iPhone 5 Torn Down: Easier To Fix Than iPhone 4S
The folks at iFixIt did what they do best and promptly gutted the iPhone 5 in their latest tech autopsy. They've been doing this type of thing for some time now, grading devices with a Repairability Score that ranges from 1 to 10; the higher the score, the easier it is to crack open a device and service it at home.

So, how'd the iPhone 5 do? In typical Apple fashion, the iPhone 5 is sealed shut with funky Pentalobe screws on the exterior, which means your standard Phillips or Flathead screwdriver isn't going to do the trick. iFixIt also noted that the front glass, digitizer, and LCD are all one component, so if one breaks, you're looking at a more costly repair than if they were all separate. Rounding out the negatives is existence of several smaller components being soldered to one ribbon cable. Boo!
On the unusually bright side, the iPhone 5 is, overall, actually easier to service than the iPhone 4S, scoring a 7/10 versus a 6/10. That's not too shabby.

"We're quite happy that the glass/display is the first thing that comes off the iPhone 5," iFixIt explains. "The majority of iPhone repairs are due to a shattered front glass."
The tech surgeons were also impressed that the battery comes out relatively easily with just a bit of prying once the front panel is removed.
