HTC One M9 Repairability Score: 2 out of 10 (10 is easiest to repair)

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.

Intense adhesives make many components difficult, and even dangerous, to remove and replace.

HTC thought they could Have Their Cake and eat it too, by making a flagship phone that's tough to repair. Sorry HTC, but this design Has To Change.

Design streamlining (upper access panel and reduced tape/shielding) makes for slightly easier access to some components.
