Apple has such a warranty, and users will obviously feel that the standby time is shortened. Assuming that it is charged once a day, when the loss reaches 80%, it may be charged twice a day. Apple's design requires that the normal battery loss frequency should be no less than 80% of the maximum battery capacity after 500 charge and discharge cycles. According to this requirement, the remaining 99% of the battery is normal after three months of use.
