I ordered a Iphone se about a month ago because my iphone 7 has audio ic issues and I cannot afford much. I also wanted a smaller phone. It arrived with`a battery capacity of 64% and i had another with 91% capacity. I blew up one and broke the other. I needed to get some info off my phone so i made a makeshift battery which i noticed the iphone started doing this. see picture 1. So i managed to scrape up enough money to get 2 batteries because i had a spare iphone that has touch ic issues. It also came up with the restart problem. Picture 2 is the brand of the pair of batteries that I bought. I will update soon but im posting this at the moment I noticed the problem
Not really sure what you are trying to do here but I only see a positive and negative circuit. If you haven’t got a gas gauge circuit the phone will turn off than on as it has no battery info.
fixed it, for some reason the phone wasn’t recognizing the battery after removing it and replacing it with the other one it recognized it. Both batteries work now
