iphone XR not charging

Sorry to hear about your issue, have tried different official lighting cables to rule out it's not a faulty cable?

Also look closely at the port to see if it needs to be cleaned (I had this issue before with dust building up in my iPhone X port)

If no luck with that, it will be most likely be a faulty charge port / battery.

You could attempt to purchase a wireless charger to see if that will charge your iPhone XR (also it would prove the battery isn't faulty and it's a faulty charge port)

You might be able to replace the battery at your local apple store. https://support.apple.com/en-ae/iphone/repair/service/battery-power. In this website (official apple website) you can also check the prices if you scroll down. If you have apple care it is free. Look over the website and see if it helps. Hope this helped. :)

my iphone XR does not seem o charge well. looks like it has a loose contact and charger has to be put a certain way and often it stops charging. Using a wireless charging currently but that does not work while am gone since i dont have one in the car. The cable seems wobbly when connected. Is this a known issue and do you fix that?

Thanks
