Will dust destroy my iPhone?

I've had an iPhone without a screen sitting in my drawer for a few months. I was meaning to purchase a new screen, but I just noticed it's covered in dust. Would the dust destroy the inside of my iPhone or at least specific components of it? What if I vacuumed the dust out?

Give it no thought

take it to one of those kiosks manned by the friendly Korean folk - theyll sort it for you

No, it won't get inside, it's just on the surface. Just wipe it off with a damp cloth.

If not removed, then yes. Your iPhone will suffer overheating and premature failure of its mainboard due to the dust acting as heat insulation. I would also strongly advise not using a vacuum to clean the iPhone internals since it can suck out the delicate pieces.

Never use a damp cloth or vacuum to clean PCB boards.

The dust just collects on outside surfaces and shouldn't have any impact on the iPhone working.

  • Why do people destroy iPhones on youtube? Not just iPhones, there are hundreds of videos of people destroying expensive gaming consoles, TVs and other mobile phones. Why would they do that?

  • What is a fun way to destroy my iPhone 5? - 2 I have microwaved, drilled, grilled, water tested, car ran over, hammered, and more with my iPhone 5. I get paid to do this on my "TechRax" youtube channel. My question is what can I do next that can awe my audience? Or what would something that would shock you? Just be realistic, not like throwing an iPhone against a wall. I was thinking of maybe a freeze test. Thanks. Deep fry it! That's it!
