Hopes of highly water-resistant Pixel phones have, according to a reliable source we've trusted in the past, been dashed. Google's new handsets will be advertised as having IP53 dust and water resistance, which essentially amounts to almost no enhanced water resistance at all. For reference, the HTC 10 also has this rating, and is not marketed as being water-resistant.
The "3" in IP53 means a device will not experience damaging water ingress when upright at an angle not to exceed 60 degrees from vertical while being sprayed by relatively low-pressure (somewhere between 7-20PSI or 50 to 150kPa) water. This probably means very little to you phrased this way, but IPX3 is essentially saying the device will not experience water ingress (i.e., water won't get inside) when held at a relatively upward angle in your hand during use in very heavy rain or when lightly splashed.Read More
