You can also check the memory size of the mobile phone to judge the service life. Generally, the longer the mobile phone is used, the smaller the memory will be, and the appearance and configuration of the new mobile phone will be very different from that of the mobile phone used for several years. The average person can know how long the mobile phone has been used just by looking at its appearance. If you don't understand, you can ask at the roadside mobile phone repair shop.
