1 Not charging after battery replacement
I recently replaced my battery with one I bought from ifixit. It worked fine for a few weeks but suddenly it stopped charging. When I connect the charger it indicates that it charges but the battery does not charge at all. I opened the phone, disconnected and reconnected the battery and it seemed to be OK for the next weeks. Since yesterday I have the same problem again and the same trick did not do anything at all. Any ideas?
Update (11/23/2019)
Thank you all for your help. An update: I checked the charger port flex cable which seems fine. Then I disconnected the battery and when I plug the charger the phone shows the apple logo. The battery cable also seems to be OK. Maybe the battery itself is faulty? Should I ask for a replacement battery?
Ist dies eine gute Frage?

I have tried different cables with no luck. The port and flex cable also seem intact.

Does the battery look swollen?
You could have gotten a faulty battery.

Nope. The battery seems fine. Should I try connecting it without the battery? Just to see if the logo comes up? Or maybe the battery is faulty without being swollen? @Matt Black

When you put it on the charger, does it show anything on the screen? Can you power it on? Does the screen just stay black?
