Things You Need to Know About Smartphones

Smartphones are one of the most widely used gadgets in the world, with over 6.92 billion users. They have become an integral part of our daily routine, enabling us to easily communicate with other people and perform various tasks. According to Statista’s mobile usage data, we now spend at least three hours each day on our phones and check them at least 58 times daily. Here’s some essential information you should know about smartphones.

Smartphones Were Invented in the ’90s But Couldn’t Access the Internet

The first-ever smartphone was the Simon Personal Communicator, developed by IBM. It was announced at the COMDEX trade show in Las Vegas in 1992, but it took two years to be released to the public. The device had a touchscreen user interface and could send and receive emails and faxes. However, it could not surf the internet. It wasn’t until 2001 that developers could connect smartphones to the 3G network, thus enabling smartphones to access the internet. You can read more about the Simon’s legacy in the Computer History Museum’s technology timeline.

The Computing Power of Your Smartphone Is Greater Than That of Some Spaceships

NASA’s Apollo 11 mission is a well-known historic event when humans first landed on the moon, thanks to the guidance of the Apollo Guidance Computer (AGC). In a report by NASA’s official history division, it has been confirmed that today’s smartphones are significantly more powerful than the Apollo Guidance Computer. The AGC operated at approximately 0.043 MHz with just 4 kilobytes of RAM, whereas a modern mid-range Android or iPhone processor runs at over 3 GHz with several gigabytes of RAM — a difference of many millions of times in raw computing capability.

Smartphones Can Be Quite Addictive and Hazardous

A survey cited by EIN Presswire has found that approximately 33% of smartphone users in the United States have nomophobia, which is the fear of being without one’s mobile phone. If you are one of these people, you likely carry your smartphone to some of the most germ-infested places, such as restaurants. According to Dr. Charles Gerba, a microbiologist at the University of Arizona, a single square centimeter of a restaurant menu can expose you to around 185,000 germs. Other highly germ-infested areas you are likely to visit with your smartphone include kitchens, elevators, restrooms, and workplaces. Generally, research suggests that our phones carry roughly 100,000 bacteria since we often take them to contaminated areas without proper sanitization measures, as detailed in studies published through the National Institutes of Health’s PubMed Central database.

Smartphones Are a Promising Tool for Cost-Effective Disease Diagnosis and Management in the Future

It is worth noting that most people use their smartphones to track their pulse rate. Smartphones are also currently being modified to monitor ophthalmic health. This is done using the built-in image recognition sensors and cameras on smartphones, which diagnose the retina’s health. Furthermore, with the help of a high-precision microscope, a diagnostic app has been developed that enables doctors to identify suspected melanoma skin lesions accurately, a development covered in research indexed by the National Library of Medicine.

Additionally, there is an app that is currently being developed to filter out the painful process of Alzheimer’s disease diagnosis, which involves expensive PET scans or painful lumbar punctures. The app will detect Alzheimer’s in its early stages by analyzing acoustic and linguistic speech features in individuals using a smartphone. It has been proven to be approximately 70–75% accurate in identifying patients with Alzheimer’s from healthy individuals. This app will help in the early treatment of the disease and prevent further progression.

Scientists also believe that Parkinson’s disease can be managed more effectively in the future with the use of smartphones. Parkinson’s symptoms tend to fluctuate frequently, making it difficult for doctors to monitor the fluctuations when patients are at home. However, a smartphone application can track the patient’s symptoms throughout the day and send the data to the doctors, a model supported by research from the Michael J. Fox Foundation for Parkinson’s Research. This will help doctors treat the patient more efficiently and effectively.

Smartphones Are Among the Top Timewasters for Most People

It has become a common practice for smartphone users to spend significant time scrolling through their phones. This is primarily due to the wide availability of social media platforms for entertainment, such as TikTok, Instagram, and YouTube. According to Business of Apps’ TikTok usage statistics, on average, a person spends around 95 minutes every day on TikTok, and most TikTok users also spend a considerable amount of time on Instagram and YouTube. However, most of the time spent on these platforms is unproductive, with users just aimlessly scrolling through content, often unaware of how much time they’re wasting.

Your Smartphone Can Significantly Impact Your Income

There are various ways you can earn extra income using a smartphone, whether it’s an Android or iPhone. For example, you can use your smartphone to film videos, take surveys, or do marketing. This can help you supplement your income or even establish a full-fledged career, all with the convenience of a few taps on your screen. Platforms like YouTube, Shopify, and Fiverr have made it genuinely possible to build income streams entirely from a mobile device. On the flip side, unchecked spending habits and the temptation of impulse purchases through mobile apps can lead to financial pitfalls. The Consumer Financial Protection Bureau (CFPB) recommends setting clear budgeting rules for in-app purchases to avoid unintended debt accumulation.

Your Smartphone Battery Can Last Longer Than You Expect

Most smartphone batteries tend to drain quickly. However, there are some recommended steps that can help you extend your smartphone’s battery life. Firstly, consider adjusting settings like screen brightness and timeout duration, as it helps minimize power consumption. You can also regularly update your phone’s software — whether you use Apple iOS or Android — to ensure it benefits from the latest optimizations and fixes, as advised by Apple’s official battery health guidance. Also, identify and close unnecessary background apps and utilize battery-saving mode, which adjusts performance settings during periods of low activity. Additionally, manage your device’s connectivity features, such as Bluetooth, GPS, and Wi-Fi, by turning them off when they are not in use.

Smartphones Can Be a Threat to Your Safety

According to a report by the National Highway Traffic Safety Administration (NHTSA), smartphones have been the cause of about 12% of accidents in the United States. This is because these devices are a major distraction, particularly when used while driving or walking. Moreover, the increasing sophistication of mobile malware and phishing attacks can compromise personal information, ranging from financial details to sensitive data — a concern documented by the Federal Trade Commission (FTC). Also, location tracking, while useful in some circumstances, might be a cause of privacy concerns and could expose you to potential stalking or unauthorized surveillance. Additionally, the addictive nature of social media and constant connectivity can contribute to mental health issues, including anxiety and sleep disturbances, as explored in research published by the American Psychological Association (APA). Therefore, it is crucial for you to be aware of these risks and adopt responsible smartphone usage habits to mitigate potential threats to your safety and well-being.
