A smartphone has a more powerful CPU, more storage space, more RAM, greater connectivity options and larger screen than a regular cell phone. Also, smartphones are equipped with innovative sensors like accelerometers or even gyrscopes. Accelerometers are responsible for displaying screens in portrait and landscape mode, while gyrscopes make it possible for games to support motion-based navigation. Smartphones combine the features of a mobile phone, such as the abilities to place and receive calls, send and receive text messages with features of a personal digital assistant such as GPS navigation, video camera, video games, event calendar, internet access, and more.
An Operating system (OS) is a software that runs our desktop computers and laptops and manages their resources and memory when they are being used for multitasking. All smartphones come with an operating system. Because smartphone operating systems are so integrated with the look, feel and function of a mobile phone, many people base their choice of device around which operating system it uses. When purchasing a smartphone, you should endeavor to check out which operating system the phone you fancy has, and this operating system type can be found in the handset’s specifications information. Most smartphone operating systems are open source software, which means there are no restrictions on what you can download on it, or who can develop its software. It also means that a large community of companies and developers maintain it and contribute toward developing newer versions of it.
Android is an open source operating system developed by Google, primarily designed for touchscreen devices such as smartphones and tablets. It is the most common type of OS that powers most smartphones. The Android OS powers all Android devices. It is like an underlying software that instructs your device on what to do.

The Google play store allows users to browse, download and update applications published by Google and third-party developers. Mobile device manufacturers also control which version of the Android operating system powers their device. Also, some Android devices have big screens and fast processors while other Android smartphones have tiny displays, slow CPUs and few extra internal features. The Android OS has several versions such as: Android 1.5 Cupcake, Android 1.6 Donut, Android 2.1 Éclair, Android 2.3 Froyo, Android 2.3/2.3.7 Gingerbread, Android 3.0/3.2.6 Honeycomb, Android 4.0/4.0.4 Ice Cream Sandwich, Android 4.1/4.3.1 Jelly Bean, Android 4.4/ KitKat, Android 5.5/5.1 Lollipop, Android 6.0/6.1 Marshmallow and Android 7.0/7.1 Marshmallow, being the most recent version.

What is a smartphone without a good battery life? Many factors including the screen size, processor and operating system determines how long a smartphone lasts on a charge. A good smartphone is considered to have a good battery life if it lasts longer than 9 hours of straight LTE surfing. Smartphones could have removable or non-removable batteries so it is important to take this to note. Also, you should take into consideration the battery’s mAh (Milliamp Hours). mAh is the total amount of energy a battery can store at one time; It is commonly used to describe the energy charge that a battery will hold and how long a device will run before the battery needs recharging. Battery mAh differs from one smartphone to another. Some smartphones have a battery mAh of about 2,400, others 3, 500, some others 4,200mAh and so on.
When purchasing a new smartphone, the amount of internal storage is one of the key factors that influences the decision to buy a smartphone over another. When considering the memory specifications of any smartphone, it is paramount to understand the difference between internal and external or expandable memory. Internal memory is the manufacturer-installed storage space, usually 16, 32 or 6 GB, where the operating system, pre-installed apps and other system software is installed. The internal storage cannot be expanded by the user, and if there is no expansion slot on the phone, you have no choice but to make do with the limited internal storage. The expandable memory is a removable MicroSD card or similar. Some smartphones come with the expandable card already inserted. Not all smartphones give the user the ability to add more storage by using a SD card, so it is important you check out the storage capability of the smartphone before buying it.

In recent time, they are much more than phones and personal organizers, they are also music and video players; cameras and camcorders; web browsers and more. On a smartphone, there are components such as the central processing unit, memory, graphical chipset, RAM, interface controllers, voltage regulators and more. Since there isn’t much space on the phone to accommodate all of these, all these are incorporated into a single chipset referred to as a System-on-a-Chip (SoC). A key component of the SoC is the CPU. Most companies use a CPU (Central Processing Unit) based design from ARM which handles most things you experience on your smartphone. ARM is a combination of the company itself, a microprocessor architecture and processor core. Another key component of the SoC is the GPU (Graphics Processing Unit) which processes graphical and visual data responsible for things such as rendering web pages and gameplay. The SoC also incorporates a number of other sub-processors such as video encoders and decoders, camera operation, and audio playback. A major element found in the main processor that reads and executes instructions is the core. Cores in recent times have evolved from a single-core processor tom dual-core devices, quad-core processors and even hexa-core and octa-core processors in smartphones. There are also Qualcomm Processors and Snapdragon processors. When shopping for a smartphone, the processor specs are useful to get a sense of what the device is capable of doing. If you are looking for speed, go big with a multi-core processor.
