As Minho said,you need a battery. The battery communicates with the iPhone as well. You can theoretically have it plugged in with a battery,then take out the battery,and it may stay on. But to power on,it needs the battery. for a battery to be that low,it seems it may have gone bad. Again,for the charging voltage to be present,the battery should communicate with the phone telling it that it’s there and needs to be charged. Also, a very low battery voltage could be a sign of a short. But with how old it is,I’d assume it’s likely the battery. Let us know if it worked out for you! For for the future,and amp Meyer is very useful. It reads the current flowing though it to the phone,and the voltage of the charger. It’s a usb plug that plugs into the charger on one side,and you plug the lightning cable in the other. Then it will tell you if the phone is pulling .6 amps or something,or if it’s 0.
