So I have an iPhone SE and because they are old mine needed a battery replacement it went well all fine until I left it to charge. It wouldn’t charge but it would turn on but after a few minutes of use, it would restart so my first instinct was to replace the charge port but that did not resolve the issue I also tried to put the old battery in but I am having the same problems I think it might be the tristar chip but I am not sure so any help would be great
I think when you disconnect the battery connector you knock off a small component, take a magnifier and look around the battery connector on the logic board.
