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

Very, very difficult (possibly 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 removing the rear case—this will make the most common repair, a damaged screen, nearly impossible.

Copper shielding on many components is difficult to remove and replace.

Solid external construction improves durability.
