Under Your Pillow or in Bed
You shouldn’t be taking your iPhone into bed with you. For one, the blue light from its screen can actually affect melatonin levels and interfere with your sleep. That’s true as notifications come rolling in through the night, too.
But it’s also important because smothering an iPhone can cause it to overheat. This becomes much more of a problem if your device is plugged into a charger and in bed with you.
Not only can this damage your battery, as we’ve covered in a previous slide, but it could also be dangerous. Although iPhones aren’t especially prone to catching fire or electrocuting you, there’s a chance that those things can happen to any device with a lithium-ion battery. It’s better not to chance it.
