A Smartphone is a cellular telephone with an integrated computer and other features not originally associated with telephones such as an operating system, web browsing, and the ability to run software applications. A smart phone is a portable device that combines mobile telephone and computing functions into one unit. They are distinguished from feature phones by their stronger hardware capabilities and extensive mobile operating systems, which facilitate wider software, internet (including web browsing over mobile broadband), and multimedia functionality (including music, video, cameras, and gaming), alongside core phone functions such as voice calls and text messaging. Smart phones typically contain a number of metal–oxide–semiconductor (MOS) integrated circuit (IC) chips, include various sensors that can be leveraged by pre-included and third-party software (such as a magnetometer, proximity sensors, barometer, gyroscope, accelerometer and more), and support wireless communications protocols.

Early smart phones were marketed primarily towards the enterprise market, attempting to bridge the functionality of standalone personal digital assistant (PDA) devices with support for cellular telephony, but were limited by their bulky form, short battery life, slow analog cellular networks, and the immaturity of wireless data services. These issues were eventually resolved with the exponential scaling and miniaturization of MOS transistors down to sub-micron levels (Moore’s law), the improved lithium-ion battery, faster digital mobile data networks (Edholm’s law), and more mature software platforms that allowed mobile device ecosystems to develop independently of data providers.


Phones that made effective use of any significant data connectivity were still rare outside Japan until the introduction of the Danger Hiptop in 2002, which saw moderate success among U.S. consumers as the T-Mobile Sidekick. Later, in the mid-2000s, business users in the U.S. started to adopt devices based on Microsoft’s Windows Mobile, and then BlackBerry smart phones from Research In Motion. American users popularized the term “Crack Berry” in 2006 due to the BlackBerry’s addictive nature.[40] In the U.S., the high cost of data plans and relative rarity of devices with Wi-Fi capabilities that could avoid cellular data network usage kept adoption of smart phones mainly to business professionals and “early adopters.”

Outside the U.S. and Japan, Nokia was seeing success with its smart phones based on Symbian, originally developed by Psion for their personal organizers, and it was the most popular smart phone OS in Europe during the middle to late 2000s. Initially, Nokia’s Symbian smart phones were focused on business with the Eseries, similar to Windows Mobile and BlackBerry devices at the time. From 2006 onwards, Nokia started producing consumer-focused smart phones, popularized by the entertainment-focused Nseries. Until 2010, Symbian was the world’s most widely used smart phone operating system.

The touch screen personal digital assistant (PDA)-derived nature of adapted operating systems like Palm OS, the “Pocket PC” versions of what was later Windows Mobile, and the UIQ interface that was originally designed for pen-based PDAs on Symbian OS devices resulted in some early smart phones having stylus-based interfaces. These allowed for virtual keyboards and/or handwriting input, thus also allowing easy entry of Asian characters.[43]

By the mid-2000s, the majority of smart phones had a physical QWERTY keyboard. Most used a “keyboard bar” form factor, like the BlackBerry line, Windows Mobile smart phones, Palm Treos, and some of the Nokia Eseries. A few hid their full physical QWERTY keyboard in a sliding form factor, like the Danger Hiptop line. Some even had only a numeric keypad using T9 text input, like the Nokia Nseries and other models in the Nokia Eseries. Resistive touch screens with stylus-based interfaces could still be found on a few smart phones, like the Palm Treos, which had dropped their handwriting input after a few early models that were available in versions with Graffiti instead of a keyboard.

There is no denying the fact that smart phones have drastically altered our everyday lives. From our working and entertainment habits to the way we communicate, socialize and organize things, everything has changed.

Here are some of the major positive effects of mobile phones on our everyday life:

Improved Communication:  The key reason why smart phones were invented was to fulfill one of the basic human needs i.e. to stay connected. Needless to say, the technology has done wonders for humanity. By enabling us to connect with anyone, anywhere, and at any time, smart phones have completely revolutionized the telecommunication industry.

