Phone, laptop and games console cases: how to choose the right fit, material and protection

Protecting a new device sounds straightforward. In practice, unclear model details, exaggerated protection claims and unsuitable materials often lead to the wrong purchase. A phone case, for example, might fit the standard version of a smartphone but cover the camera cut-out on the Pro or Plus model. With a laptop case, it’s not just the screen size that matters: the internal dimensions are key.

This buying guide explains what UK online shoppers should look for in cases for phones, laptops and games consoles. It focuses on objective product details such as compatibility, material, dimensions, fastenings and access to ports.

Common pitfalls when buying a case

1. Screen size is mistaken for internal dimensions

A size range such as ‘15 to 15.6 inches’ isn’t always enough when choosing a laptop sleeve. Two devices with the same screen size can differ in width, depth or thickness. So check the internal dimensions of the case and compare them with the measurements of your laptop.

The exact model name is also essential for e-readers and games consoles. A Nintendo Switch 2 case won’t necessarily fit older console models.

2. ‘Shock-resistant’ doesn’t automatically mean protection in every everyday situation

Terms such as shock-resistant case, ‘robust’ or ‘drop protection’ shouldn’t be considered in isolation. Specific design features are more useful indicators:

  • reinforced corners or edges all the way around
  • raised edges around the screen and camera
  • flexible TPU layers or a combination of TPU and polycarbonate
  • non-slip surfaces
  • padded linings in laptop bags

A slim, clear phone case can help protect against scratches and minor knocks, but by design it won’t offer the same level of protection as a more heavily padded case.

3. Wireless charging isn’t always compatible with every accessory

For a MagSafe case, the seller should clearly state that it has a built-in magnetic ring or supports MagSafe accessories. ‘Wireless charging’ alone doesn’t tell you whether the case provides magnetic alignment.

You should also check whether you need to remove the case before charging. With some products, charging performance can be affected by the material thickness, magnet position or an incompatible charger.

The key things to consider

Fit and device model

Don’t just search for ‘Samsung Galaxy case’ or ‘iPhone case’. Look for the full model name. Examples include Samsung Galaxy S25 case, Samsung Galaxy A55 case, iPhone 17 case and iPhone 17 Pro case. Camera layouts, button positions and device dimensions can vary across a product range.

For laptops, compare the external and internal dimensions. The Inateck sleeve for 15 to 15.6-inch laptops, for example, has internal dimensions of 37,5 × 25,8 × 3 cm. It also has a pocket for accessories such as cables, cards or a mouse.

Material and construction

A TPU case is flexible and usually easy to fit. TPU is often used for clear phone cases. Polycarbonate is more rigid and is often combined with TPU. A silicone case feels soft in your hand; you should also consider the lining, edge coverage and how easy it is to clean.

Laptop sleeves can have several layers. According to the product details, the Inateck model is made from polyester, soft lining, EPE, EVA and non-woven fabric. The outer surface is described as splash-resistant. This doesn’t mean it’s fully protected against being submerged in water.

Everyday practicality

Check that ports, speakers, cameras and buttons remain accessible. For a games console case, dock compatibility, grip and access to controls are also important. If you commute, a carry strap, accessory pocket or magnetic fastening may be more useful than an especially slim design.

FAQs about cases

Which phone case protects against scratches in everyday use?

A well-fitting case with raised edges, covered corners and precise cut-outs can help protect the back, edges and screen during everyday use. TPU and TPU-polycarbonate combinations are common materials for clear phone cases. However, the level of protection depends on the design, how you use the case and its condition.

Can you charge wirelessly with a MagSafe case?

It depends on the model and its design. A case marketed as MagSafe-compatible should be described by the seller as supporting both magnetic compatibility and wireless charging. Check the charger’s specifications too. The function may be limited if the case is damaged or very thick.

How long does a laptop case last?

Its lifespan depends on the zips, stitching, material and how much it’s used each day. Replace your laptop case if the padding, fastening or lining is visibly damaged. Regularly clearing out dust and cleaning it carefully can help keep it in good condition.
