Three years ago Apple announced a free repair program for a “defect” in an iPhone. The company has now ended the program as it is not mentioned on the website. the iPhone is in question iPhone 8 and the problem was with the logic board of the smartphone. According to a Macrumors report, Apple will now not repair the iPhone 8 “for free” if it had this particular defect.
As early as August 2018, Apple had determined that “a very small percentage of iPhone 8 devices contain logic boards with a manufacturing defect.” The defect had resulted in users experiencing a frozen screen, unexpected restarts, or some devices not turning on. Apple had announced that it would repair the defective device free of charge. It applied to units sold between September 2017 and March 2018 in Australia, China, Hong Kong, India, Japan, Macau, New Zealand and the United States.
The iPhone 8 is now a four year old iPhone and chances are very few people have this problem, or even if they let Apple fix it for free.
Apple routinely runs such replacement or repair programs. There are now programs for iPhone 12 and iPhone 12 Pro that have certain sound problems. The iPhone 11 also has a display replacement program, while the AirPods Pro also has a replacement program.
Note that these programs are only designed for specific errors and do not apply to all models. In general, this only applies to devices that were sold within a certain period of time. Like the iPhone 8 program, it only applied to devices sold between September 2017 and March 2018. It is also not valid worldwide and only for certain countries.
