To be among the first ones to get the new iPhone, the iFixit team went all the way to Australia. Though the exterior of the device reveals nothing special (ok, aside from the dual-LED and new Home button containing the Touch ID) when compared to the older model, it is known what ultimately matters the most ? what is inside.
Just as the outside appearance of the iPhone 5s suggests, disassembly is very similar to the predecessor. However, iFixit points out that one must be very careful with the separation of the screen part, because it is connected via cable to the Touch ID sensor. It is recommended to pop the screen out with utmost care so the cable doesn?t rip apart. iFixit also experienced some concern over the durability of the sensor:
"We worry about how well the sapphire crystal covering the sensor can protect it from degrading over time like most CMOS fingerprint sensors. If not, it could become a ticking time bomb, just like that super-glued battery."
Battery found in the new unit is a 1560mAh, an improvement from the previous 1440mAh. iFixit also revealed that the unit likely has 1GB of RAM, but they were unable to find the M7 coprocessor/chip that is supposed to continuously measure motion data and control sensors. Apple gave the impression that it is a separate component inside the new iPhone, but as it turns out to be the case, it is likely hidden within the A7 itself ? or it is merely a combination of motion-oriented components according to the iFixit. Disassembly also revealed why the new iPhone doesn?t support the newer Wi-Fi standard (802.11ac) – Murata Wi-Fi module based on the Broadcom BCM4334 is at blame here.
Reparability score of the new iPhone is 6/10, and you can find the video and photos of the process below:
Update: The guys at Chipworks have unearthed the mythical M7 processor, made by none other than NXP.
