yes i changed the battery, yes i inspected the battery connector, no signs of water damage
i have a 6s that will be fully charged or near fully charged, then it just dies and acts as if the battery has no charge at all
ive changed the battery, it doesnt help. the connector looks flawless, anyone know what ic causes this, or a high % solution to this issue

it stays on when connected to usb or power supply. the battery charges, but does so slowly at this point.

but it didnt slow charge beforehand

Use your brain. How does tristar fail? Does it fail because someone drops the phone? Or does it fail because of electrical damage from unprotected charger voltage. Now tell me why "reflowing tristar" is a dumb thing to do here.
