To find out how old an iPhone is, there are two main steps:
- Identify the iPhone model by either looking at the back of the phone or going to Settings > General > About to find the model number.
- Find the release date of that iPhone model by searching online or using Apple's website.
Additionally, you can check the manufacturing year and month by looking at the iPhone's serial number in Settings > General > About. The fourth character of the serial number indicates the year it was made, and the fifth character can indicate the month. For instance:
- K or L means it was made in 2013
- M or N means 2014
- And so on through subsequent letters for later years.
Another way is to check the battery's first use date in the Settings under battery info, which gives a good estimate of when the iPhone was first activated, especially for newer models. If the user has the iPhone model or serial number, they can use those to pinpoint the age more precisely.
If specific information about the user's iPhone model or serial number is provided, the age can be determined more exactly.
