Alongside expanding its latest changes to the Self Service Repair program to Europe, Apple today has shared a new whitepaper, “Longevity, by Design.” The paper focuses on Apple’s approach to longevity, its principles on repairability, and “the truth about parts pairing.”

“Designing the best, longest-lasting products in the world requires striking a balance between durability and repairability, while providing ongoing software updates — and we’re constantly looking for new and innovative ways to accomplish that mission,” John Ternus, Apple’s Senior Vice President of Hardware Engineering says.

The new whitepaper includes a handful of notable statistics about Apple product longevity:

• iPhone retains at least 40% more of its value compared to Android smartphones, with the valuation difference increasing for even older models of iPhone.
• There are hundreds of millions of iPhones that have been in use for more than 5 years — and that number is still growing. And Apple products remain in use longer than competitor devices.
• From 2015 to 2022, out-of-warranty repair rates were down by 38%.
• For iPhone, overall repairs for accidental damage have decreased by 44% since the introduction of improved enclosures starting with the iPhone 7 line-up.
• When liquid ingress protection was introduced with iPhone 7 and iPhone 7 Plus, repairs for liquid damage decreased 75%.
• Enabling iPhone 15 back glass repair as an individual module lowered the cost of repair for customers by over 60%.
• 85% of the US population is within a 30 minute drive of an Apple Store, Apple Authorized Service Provider (AASP) location, or Independent Repair Provider (IRP).
• 88% of third-party batteries tested in a UL Solutions study caught fire or exploded in at least one test.

Apple also highlights its “principles on repairability” in the new whitepaper:

• Principle 1: Environmental Impact
• Principle 2: Access to repair services
• Principle 3: Safety, security, and privacy
• Principle 4: Transparency in repair

Finally, the whitepaper addresses one of Apple’s controversial practices in repairability: parts pairing. Apple explains:

Parts pairing is the practice of using software to identify component parts through a unique identifier. Apple uses parts pairing to make access to repair easier and more transparent to customers while also ensuring that every device — and the data stored on it — remains secure and performs optimally. It is not to pressure consumers to go to Apple for their repairs — in fact, Apple conducts less than one third of out-of-warranty repairs. Additionally, in-warranty and out-of-warranty repair rates for Apple between 2015 and 2022 are down by 78% and 38%, respectively, reflecting increased device quality and reliability.
