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 communication and task management on a scale that was unimaginable just two decades ago. 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. It could not, however, surf the internet. That capability came in 2001, when developers connected smartphones to the 3G network, opening the door to mobile browsing as we know it today. The Computer History Museum’s technology timeline documents this progression in more detail at computerhistory.org.

The Simon introduced concepts like touchscreen input and personal information management that every modern device now takes for granted. At the time, most consumers had no framework for understanding what it was.

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

NASA’s Apollo 11 mission put humans on the moon using the Apollo Guidance Computer (AGC), a machine that operated at approximately 0.043 MHz with just 4 kilobytes of RAM. A report from NASA’s official history division confirms that today’s smartphones are significantly more powerful. 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.

That comparison is not just trivia. It reflects how much processing power now fits in a shirt pocket, and why smartphone-based medical and financial tools are becoming genuinely capable rather than merely convenient.

Smartphones Can Be Quite Addictive and Hazardous

A survey cited by EIN Presswire found that approximately 33% of smartphone users in the United States have nomophobia, the fear of being without one’s mobile phone. That number is significant on its own. What makes it more concerning is where those phones tend to travel.

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. Kitchens, elevators, restrooms, and workplaces present similar risks. Research published through the National Institutes of Health’s PubMed Central database suggests that the average phone carries roughly 100,000 bacteria, largely because most people never sanitize their devices even after visiting those environments.

Regular sanitization with alcohol wipes is a simple fix, but studies suggest most users skip it entirely.

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

Pulse tracking is now a baseline expectation on most smartphones, but the clinical potential extends far beyond heart rate. Researchers have modified smartphones to monitor ophthalmic health using built-in image recognition sensors and cameras that assess retinal condition. A diagnostic app developed with a high-precision microscope can help doctors identify suspected melanoma skin lesions accurately, a development covered in research indexed by the National Library of Medicine.

The potential for Alzheimer’s disease diagnosis is particularly striking. Traditional diagnosis often requires expensive PET scans or lumbar punctures. An app currently in development analyzes acoustic and linguistic speech features on a smartphone to detect Alzheimer’s in its early stages, with approximately 70–75% accuracy in distinguishing patients from healthy individuals. Earlier detection means earlier treatment and a better chance of slowing progression.

Scientists also believe that Parkinson’s disease can be managed more effectively with smartphone applications. Parkinson’s symptoms fluctuate frequently, and it is difficult for doctors to observe those fluctuations during a clinic visit. A smartphone app can track symptoms throughout the day and relay that data to physicians, as supported by research from the Michael J. Fox Foundation for Parkinson’s Research. That kind of continuous monitoring is difficult to replicate with any other tool.

The honest caveat here is accuracy. A 70–75% detection rate for Alzheimer’s is promising, but it also means a meaningful share of false positives and false negatives. These tools are best understood as screening aids, not replacements for clinical evaluation.

Smartphones Are Among the Top Timewasters for Most People

The numbers on social media consumption are hard to ignore. According to Business of Apps’ TikTok usage statistics, the average person spends around 95 minutes every day on TikTok alone. Many of those same users also spend time on Instagram and YouTube, often without any clear purpose.

Aimless scrolling is the defining feature of that behavior. Unlike reading or watching something specific, passive feed browsing tends to generate little satisfaction while consuming substantial time. That’s a tradeoff worth naming directly: the same device that can help you earn income or monitor your health can just as easily absorb three hours a day without delivering anything in return.

Your Smartphone Can Significantly Impact Your Income

There are real income opportunities tied to smartphones, whether you use Android or iPhone. Filming videos for YouTube, building an e-commerce store through Shopify, freelancing on Fiverr, and taking paid surveys are all activities that require nothing more than a phone and consistent effort. Some people have built full careers this way.

The other side of that equation is spending. Mobile apps are engineered to make purchases feel frictionless, and that design has a cost. The Consumer Financial Protection Bureau (CFPB) recommends setting clear budgeting rules for in-app purchases to avoid unintended debt accumulation. If you’re also managing a FICO Score or tracking your debt-to-income ratio (DTI), the ease of one-tap purchases on platforms like Apple Pay or Google Pay deserves the same scrutiny you’d apply to any recurring expense. Financial institutions including Chase and SoFi have built mobile budgeting tools specifically because impulse spending through apps is a documented pattern, not an edge case.

