have an iPhone 6s which came in with no power, upon plugging it in it bootloops. Remove the cable and it dies. Under thermal cam the Charging Ic is what flashes but i dont have a reason to believe the charging ic is bad. Any help would be appreciated! Update (08/25/2021) on the DCPS it goes upto an AMP of current and then dies

it might be a battery problem since they are notorouis for having bad batteries and apple even has a replacement program for them I hope this information was helpful
