Trouble with new battery installment
I bought a new battery and installed it, but my iPhone 4s screen will not come on; however, it does charge and the charge signal shows. I am not sure what the problem is because just weeks earlier, I conducted the same repair with another iPhone 4s that I had it works just fine. I need to get the most recently repaired phone to work because it is my main phone. Do you think I bought the wrong battery or something else going on?
