Our smartphones, laptops, and gadgets have become an essential part of daily life, but simple mistakes can damage them or expose us to cyber threats. From avoiding cheap chargers to securing your data, learn the best ways to protect your devices and keep them running efficiently.
Technology has revolutionised how we communicate, work, and entertain ourselves. However, many people unknowingly damage their smartphones and laptops or expose themselves to digital risks due to poor habits. Whether it’s using unsafe chargers, ignoring updates, or leaving your phone unlocked, these common mistakes can compromise both security and performance. In this guide, we’ll explore key tech habits you should avoid and how to keep your devices in top condition.
Avoid Cheap Chargers – They Could Ruin Your Device
When a charger breaks or gets lost, it’s tempting to buy a low-cost replacement. However, cheap knock-off chargers can harm your battery, causing overheating or even short-circuiting. In rare cases, poorly made chargers have led to serious injuries due to electrical faults. Always opt for reputable brands or manufacturer-approved alternatives to ensure your device’s safety.
Ignoring Updates Can Make You a Target for Hackers
Software updates aren’t just about new features—they include essential security patches, bug fixes, and performance improvements. Delaying updates can leave your device vulnerable to cyberattacks. Hackers exploit outdated software to steal sensitive information. To stay protected, ensure your phone, laptop, and apps are always running on the latest versions.
Turn Off Bluetooth and Wi-Fi When Not in Use
Leaving Bluetooth and Wi-Fi on continuously not only drains battery life but also increases security risks. These open connections act as entry points for cybercriminals, allowing them to intercept data or access your device remotely. To minimise risks, turn off Bluetooth and disconnect from public Wi-Fi when not in use.
Public Wi-Fi Can Be a Cybersecurity Nightmare
Free public Wi-Fi may seem convenient, but it often lacks encryption, making it easy for hackers to intercept your passwords, banking details, and personal data. Some cybercriminals even set up fake networks to steal information. If you must use public Wi-Fi, consider a VPN (Virtual Private Network) to encrypt your connection and keep your data secure.
Never Leave Your Phone Unlocked
Your smartphone contains sensitive information, from personal messages to saved passwords. Leaving it unlocked is like leaving your house with the door wide open. Set up biometric authentication (fingerprint or facial recognition) or a strong passcode to prevent unauthorised access.
Eating and Drinking Near Your Laptop Can Be Risky
Crumbs stuck under keys or accidental spills can cause keyboard malfunctions, short circuits, or even permanent damage. Liquids are particularly dangerous, as moisture can reach internal components. Keep food and drinks away from your laptop to avoid costly repairs.
Avoid Keeping Your Phone in Your Back Pocket
Sitting on your phone might not seem like a big deal, but it puts immense pressure on the screen and internal components. Even if there are no visible cracks, repeated pressure can cause internal display damage, blurry spots, or touchscreen issues. Keep your phone in a front pocket or bag instead.
Leaving Disks in Your Laptop Can Damage Your Drive
If your laptop has a disk drive, avoid leaving CDs or DVDs inside when transporting it. Movement can cause the disc to misalign, jam, or damage the drive mechanism. Also, tilting the laptop while a disc is spinning can increase wear and tear.
Overheating Can Shorten Your Phone’s Lifespan
Excessive heat is one of the biggest threats to your smartphone’s battery. Leaving your phone in direct sunlight, using it while charging, or running too many apps can cause it to overheat. If your phone gets too hot, turn it off and let it cool down before using it again.
Never Leave Your Laptop in a Hot or Cold Car
Just like chocolates, laptops don’t handle extreme temperatures well. Leaving a laptop in a hot car can damage internal circuits and cause the plastic components to warp. On the other hand, extreme cold can freeze the liquid crystals in your screen, causing permanent damage. Always store your laptop in a temperature-controlled environment.
Avoid Using Your Phone While It’s Charging
Many people use their phones while charging, but this slows down the charging process and generates excess heat, which can reduce battery lifespan over time. For a healthier battery, allow your phone to charge undisturbed and unplug it once it’s full.
Power Off Your Devices Regularly
Smartphones and laptops benefit from periodic shutdowns. Turning your device off at least once a week helps reset background processes, clear temporary files, and improve performance. It also reduces wear on the battery, extending its lifespan.
Never Place Your Laptop on a Soft Surface
Laptops rely on airflow to stay cool, and most intake vents are on the bottom. Placing your laptop on a bed, couch, or pillow blocks ventilation, leading to overheating and potential hardware damage. Instead, use a flat, hard surface or a cooling pad to keep air flowing freely.
Beware of Counterfeit SD Cards
Fake SD cards are a common scam. They often provide less storage than advertised and can cause data loss or slow performance. Always buy SD cards from reputable brands and avoid deals that seem too good to be true.
Never Install Apps from Unknown Sources Downloading apps from unofficial websites increases the risk of malware, spyware, and hacking attempts. Some pirated apps contain hidden viruses that can steal your personal information. Stick to official app stores like Google Play Store and Apple App Store to ensure security.
