Core Viewpoint - The wireless charging technology, despite being around for nearly 15 years, has not seen widespread adoption compared to other smartphone features, with the Wireless Power Consortium (WPC) asserting that the technology is not at fault [2][3]. Group 1: Qi2 Protocol Updates - WPC recently updated the Qi2 protocol to version 2.2.1, increasing the charging power from 15W to 25W, a nearly 70% increase [3][6]. - The updated protocol aims to expand its ecosystem to include mainstream Android smartphones, although the first compliant devices do not support magnetic alignment [6][12]. - The Qi2 protocol emphasizes the magnetic alignment feature, which is considered essential for faster and more efficient wireless charging [6][12]. Group 2: Market Adoption Challenges - Despite the introduction of the Qi2 protocol, the actual adoption of magnetic charging technology in smartphones has been limited, with only a few models, such as Nubia Z40 Pro and HMD Skyline, fully supporting it [13][14]. - The slow adoption is attributed to the fact that many manufacturers prefer their proprietary high-power charging protocols over the Qi2 standard, which is seen as lagging behind [16][19]. - The requirement for built-in magnets in devices complicates design and manufacturing, as current smartphone designs prioritize battery and camera size over compatibility with Qi2 [17][20]. Group 3: Competitive Landscape - The competitive landscape is further complicated by the existence of a mature market for third-party magnetic accessories, which has developed independently of the Qi2 protocol [22]. - Major players like Apple have successfully integrated magnetic charging into their ecosystem, while competitors like Samsung have faced challenges due to design constraints and interference issues with existing features [23][24]. - The future of Qi2 adoption remains uncertain, as manufacturers continue to prioritize proprietary solutions in a market characterized by increasing component density and competition [25].
