The 2000s were filled with rapid technological change, and with it came plenty of misconceptions. From fears about overnight charging and Wi-Fi radiation to myths about megapixels and computer defragmentation, users often believed misleading claims about their gadgets. Revisiting these myths today highlights how quickly technology evolves and how misinformation can shape our everyday habits.
1. Macs Don’t Get Viruses

Throughout the 2000s, Apple heavily marketed the idea that Macs were immune to viruses. While they were less targeted than Windows PCs, malware specifically written for macOS still existed. This myth gave users a false sense of security, often leading to lax cybersecurity practices.
2. Charging Overnight Ruins Your Battery

People often believed that leaving their phone plugged in overnight would “overcharge” the battery. Modern lithium-ion batteries automatically stop charging at 100 percent to prevent damage. The real issue is heat buildup, but overnight charging itself is not inherently harmful.
3. You Need to Defrag Your Computer Constantly

Windows users in the early 2000s swore by running disk defragmenters weekly for better performance. While it was useful for traditional hard drives, it wasn’t necessary that often. With modern SSDs, defragmenting is not only unnecessary but potentially damaging.
4. Using Too Many Apps Slows Down Your Internet

Many believed that having multiple apps or windows open would reduce internet speed. In reality, internet speed depends on bandwidth and network usage, not how many programs are running on your desktop. Unless those apps were actually consuming bandwidth, they had no effect.
5. You Can’t Use Phones on Airplanes

For years, airlines banned phone use due to fears they would interfere with flight systems. While older phones emitted stronger signals that could cause issues, the main concern was about network disruptions on the ground. Modern planes are shielded, and many now allow calls and Wi-Fi mid-flight.
6. Private Browsing Makes You Anonymous

People believed incognito or private browsing made them completely invisible online. In reality, it only prevents local device history from being saved. Your ISP, employer, or visited websites could still track you.
7. More Megapixels Means a Better Camera

In the early days of digital cameras and phones, advertisements pushed megapixel counts as the main measure of quality. Consumers thought higher numbers guaranteed better photos. In truth, sensor size, lens quality, and processing matter more than raw megapixels.
8. Turning Off Your PC Every Night Extends Its Life

Many users were told that shutting down their computer daily would prevent wear and tear. While it saves electricity, modern hardware is designed to handle constant uptime. Repeatedly powering on and off can actually stress components more than leaving it in sleep mode.
9. Cell Phones Cause Gas Station Explosions

Warnings were posted at gas stations telling drivers not to use mobile phones. The belief was that signals or static electricity could ignite gasoline vapors. However, no proven case ever linked a phone to such explosions, and studies have debunked this myth.
10. You Need Special Cleaner for LCD Screens

People were convinced that wiping an LCD monitor with anything other than expensive “special” cleaning solution would ruin it. In truth, a simple microfiber cloth and diluted water solution work just fine. The pricey branded sprays were mostly unnecessary marketing.
11. Wi-Fi Causes Health Problems

As Wi-Fi became widespread, rumors spread that its radio waves caused cancer or other health risks. Scientific research consistently showed no evidence of harm at the low power levels Wi-Fi operates on. Still, the fear persisted through the decade.
12. Closing Apps on Your Phone Saves Battery

A common belief was that force-closing apps kept your phone’s battery from draining. In reality, reopening apps consumes more energy than leaving them paused in the background. Modern mobile operating systems are optimized to manage resources efficiently.
13. Jailbreaking or Rooting Always Ruins Your Device

In the 2000s, jailbreaking an iPhone or rooting an Android was often seen as “breaking” the device permanently. While it voided warranties and introduced risks, it did not automatically destroy the phone. For many, it unlocked customization and features not otherwise available.
14. Bluetooth Drains Battery Drastically

Users avoided leaving Bluetooth on, believing it would rapidly drain their phone battery. While older Bluetooth versions consumed more energy, modern ones are designed to be extremely efficient. Keeping Bluetooth on has only a minimal effect on battery life today.
15. You Need to Safely Remove USB Drives Every Time

Everyone in the 2000s clicked “Safely Remove Hardware” before unplugging a USB drive, fearing data loss. This was important for older operating systems that used “write caching.” Today’s systems finish writing data almost instantly, making it much safer to unplug without that step.
16. Cell Phones Cause Brain Cancer

This fear was widespread as mobile phones became mainstream. Rumors claimed that holding a phone to your head for long periods exposed you to dangerous radiation. Extensive studies have shown no conclusive link between cell phone use and brain cancer.
