It might seem stupid to cover the shiny design of your brand-new smartphone with a bulk protective case. However, according to researches, half of the users break their devices. Keep in mind that “thanks” to Qi technology phone might be almost entirely covered with glass – not the strongest material. As for the front panel, tempered glass is typically merged with a touch screen. As a result, both should be replaced if the first one is shattered. Be aware of certain risks if you continue using it as it is.

But do phone cases protect your phone, and is there any reason for paying extra? Salesmen will recommend opting for the most expensive product, while cover haters will continue standing their ground. Let’s have an unbiased look.

Are cell phone cases necessary?

The answer to this question is who you are. If you don’t:

  • drop the things often,
  • have infants,
  • work near the water,
  • enjoy filming most extreme events of your life regularly,
  • work on a construction site,
  • love leaving your phone on the edge of the tables – congratulations, you probably don’t need any extra protection.

If anything of the above applies to you, then know that the tough case covering the whole phone works best. The device can still fall and break on occasion – however, the odds are small. On the other hand, if you know the probability of a heavy impact is high – it is better to protect the phone.

Pick the case suitable for you. If you drop things – opt for anti-shock, if you want to film underwater – go with a waterproof model. Keep in mind though that thin silicone cases will protect from scratches only. If the device falls, the cover will partially absorb the impact– but it might just not be enough.

No matter how pushy the salesperson is – think calmly. Do you need waterproof, and is it worth paying a hundred dollars for the feature you will never use? Check the internet forums and users’ reviews before purchase. Keep in mind that a significant portion of most optimistic opinions might be paid for by the manufacturers.

Does a phone case protect the screen?

Surely, this depends on the phone case type. Most cases are designed to prevent scratches only. If you use a thin plastic product, then the answer is probably not much. However, there are more productive, huge-looking anti-shock models with display protectors or even touch screens. Phone cases with a flip cover are good to protect the screen.

The screen typically shutters when the device falls:

  • face-down,
  • on one of the corners,
  • on edge.

Bumpers, for example, do cover both corners and edges. If the protective sides protrude, forming a so-called “lip,” they can (to a certain extent) save the device. Flip cases hide the entire screen, but they might fail to protect the edges.

The screen protector is mainly designed to protect the surface from scratches as well. The impact impulse in case of a fall will indeed distribute across the entire protector’s surface, which helps in some cases. Keep in mind that guard covers neither edges nor corners, though.

Additional accessories

If you want to have a firm grip in certain situations, look at the popsockets and their equivalents. This is one of the safest ways to take a selfie or use a large device with one hand. However:

  • it might leave a sticky residue when you take it off,
  • it will make your device thicker and heavier,
  • it might accidentally unstick when you use it.

There are also several other ways to increase the grip a little, such as vinyl skins and rubber tapes.

Pros and cons

The advantages are obvious – the case will protect the device from scratches and, depending on its type, might save from the impacts. Leather or tough phone cases with a flip cover help protect the screen. Let’s look at the disadvantages:

  • you have to pay for it,
  • it hides the entire smartphone,
  • it can facilitate overheating,
  • dirt can creep between the cover and phone finish scratching it,
  • it makes the device bigger and thicker.

To make a final decision, analyze yourself and don’t succumb to salesmen’s stories. Choose the protection that suits you best in all aspects. Keep in mind that there are people who never use any covers and don’t break their phones. The question is, though, – are you one of them?

Do phone cases cause overheating?

No, phone cases can’t make your phone overheat. In normal use of the phone in normal conditions, no case can cause the phone to overheat. However, some tight covers worsen heat dissipation, so they can slow down the phone’s cooling process.

The cell phone heats up at maximum load, especially when working continuously for long periods. In this case, the phone case can slow down the process of cooling the phone, but not critically. In the vast majority of such cases, the phone case can not damage the phone in any way.

External influences such as sunlight or high temperatures in the car where the phone is, especially if you are actively using it at the time, can cause the phone to overheat.

To cool the phone as quickly as possible, you should put it in a cool place, turn it off and remove the cover.

Are expensive phone cases worth it?

It depends on what you hope to get. Even an inexpensive case can go a long way toward protecting your phone. We recommend that you carefully read the technical specifications of the phone case and customer reviews, so you know whether this case is suitable for you.

Sometimes people buy a phone case as a piece of jewelry. So if you want a diamond phone case, it can’t be cheap.

Are cell phone cases necessary?

Absolutely not. First, modern phones can withstand quite strong impact, such as falling on a hard surface, shocks, immersion in water. Secondly, the touch screen is made of tempered glass, so it can withstand direct hits, falls and scratches.

However, using a case improves the user experience (it makes your phone less slippery) and increases the protection of your phone.


Do phone cases protect your phone?

Yes, almost any phone case protects your phone, but not against all possible threats. A thin silicone case protects your phone only against scratches, but an anti-shock case can save your phone even if you drop it.

Do you really need a phone case?

It depends on the phone owner. It’s recommended if you drop your phone often, or if you are going to sale it after buying a new one.

Can a phone case affect battery life?

Virtually not.

Why are the phones so fragile?

Modern phones can withstand falls on the pavement, their screen is scratch-resistant, some of them can be immersed in water… And yet it is a complex electronic device, not a brick.

Are flip phone cases annoying?

It’s up to you. Many people use flip cases and are happy with the fact that they protect the screen well.

How many times can you drop your phone?

It depends on from what height and on what surface the phone falls. The greater the height and the harder the surface, the greater the chance of smashing the phone.
Probably there is no person who would not have dropped his phone a dozen or a few dozen times a year.

How do you protect your phone from scratches?

The simplest way is to use any inexpensive phone case.

What is the best way to protect your phone screen?

You can use a tempered glass screen protector with a rugged or a tough phone case.


Here we have described in detail whether the phone cases work. If you want to use a cover to save your phone and protect the screen, use a rugged, leather, or tough case.
