With the phone market flooded with all manner of phones, it may be extremely difficult to pinpoint the right phone for you. This situation isn’t made any simpler with the fact that different phones specifications’ are increasingly becoming similar. If you are the sort of person who doesn’t buy into a manufacturer’s branding narrative and therefore like to analyse a phone’s specification in detail; you know that the devil is in the detail. Different phones may look extremely similar on the surface but on a closer examination worlds apart. This proves true for phone casing materials too. Each phone casing material has its pros and cons as you will see below.


Plastic is the most common phone casing material in the market. In fact there was a time when virtually all phones were made of plastic but that is not the case anymore. There are plenty other alternatives in the market. Nevertheless, manufacturers are yet to fully let go of plastic in making mobile devices. Frankly, it is no wonder why plastic has numerous benefits. For starters, it is cheap. This low cost often translates to the overall cost of the device. Thus, most of the devices made of plastic are cheap. Additionally, plastic is very scratch resistant so it hides most of blemishes on it. Its high impact resistance makes it considerably tougher than all other casing materials. Another benefit is compared to other materials it doesn’t suffer from network issues.

However, as with all else, plastic has its downsides too. Its biggest problem is associated with its greatest advantage. That plastic is associated with affordability and low-end devices, makes it often disregarded in the manufacturing of premium devices. This is mainly because for most people plastic is too cheap for a premium device. Another downside is that since plastic is a poor conductor of heat, it dissipates heat slowly. This slow dissipation can make devices with its casing function a tad bit slower than those made from other materials such as metal.


Metal used to be the previously preferred material for flagship phones not so long ago. The primary reason it was favoured was because it has a premium look and feel. Since metal is perceived as more expensive by the market, it appealed heavily to flagship’s target market. Another benefit of using metal was that since it was good conductor of heat it dissipates heat faster than its plastic counterpart in the case of overheating. Metal is also very malleable so manufacturers can be more adventurous with phones with metal designs.

On the other hand metal also has disadvantages. First, while it gives a phone a premium finish, it also makes a phone heavy. Metal is also very susceptible to scratches so it is wise to invest in a phone case for protective measure. Another downside is that in the event of overheating a phone can become too hot to touch. Lastly, phones with metal casing tend to suffer from network issues.


This is new casing manufacturers are using on their flagships or premium devices. Glass casing is the crème de la crème of phone casing in the market at the moment. What should be noted is this glass isn’t ordinary glass but corning gorilla glass which is not only durable but designed to survive bumps and ward off scratches.  Corning glass is attributed to the rise of glass adoption. Nevertheless, there persists some disadvantages of using glass such as since it is glass it is still fragile. It could shatter. Also, phones with glass casing have limited designs
