iOS forensic analysis is the forensic investigation of a device that runs on the iOS operating system, which is exclusively present in Apple products such as the iPod, iPhone, and iPad. It covers the instruments required as well as the types of information that can be gleaned from the device's study.
When data is erased from an Apple iPhone device, it is stored in the device's free space or the structure of a database file (mostly SQLite format), and it can be overwritten by new data entering onto the phone. Unfortunately, data that has been overwritten cannot be recovered.
Launch the Settings app after unlocking your iPhone or iPad. Select General.
Reset may be found at the bottom of the page.
Erase All Content and Settings is the last option.
If prompted, enter your passcode.
To wipe the iPhone and remove it from your account, enter your Apple ID password. Erase is pressed.
When you select Erase All Content and Settings, your device is fully erased, including any credit or debit cards you've added for Apple Pay, as well as any images, contacts, music, or apps. iCloud, iMessage, FaceTime, Game Center, and other services will also be disabled.
When thieves realise they can't use the stolen iPhone, they split it into numerous pieces and sell them for cash to shady repair companies or stores. These types of stores require numerous parts of the iPhone, such as the screen, in order to repair another person's broken iPhone at a low cost.
