If you spend any time on TikTok, you have probably seen videos telling you to toss an overheating iPhone into the refrigerator to cool it down fast. The logic seems to make perfect sense when the summer heat is breaking records. You might be tempted to try it out when that high temperature warning pops up on your screen. You should ignore this viral advice entirely because it will ruin your device and cost you a lot of money in repairs.
Dropping the temperature too fast causes permanent internal moisture damage
Taking a phone that is running above 110 degrees and dropping it into a cold environment is a recipe for disaster. This drastic shift causes thermal shock. The different materials inside the phone shrink at different speeds when exposed to sudden cold. This uneven shrinking puts massive stress on the internal circuits, the screen, and the camera hardware.

Beyond thermal shock, the cold air introduces a severe risk of condensation. Your phone is not completely sealed against the air. If you put a cold soda can outside on a warm day, water droplets form on the metal. The same thing happens inside your phone when you put it in the fridge. The normal air inside the device turns into liquid water.
This moisture collects on sensitive electronics and damages the battery over time. In a worst-case scenario, a ruined battery can even catch fire.
Move your hot device to a shaded room to cool down
Modern phones have built-in safety features designed by Apple to protect their internal parts from heat. If you see a high temperature warning on your screen, the system is already working to prevent hardware damage. The phone will shut down non-essential functions to keep itself safe.
You do not need to intervene with extreme cold. Instead, just unplug the device if it is attached to a charger. Take off the case to help the trapped heat escape. Move the phone out of direct sunlight and leave it alone in a cool room. Giving it a few hours to rest will bring the internal temperature back down safely.
Avoiding the heat in the first place is always the smartest move. Try not to leave any electronics in a parked car during the summer. A car interior can reach dangerous temperatures in just a few minutes. Keep your phone in your pocket or a bag when walking around outdoors.
