The iPhone X and iPhone XS share the same design language. The only upgrade Apple has made in terms of design on the latter is an improved IP certification but that’s about it. This change does not bring about any external changes to the iPhone XS. So does this mean cases for the iPhone X will be compatible with the iPhone XS?
The answer is a resounding yes! The iPhone XS shares the same dimensions as the iPhone X and since all port locations are also the same, iPhone X cases will fit the iPhone XS just fine. The latter is 3gms heavier than the iPhone X but this difference is unlikely to create any issues for cases with a kickstand or a slim profile.
Apple is known to reuse the same design on its iPhones for consecutive years to ensure they remain compatible with existing cases already available in the market.
If you are looking to upgrade to the iPhone XS from the iPhone X, you will now at least be glad to know that you won’t have to spend money on fresh cases for your new handset. This also means that case makers will be able to re-brand and sell their iPhone X cases for the iPhone XS. This is important since Apple has discontinued the iPhone X and replaced it with the iPhone XS.
Update: The iPhone XS has asymmetrical speaker design at the bottom, with the speaker grille on the left side being slightly shorter to accommodate for an antenna line. The camera hump on the iPhone XS is taller by a millimeter which might lead to slight fitting issues with certain iPhone X cases with tight tolerances.
