Apple offers a built-in way to view repair details on an iPhone. This feature is called Parts and Service History, and it appears directly in the phone’s settings. Many users overlook it, but it plays an important role in safety, trust, and resale value.
This guide explains what the feature does, how it works, when to check it, and why it matters in everyday use.

What Parts and Service History Actually Shows
Parts and Service History is an official Apple feature that automatically records major hardware repairs. It works without any extra apps and updates itself whenever a supported component is replaced.
The section lists important parts such as the battery, display, cameras, and other system components. It also tells you whether those parts are genuine Apple components or something Apple cannot verify.
Apple introduced this feature with iOS 15.2. Older software versions do not support it. Most older devices, such as iPhone X and earlier models, also do not include this option.
The main goal is transparency. It helps users confirm repair claims, avoid scams, and understand what has been changed inside their phone.
Why This Feature Is Important
Knowing your phone’s repair history protects both buyers and owners.
- It confirms whether original Apple parts were used
- It warns about unknown or risky replacements
- It helps detect poor-quality repairs early
- It maintains device performance and stability
- It increases resale and trade-in value
Genuine Apple parts are designed to work smoothly with iOS. They last longer, perform better, and reduce the chance of unexpected issues.
How Parts and Service History Works
Apple uses both hardware and software checks to track repairs. Each major iPhone component has a unique identifier that pairs securely with the device’s logic board.
When a repair is done through Apple or an authorized provider, the replacement is logged in Apple’s system. iOS then checks this data against Apple’s database.
- Verified parts appear without warnings
- Unverified parts trigger alerts
- The process runs automatically in the background
For some repairs, calibration is required. This step must be completed through Apple’s systems. If calibration is skipped or incomplete, the phone may show warning messages later.
An internet connection is needed for verification. Without it, details may not load correctly.
When You Should Check Service History
You should review this section in several situations.
Before buying a used iPhone
