That viral trick of cooling an overheating phone in the fridge could do more harm than good, with experts warning it may cause permanent internal damage.
Your smartphone may be feeling the heat this summer—but experts say the fridge is the last place it belongs. Repair technicians, Apple, Samsung, and other industry experts are warning users to avoid the viral cooling hack, saying sudden temperature changes can create condensation inside the device, leading to corrosion, short circuits, and costly repairs. Sometimes, the smartest solution is simply letting your phone cool down naturally.

Feeling sorry for your overheating smartphone? Whatever you do, don’t reward it with a trip to the fridge.
Every summer, social media revives the same viral “life hack”: If your phone gets too hot, pop it into the refrigerator for a few minutes. It sounds clever—until your phone ends up needing an expensive repair instead of a cool-down.
According to a BBC report, repair technicians and smartphone manufacturers all agree on one thing: your fridge is for leftovers, not smartphones.
Why your fridge isn’t your phone’s best friend
Jamie Farnell, who runs Shropshire Phone Repairs in the UK, says many customers arrived at his shop after trying the refrigerator trick during the recent heatwave.
The problem isn’t the cold itself—it’s the sudden change in temperature.
When a hot phone enters a cold, humid environment, condensation can form inside the device. That hidden moisture can reach sensitive components like the charging port, display, motherboard, and battery connectors, potentially causing corrosion, short circuits, or permanent damage.
In other words, your phone may survive the heatwave but not the fridge.
Another internet myth refuses to die
Farnell also poured cold water on another long-running internet “hack”—placing a wet phone in a bowl of rice.
According to repair experts, that trick is just as unreliable as refrigerating an overheating device.
His warning comes after a swollen lithium battery inside an iPad reportedly caught fire during June’s heatwave, highlighting how excessive heat can seriously affect batteries.
Apple and Samsung agree
Fortunately, your smartphone is smarter than many internet hacks.
Both Apple and Samsung say their devices are designed to protect themselves when temperatures rise.
An overheating phone may automatically dim its display, slow charging, reduce performance, or temporarily disable certain features until it cools down.
Rather than reaching for the refrigerator, both companies recommend moving the device into the shade, unplugging it from charging, removing thick protective cases, closing demanding apps, and simply letting it cool naturally.
Here’s what you should do instead
If your phone starts feeling like a pocket-sized toaster:
- Move it out of direct sunlight.
- Stop charging it.
- Close heavy apps and games.
- Remove bulky phone cases.
- Lower screen brightness.
- Let it rest in a cool, shaded place with good airflow.
Most importantly—be patient.
The coolest solution? Do nothing.
Modern smartphones already have sophisticated thermal management systems that know when to slow things down before permanent damage occurs.
That temporary warning message might be annoying, but it’s far cheaper than replacing a water-damaged motherboard because you thought your phone deserved a quick chill next to yesterday’s cheesecake.
So this summer, keep the ice cream in the freezer…
…and keep your smartphone out of it.
