The Wireless Power Consortium (WPC) initially unveiled its Qi2 wireless charging standard in early 2023, with brands like Apple among its adopters. Recently, the consortium announced an upgraded specification—Qi2 25W—which elevates the charging power to 25 watts, representing a 66% efficiency boost over the original Qi2 standard that supported 15 watts.
In essence, Qi2 25W is a rebranding of the Qi2.2 specification introduced in April this year. The updated name not only provides a clearer indication of its power capacity but also makes it easier for consumers to distinguish between different product specifications.
Beyond the increased power output, Qi2 25W retains compatibility with magnetic alignment interfaces, ensuring optimal positioning for peak charging efficiency. This design also minimizes misalignment issues that could lead to charging failures, while expanding the versatility of magnetic-based use cases.
Paul Struhsaker, Executive Director of the WPC, remarked, “Qi2 25W delivers a remarkably fast and energy-efficient wireless charging experience. It will encourage broader adoption of wireless charging and accelerate the proliferation of Qi2 as a universal standard.”
Apple has already incorporated Qi2 technology into existing iPhone models and is now confirmed to adopt the Qi2 25W standard. This suggests that the upcoming iPhone 17 series, expected to debut this fall, will support the enhanced wireless charging specification. Given that recent iPhones already feature the MagSafe magnetic interface, upgrading to Qi2 25W presents no significant technical hurdles.
In contrast, the Android ecosystem has lagged slightly behind. While some devices already support Qi2, standard certification and widespread implementation of magnetic alignment remain limited. In fact, certain models still rely on auxiliary solutions—such as proprietary cases—to fully enable Qi2 functionality.
Nonetheless, WPC has revealed that hundreds of products are currently undergoing Qi2 25W certification, including numerous Android smartphones and accessories. This signals a promising future where native support for the Qi2 25W standard becomes increasingly common across the Android landscape.
