Troubleshooting Common Issues in Checking Your Phone’s Manufacturing Date
When you are attempting to know how to date your phone manufacturing date and encounter some problems, you are not alone.

When that happens, you can either use a third-party application such as “Device Info” or look into the serial number in the settings menu.
In iPhones, newer decoding techniques used on the older models might not work on the newer iPhones with randomized serial numbers. When you cannot decode it, use the apps such as coconutBattery (Mac users) or look at the manufacture date of the battery under Settings Battery Health.
There is also the issue of wrong outcomes of unreliable IMEI checker sites. Never use unofficial brand tools or unreliable apps. In addition, in case your battery has been changed, the date of manufacturing of the battery might not correspond to the date of manufacturing of the phone.
