Iphone won't connect to itunes? - 6

I dropped my phone in a parkin lot from my brothers really up high truck when i was getting out and its been dropped probably plenty of times since then. But the screen has been cracked and i dropped on side walk here recently and i had completely reset it bc it was getting full & now it won't charge while its on or connect to itunes and by connecting it to itunes would be the only way because thats all its saying on the screen when i set it up back up…

any suggestions on what i should do?

Please Help. Thanks.

Added (1). Also my power button hasn't work since like the second day i got it, so it wouldnt do much holding the power button down or anything

I was going to suggest a hard reset, but for that you need to push the power button… Get a new phone?
