My iphone 5s won't turn on?

Last night my phone was working just fine. it had only 1% left to i put it on the charger. When I woke up it was turned off, so i thought maybe it didn't charge my charger sometimes if moved, doesn't charge. but then when i put it on a different charger it wouldn't turn on. I left it to charge for a couple of hours and didn't have any results. I tried pressing the home/power button together and separately and still didn't get anything. I also tried connecting it to my itunes..nothing. What should I do?
