Top tech myths you need to stop worrying about

Let’s bust some tech myths wide open! I’ve heard them all, and it’s time to set the record straight to keep you ahead of the game.

Myth: 5G causes cancer.

Fact: Relax, folks. The World Health Organization (WHO) and other health agencies have done extensive research and found no adverse health effects linked to 5G. It uses the same type of nonionizing radio frequencies as 4G and Wi-Fi, neither of which damage our DNA or cells.

Myth: Closing apps on your phone saves battery.

Fact: Both iOS and Android OS manage background apps efficiently, keeping them in a low-power state. Reopening an app consumes more energy than resuming it from this low-power state. Instead, lower your screen brightness, disable unnecessary notifications and use battery-saving modes.

Myth: More RAM means a faster computer.

Fact: While more RAM can improve multitasking, upgrading your hard drive from an HDD to an SSD will boost performance by reducing load times.

Myth: You should always let your phone’s battery drain fully before recharging.

Fact: Older nickel-cadmium batteries suffered from the “memory effect.” Completely draining a lithium-ion battery in today’s newer phones will shorten its lifespan. Lithium-ion batteries work best when kept charged between 20% and 80%.

Myth: Incognito mode keeps your browsing activity completely anonymous.

Fact: Incognito mode only prevents your browser from saving your history, cookies and form data. It doesn’t hide your activity from your ISP, your employer (if you’re using a work computer) or the websites you visit. For more comprehensive privacy protection, use a VPN.

Myth: You should always use your monitor’s highest resolution.

Check your car for a hidden tracker

A guy who bought a Toyota Corolla discovered a hidden GPS he thinks the dealer installed. When the battery ran out of juice, he checked the OBDII port and there was a tracker. Here’s how he found the tracker.

Is your tracker running low on juice? No need to buy a new one for $29 — just replace the battery for a few bucks!

Check your car: A guy who bought a Toyota Corolla discovered a hidden GPS he thinks the dealer installed. When the car’s battery died, he checked the OBDII port and there was a tracker. Uh, why? Theories range from making it easier to steal to selling info on driving habits to insurance companies. Here’s how he found the tracker.

100-degree heat

Cuts your EV’s driving range by 31%. It’s all based on the outside-versus-inside temp; 100 degrees is 30 degrees above a comfortable 70-degree interior. A 10-degree winter day puts you 60 degrees below 70, and so it sucks up 51% of your battery to keep you warm. That’s nearly a full percentage point per degree!
