Core Viewpoint - The newly launched iPhone Air, which is the thinnest iPhone to date, has seen significant price reductions shortly after its release, indicating poor market performance and a need for inventory clearance [1][3]. Group 1: Product Performance - iPhone Air was launched on October 22, 2025, but has underperformed in the market, with cumulative activation numbers below 200,000 units by January 24, 2026, which is only about one-third of Apple's highest expectations [2]. - The device's thickness is only 5.6 mm and weighs 165 grams, making it the thinnest iPhone ever, but compromises were made in battery capacity and camera features to achieve this design [2]. - The resale value of iPhone Air has dropped significantly from over 6,000 yuan to around 4,000 yuan, reflecting its poor market reception [1]. Group 2: Pricing and Promotions - Apple has initiated multiple promotional activities for iPhone Air, including a recent price cut of 2,000 yuan from the original price of 7,999 yuan, bringing the effective price down to 5,499 yuan [1][3]. - The stock available for the promotional event was only 13,000 units, indicating limited inventory [2]. Group 3: Market Challenges - The use of eSIM technology in iPhone Air has posed challenges, as the process for activating eSIM is cumbersome compared to traditional SIM cards, which may deter potential buyers [4]. - The mismatch between innovative technology and local consumer habits has led to difficulties in market acceptance, highlighting the need for better adaptation to local infrastructure and consumer preferences [4][5].

Core Viewpoint - Apple's introduction of VC (Vapor Chamber) cooling technology in the iPhone 17 Pro series marks a strategic move towards localized AI computing and enhanced mobile performance, responding to the growing demand for AI smartphones and AR glasses [1][2]. Supplier Dynamics - **Bowen Alloy**: The company confirmed that its VC cooling materials have become a core component in a leading A company's high-end models and will be fully applied in the upcoming AI smartphone. This indicates a continuous increase in the market share of domestic suppliers within the Apple supply chain [3][5]. - **Rongqi Technology**: As a core supplier of wireless charging module testing equipment, the company has reached mass production of VC material and module testing equipment, enhancing quality control and testing processes in the VC industry [6][8]. VC Technology Overview - VC, or Vapor Chamber, is an advanced thermal management technology that outperforms traditional heat pipes, especially in managing heat in high-density electronic devices. It offers higher thermal conductivity and can quickly distribute heat across a larger area [9][10]. - The structure of a VC consists of two copper plates with a capillary structure in between, utilizing phase change principles to manage heat effectively. This technology is evolving from 1D heat pipes to 2D VC and even 3D VC solutions, which provide better thermal management for high-power devices [12]. VC Supply Chain - The VC technology has become a critical path for thermal upgrades in smartphones, with domestic companies gradually filling in the gaps in the supply chain, providing comprehensive support for thermal management in the Apple ecosystem. The demand for VC cooling solutions is expected to grow with the increase in AI terminals and wearable devices [17]. Upcoming Events - The 6th Thermal Management Industry Conference and Expo (iTherM2025) will take place from December 3-5, 2025, at the Shenzhen International Convention and Exhibition Center, showcasing various companies involved in VC materials, equipment, and modules [19].
