iFixit于2024年10月26日完成了对苹果折叠屏手机iPhone Duo的拆解 1。该机型获得了5分（满分10分）的可维修性评分，创下iFixit折叠智能手机历史最高分 1。在硬件规格方面，这款设备具备IP68防尘防水等级，能在6米深水下浸泡30分钟 1。
此次拆解重点是铰链设计，并初步锁定了用户反馈的屏幕早期故障潜在诱因 1。绝大多数屏幕故障集中在两半机身连接线的开孔与铰链中部支撑结构的衔接区域 1。故障推测为支撑条无法正常收回从而持续向内挤压屏幕，或弧形导轨卡滞剐蹭屏幕 1。
在内部构造上，iPhone Duo采用了双电芯设计，大电池容量为11.567瓦时，小电池容量为7.506瓦时，合计19.073瓦时 1。此外，该机型采用电控可释放胶，不用强行撬取电池 1。
iFixit has completed a teardown of the Apple iPhone Duo, assigning the foldable smartphone a repairability score of 5 out of 10, which marks the highest rating ever recorded by the organization for a folding phone 1. The device features an IP68 dust and water resistance rating, capable of withstanding immersion at depths of up to 6 meters for 30 minutes 1. Power is supplied by a dual-cell battery configuration comprising a larger cell rated at 11.567 Wh and a smaller one at 7.506 Wh, totaling 19.073 Wh capacity 1. To facilitate safe removal during repairs, the batteries are secured with electrically releasable adhesive rather than requiring forced prying 1.
The analysis focused heavily on the hinge mechanism to address user-reported issues regarding early screen failures 1. Most display defects appear to originate in the interface area between the opening for the connecting cable—located between the two halves of the chassis—and the central support structure of the hinge 1. iFixit suggests that these malfunctions may be caused by either the support bar failing to retract properly, leading it to continuously press inward against the screen, or by sticking within the arc-shaped rails that results in abrasion to the display surface 1.
