Buying a phone case: what to look for in protection, fit and charging

A phone case should protect your smartphone from scratches, knocks and the effects of everyday mishaps. At the same time, it mustn’t get in the way of the buttons, camera or charging port. This is where common buying mistakes happen: a case may seem to fit your model but doesn’t, lose its shape after a short time or prevent you from using magnetic chargers.

These three pitfalls are particularly common:

  • Unclear model details: A case for the iPhone 16 Pro won’t necessarily fit the iPhone 16 or iPhone 16e. Models such as Pro, Pro Max and Plus also differ in dimensions, camera cut-outs and button positions.
  • Vague protection claims: Terms such as ‘shockproof’ or ‘military-grade protection’ don’t tell you much on their own. More useful details include the material, reinforced corners, raised edges and documented drop tests.
  • Overlooking charging compatibility: A case may support wireless charging without supporting magnetic attachment. If you want to use MagSafe accessories, you’ll need a phone case specifically described as MagSafe-compatible.

The key things to look for in a phone case

1. Exact compatibility with your smartphone

Before you buy, check the full model name in your phone’s technical specifications. Models to look out for include:

  • iPhone 16, iPhone 16 Plus, iPhone 16 Pro or iPhone 16e
  • iPhone 17, iPhone 17 Pro or iPhone 17 Pro Max
  • Samsung Galaxy S25 or Galaxy S25 Edge
  • Google Pixel 9 Pro XL

A well-fitting phone case needs to position the cut-outs correctly for the camera, speakers, microphone, USB-C port and side buttons. Even small differences can make the buttons difficult to press or block access to the charging port.

2. Assess the material and construction realistically

A silicone case usually feels soft and offers a good grip. Cases made from TPU (thermoplastic polyurethane) are flexible, retain their shape and are often easy to fit. In a hybrid design, a TPU frame is combined with a polycarbonate back.

Look for:

  • flexible sides that fit snugly,
  • reinforced corners or a documented shock-absorbing structure,
  • raised edges around the screen and camera,
  • a soft lining to prevent rubbing against the phone,
  • care instructions and information about possible discolouration.

A clear TPU phone case lets you see the device. However, the material can change over time if exposed to sunlight, heat or certain fabrics. A matt finish reduces visible fingerprints, but it isn’t automatically scratch-resistant.

3. Know the difference between wireless charging and MagSafe

Wireless charging works with many cases, as long as the material and thickness don’t significantly interfere with power transfer. MagSafe compatibility also means that built-in magnets help align and attach accessories.

When comparing products, make sure you distinguish between:

  • ‘Wireless charging compatible’,
  • ‘MagSafe-compatible’,
  • ‘Qi- or Qi2-compatible’,
  • magnetic attachment for wallets, mounts or chargers.

Follow the manufacturer’s safety instructions when using magnetic products. Magnetic-stripe cards and sensitive devices can be affected by magnets.

Fitting, care and lifespan

Before fitting the case, make sure your smartphone and the case are free from dust and sand. Slide the device into the case according to the manufacturer’s instructions, then check:

  1. Does the frame fit snugly around all four corners?
  2. Can you press the buttons without using extra force?
  3. Are the camera, speakers and charging port unobstructed?
  4. Does the wireless charger work as intended?

Clean your phone case with a soft, slightly damp cloth. Alcohol, solvents and abrasive cleaners can affect silicone, TPU or PU finishes. There’s no one-size-fits-all answer when it comes to how long a case will last. However, visible cracks, stretched edges, warping or a damaged camera frame are clear signs that it’s time for a replacement.

Frequently asked questions about phone cases

Which phone case protects against drops?

A shock-resistant phone case should have flexible sides, reinforced corners and raised edges around the screen and camera. Information about drop tests can also help you choose. However, it’s no substitute for getting the right model size, and no case can protect against every impact.

Is a silicone case better than a TPU phone case?

It depends on how you use it. Silicone often has a soft finish and feels comfortable to hold. TPU is usually more flexible and retains its shape better, making it easier to fit and remove. The frame design, edge height and fit are also important.

Does MagSafe work with every iPhone case?

No. An iPhone case may support wireless charging without allowing magnetic MagSafe attachment. If you want to use magnetic chargers, wallets or mounts, check that the product description explicitly states MagSafe compatibility.
