From (actual available maximum power/original designed maximum power * 100%), the approximate situation of battery loss can be calculated: 1046/ 1430≈72%, and the battery loss of this iPhone is already very light! In this case, the iPhone is prone to fast power consumption and "power jump (battery power suddenly drops a lot or is turned off directly)". If the calculation results show that the loss is too serious, then go back to the Apple store to experience the battery replacement service during the warranty period!
