iPhone Duo is undoubtedly one of the most technologically interesting products that Apple introduced in recent years. However, its construction is also significantly more complex than that of classic iPhones and now it turns out that it is also giving its manufacturers a real challenge. According to information from the Chinese server Jiemian News, the final assembly yield reached iPhone Duo at Foxconn as of September 17, just over 60%. In other words, almost four out of ten units produced at this stage will not meet the requirements needed to continue without further intervention. 

It's not necessarily that almost 40% of iPhones Duo rolled off the production line completely non-functional and headed straight for the trash. Production yield expresses the proportion of pieces that meet the required parameters at a given production step. The rest may require further adjustments, inspection or rework. However, even a “mere” repair is ultimately for Apple a problem because it will delay production and therefore logically affect inventory. 

Apple He doesn't want to back down from his demands yet.

The problems are mainly due to the combination of a very complex design and strict requirements. Apple quality. According to sources, Foxconn is repeatedly adjusting production equipment, procedures, and various assembly parameters so that it can get a larger number of phones through inspection. Suppliers are reportedly even waiting to see if Apple will not ease some of its demands and thereby facilitate increased production. However, there is no indication yet that it is preparing to do anything similar. 

Moreover, the complications are not only caused by final assembly. Foldable OLED panels from Samsung Display are also said to suffer from poorer yields, and the problems are also said to affect some components.oneThe hinge is one of the most important parts of the entire phone and Apple It uses a design consisting of more than a hundred components. The delay of some componentsoneThis also reduces the time Foxconn can devote to tuning the production lines themselves. 

According to one of the sources of Jiemian News, while maintaining current standards, it can AppIt will take another six months to a year for production to reach standard yield levels. Of course, this does not mean that it should iPhone Duo reach customers in a problematic state. Pro Apple However, the current situation may primarily mean lower initial stocks. Pro According to Jiemian News, around 6 to 8 million units are expected to be produced in 2026. Hopefully, some of these test pieces will reach our editorial office soon, so we can see for ourselves whether these phones are really worth it.
