Apple logo keeps flashing
Originally, battery would not charge (flashing logo) on Iphone 6s. Replaced the battery and it was charging.. it worked. Three days later and the logo starting flashing once again and will not charge? The new battery is dead.. What could be killing the battery? When I plugged into USB port on PC it said "power surge".. I guess meaning not enough power to charge device.
iPhone 6s, iOS 13
