"Then we have the Nexus 4 which got the same score (6) as the 5S but doesn't have things like glue holding the battery in place and a taking it apart requires "minimum effort":" Did you read the Nexus tear down or just look at the score? From the tear down: The battery is stuck to the frame with a lot of adhesive, so removing it without puncturing the battery can be difficult. The glass is fused to both the display and the display frame. So don't crack the glass unless you're good with a heat gun, or you're fond of replacing the glass, display, and frame together ($$$).
