Is there a 555 IC timer in an iphone?
I'm doing a presentation on the 555 IC next week and need to show examples where the chip is used. When i press the home button and the screen lights up for a set amount of time, is that using a monostable 555 timer?
No. 555 timers would be used in simple electronic circuits. An electric toaster for example.
A 555 Timer IC is a very simple circuit that is required by very basic small electronic devices. The iPhone has an Apple A6 chip that does it all for the iPhone. No need for the useless 555 IC.

- Why does my iphone say no sim when there's a brand new one in there?

- Why does my iPhone 4 say there are headphones in when there isn't? I dropped the top of my iphone in water about an hour ago… And it is indicating water damage in the water damage indicator in the headphone jack. But, the only thing that seems to be wrong with it is that it says there's headphones in when there isn't. Is there anything that I can do to fix this? I have tried plugging in and unplugging headphones several times.
