I have an iPhone 6. It's (unfortunately but unavoidably) had repairs at a third-party repair shop for a new battery, and later a new USB connector - I think the contacts finally wore out, I use it a lot.
Now, suddenly, my phone is complaining about my cable, which I'm fairly sure is an authentic Apple cable, and failing to charge my phone. I can still transfer photos and use the hotspot, but even though the "lightning bolt" appears next to the battery icon, the % charge value is going down, rather than up, and rather fast!
Before resorting to another trip to the third-party repair place, is there anything I can try, or check, to see if I can get it to start charging again?
