How to Protect Your Phone from Overheating During Summer

December 29, 2025

Summer is the season for beach days, holidays, road trips—and unfortunately, overheated phones. High temperatures can strain your device, shorten battery life, and even cause permanent damage to internal components. As smartphones become more powerful, they also generate more heat, making them especially vulnerable during hot weather.

At Jazzfone, we help customers in Poole, Southampton, and surrounding areas keep their devices safe and running smoothly all year round. Here’s how to protect your phone from overheating during summer.

1. Keep Your Phone Out of Direct Sunlight

Leaving your phone exposed to the sun—on a table, car dashboard, or beach bag—can raise its temperature quickly.
Direct sunlight affects:

Tip: Store your phone in a shaded pocket or bag. If you’re outdoors, place it under a towel or inside a cool compartment.

2. Never Leave Your Phone in a Hot Car

Cars can heat up extremely fast, often reaching 50–60°C, even on mild days. This is enough to damage your phone’s battery and internal circuits.

Always take your phone with you when you leave the car, even if it’s just for a few minutes.

3. Avoid Heavy Usage in Hot Weather

Certain activities make your phone heat up faster:

These processes demand high CPU and battery usage.
If you’re outdoors on a hot day, try to limit these tasks or take regular breaks to let the device cool down.

4. Remove the Case When the Phone Feels Warm

Phone cases—especially thick or rugged ones—trap heat. If your device feels hot:

Never put your phone in the fridge or freezer—extreme temperature changes can cause condensation and water damage.

5. Charge Your Phone Safely

Charging naturally warms up your phone. Combined with summer heat, this can push temperatures to unsafe levels.
To charge safely:

Fast charging creates extra heat, so consider using standard slow charging on very hot days.

6. Close Background Apps and Reduce Strain

Too many apps running at once can cause unnecessary heat build-up.
To prevent this:

A lighter workload helps your device stay cool and efficient.

7. Use Airplane Mode When Needed

If your phone is overheating, switching to Airplane Mode reduces internal activity and helps it cool faster by cutting off radio signals.
