If you have a Mac, connect it to one of the USB ports and run Coconut Battery application on it to see the status of the battery. https://www.coconut-flavour.com/coconutb… If it needs replacing, here’s how to do it: iPhone 6 Plus Battery Replacement
if a replacement battery doesn’t fix it then it sounds to be the charging circuit.
