Well, the answer is true to some extent. It has been always shown that repairing iPhones from third-party companies is becoming impossible because it is really becoming a very challenging task to repair every individual component. Steps of Repairing of iPhones is pretty problematic as it involves changing processors and therefore pairing one component to another in an unnecessary manner. The right to repair scheme is definitely helpful for the consumers in order to have their products repaired while maintaining a decent price range which basically means that the consumer has the power to repair it from any third-party service rather than the manufacturers.
However, it seems like Apple doesn't want to provide this facility to their customers regarding repairing their products such as phones and MacBooks from any third-party companies. It is basically because it slows down the sales of their service centre and therefore their employees are suffering as they are becoming unable to charge a high price for repairing their products. However, they have also been accused of badly in the process of making iPhones slower with the old batteries.
Using their service centers, will definitely increase the company sales and therefore extends the potential market. In the defense of the accused, Apple replied that the lower quality parts are basically used by third-party companies which makes their devices vulnerable. Along with that, they have also defended that their warning battery low signal is nothing but an indication that can therefore be considered as a safety feature. The Repairing Program of Apple has been in buzz for the sake of accessing the requests by third parties in the US. However, the scheme is not available outside the US.
The new launch iPhone 13 - Apple made it impossible for any third-party organizers to repair those in order to increase their own sales revenue and therefore make people rely only on their own customer services. They have increased the repair charges to more than 30% for all iPhones.
