iphone SE charging issues

Hi folks,

Has anyone had issues with the iphone SE (iOS 10.2) not charging and then spontaneously shutting down and restarting over and again?

Have tried a hard reset, settings reset, different cables, checked the charging port, power source etc all to no avail.

Can't get itunes to recognise the phone either 😟

All just started suddenly today after 3 months since I purchased the phone brand new and have had no problems with it til now.

Any tips most welcome!
