My phone is not charging I wanna transfer my files but phone is dead

I'm gonna do the best I can to explain this. My phone is a Droid Maxx when it's connected to a charger it shows its charging right but then it doesn't charge after that battery charging screen turns off. To prove that it is doing it. I've attempted to charge it on the computer. My computer kept making notifications sounds to detect, and undetect the usb on my computer. I wanna be able to transfer all my stuff on the phone but it's at 0%.

Is there anyway I can transfer all my items to the computer if my phone battery is dead.
