Yes, in fact the iPhone XS and iPhone XS Max have better waterproofing than any previous iPhone model.
Apple has upgraded the rating on iPhone XS and iPhone XS Max to IP68, which means the devices can rest in liquids two meters (6.6 feet) deep for approximately 30 minutes without any problems.
Yes, not only do all of the iPhone X models have Face ID but all three next-generation models (iPhone XS, XS Max and XR) are equipped with faster Face ID than the iPhone X.
The iPhone XS may include more advanced features than its predecessor the iPhone X but it has retained the same dimensions, including thickness. The iPhone XS is 5.65 inches (143.6 mm) x 2.79 inches (70.9 mm) x 0.30 inch (7.7 mm). It weighs 6.24 ounces (177 grams) and has a 5.8‑inch display, also the same as the iPhone X.
