Apple says iPhones will better support third-party displays and batteries later this year

Apple today released a lengthy white paper that 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 would work with third-party iPhone displays later this year:

True Tone requires precise calibration to work properly, and it is not possible to engage a default calibration for third-party displays, which may result in unexpected behavior. 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 provide more comprehensive support for third-party parts, starting in late 2024, Apple will allow consumers to enable True Tone with third-party parts to achieve the best performance that can be delivered.

They will be able to disable True Tone in the settings if the screen does not work to their satisfaction.

True Tone automatically adapts the screen color based on the light in your environment.

Second, Apple said that battery health indicators, such as maximum capacity and number of cycles, would work with third-party iPhone batteries later this year:

Currently, battery health metrics such as maximum capacity and number of cycles are not shown to consumers whose devices are equipped with third-party batteries. Indeed, the accuracy of these measurements cannot be verified by Apple. In fact, an internal Apple analysis found that some third-party batteries sold as new are actually used, with battery health metrics manipulated to appear new. In an effort to improve support for third-party batteries, starting in late 2024, Apple will display battery health metrics with a notification that Apple cannot verify the information presented.

Apple has stated that third-party battery measurements are not guaranteed to be accurate.

These changes will likely roll out with iOS 18 updates later this year, but Apple didn’t provide a more specific timeline in its document.
