This is the era of technology where all the gadget technology has reached its peak. The most common and useful gadget one can imagine is our cell phone. We are addicted to it at the extent that we tend to miss using it while we are in the bathroom. They have become non-separable part of our day to day life. Nowadays people don’t get amazed by hearing about a phone that can be used in water.

Water proof versus water resistant

Before going towards waterproof mobiles there is a small line differentiating between waterproof mobiles and water resistant mobiles. There no such waterproof mobiles exist because, with enough amount of pressure, water can penetrate into mobiles. And water with chemicals penetrates even more easily. That is why mobile phone sellers prefer to call them water resistant cell phones rather than water proof.

Water resistant principle

Theoretically, basically, there are major two ways used at laboratory and researchers for water proofing. One method is to provide barriers like covers and sealing that will stop entering water inside the ports. And the second method used is known as Nano coating in which mobiles are coated with particles in a vacuum chamber with a certain temperature that repels water entering the ports and openings.

Water resistant application in phones

Manufacturers use a thick sticky substance like glue at different stages for waterproofing that includes ports like USB, light, headphone jack. At some places like power and volume buttons, sim card tray glue is not convenient. For this purpose rubber gasket in forms like O rings, silicon rubber rings are placed inside the device which will expand on heating and fill the gaps. Speakers and microphones are the part of a mobile phone where the air is in contact with the atmosphere. So due to change in inside pressure of phone may allow entering through speakers. Manufacturers cover the speakers with a fine mash containing water resistant breathable fabric membrane that allows air flow to balance pressure.

Waterproof test

One complete water proof product has to pass certain tests and on the base of that owner’s product will be graded based on IPxx grading. Where xx is replaced with numbers depending upon water resistant quality which includes protection against water droplets, protection against water jet, protection against submerging under water.

Limitations of waterproof

All the major companies like Samsung, Sony, iPhone which provide water proof cell phones are providing guidelines and circumstances in which phones should be used. Cell phone manual includes information like how much water amount it can withstand. And how deep in swimming pool or in water phone would be water resistant. Moreover, companies also provide details how long a phone can withstand in water.

Water included with some chemicals can reduce water withstand capability of mobiles. That is why many mobile phone companies do not provide warranty in the salty water like the sea. One fun fact about water resistant cell phones is that touch screen cannot work under water. So one cannot use the phone it just provides protection in the water. The best water proof cell phone that is available nowadays include Samsung S8,iPhone 7 and Sony Xperia series.
