My iPhone isn't charging

Have you tried a different official lighting charge cable just to rule out it ain't a faulty cable?

If your iPhone is still currently powered on I recommend doing full back up on iCloud to protect your data.

If you've tried two different official lighting cables (might be good idea to have close look at charging port for dirt/dust stuck in there that could be cleaned out).

If all else fails purchasing a wireless charger would allow you to charge/use the phone until you can get to Apple shop to investigate that issue for you (after COVID 19)
