The iPhone 8 earns a 6 out of 10 on our repairability scale (10 is the easiest to repair):

The two most commonly replaced components, display and battery, remain straightforward to access with the proper knowledge and tools.

The addition of wireless charging means less strain on your Lightning port, a common point of failure.

Water and dust seals complicate repair, but make the need for difficult liquid damage repairs less likely.

The battery connector once again sports common Phillips/JIS fasteners—but you’ll still need up to four different driver types for many repairs.

The durability of the glass back remains to be seen—but replacements are likely to be very difficult.

The iPhone’s lower components, once readily removed, now lie trapped under a fussy combination of brackets and delicately folded flex cables.
