Apple did the thing. The first foldable iPhone has arrived with the new iPhone Duo delivering a pretty compelling package for interested foldable customers who don’t want to give up on iOS. It also addresses a durability gap that few others have managed with IP68 protection but, like Pixel 11 Pro Fold, that’s only a temporary rating for the iPhone Duo.

In a footnote on Apple’s iPhone Duo listing, the company admits that the IP68 dust/water protection won’t last forever:

iPhone Duo is splash, water, and dust resistant and was tested under controlled laboratory conditions with a rating of IP68 under IEC standard 60529 (maximum depth of 6 meters up to 30 minutes). Splash, water, and dust resistance are not permanent conditions. Resistance might decrease as a result of normal wear…

It’s a bit less of a thought for a typical slab-style smartphone, as the dust/water resistance there shouldn’t change drastically unless there is external damage. But, with a foldable, there are moving parts to account for and, as such, the rating may wane over time.

Apple’s not alone.
