Is there any way that my smashed/dead iPhone 6 is salvageable?

I know there is probably no way, but my iPhone 6 was cracked after a heavy fall and now fails to turn on even after hours of charging. I really really need the data on the iPhone but unfortunately may have backed it up a long time ago. It's been a week and still nothing, I was wondering if there was any way of my Phone being repaired and have all the apps and data restored? I can't stress the importance of the data on my phone but expect disappointment and would probably have to replace the phone...
