The Computing Technology Inside Your Smartphone

There has never been a better time to live other than the 21st century, where thanks to technology, smartphones have made life way much easier than ever before. We do not have to travels miles to relay a message. Not only have smartphones offered a solution as a communication medium, but has also played a major role in encouraging information dissemination and provision of several online services. As the years go by, smartphones are becoming more and more useful, taking the functions of a calculator, photographer, videographer, and so much more.

How much do you understand about the computing technology that powers your smartphone? So many components within a phone work together to work, and without understanding computing technology, it may be difficult to understand how your smartphone works. Here’s a look at the inside of your smartphone:


The display function of your phone is made possible by either LCD or LED.

LCD-based display – a backlight usually shines through polarizers and some filters. The crystal display that is seen is then manipulated by all the lights, which then displays different colors on the other side of the screen. As a user, you do not see all the light, but some of it that are generated by the backlight that you cannot see.

LED-based display – the LEDs, also known as light-emitting-diodes, get things done. Ideally, they generate different colors in three categories, that is, red, green, and blue. This means that unlike for the LCD-based displays, the display on this one produces the light themselves. The advantage with this is that the pixels that are produced by the LEDs are only active when activated. Ideally, if you were to switch off the phone, the screen will be black, and no activity would be going on through that period. Such are phones that have an extended battery life than the others.


Talking of batteries, you may want to know how they work. Today, the batteries used in smartphones use lithium-ion technology, instead of how it was back in the day, where they used nickel-based cells. Thanks to that advancement, calibration is no longer a thing to worry about when talking about modern mobile phones.

Memory and storage

People differ in their preference of smartphones, mostly due to memory and storage. Every day, people generate tons of data, and with technology providing for several media for sharing these data, then you understand why memory and storage matters in smartphone usage. RAM and ROM are both critical aspects of a smartphone, without which, they cannot function.

RAM – different kinds of RAM are used for different devices. Technically, LPDDR3 or LPDDR4 are the common types used in mobile phones. Of the two, LPDDR4 is better and faster. However, even better RAM would be LPDDR4X, even though it is pretty expensive to produce and is available for flagship phones, because of their speeds and efficiency.

ROM – it is the internal memory of the phone, where users get to store their data. Over time, smartphones have rapidly been built to accommodate more internal storage, from as low as 2GB, to now, as high as 256GB. Once you buy your phone for the first time, consider the amount of space you will need, depending on the need you expect your phone to meet. Ideally, the advertised ROM will not necessarily be all the available space you can use, because you have to give some space to the pre-installed apps, not to mention, the operating system.

‘System-on-a-chip’ or SoC

A system-on-a-chip is a single chip on your smartphone that integrates all the components of a computer necessary to make it run. SoC is used on mobile technology because of its ability to use up very little power. That said, you cannot misunderstand the SoC only to mean that it is the processor of the phone. You would be shocked to know that this part of a phone consists of its CPU, video processor, GPU, display processor, and LTE modem. Some types of SoCs used on mobile phones include, Qualcomm, Kirin, MediaTek, and Samsung, to mention a few. All of them, however, depends on ARM’s architecture, from which the different phone companies can use architectural licenses to make their processors.


Communication via smartphones is only made possible by modems, which allow the users of these gadgets to receive and send text messages, as well as make and receive calls. The different types of SoC unique to different phone brands and companies all have their modems. The various companies are still competing over getting the best modems, for the best, fastest, and most efficient user experience.


Smartphones are loved for their touch sensitivity and responsiveness to commands. The sensors used in phones are different to serve different purposes, usually the following five:

  1. Accelerometer – responsible for customization features in phones, for example, shaking it to change the music.
  2. Gyroscope – works together with the accelerometer to sense rotation of the phone, for example, when watching a video clip with a tilted phone.
  3. Proximity Sensor – actively noted when a user brings a phone close to their ear during a call, so that the screen automatically locks, to prevent unnecessary touches and commands.
  4. Ambient Light Sensor – responsible for fine-tuning the brightness of the screen based on the surroundings
  5. Digital Compass – responsible for navigability, by helping the smartphone find the North direction from any location

The above is a breakdown of the computing technology that helps power up your smartphone. However, new innovations in smartphones such as the foldable phone continue to change and increase the computing technology in your smartphone.
