TikTok videos are now telling users to put their iPhone into a fridge when it gets hot, a trend that has led to a surge of damaged devices in the UK. The advice is dangerous: condensation can form on internal components and thermal shock can harm the lithium battery. Apple’s own guidance is to let the phone cool naturally in a shaded area—never inside a car or a fridge, as even a glove box can reach dangerous temperatures.

Repair shops report a noticeable increase in failure cases linked to this misguided tip, especially during the recent heatwave that has pushed temperatures to record highs. The result? More batteries that may catch fire or fail outright.

If you’re dealing with an overheated phone, follow Apple’s recommendation: place it in a cool, dry spot and avoid drastic temperature changes. This simple step can prevent the condensation and thermal shock that put your device at risk.

The trend highlights how viral content can spread harmful misinformation, underscoring the importance of checking manufacturer advice before following online tips.
