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.

Net connection issue with my iphone?

I have a broadband connection in my home with D Link Dir 816 Wi-Fi router. The problem i'm facing is that when i browse on my laptop with windows 10 i don't face any issue but when i use my iphone on the same network the internet connectivity drops after some time. Then after some more time ( typically after 30-45 minutes) it again has net connection on my iphone. I'm totally confused about this issue. I also have tried with different router of tp-link.
