HTC One M8 Repairability Score: 2 out of 10 (10 is easiest to repair)

It's very difficult—although no longer impossible—to open the device without damaging the rear case. This makes every component extremely difficult to replace.

The battery is buried beneath the motherboard and adhered to the midframe, hindering its replacement.

The display assembly cannot be replaced without tunneling through the entire phone. This makes one of most common repairs, a damaged screen, very difficult to accomplish.

Copious amounts of tape, adhesive, and copper shielding make many components difficult to remove and replace.

Solid external construction improves durability.