Your Smartphone Battery Can Last Longer Than You Expect

Battery drain is one of the most common frustrations with smartphones, and most of it is avoidable. Adjusting screen brightness and timeout duration reduces power consumption faster than almost any other setting change. Keeping your software current matters too. Both Apple iOS and Android releases regularly include battery optimization improvements, as outlined in Apple’s official battery health guidance.

Closing unnecessary background apps and enabling battery-saving mode during low-activity periods also help. So does managing connectivity features: Bluetooth, GPS, and Wi-Fi all draw power continuously when left on. Turning them off when not in use is a simple habit that adds up over the course of a day.

Smartphones Can Be a Threat to Your Safety

According to a report by the National Highway Traffic Safety Administration (NHTSA), smartphones have been linked to about 12% of accidents in the United States. Distracted driving is the most cited cause, but distracted walking contributes as well. The device that fits in your pocket can be genuinely dangerous when attention is split.

Digital security is a separate but equally real concern. The Federal Trade Commission (FTC) has documented the growing sophistication of mobile malware and phishing attacks that target financial details and sensitive personal data. Credit bureaus like Experian offer mobile monitoring tools for this reason, and the Federal Reserve and FDIC both publish guidance on protecting financial accounts accessed through mobile banking apps.

Location tracking presents its own risks. While useful for navigation, continuous location access can expose users to unauthorized surveillance or stalking. Then there is the mental health dimension: research published by the American Psychological Association (APA) links constant connectivity and social media use to anxiety and disrupted sleep. Being aware of these risks is the first step toward managing them. Responsible use habits matter more than any single setting or app.

Are smartphones more powerful than the computers used in the Apollo missions?

Yes, by a wide margin. The Apollo Guidance Computer ran at roughly 0.043 MHz with 4 KB of RAM. A modern smartphone operates at over 3 GHz with multiple gigabytes of RAM, a difference NASA’s official history division has acknowledged in published records. The comparison is useful because it illustrates just how much clinical and financial processing can now happen on a handheld device.

Can smartphones be used for medical diagnosis?

The capability is real but should be understood as supplemental to professional care. Apps have been developed to detect suspected melanoma lesions, monitor retinal health, and identify early-stage Alzheimer’s disease with 70–75% accuracy by analyzing speech patterns. Researchers also believe smartphones will assist in remote Parkinson’s disease monitoring. That said, a 70–75% accuracy rate means a meaningful number of incorrect results, so these tools work best as screening aids rather than standalone diagnoses.

How many germs are on the average smartphone?

Research published through NIH’s PubMed Central suggests the average smartphone carries roughly 100,000 bacteria. Users regularly bring their phones into restrooms, kitchens, and restaurants without sanitizing them afterward. Dr. Charles Gerba of the University of Arizona has documented similar contamination risks in high-touch environments.

How do smartphones cause accidents?

The National Highway Traffic Safety Administration (NHTSA) links smartphones to approximately 12% of vehicle accidents in the United States. Distracted driving is the primary factor, though distracted walking contributes to pedestrian incidents as well. Texting and scrolling while in motion are the behaviors most commonly cited.

What are the best ways to extend smartphone battery life?

Lowering screen brightness and reducing screen timeout make the biggest difference quickly. Disabling Bluetooth, GPS, and Wi-Fi when not in use helps throughout the day, as does enabling battery-saving mode and closing background apps. Both Apple iOS and Android platforms include built-in battery health management tools, and keeping the operating system current ensures access to the latest power optimizations, as Apple’s official battery guidance explains.

Can I earn income using just a smartphone?

Yes, though realistic expectations matter. Video creation on YouTube, freelancing through Fiverr, e-commerce via Shopify, and paid surveys are all viable starting points. Some people build full-time income this way, but most see it as supplemental at first. The CFPB advises monitoring in-app spending carefully regardless of income level, since the same mobile environment that enables earning also makes impulse purchases frictionless. If you are managing a FICO Score or trying to reduce your DTI, tracking mobile spending through a budgeting tool offered by institutions like SoFi or Chase is worth considering.

How do I protect my financial data on a smartphone?

The FTC recommends keeping software updated, avoiding public Wi-Fi for banking, and being skeptical of unsolicited links in texts or emails. Credit bureaus like Experian offer mobile identity monitoring as an added layer. The FDIC and Federal Reserve both publish consumer guidance on securing mobile banking access, including using strong, unique passwords and enabling two-factor authentication for any app tied to a financial account.
