IPhone 5s won't turn on

I've tried resetting my phone and I've tried leaving it to charge over night, then trying to reset it in the morning, but nothing is working. Should I take it in to get fixed? Or is there something I can do? I've tried the hair dryer method, I've tried plugging it in to a computer and I've tried resetting it.

Try holding power and home button

Reset it

Try taking the battery out and putting it back in and if that doesn't work you should go get it fixed.

OF course, go and fix it, looks like it's a battery problem, but if you can't switch on, what else you can do?

May as well take it to an Apple Store at this point.
