Apple reused binned chips across iPad, iPhone 4, and MacBook Neo

Apple used chip binning to reuse chips that failed quality control in other products, and a 9to5Mac report published on May 18, 2026 said the practice dates back to the original iPad and iPhone 4.

Chip binning is a manufacturing process in which a company classifies chips by performance or defects after production and assigns them to different products or configurations. According to the 9to5Mac report, Apple has used this process for years to repurpose chips that did not meet the target specification for an original device.

The 9to5Mac report said Apple reused chips not only within different versions of the same product line but also across entirely different products. The report said this approach dates back to the original iPad and iPhone 4, adding historical examples to more recent discussion around the MacBook Neo.

The source excerpt did not provide technical specifications, chip model numbers, or quantities for the affected devices. The source excerpt also did not state whether Apple publicly commented on the reported examples of chip reuse.
