Hello, my iPhone 3G is stuck on the apple logo and then shuts off. It only turns on with a power cable and shuts off once i plug it out, I searched the internet to see if ot works without a battery but i didn’t find any answers. So if it isnt a hattery problem, I don’t know what is. Any help is appreciated.
Those are the classic symptoms of a bad battery. I linked a guide below: iPhone 3G Battery Replacement
