Chosen Solution
Hi, I had an iPhone 5 without a screen lying around for quite some time and I finally decided to buy a new front display (complete assembley). But now I noticed the phone won’t start, I first tought the battery was completely drained as it was not charged for well over a year. But when I plug the charger in it doesn’t do anything, even when I let it charge for over an hour. But when I plug in the charger I hear a verry faint clicking noice near the battery connector. Also when I try to messure the voltage across the battery it gives me 0V Could somebody please help me with this?
I think you have to charge the battery first from outer source.While the battery is in complete sleep mode sometime charging with phone is in vain.So take out battery and charge the battery from direct source like dc power supply.
