- Oppo’s Find N6: Boasts an 8.12-inch inner display and a 6.62-inch outer display. It’s notably thin at about 8.93mm when folded and weighs around 225 grams.
- Vivo X Fold6: Offers an 8.02-inch inner display and a 6.51-inch outer display, with a starting weight of approximately 228 grams.
In contrast, Apple’s inaugural iPhone Duo, while showcasing impressive engineering, weighs around 254 grams and measures 11.3mm thick when folded. This places it on the heavier and thicker side compared to the latest generation of flagship Chinese foldable phones. This comparative analysis underscores a critical point: while Apple is just beginning to define what a foldable iPhone should be, Chinese manufacturers have already moved the goalposts, focusing on making foldables as thin and light as conventional flagship smartphones, pushing towards a future where the folding mechanism doesn’t inherently compromise portability.
Nonetheless, weight and thickness are not the sole determinants of user experience. Apple brings its renowned expertise in structural design, materials science, and display technology. The company’s claims of a significantly reduced crease and the industry’s thinnest unfolded profile indicate a strong focus on premium feel and visual integrity. However, in terms of sheer hardware iteration and experience with the complex mechanics of foldable devices, Chinese manufacturers demonstrably hold a lead.
Beyond the Hinge: The Software Battleground
While hardware innovation is crucial, the ultimate success of foldable phones hinges on software optimization and how genuinely useful the larger screen can be. Early generations of foldables often struggled with software that merely stretched existing smartphone interfaces, failing to leverage the expanded display real estate effectively.
Apple’s iPhone Duo tackles this by introducing robust split-screen multitasking capabilities and full Apple Pencil support. This approach aims to transform the unfolded device into a legitimate productivity tool, enabling users to manage multiple applications concurrently, sketch ideas, or take notes with precision. The emphasis is on enabling users to "handle multiple tasks" rather than just view an "enlarged version of the standard iPhone interface."
Chinese manufacturers have been pursuing similar, if not more aggressive, software strategies. The Vivo X Fold6, with its 8.02-inch inner display, already offers sophisticated multitasking features. Oppo’s Find N6 positions itself as a "Pocket AI Workstation," featuring multiple apps running simultaneously, resizable windows, and desktop-style multitasking functionalities like Split View. Huawei’s Mate XT 2, a tri-fold design, goes even further by integrating advanced AI features such as split-screen translation, AI call summaries, AI call translation, and multi-device collaboration.
