Spotted an IP rating on your phone’s spec sheet and wondering what it means?
IP rating stands for Ingress Protection. It’s all to do with the water- and dust-resistance level of a given device.
The higher the number’s value, the greater the resistance. If there’s an ‘X’ instead of a number that means no resistance to that particular.
Best phone IP rating: maximum numbers
The degree of dust resistance and water resistance isn’t on the same scale, though.
Maximum protection from dust is rated at 6. This means it’s dust tight.
Maximum resistance to water is rated at 8. This means it’s rated against full submersion at 3 metres ‘for long periods’.

ThereforeIP68 is the most protecteda device can be against both dust and water using this IP rating scale.
IP ratings: What the numbers mean
For object/dust protection:
5= dust protected, limited ingress permitted that will not interfere with device functionality
4= protected against 1mm objects (i.e. not dust - so even sand could be a problem)
For water resistance:
7= protected against water submersion of 1 metre for 30 minutes
6= protected against powerful jets of water from any direction
5= protected against jets of water from any direction
4= protected against splashes
If there’s no IP rating is there no protection?
Not necessarily. Motorola, as one example, has long coated its phone’s interiors with a resistant coating, but didn’t submit to the IP ratings system until more recently.
Also don’t rely on your IP rating as thinking your device is invincible. Having an IP68 rated device is great reassurance, but not a guarantee that nothing can ever go wrong.
