Nexus 5 Repairability Score: 8 out of 10 (10 is easiest to repair).

Very modular design allows independent replacement of several wear-prone components—like the headphone jack and speakers.

Only very mild adhesive holds the battery in place, making it fairly easy to safely remove and replace.

Standardized screws (ten identical #00 Phillips) simplify repairs and reassembly.

The back cover is held in place with plastic clips. Sturdy and rather difficult to remove, but easier than glue.

The glass and LCD are fused to the display frame. Fixing broken glass will be either expensive or very difficult.
