The slow charging time of the iPhone 12 depends on the charger used and charging conditions. Using the original 5W charger, the iPhone 12 takes about three hours to charge from 0% to 100%. If you use a charger that supports fast charging, such as a 20W charger, the charging time can be reduced to about 1.5 hours. During the charging process, if the phone is used, or the phone is in a high temperature environment, the charging speed may be slow.
