Mobile phone accessories include any hardware or software that is not integral to the operation of a mobile phone as designed by the manufacturer.

Cases are based in the display inches (i.e. 5 inch display). There are different types: [1]

  • Pouches and sleeves
  • Holsters.
  • Shells.
  • Skins
  • Bumpers
  • Flip cases and wallets
  • Screen protection and body films
  • Ultimate protection

Holsters are more commonly used alone for devices that include rubberized padding, or are made of plastic and without exposed rigid corners.

Standing case improves user experience, being specially recommended for multimedia, videos and audio.[2] Folio case is a combination case, stand, and keyboard (USB for OTG smartphones or bluetooth keyboard). [3]

Heavy duty cases are designed to protect from drops and scratches [4]

The newest trend in cell phone accessories are skins and design covers, for the dual purpose of protection and personalization. These are the result of the relatively "naked" designs produced by manufacturers such as Apple, where the metal and glass components of the device are exposed and vulnerable to damage. These are distinct from holsters, in allowing use of the device while in the case, but in many instances include a belt clip or other device giving it the functionality of a holster. They are made of hard plastic, rubber, or in the newer market adhesive-backed vinyl pieces. Vinyl skins can be ordered on many websites and come pre-cut to fit your cell phone or even another electronic device. There exist two different types of vinyl material, calendared or cast, with the latter being more expensive. In short, calendared vinyl is expected to only be used for short durations while cast vinyl is used on a more long term basis. Calendared vinyl also tends to shrink in the heat, and fade. Cast vinyl avoids these problems, but costs up to 250% more (which still is a very cheap total cost). While the technology of these adhesive-backed skins continues to improve, the most up to date technology comes from 3M. The company has manufactured a cast vinyl product that they call "Controltac". This vinyl cover maintains a more glossy look and provides an air release channel that prevents bubbles during placement. The more popular is the cast vinyl because of the range of designs. There are even some which are 3D.[citation needed]

Custom mobile case[edit]

Customized Phone Cases are becoming increasingly popular with the trend towards personalisation.

Different companies have different methods of printing on cases, some utilize sublimation for printing on mobile phone cases,[5] other methods include inkjet printed skins and Dye-Sublimation 3D printing methods.

Designer Cover[edit]

Some cells have a cover that you can take off and replace with a designer cover. There is a release button on the cover, and you just press the button, and it pops right off. Then you replace it with the new cell cover. If your phone doesn't have a removable cover then you can purchase a slip on or snap on cover. This type of cell covers come in leather, vinyl, silicone, or hard plastic.


Functional cases can include an external battery or an external keyboard (in a similar way to Windows Surface tablets).

Chargers and external batteries[edit]

Cell phone chargers have gone through a diverse evolution that included cradles, plug-in cords and, finally nowadays, in the standarized micro-USB device.

External batteries can be included in the case (power case).[6] Also external batteries can include rubber suction. [7]

Smart lens[edit]

Smart lens are high quality lens, performance sensor, optical zoom and control, – coupled wirelessly with the smartphone (compatible smartphones must be Wi-Fi enabled). They are compatible with most smartphones.[8]


Micro USB to HDMI cables are used in smartphones with MHL.[9]
