Here is my orig. post With my 6s+ the battery went from 90% to 1% and restarted itself over and over, and then wouldn’t charge. I thought the battery was to blame so I replaced it. It worked good for a day and then its back to 1% and restarting. Now, its stuck in a boot loop were it will go between quickly flashing the backlight and flashing apple logo. Any ideas? Ive tried to restore but it doesn’t stay on long enough. Since then ive replaced the lightning connector, unplugged the camera, and tried to restore with screen unplugged. But my phone still bootloops. And, when i try to restore it it goes into bootloop before i can do anything. Can someone please help P.S. when i restore i get various errors, 4013, 2009, etc.
You’ll need to take the phone to a reputable repair shop that does board-level repairs on iPhones. I’m guessing along the lines of faulty Tristar (Charging chip) / PM IC (Power management chip).
I had the same issue but I changed the battery and Restored the Device to factory settings. its working now
