Chosen Solution
Because my iPhone has been used for four years (it was purchased right after the release) it’s battery was getting pretty bad. I decided to replace it, and bought a battery from Mobile Defenders with good ratings. I put it in, finished the repair, and turned the phone on. The phone worked good for a few minutes, but was at a very low battery percentage. I plugged it in, kept using it, and it got stuck in a bootloop. The bootloop wasn’t like most bootloops because it shows the home screen for a few minutes before restarting. We contacted Mobile Defenders and they sent a new battery which fixed nothing… Thank you, Michael
You have nudged or knocked of the component I have shown. This often happens during a battery replacement if you don’t know the components are there. This circuit supplies the battery info to the charging IC if it is not getting any information it will boot-loop.
Battery either doesn’t work or you’ve broken the pins on the battery connector
