iPhone 5 wont charge battery if fully dead or phone is off
i have had this happen on a iPhone 5 and a iPhone 5s now, the phone is completely dead and wont turn on. tried every cable and power source possibly imagined. the phone will not charge. after replacing the battery the phone turns on and charges fine, but if the phone gets turned off or if the battery dies the iPhone stops charging??????? i monitor this by using a volt meter attached to the USB cable that tells me amps and volts of what the device is pulling for power and charge. so basically in short if the phone has enough power in the battery to turn on and start charging then it works great, but if you turn it off or the battery can not power the phone to the o.s. then it does nothing. has any one seen anything like this? i have stripped the phone from its shell and tested with new batteries and dock connectors, with no effect, the only thing running on the board a screen, battery, and charge port.
