What to look for before buying a Waterproof phone case?

IP ratings

How long and how deep a device can stay in the water is marked with an IP rating. It displays the standard mark in all cases. Moreover, You will get its ratings in the Product description. There are several types of IP ratings, such as P67, IP66, and IP65.

  • The IP65 rating means that at a depth of three meters at a pressure of 30 kPa, it will stay good for 15 minutes, and the water density should be 12.5 liters per minute.
  • IP66 means 100 liters per minute in water at a pressure of 100 kPa up to 3 m deep; the phone case will stay good for 20 minutes, and no water will enter into the phone.

IP68 ratings are mainly given on the most expensive phones. The Samsung Galaxy S20 Plus phone has an IP68 rating. So before looking at the waterproof phone case, you need to consider the IP ratings.


Since waterproof cases are always helpful, so many people love to watch movies in their spare time. They can undoubtedly choose the case with the kickstand. It didn’t seem mandatory because you can continue to work with any object that is close to you.

Shock Absorption

The waterproof case fits tightly with the phone. That is why these cases protect your phone from falls and drops. Even some wild-type waterproof cases protect your phone from breaking up to 2 meters. You need to thanks Shock absorption technology cause it protects your phone from breaking.

So before buying a phone case, you must examine shock absorption technology.


Phone cases are better than waterproof pouches because they suit with a phone. But some phone cases are much thicker. These look like monsters. When I hold my phone, the actual feeling of the phone does not come in handy. So always try to choose a thin case.

For this, I would recommend choosing SpiderCase for Samsung Galaxy S20 Plus. I feel a lot more comfortable using it.


It would be best to choose organic materials such as plant-based. But these are rare. Instead, you can take TPU and silicone cases. Phone cases made with these types of materials are much softer and easier to use.


It’s a private matter. But as an s20 + user, I would recommend the first one. Also, You like everything. But, the phone cases are affordable and easy to use.

Case vs. Pouch: Which will be better for you?

Before buying a waterproof case, you must decide which one to take. There are many differences between the two entities. Both have advantages and disadvantages.

The waterproof case usually fits with the phone, and you can always use it. On the other hand, the waterproof phone’s pouches are small plastic bags; they look like chips packets.

Suppose you are walking on the footpath and suddenly it starts raining. Your waterproof case will also protect the phone at that time. Also, many people like to use the phone in the washroom. Water is everywhere in the bathroom, so waterproof phone cases are suitable at this moment.

You can’t always use Pouch. Pouches can only use when you go to the swimming pool and the beach bath. Again, the price of phone cases is higher than Pouch. The phone cases are the best because they fit with the phone, touch is responsive, and can be used anytime. It is wise to spend a few dollars to make the best choice.
