Those who use new, non-original batteries to repair their devices will not be penalized.
Whether they like it or not, companies are forced to do something so that users can fix their broken devices at home. Although aftermarket third-party components have been around for a long time, when used, iOS devices can send notifications or take them out entirely.
Currently, Apple only supports unused, original Apple-produced items, which must be ordered with the serial number of the repaired device. However, in the fall, the company becomes more lenient, as the serial number will no longer be required, and the system will accept new and used items as long as they are original.
However, in the first round, only displays, batteries and cameras will be usable, and in the case of the Face ID and Touch ID sensors, new hardware will have to be installed. iOS will also be able to detect if the parts used are from a stolen device and does not allow for a full calibration.
It's not clear at the moment what devices the discount covers, but it may also include the iPhone 15 and later.
The use of aftermarket components is still not supported.
