What’s Inside Your Smart Phone?

Inside your mobile

Have you ever wondered just what’s inside your smartphone device? Since their launch, smartphones have revolutionized our lives. Helping us to stay in touch, providing hours of entertainment and even letting us shop from wherever we are, these clever devices have become deeply ingrained in our everyday lives.

Here, we’ll look at some of the main components within a smartphone and how they work.


The battery in a smartphone is one of its most important components. Providing the power required to run the phone, they are typically made with lithium-ion technology. This eliminates the issues with testing and calibration which were prominent with older nickel-based batteries.

However, that doesn’t mean to say they are without their issues, and when handling the battery component, you should be careful due to how volatile they can be.


Another obvious important component in a smartphone is its display. Over the years, the display capabilities have been significantly enhanced. Newer technology has made phone displays sharper and more in-depth, providing beautiful results. You can either purchase LCD or LED displays.

The LCD displays use a backlight which shines through polarizers and filters. This means the light is actually generated behind the display. With LED displays, it’s all down to light-emitting diodes. They produce the pixels you see and are considered more battery-friendly than the LCD displays.

There are new smartphones using the OLED display as well.

Logic Gates

One of the lesser known components of a smartphone are logic gates. You can purchase physical logic gates from companies such as RS, but the ones found in your mobile device are largely digital.

They are used to control the electric current flows within the device as it flows around the circuit. There are actually millions of logic gates contained within smartphones, featuring in numerous components such as the display, CPU and power management.


Ever wondered how your smartphone can send and receive texts and calls? It’s all down to a clever modem. Every manufacturer has their own unique modem used within their devices. Some are much faster than others, and manufacturers are consistently trying to develop and release faster chips to boost their performance.

The above is just some of the most important components in a smartphone. There are so many different components involved with ensuring a smartphone works properly, with some you’ve likely never even heard of. Of course, the bigger the smartphone, the more components it’s going to use.
