Apple iPhone 16: Revolutionary Adhesive Technology Boosts Repairability and Sustainability
Apple’s Latest iPhones Reveal Innovative Battery Adhesive Technology
As iFixit begins its traditional teardown of the newly released iPhone 16 lineup, tech enthusiasts are getting their first glimpse into the device’s internal architecture. Notably, Apple’s decision to provide day-one release of repair manuals has significantly streamlined the disassembly process.
Initial observations from the teardown have highlighted several key features, including a physical button for camera control, a flex cable for force measurement, and a heat sink specifically designed for the A18 chip’s Neural Engine.
However, the most groundbreaking discovery lies within the base iPhone 16 model’s battery enclosure. Apple has implemented an electrically debondable adhesive, a technology first reported by The Information in June. While this innovative adhesive is not yet present in all iPhone models, it marks a significant step forward in repairability.
Apple’s repair documents detail the adhesive process, which aligns with Tesa’s debonding-on-demand demonstration. The procedure involves disconnecting the battery from the board, applying an electric current (such as a 9-volt battery) for 90 seconds, after which the battery can be easily detached, often by gravity alone. Reattachment is equally straightforward, requiring only pressure application to the new battery.
iFixit’s investigation revealed that a 20V current can undo the bond in as little as five seconds, with Apple allowing currents up to 30V. The team also noted that the release time for the adhesive may increase over time.
Microscopic examination of the frame revealed machined ridges, which appear to enhance battery adhesion. This attention to detail underscores Apple’s commitment to both innovation and practicality in their device design.
As the tech community continues to explore the intricacies of the iPhone 16 lineup, this new adhesive technology stands out as a potential game-changer in smartphone repairability and sustainability.
