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?

If you have a Mac compter you can use you can connect iphone to the comuter and use coconut battery. This Mac app will give you information about your battery. Best to have your phone fully charged if you can do that. It will work though without that constraint. I used it and it showed me that even though phone was fully charged it only had about 50% charge stored. My battery was dying.
Based on your graphics though it appears your cable or charger is not adequate for your phone. I'd check the battery first. If battery is ok, you might try a different cable and see how that works.
