If you intend to make a selfie in the shower or take a few photos, while under water in the pool this summer with the help of your HTC 10, we would advise you to refrain from doing so. According to HTC manager, Jeff Gordon, HTC has 10 certified IP53 certification, which makes it very unfriendly to water and dust ingress.
In summary, rating IP53 technically means that the first digit, 5, refers to solids. In this case, 5 means that HTC 10 does not protect completely against dust, although a certain amount of dust will not get into the smartphone and will not affect its operation. For example, you can easily place the device on a dusty table top, but do not leave it in the sand.
The second number, 3, is a liquid. With assessment 3, NTS 10 is protected against water spray at an angle up to 60 ° vertically. For clarity, we are talking about the spray of water, and no water flows. In other words, a slight fogging or condensation in the bathroom, not in any way affect the performance of the smartphone.
Of course, compared with the Galaxy S7, the smartphone is clearly losing, but the HTC 10 has a number of advantages that make the device attractive.
