Yes, it happens over a variety of USB chargers and cables (both Apple and 3rd party for each).

Then something is wrong. It should be fine. My suggestion is to try doing a full os reinstall. Without data wipe. And see if it fixes it. If it doesn't you can try reinstalling it without data, and last resort. Try doing a DFU restore which will wipe but will fully restore it but yeah. If it's still like that. It might be a hardware issue then. Since if it is a problem. People would be reporting it everywhere
