On Friday, OnePlus released a teaser in a tweet for its upcoming OnePlus 7 Pro phone. The company dunked its smartphone in awater bucket despite the fact that the phone doesn't have an official water-resistance IP rating. And it is trying to show that even without the un-necessary rating phone has water resistance.
The company has taken a stance on IP ratings for resistance to water and dust. It suggests that getting the IP rating isn't cheap. To obtain official water and dust resistance the companies have to spend money and the smartphone manufacturers are transferring that cost down to its customers.
OnePlus seems confident enough that the OnePlus 7 Pro will have enough resistance against water that it can easily withstand a good water-bucket dunk. Still, the company doesn't suggest you to intentionally expose its upcoming smartphone to water. The fine print in the video says "Water resistant under optimal test conditions.
OnePlus makes no guarantees regarding water/liquid resistance." This means that if you are exposing your OnePlus 7 to water, you are responsible for any damage and the company isn't entitled to pay any money for the repair or bound to replace the phone if it does more harm to the phone.
This kind of written warning isn't a new thing. You may find the same printed text on phones that have a high official IP rating. Apple's support page has a disclaimer about any water damage which says, "if liquid damages an iPhone or iPod (for example, coffee or a soft drink), the service for the liquid damage isn't covered by the Apple One-Year Limited Warranty."
You have to buy AppleCare Plus for $6 per month and pay another $100 for the repair, which is what you have to pay even if the iPhone doesn't have an official IP rating. To be fair, the official IP rating is just for peace of mind. In the case of OnePlus Pro 7 you have to take its word for it.
