5 ways you’re ruining your expensive phone, laptop, tablet, and TV |

Years ago, I put a tempered glass screen protector on my phone. The best part is when you drop your phone, and the glass gets nicked, you simply remove the protector, and it’s good as new. Here’s a link to the brand I have used for years, ESR.

Our devices are big investments. You need to treat your tech well to get your money’s worth. Regular maintenance is one way to stay ahead of the game. Tap or click for six checkups to do now to avoid a hefty repair bill later.

Based on calls to my show, emails, and questions posted on my website’s tech support forum, here are five common mistakes that could cost you.

1. You’re charging too much

Do you keep your phone plugged in all the time? Apple says that when your iPhone “remain(s) at full charge for prolonged periods of time, battery health can be affected.”

Android phone manufacturers, including Samsung, say the same. “Do not leave your phone connected to the charger for long periods of time or overnight.” Huawei says, “Keeping your battery level as close to the middle (30% to 70%) as possible can effectively prolong the battery life.”

The official word is to keep your phone charged — but not fully charged. Get in the habit of unplugging your tech after it is fully charged.

2. You wait too long to charge your laptop

Laptop batteries have a finite number of charge-discharge cycles. If you frequently let your battery entirely run out of juice, it affects the charge-discharge cycle and diminishes its intended lifespan.

Your laptop battery can also lose efficiency another way. Let’s say you regularly charge your laptop from 30% to 50%, or about 20% each time you charge it. Well, do that five times and you’ll have completed one battery cycle because you’ve charged your laptop 100% in total.

A good rule of thumb is to keep your battery charged to at least 40% most of the time. Tap or click here to check your laptop’s battery health.

3. You go with the cheapest option

If you lose your charger or a USB cable gets frayed, resist the temptation to buy the cheapest replacement. The few dollars you save on a low-cost substitute may very likely negatively affect your device’s performance.

One-size-fits-all charger and cable makers don’t want you to know that often their products do not have the proper voltage needed to work with your specific device. Why does that matter? Your battery may end up not getting the juice it needs to charge fully. Worse, it may erode the battery’s life.

Cheap chargers can be dangerous to you, too. Many generic phone chargers are less likely to meet established safety and quality testing guidelines than their name-brand counterparts, leading to severe shocks and burns.

Spend a little more on getting a replacement charger and cable from the devices’ manufacturer or certified third-party makers. Tap or click for a solid third-party recommendation for iPhone and Android.

Today’s phones are fairly rugged. They can generally resist water, dust, and a bit of water. But leaving your device in a hot car or out in the sun can cause serious damage. Not only can it cause the battery to leak or overheat, but it can also cause data to be lost or corrupted.

Extreme cold temperatures also wreak havoc on your phone. Lithium-ion batteries can stop discharging electricity in freezing temperatures, leading to shortened battery life, display problems, and even cracking the display glass.

Is your tech sparkling clean or covered in crumbs and smudges? It’s not just about cleanliness, either. Dust and dirt can do severe damage to computers, TVs, and other expensive electronics.

Here are some essential tools I keep on hand to maintain my devices:

● Compressed air: This is especially useful when you need to clean tight quarters and inside difficult-to-reach crevices. If you don’t like the waste of regular compressed air, try an electric air duster.

● Isopropyl alcohol: Avoid household cleaning products on your electronic devices. A good rule of thumb is if you would use it to clean your kitchen, it’s not appropriate for your computer or electronics.

● Cleaning wipes: If you don’t want to mess with alcohol or water, try a cleaning wipe. I buy these all the time.

● Distilled or purified bottled water: Tap water could leave mineral spots and stains.

● Soft cloths: Lint-free is your friend; don’t use paper towels or tissues that scratch and leave particles behind. If you have a 100% cotton cloth, that works, too. Here’s an affordable pack of clothes I’ve purchased a few times.

● Toothbrush: A soft toothbrush can be used on hard-to-reach areas and spots that need light scrubbing.
