iPhone (from 12 series one) Qi2 now supports, only a Qi2-certified Android phone was published in 2024. The HMD skylineAnd we were dismayed when we found that it did not work with some older Qi charging devices. Hopes that a different story could be in 2025 have an early knock on the news that Samsung Galaxy S25 is only ready Qi2. So what’s wrong with Qi2?
Updated in February 2025: We have added further details on the Qi2 adoption and an explanation of the new Qi2 completed cases and phones such as Samsung Galaxy S25.
What is Qi2?

Qi2 is an open wireless charging standard from the Wireless Power Consortium (WPC), and it brings important upgrades over the original Qi standard. The heading is the Magnetic performance profile (MPP)What is based on Apple Magsafe technology. (Apple was involved in the development of the Qi2 standard.) This enables Qi2 brand devices to add magneticering to ensure perfect focus on chargers and enable faster charging speeds.
There is another standard: the non -magnetic wireless charge Extended performance profile (EPP). According to Paul Golden from WPC, EPP refers to a device that corresponds to the specification, but is not officially Qi2 and therefore cannot be used or the logo cannot be referred to as a Qi2 device. Golden said in an e -e -mail that such devices would “carry the Qi logo, not the Qi2, and packaging and/or marketing materials have a necessary statement that the device does not contain any magnets. Each device with Qi2 is MPP and must contain magnets. “
In order to continue to muddy, we now have the “Qi2 ready” Samsung Galaxy S25 series. The Galaxy S25, S25+and S25 Ultra support the Qi charge standard from the box and you have no magnets. However, you can add magnets by buying your own Qi2 already cases (available from Samsung and third). Combine a certified and tested Qi2 -Ready case with a Qi2 -Ready phone, and you have a Qi2 effectively Qi2 Power Banks and chargers.
This frustrating and somewhat confusing stop gap is probably due to the long development cycle of telephones and the difficulty to design magnets into them. Look on the bright side because Qi2 is ready, cheaper and easier, it can be a practical way to bring Qi2 cheaper telephones.
