Inside we find an army of courageous tri-point screws guarding the cable bracket that covers the battery connector and two of the display cables.

A year ago we went out on a limb and added the Apple watch screw to our 64-bit toolkit. Boy, what a good thing we did.

A second platoon of tri-points secure the bracket for the long and springy upper component display cable.

Tri-point screws are uncommon. While you could make the argument that tri-point screws are less likely to strip, we assume if it was a choice of mechanical advantage, we'd see them throughout iDevices. It's pretty clear that they are here to simply hinder the two most common user repairs: battery and screen replacements.

We dispatch our own weaponry screwdriver and force the bracket to surrender so we can continue our mission into the heart of the iPhone 7 Plus.
