IP Ratings Explained: Which Water and Dust Protection Do You Need

TL;DR

  • IP ratings tell you how well a device resists solids and liquids using two digits: the first for dust, the second for water.
  • Common phone ratings: IP67 means dust tight and protected against immersion up to 1 m for 30 min, IP68 usually means better water resistance with specified depth and time from the manufacturer.
  • IP ratings do not guarantee protection against high pressure water, saltwater, shampoo, or long term exposure. Treat them as insurance for accidents, not a license for underwater use.
  • Buying checklist by use:
  • City use and occasional rain: IP53 to IP67 is typically fine.
  • Poolside or accidental drops in water: IP67 or IP68 recommended.
  • Regular beach or diving use: look for devices rated for specific depths and consider purpose built gear.

What is an IP rating

IP stands for Ingress Protection. The code has two numbers:

Manufacturers may add a trailing letter for additional info, but the two digits are what matter for everyday buyers.

  • First digit 0 to 6 describes protection against solids and dust. 6 means dust tight.
  • Second digit 0 to 9K describes protection against water. Higher means better liquid ingress protection.

Common ratings explained

  • IP53: limited dust protection and protection against spraying water at an angle. Good for light outdoor use.
  • IP67: dust tight and protected against temporary immersion up to 1 m for 30 min. Popular on many flagship phones.
  • IP68: dust tight and protected against continuous immersion under conditions specified by manufacturer, often greater depth or longer time than IP67. Exact limits vary, so check official specs.

How testing works and what it does not cover

  • Tests are performed in controlled lab conditions using fresh water. For water tests, factors like temperature, pressure, and water composition are standardized.
  • Tests do not usually cover saltwater, chlorinated pool water, soapy water, high pressure jets, or extended exposure to moisture.
  • Drops and microcracks from normal use can degrade water resistance over time, so performance may decline.

Real world meaning for everyday use

  • Rain and splashes: devices with IP54 and above handle this without issue.
  • Accidental submersion: IP67 or IP68 will likely save your device from a short dunk.
  • Pools and beaches: salt and chemicals accelerate corrosion and can bypass seals. Rinse with fresh water after exposure and avoid charging until fully dry.
  • Cleaning: avoid alcohol based sprays and high pressure cleaners. Use a damp cloth and follow manufacturer guidance.

Warranty, repairs, and manufacturer claims

  • Many warranties exclude water damage even for IP rated devices, or require inspection. Always check warranty terms.
  • Independent repair and wear and tear can void water resistance. Replacing screens or opening the device can remove factory seals.
  • Some manufacturers will service water damage, others will not. Keep proof of purchase and check service policies.

Choosing the right IP rating for you

  • Casual users who want peace of mind: IP67 is a strong baseline.
  • Frequent outdoor users or families with kids: IP68 provides extra margin, but know the specific depth and time limits.
  • Active water exposure or underwater photography: consider ruggedized devices with explicit depth ratings or dedicated waterproof housings.

Quick buying checklist

  • Check the exact IP code and the manufacturer note on depth and duration.
  • Read warranty terms for water damage coverage.
  • Verify service network and costs for seal restoration after repairs.
  • Avoid used phones with unknown repair history when water resistance matters.
  • If you plan pool or beach use, rinse device with fresh water and dry thoroughly before charging or storing.

Bottom line

IP ratings are a useful shorthand to compare water and dust resistance, but they are not absolute guarantees. For most users, IP67 gives reliable protection against accidental immersion and day to day moisture. IP68 adds extra safety, but always check the exact limits and treat water resistance as one factor among battery life, camera, and longevity. Use additional precautions for saltwater, pools, and extended underwater activities.
