My iPhone 5 won't accept charge
In December of 2014, I had to get a replacement iPhone because my other one didn't hold charge. Now this replacement is NOT ACCEPTING charge. I don't know how to reboot it considering my lock button also doesn't work. It only charges if I hold the cord a certain way and etc. I just need this phone to last until the newer one comes out in a few weeks. PLEASE HELP ME
iPhone 5, iOS 7.1.1
