Smartphones: We love them; but man, do we do some dumb things with them. According to a survey commissioned by T-Mobile, nearly half of all smartphone owners have had their phones lost, stolen or damaged. For smartphone owners who have damaged their phones, 37 percent scratched the screen, 29 percent spilled a drink on it, 29 percent dropped it down the stairs and 20 percent dropped it in the toilet (ewwwwww!)

Protecting a smartphone with a case is a no-brainer for a lot of smartphone owners. Other smartphone owners, however, don't think smartphone case protection is all it's cracked up to be. For one, no smartphone case -- or at least not one you'd want to carry -- can completely protect your phone from damage. Smartphone cases also add bulk to the phone and can hide cool aspects of the phone's design. If you're not super careful, a case can even damage your phone. Dirt and debris can get caught between the case and the phone and scratch the phone's finish. The smartphone cases that offer the best protection can be expensive, especially since you usually have to get a new one each time you get a new phone. Finally, smartphone cases can interfere with docking. It's a pain to have to take your phone out of its case every time you want to hook it up to your car or home stereo.

On the other hand, there are a lot of good reasons to use a smartphone case. If you're good about keeping it clean so dirt and grime don't build up between the phone and the case, a smartphone case will usually do a good job of protecting the phone from scratches. A smartphone case can also provide some protection if you drop your phone (though you shouldn't use a case as an excuse to launch your phone off your roof). Though a smartphone case may not make your phone look quite as cool, it can help keep all parts of it working. Dropping a phone may not result in much visible damage, but without a case it's easy for the smartphone's camera lens to get broken. Plus, with some smartphones having sleek-but-slick-finishes, a grippy case can help keep you from dropping the phone in the first place. There are a few waterproof cases on the market for smartphones, but even most basic cases should buy you a few extra seconds to grab your phone out of the path of an expanding puddle of spilled beer (your friends are such lightweights).

So, do smartphone covers really protect phones from damage? To a degree, they do -- but you still need to be smart about how you take care of your phone. I recommend not using it anywhere near a toilet.

Smartphone Cover FAQs

Do smartphone covers protect phones from damage?
Smartphone covers provide adequate protection to phones. They mostly protect the corners, back, and edges of the phone. A good phone case cover will mitigate the impact of shock and vibration when the smartphone is dropped.
How to protect a phone without a case?
The best thing you can do is being more careful with your phone when it’s not in its protective case. Try to keep the phone in a safe place where it’s not at risk of falling to the floor.
What is the best material for a phone case?
Absorbent materials that can mitigate shock and vibrations such as rubber and silicone are excellent choices for smartphone cases. In this sense, plastic cases are not ideal because they do not absorb shock away from the device.
What are some disadvantages of phone cases?
The biggest disadvantage of phone cases is that they make your phone look less aesthetic. They might make it harder to press buttons (if the cases haven’t been specially designed for your phone). Cases can also trap debris and dust, which can then cause scratches on your phone.
Are cheap phone cases good?
Cheap phone cases are good as long as they are made of the right materials and are compatible with your phone’s dimensions. Do not buy leather cases since they’re not good at protecting phones.

Author's Note: Do Smartphone Covers Really Protect Phones From Damage?

Before I had my daughter, I scoffed at parents who let their kids play with their smartphones. When my daughter started reaching for my iPhone at just three months old, however, I knew I was in for it. According to the smartphone damage survey, one in four parents has had their smartphone damaged by their kids. Though my kid doesn't play with my phone, she does grab for it while I'm using it, and the extra grip provided by my case helps me hang on to it. I've even seen specialty cases sold in the baby section of some big box stores to add extra kid-proof protection to smartphones and tablets. My little casemate iPhone case may not be able to stand up to the damage my kid is capable of handing out, but for now, I figure every little bit of protection helps.
