Sony Xperia Z2 vs. Samsung Galaxy s5: Which smartphone can survive more when (accidentally) immersed in water?

Buying a unit should not be as easy as choosing a popular brand or your favorite color. You should always check which one stands out when it comes to specs and features. You should also consider your lifestyle. If you are always on-the-go, you have to get the handset with a longer battery life. When you are near water or you know yourself as careless, you may want to check which among the phones have water resistance - with the highest rating, to be specific.

Per statistics, liquid damage is the "second leading cause of smartphone failure, the first being damaged screens". Over 30% of busted units are, by accident, damaged by water, drinks, showers, toilets, and rain.

Sony Xperia Z2 vs Samsung Galaxy s5: Both are waterproofed phones, but which has a better IP rating?

Galaxy s5 is certified IP67; Z2 received two IP ratings as it is able to comply with two waterproofing standards - IP55/IP58. Typical buyers are not aware what these ratings are so basic understanding is necessary.

In IP rating chart, IP stands for Ingress Protection. The first number refers to the level of protection from dust and the second number refers to the level of protection from water.

IP55, therefore, as far as water resistance is concern, says that the unit is "protected from low pressure water jets from any direction". IP58, on the other hand, points out that Sony Xperia Z2 is "protected from long term immersion up to a specified pressure". Meanwhile, IP67 of Samsung Galaxy S5 indicates that the handset is "protected from immersion between 15 centimeters and 1 meter in depth".
