Core Viewpoint - The new iPhone 17 has different MagSafe charging power between the Chinese and international versions, with the Chinese version limited to 15W while the international version supports 25W due to compliance with the Qi2 25W standard [1][3][26]. Group 1: Charging Standards and Technology - The Wireless Power Consortium (WPC) released a new wireless charging standard, Qi2.2, in April, which supports a maximum power of 25W [8]. - The Qi2.2 standard includes two upgraded protocols: Magnetic Power Profile (MPP) for magnetic alignment and Active Alignment Profile (APP) for vehicle charging scenarios, enhancing the power output from 15W to 25W [19][20]. - The Qi2.2 standard has undergone rigorous testing, with a prototype achieving an input power of 24.22W while maintaining a maximum temperature of 37.6 degrees Celsius during charging [23]. Group 2: Market Implications and Manufacturer Responses - Domestic manufacturers are advancing wireless charging technology to nearly 100W, while international counterparts are still focused on 25W, highlighting a disparity in market focus [13]. - The lack of support for the Qi2.2 standard in China is attributed to regulatory issues, as the new standard operates at a frequency of 360kHz, which does not comply with recent regulations from the Ministry of Industry and Information Technology [25][26]. - Manufacturers like OPPO are hesitant to integrate magnetic components into their devices, opting instead for solutions that require compatible magnetic cases, which complicates the user experience [32][34]. Group 3: Future of Wireless Charging - The establishment of a universal wireless charging standard is deemed beneficial for user experience and industry health, despite current regulatory and design challenges [36][37]. - The industry is encouraged to pursue a common wireless fast charging protocol to enhance compatibility across brands, which would ultimately benefit consumers [36].
