7 英寸大屏卷土重来：折叠屏与平板双重夹击，巨屏手机能否杀出「第三赛道」？

Core Viewpoint - The potential resurgence of 7-inch smartphones is being tested by two manufacturers, indicating a response to user demand for larger screens in a market filled with small tablets and foldable phones [1][4]. Group 1: Market Context - The current market already has 7-inch smartphones, such as Huawei's Mate70 Air, which measures 6.96 inches and has a width of 81.5mm, significantly wider than the Xiaomi 17 Ultra at 77.6mm, affecting user grip [1][4]. - The disappearance of large-screen smartphones in the past was attributed to usability issues, but the scarcity of large screens has diminished as technology has advanced [10][12]. Group 2: Reasons for Resurgence - The first reason for the revival of 7-inch smartphones is the increased internal space, allowing manufacturers to incorporate larger batteries, advanced imaging modules, and enhanced cooling systems [4][6]. - The second reason is the improved viewing experience, where a transition from 6.7 inches to 7 inches enhances information density, reading comfort, multitasking space, and video immersion [6][8]. Group 3: Challenges and Considerations - The main challenge for manufacturers is to ensure that the 7-inch device remains portable and user-friendly, maintaining single-handed usability and pocket storage [6][12]. - The device must provide a unique experience that differentiates it from foldable screens and small tablets, offering a straightforward large display without the need for unfolding or carrying an additional device [8][14]. Group 4: User Experience and Market Position - The 7-inch smartphone could become a "second mainstream" option for specific user groups, such as business professionals and heavy mobile gamers, rather than a universal choice [12][16]. - Manufacturers must focus on hardware weight distribution and software adaptation to fully utilize the larger screen, ensuring that it enhances user experience without compromising portability [14][18]. Group 5: Conclusion - The introduction of 7-inch smartphones represents an attempt by manufacturers to break away from market homogenization, aiming to redefine large-screen experiences without reverting to past trends [16][18].
