iPhones will Support Third-Party Displays and Batteries

 Apple will Support Third-Party Displays and Batteries on iPhones in the near future 

Apple will add support for third-party displays and batteries on its iPhones by the end of 2024. Apple published a white paper, “Longevity, by Design '' which explains the company's principles to improve the longevity of devices.  Apple published a lengthy whitepaper which highlights the company's approach to device repairability and longevity. In the document, Apple revealed that iPhones will better support third-party displays and batteries later in 2024. First, Apple said True Tone will work with third-party iPhone displays later this year:

In the white paper, the company says that they will allow consumers to activate True Tone on the iPhones with third-party displays. "In an effort to offer more complete support for third-party parts, starting later in 2024, Apple will allow consumers to activate True Tone with third-party parts to the best performance that can be provided," the white paper read. True Tone requires precise calibration to function properly, and it is not possible to engage a default calibration for third-party displays, which can result in unexpected behaviour. For this reason, Apple disables the True Tone feature when third-party displays are used, but enables all other aspects of the display. In an effort to offer more complete support for third-party parts, starting later in 2024, Apple will allow consumers to activate True Tone with third-party parts to the best performance which can be provided. They will be able to deactivate True Tone in Settings if the display does not perform to their satisfaction. True Tone automatically adapts the colour of the display to match the light in your environment.

In terms of battery, Apple says iPhones with third-party batteries will show battery health metrics. "Currently, battery health metrics such as maximum capacity and cycle count are not presented to consumers whose devices have third-party batteries. This is because the accuracy of these metrics cannot be verified by Apple. In fact, an Apple internal analysis has found that some third-party batteries sold as new are actually second hand, with battery health metrics manipulated to appear as new," read the white paper.

Apple said the third-party battery metrics are not guaranteed to be accurate.

"In an effort to improve support for third-party batteries, starting later in 2024, Apple will display battery health metrics with a notification stating that Apple cannot verify the information presented. When selecting a third-party battery for repair, we encourage all consumers to confirm that the product meets stringent safety requirements," it further added. It also further said that the consumers can deactivate True Tone in Settings if the display does not perform to their satisfaction. These changes will presumably be rolled out with iOS 18 updates later this year, but Apple did not provide more specific timing in its document about it's availability.
