My phone is not charging properly, it’s starts charging and stops in between or it doesn’t get charged at all. I don’t use my phone while charging also, I’ve changed my charging cable , adapter and plug in points. So please do the needful.

If you already tried (to no avail) ALL the steps provided in this support article:--> If your iPhone or iPod touch won't charge , since your device is still covered by warranty, I suggest that you make an appointment (*) and have your device + charger + cable inspected at an Apple Store or AASP (Apple Authorized Service Provider) among this list:--> https://locate.apple.com/choose-country-region . After checking it out, they'll give you all the available options.

Regards

Giulio
