IFIXIT'S IPHONE DUO TEARDOWN GIVES THE BEST FOLDABLE REPAIR SCORE SO FAR, BUT THE INNER SCREEN IS THE CATCH

Summary from the TLDR Hardware newsletter

iFixit gives the iPhone Duo a provisional 5/10, the best score for a foldable. Both batteries (19.1 Wh total) release with electrically debonded adhesive inside metal shells, the outer display comes off intact, and the logic board is a single layer. The weak spot is the inner screen: a $999 out-of-warranty replacement and a hinge that still crunches with dust.
