What if my iphone is off and won't turn on how do I do this? it won't charge, turn on, connect to computer or anything

My iPhone 5 was working perfectly, I changed the passcode one night when I was drunk and couldn't remember it at all. I tried guessing it to whole time until it said iPhone is disabled please connect to itunes. When I go to connect the computer won't pick it up, will say the usb device can not be reconized. I have tried different cords, different computers and everything. So after a while my iPhone went flat and now it won't turn on, reset, charge or anything. Totally Black. I have tried drying it out. Resetting it everything possible. Any help would be greatly appreciated. As it has been three days with out it. In a remote area with no where to get it fixed for a long time. Please help