Help Us Stay Organized: With multi-tasking becoming the norm of modern day life, it often becomes difficult to keep track of everything. This problem can be resolved if you pay a little heed to the small device in your pocket or bag. There are many mobile phone apps that can help you manage things and stay organized.

Since earthquakes are common in Japan, cell phone companies send free notifications to their users, whenever there is a warning of a natural disaster. This helps people to take preventive measures and reduce the chances of loss of lives.

Increased Awareness: By helping us stay connected with each other and with the world, mobile phones help people to stay up-to-date on the political, economic, and social issues affecting the world. The availability of information also contributes to increasing awareness about certain issues that was previously lacking. For example, technological advancements have really increased awareness about mental health. Due to the increased awareness, people can now empathize with those suffering from mental health issues rather than simply labeling them, as happened in the past. In view of the widespread usage and positive effects of mobile phones, it wouldn’t be wrong to say that smart phones have also become our, diaries, offices, televisions

After only about a decade, smart phone technology is so successful that businesses and employees have trouble imagining a day without them. Besides making phone calls, nearly all smart phones today can natively provide directions through GPS, take pictures, play music and keep track of appointments and contacts. Through the installation of apps, the list of possible smart phone uses multiplies by tens of thousands and grows longer every day. Your business can make good use of this rapidly evolving technology.

  • Differing Communication Options

Old school cell phones can call and text. While this can get your message across, smart phones allow you multiple ways of communicating with your staff, customers and suppliers. Not only can they call, text and IM, these communication tools give you access to email, immediate photo sharing, video calling and video conferencing. You can chair a staff meeting from anywhere you have phone service! You can also remain connected through social networking sites like Twitter, Face book and LinkedIn.

  • Exploring the Web

How many times each day do you consult the internet for news or other information essential to your business? At first, web browsing happened at a desk in an office, where a wire could reach a PC. Wireless access and laptops moved the web to pretty much anywhere in the house or office, but smart phone technology, including broadband wireless, has sent the web onto the subway, into cars and to the park — wherever there is cellular coverage. What’s more, the latest smart phones can display nearly as much of the internet as PCs, including business news sites and streaming high definition videos.

  • From Several Devices to One

Once, you might have needed an entire bag to carry around all the devices needed for daily business activities. You would need your pager, cell phone and your PDA. You might also need an MP3 player, an e-book reader, a camera and a GPS device. Through miniaturized hardware that packs a processor, speakers, a camera, a GPS receiver, a Wi-Fi adapter and a high definition touch-sensitive screen into a cell-phone-sized device, a smart phone puts all of this functionality into your pocket. One of your workers can easily search for directions to a client’s business, read a sales flier before a meeting starts and transmit an ad sale to your office from via a mobile hotspot.

  • Availability of Many Applications

The late twentieth-century saw an explosion of computer applications. The early twenty-first century brings hundreds of thousands of smart phone apps. The sensors built into the smart phone as well as its portability and programmability have made it a device with almost limitless applications. Beyond the tons of games (your workers do need a break now and then), there are numerous productivity apps available to save a good idea when inspiration strikes, organize meeting notes, and hosts of other possibilities. You and your staff can keep fit with health and fitness apps to track miles walked and the calories you’ve consumed. Internet radio and podcasting apps put you in touch with whole new worlds of audio. Compass apps, leveling apps and flashlights provide handheld utilities. Apps that let you paint, modify photos or create music tap into your creativity.


Smart phones have radically changed people’s lives. Before people have to take extra effort in sending messages or they buy a camera just to take pictures. Today, these functionalities are integrated into one, rectangular – revolutionary technology that keeps getting smarter and smarter every day. Since then, smart phones are never found out of reach from people. According to statistics, almost half of the population owns a smart phone. In a 2016 survey conducted by the Bank of America, 96% of the millennials aged 18 to 24 years old said that smart phones are very important for them. 93% of them even stated that smart phones are more important than deodorant and toothbrush. The survey also found out that an individual checks his or her smart phone every 6.5 minutes.

Everything has its advantages and disadvantages. In the section, let us know how we can benefit from smart phones and at the same time, what the disadvantages of smart phone technology are.
