Charging
yesterday, i tried to charge my iphone 12 promax even though the battery was not low and my phone tripped off. i tried to power it on for several minutes to no avail. i later plugged it for about 5 minutes and then it came on. when my battery was very low, i tried to charge it and it shows it is charging but is still on 1% for over 8 hours. what is wrong with my iphone?
iPhone 12 Pro Max, iOS 15
