Earlier this week, Apple published a whitepaper titled "Longevity by Design." The purpose, Apple says, is to explain "the company's principles for designing for longevity—a careful balance between product durability and repairability." It also contains some notable changes to Apple's parts pairing and repair technology.

Here is a summary of the action items in the document's 24 pages:

• The self-service diagnostics tool that arrived in the US last year is now available in 32 European countries.
• True Tone, the color-balancing screen feature, can soon be activated on third-party screens, "to the best performance that can be provided."
• Battery statistics, like maximum capacity and cycle count, will be available "later in 2024" for third-party batteries, with a notice that "Apple cannot verify the information presented."
• Used Apple parts, transferred from one to another, will be "as easy to use as new Apple parts" in select products "later this year."
• Parts for "most repairs" from Apple's Self Service Repair program will no longer require a device serial number to order.

Changes timed to "later this year" may well indicate their arrival with iOS 18 or a subsequent update.
