It is ironic, however we right here at WIRED have lengthy been wi-fi charging followers. Not having to fumble with cables is sweet! Most wi-fi charging gadgets today observe the Qi (pronounced chee) normal, which has taken its time reaching ubiquity. (The consumer expertise has not at all times been nice.) The Wi-fi Energy Consortium, which manages the charging protocol, introduced the next-generation model referred to as Qi2 in early 2023. Qi2 wi-fi charging guarantees excellent alignment, with the potential for equipment to bridge the Android and iPhone divide.
Sadly, Qi2 has not rolled out as shortly or broadly as we anticipated. Whereas each iPhone (from the 12 collection on) helps Qi2 now, there was just one Qi2-certified Android telephone launched in 2024, the HMD Skyline, and we have been dismayed to seek out that it didn’t work with some older Qi chargers. Hopes that 2025 is likely to be a unique story have taken an early knock with the information that Samsung’s Galaxy S25 is just Qi2 Prepared. So, what is going on on with Qi2?
Up to date February 2025: We added extra particulars on Qi2 adoption and an evidence of the brand new Qi2 Prepared instances and telephones like Samsung’s Galaxy S25.
What Is Qi2?

Qi2 is an open wi-fi charging normal from the Wi-fi Energy Consortium (WPC), and it brings essential upgrades over the unique Qi normal. The headline is the Magnetic Energy Profile (MPP), which relies on Apple’s MagSafe know-how. (Apple was concerned in creating the Qi2 normal.) This permits Qi2-branded gadgets so as to add a hoop of magnets to make sure excellent alignment with chargers and permit for quicker charging speeds.
There’s one other normal: the nonmagnetic wi-fi charging Prolonged Energy Profile (EPP). Per WPC’s Paul Golden, EPP refers to a tool that complies with the specification, however is just not formally Qi2 and thus can not use the emblem or be known as a Qi2 machine. Golden advised WIRED in an e-mail that such gadgets “would carry the Qi brand, not Qi2, and packaging and/or advertising supplies have a required assertion that the machine doesn’t include magnets. Any machine labeled Qi2 is MPP and should embrace magnets.”
To muddy the waters additional, we now have the “Qi2 Prepared” Samsung Galaxy S25 collection. Out of the field, the Galaxy S25, S25+, and S25 Extremely help the Qi wi-fi charging normal, and they don’t have magnets. However you’ll be able to add magnets by shopping for your personal Qi2 Prepared instances (out there from Samsung and third events). Mix a licensed and examined Qi2 Prepared case with a Qi2 Prepared telephone and also you successfully have a Qi2 telephone (with the identical enhanced charging velocity and effectivity) that you need to use with Qi2 energy banks and chargers.
This irritating and considerably complicated stopgap is probably going as a result of lengthy improvement cycle of telephones and the problem of designing magnets into them. Trying on the intense facet, since Qi2 Prepared is cheaper and simpler, it might be a viable path in bringing Qi2 to cheaper telephones.
