Shared on a Twitter account run by Deputy Inspector Wilson Aramboles, the four frightful images show a damaged phone next to a scorched pillow and bedding.
“Don’t put your cellphone under a pillow when sleeping or when charging your device. Please share this tip and b safe!” reads the caption accompanying the post.
This fire risk is caused by the overheating that happens when some phones are charging.
“The batteries heat up, they could melt—in some cases, explode—and cause a fire,” explained a fire chief last year after a teenager’s phone set his bed alight.
“It is recommended that you leave these types of devices on a hard surface so the heat can dissipate.”
In 2014, a 13-year-old girl fell asleep while while her Samsung Galaxy S4 was charging under her pillow. Later woken up by the smell of something burning, her phone was “fried into an unrecognisable slab of plastic and melted components”.
