Guide: Questions you should ask yourself before buying a waterproof mobile phone case

Are you thinking about buying a waterproof mobile phone case, but are a bit overwhelmed by the choice and the different offers? Then you've come to the right place, because we'll explain what you should look out for when buying waterproof mobile phone cases.

What do you want to use your waterproof mobile phone case for?

Before buying a waterproof phone case, you should think about what you want it to do. For example, if you just want to go snorkelling and take some underwater photos, your phone case doesn't need to be as powerful as it would be if you were going diving.

If you want to use your mobile phone case for diving, you should pay attention to the specified maximum duration and water depth. Some models are not suitable for long dives. Before you buy a waterproof phone case, you should already know its purpose.

What are the alternatives to a waterproof phone case?

Instead of using a waterproof mobile phone case, you can of course also protect your smartphone in a normal waterproof bag. However, you will not be able to use your phone under water, as these bags are usually not transparent and contain several items.

However, if you are in a boat and only use the waterproof bag for safety, you can of course take your phone out to use it. Then, of course, a waterproof bag could also make sense.

Decision: What types of waterproof phone cases are there and which one is right for you?

When buying a waterproof phone case, you can first decide whether you want to get a waterproof phone case or choose a waterproof hardcase phone case:

  • Mobile phone cases
  • Hardcase mobile phone cases

Below, you can read about the advantages and disadvantages of each model.

What are the advantages and disadvantages of a waterproof phone case?

A waterproof phone case is basically nothing more than a small plastic bag in which you can store your phone. Thanks to a particularly thick material and certain closure mechanisms, water cannot penetrate the bag and the contents are protected.

  • Space for additional items
  • dust-proof
  • suitable for various phone models
  • enables clear photos
  • More awkward than the case
  • limited use of the button
  • not suitable for everyday use

The biggest advantage of the mobile phone case is that you can use it alternatively for other things or protect other valuable items, such as credit cards or cash, from water in addition to your smartphone. The mobile phone cases are not only waterproof, but also protect your mobile phone from dust deposits in the case. The transparency of the mobile phone cases also gives you a clear view of your display and ensures sharp photos and videos.

What are the advantages and disadvantages of a hard case mobile phone cover?

A waterproof hard case works like a normal mobile phone case, but is usually a little thicker and particularly robust. These phone cases usually also protect your smartphone from drops and dust.

  • Can also be used for everyday use
  • unrestricted display and button functions
  • drop-resistant
  • No extra space
  • water can collect in front of the camera
  • only suitable for certain phone models

In contrast to the waterproof mobile phone case, you can use all button and display functions of your mobile phone without restriction with the cover. Using the display through the plastic cover is usually much more awkward and requires more patience. You can also take beautiful underwater pictures with the waterproof hard case, as long as you make sure that the camera remains free from water accumulation.

Buying criteria: Use these factors to compare and evaluate waterproof phone cases

In the following, we would like to show you which factors you can use to compare and evaluate waterproof mobile phone cases. This will make it easier for you to decide whether a particular waterproof mobile phone case is suitable for you or not. In summary, these are:

  • Sealing performance
  • Size
  • Holder

In the following paragraphs, we will explain what the individual criteria are.

Waterproofing performance

The density is of course the essential criterion for a waterproof mobile phone case. Most manufacturers guarantee waterproofness with the help of elaborate or double closures. Before you use your waterproof mobile phone case, you should test it in advance.

In most cases, the manufacturer's instructions are included with the product. Otherwise, you should put a handkerchief or something similar into the bag, close it and leave it in the water for some time to see if your product is really waterproof.


The size of the phone case should of course be adapted to your device. Otherwise, the size of the mobile phone case is especially important if you want to take additional things with you. Then you should choose a model that offers enough space. You should also consider which mobile phone models you want to use your waterproof mobile phone case for. If you want to use different sized models, a phone case is also an option.


Most waterproof phone cases have a holder so that you can carry the case as close to your body as possible under water. You can usually attach either a loop or a handle to your case. A loop can be very helpful if you want to hang the case around your neck and need as much freedom of movement as possible when taking photos.


Underwater photos can also be taken very well with your mobile phone camera if the mobile phone cover is very clear and transparent. (Image source: / Guasi Fuentes)

A handle, on the other hand, is suitable if you want to attach your mobile phone to a piece of clothing while filming. Of course, this has the advantage that you carry your phone very close to your body and therefore cannot lose it so easily.

Interesting facts about waterproof mobile phone cases

Finally, we would like to answer a few important questions about rose hip powder and how to take it. You will find out whether you can take underwater photos with a waterproof mobile phone case, what options you have if the case does not live up to the manufacturer's promises and whether you can make your own waterproof mobile phone case.

Can I take underwater photos with a waterproof phone case?

The main reason for buying a waterproof phone case is that people want to take underwater photos.

Did you know that you can take better underwater pictures if you make a video and later take screenshots of the best parts? The constant movement underwater often blurs individual photos, so you can just make a whole video and use screenshots from it later.

This is no problem with a transparent waterproof phone case. You should make sure that the material does not impair the picture quality. It should be as clear as possible and not visible in the photo.

You can also take beautiful underwater photos with a waterproof hardcase. However, you should make sure that no water collects in front of the lens so that you don't have any unwanted water spots on your photo.

What options do I have if the cover does not deliver what the manufacturer promises?

Most waterproof phone cases come with instructions on how to check the waterproof performance of the case. You should therefore carry out a test before using the cover. If the case does not seal, most manufacturers guarantee a refund and replacement of the leaking case. To be on the safe side, however, you should find out what guarantee the manufacturer promises before you buy.

Can I make a waterproof phone case myself?

If you want to save money on a waterproof mobile phone case, you can of course make your own. This works with various plastic bags or balloons.
