First of all, congratulations on your new phone, as for how to tell if the phone is brand new?
Generally speaking, in the official online**, offline stores, such as Apple, Huawei, OPPO, vivo, Xiaomi, etc.**, or some third-party platforms, such as X East, X Cat self-operated platforms will be new machines, if you find that it is shoddy, sell new with the old, you can directly complain.
If you're still not sure, you can send itThe official after-sales service of the brandTesting, there is generally no charge during the warranty period.
Secondly, you can inspect the machine in person, before opening the seal, the first is to observe the packaging box, whether the plastic package is very regular and complete, there is no trace of unpacking, and then see whether the real machine accessories are complete, consistent with the official statement.
Then carefully observe the mobile phone to see if there are traces of human use, such as fingerprints, hair, dust, etc., just after unpacking, and then look at the bezel and lens for scratches, dust, etc. Observe whether the speaker is clean, the charging port is dusty, and so on.
After unpacking, check whether the package is three or five codes in one, check the maintenance time on the official website, and see if it is consistent with your activation time.

Then plug in the computer, Apple iPhone can use AISI, Hourglass software to check the usage, including the number of charges, battery cycles, activation time, etc. to make a comprehensive judgment, I hope it can help you.
