Over time, batteries tend to lose their capacity, in this regard, the use of smartphones with non -tax batteries add excess headache for users. However, Apple customers will no longer have to worry about this problem. According to the updated conditions of the AppleCare+program, the owners of portable devices based on iOS can change batteries when their capacity falls below 80% of the original volume. As for the MAC computers with the AppleCare service plan, for them the threshold will become 50% of the original capacity. Recall that earlier, to replace the battery in the iOS device, Apple accepted only those devices whose resource fell half. As for the batteries for computers, they were subject to replacement and only if they found a production defect in them.
