iFixit also noted that both the screen and battery are difficult to remove. The removal of the display, in particular, if not done carefully, could compromise the Touch ID technology.
"Battery and screen replacements are the two most common repairs, and the iPad Mini makes both unnecessarily difficult," iFixit said. "The battery lacks pull-to-remove adhesive tabs, and the display requires a tricky removal of the home button if you want to keep Touch ID after your repair."
