‣ iPhone 5s Repairability: 6 out of 10 (10 is easiest to repair)
‣ Just like in the iPhone 5, the display assembly is the first component out of the
phone, simplifying screen replacements.
‣ The battery is still fairly easy to access, even though it's not technically "user
replaceable."
‣ The battery has lost the 5's convenient pull tab, and gained more resilient
adhesive—it now requires heat and prying to remove.
‣ The fingerprint sensor cable could be easily ripped out of its socket if a user is
not careful while opening the phone. (iPhone 5S only)
‣ The iPhone 5s still uses Pentalobe screws on the exterior, making the 5s difficult
to open.
‣ The front glass, digitizer, and LCD are all one component, thereby increasing
cost of rep

‣ 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.
