Remember back in the year of 2013, when Sony announced the new Xperia Z series and loudly told the world that their devices could be used underwater? They even made the promotion video with people using their phone in baths and swimming pools.
However, after multiple testing reports by all the YouTubers and Tech Reporters throughout the years, we know that there’s no such thing as completely waterproof. At least not at the current point of technology development. At the same time, we can see more and more water resistant smartphones in the market since then.
So you may ask, what does “Water Resistant” and “Weather Proof” mean? What does the standard mean when people say the phone is IP68 weather proof?
What is an IP rating?
The IP (Ingress Protection) rating is an international standard for measuring a device’s levels of protection from dust and fresh water. The first digit in the IP code indicates the level of protection against solid objects, including dust. The second digit refers to what degree the device is protected from fresh water.
|0||No special protection||No special protection|
|1||Protected against solid objects > 50 mm in diameter.||Protected against dripping water.|
|2||Protected against solid objects > 12.5 mm in diameter.||Protected against dripping water when tilted up to 15 degrees from normal position.|
|3||Protected against solid objects > 2.5 mm in diameter||Protected against spraying water.|
|4||Protected against solid objects > 1 mm in diameter.||Protected against splashing water.|
|5||Protected against dust; limited ingress (no harmful deposit)||Protected against low-pressure water jet spray for at least 3 minutes.|
|6||Dust tight.||Protected against heavy jet spray for at least 3 minutes.|
|7||/||Protected against the effects of immersion in up to 1 metre of water for 30 minutes.|
|8||/||Protected against the effects of continued immersion in water at depths greater than 1 metre. The exact conditions are specified for each device by the manufacturer|
It is often stated by smartphone manufacturers that their IP ratings are set according to the results they collected from the experiments tested under a strictly controlled laboratory environment. Thus, they strongly recommend users to keep their devices from water.
Also, they will require you to strictly keep your covers closed; this includes the covers for the micro USB port, the SIM card slot and the memory card. If you left them loose and accidentally dropped you phone into water, you are definitely not getting covered by the warranty.
To conclude, by “Water Resistant”, “Waterproof” and “Weather Proof”, the smartphones are implied to be protected against solid objects and fresh water to a certain extent; they are not protected from salt water, and should not be brought under the sea. Moreover, remember to pat them completely dry and shake off any possible water in the gaps of the phone if you bring your phone for a swim.
