"Teardowns and Analysis Unveil Mixed Bag of Design Decisions and Repairability for iPhone 15 Series"

A teardown of the iPhone 15 by iFixit reveals that while it can be opened from both the back and front, similar to the iPhone 14, the components now sit behind the screen instead of the back glass. This design decision makes battery replacements riskier as the screen needs to be removed. The iPhone 15 also features USB-C charging and a titanium shell, which iFixit questions due to its difficulty to work with and limited recycling options. The device's repairability is hindered by Apple's parts pairing policy, leading iFixit to give the iPhone 15 a repairability score of 4/10.
