iPhone 5S won't charge, though showing charging symbol - LB damaged?
I've got the following problem with my three year old iPhone 5S, which I'd actually intended to use for at least two more years:
As the original battery was getting worse and worse, a few days ago I decided to replace it. I therefore ordered a new one, opened the phone for the very first time and, unfortunately, got one or more of the display ribbon cables to break, so the screen wouldn't work anymore. I bought a new one, installed it, got it to work, but, unfortunately, had then to discover that the battery wouldn't charge, although iOS itself showed it being in charging mode. I removed the new battery, put in the old one, tried to charge, and it did - at least three percent, because I just wanted to make sure it was the battery not working properly and not something else. I then replaced the original battery again with the new one, just to see, if it possibly, "magically" would work that time. It did not, so I put in the old one again, but this time I had to find out the old battery wouldn't charge anymore either.
Searching the internet for the reason it wouldn't charge, I found out I might have torn away the inductor FL11 when repeatedly removing and putting in the batteries. On the other hand, in a thread I read the iPhone would restart permanently if FL11 really would have been removed. That's not the case with my iPhone - the phone is usable as long as the battery in use has enough power; it doesn't charge - although, again, showing it charging -, but it also empties comparatively slowly. In addition, I can assume that power is reaching the phone, as the app "Battery Life" shows the exact same amount(s) of power coming through depending on the power supply and adapter as it does on an iPhone 6 I'm using at the moment.
I tried to find out more about that FL11-"thing", but couldn't even find its proper location above the battery port on a schematic diagram I neither did find. What I found though is that apparently two "pins" really are missing above the port - whereas photos of intact logic boards show a total of 14 units, mine appears to have only 12, as can be seen on the attached two photos.
My question thus is, whether those two missing units are the reason the phone won't charge, or whether instead the first battery was just a defective one from the beginning, and the original one became defective in the meantime. I ordered a new battery and will see if there will be any change, but, assumed there is a "deeper" hardware problem, it wouldn't be something I could fix without further ado, would it?
I hope somebody can tell me what I'm dealing with. Thanks in advance.
Edit: That's by the way what iBackupBot shows:
Shouldn't the "true" value regarding "GasGaugeCapability" mean that there isn't an issue with the logic board not being able to conduct current into the battery in general?
Is this a good question?
