When the machine leaves the factory, your machine represents entering the market circulation link. But machines sometimes make mistakes. For example, "jump insurance" is one of the typical ways for Apple to make mistakes. When you choose to activate your mobile phone, Apple will officially receive your machine activation information and start calculating your warranty period. However, if there is something wrong with the server, your mobile phone will activate the warranty period by default when activating the serial number.
Then, if your Apple phone crashes, you don't have to worry too much. Under normal circumstances, after your machine is activated, the system will accurately adjust the warranty period of your mobile phone again after 72 hours. If you find that your machine activation period information does not match, the system will automatically modify your warranty period. If after 72 hours, your machine has not returned to the normal warranty period, in fact, you don't have to worry too much.
