Added (1). PS: It is a 5c iphone

What iPhone is it? If its older than a 5s then it's time to upgrade. If not then try to hook it up to a computer with itunes and get into recovery mode or dfu mode and try to update or worst case you may have to restore your phone to factory. Hope you have a backup.

Try holding the power and home button down to reset it. If it still doesn't come on contact Apple especially if it's fully charged.

It is broken get a new one

Not charged.
