so far ive been trying to charge my battery outside of my phone without an external charger and the only good way ive found is very painful... basically what i do is use a cut usb cable and connect the red wire to the positive and the black to negative... but i have to hold it in place with my thumb and it burns me... bad. so please help. btw ive tried electrical tape but it wont stay in place. is there any way i could make a makeshift charger with a cut usb cable?
