As the temperature climbs towards summer, your devices feel it too. Heat is one of the most damaging things for phones, tablets, laptops, and computers — it slows them down, shortens their lifespan, and in extreme cases causes them to shut down or fail entirely. A few simple habits can keep your gear running cool and reliable through the hottest months. Here's what to know.
Why Heat Is So Harmful
Electronics generate heat as they work, and they're designed to shed it through vents and fans. When the surrounding air is already hot, that becomes much harder, and components run hotter than they should. Over time, excessive heat degrades batteries, stresses internal parts, and can cause permanent damage. In the short term, devices often slow themselves down deliberately to avoid overheating — which is why your computer might feel sluggish on a hot day.
Keep Devices Out of Direct Sun
This sounds obvious, but it catches people out constantly. A phone left on a car dashboard, a laptop used on a sunny patio, or a tablet sitting on a windowsill can heat up dangerously fast. Never leave devices in a parked car on a warm day — the interior can reach temperatures that damage electronics and batteries quickly. Keep your gear in the shade and out of hot cars.
Give Laptops Room to Breathe
Laptops draw in cool air and expel hot air through vents, usually on the sides and underneath. Using a laptop on a bed, couch, carpet, or your lap blocks these vents and traps heat. Always use it on a hard, flat surface, and consider a laptop stand or cooling pad if yours tends to run hot. Keeping the airflow clear makes a real difference.
Clear Out the Dust
Over months and years, dust builds up inside computers and laptops, clogging fans and vents and trapping heat. A device that's started running hot and loud is often simply choked with dust. A proper internal clean can bring temperatures right back down and restore quiet, cool operation. It's one of the most worthwhile bits of maintenance there is.
Watch for the Warning Signs
Your devices will tell you when they're too hot. Look out for fans running constantly and loudly, the device feeling hot to the touch, sudden slowdowns, unexpected shutdowns, or battery warnings. A phone that displays a temperature warning needs to be cooled down before use. Ignoring these signs risks longer-term damage.
Cool It Down Safely
If a device does overheat, switch it off and let it cool naturally in a shaded, well-ventilated spot. Don't put it in the fridge or freezer — the rapid temperature change and condensation can cause more harm than the heat did. Patience is the safest approach.
Beat the Heat This Summer
Heat and Battery Health
It's worth singling out batteries, because heat does them lasting harm. Every hot day a battery endures shortens its overall lifespan a little, which is why phones and laptops used through hot summers often need a battery replacement sooner than those kept cool. Keeping devices out of the heat isn't just about avoiding today's slowdown — it's about protecting the battery's health for years to come. If your battery already isn't what it was, the summer heat will make that all the more obvious.
