My iPhone 5s has been dead for over a year is there any way to turn it back on?

I've tried pressing all the buttons down for a couple seconds and the hairdryer trick, but they didn't work. I want to use my iPhone 5s for storing pictures and music because I'm already running out of space on my iPhone 6s. I don't want to spend money going to the Apple Store to get it fixed. Is there anything I can do to turn it back on? Nothing comes up it's just a black screen.

Did you charge it
has it had water damage
and if you wanna store photos and **** then get google photos
