I. Why downgrade the iOS system of the iPhone?

Apple routinely issues updates for its operating system, strongly recommending users to update their iPhones to the most recent version. These updates aim to resolve bugs found in prior versions, introduce new features, and improve security, as older versions may become susceptible to hacking over time. However, users with older iPhone models often face challenges post-update, such as increased battery drain and system crashes. This highlights potential issues with new software compatibility and performance on legacy hardware.

Apple’s latest system updates are generally tailored for newer models. Attempting to upgrade an older device could be limited by its hardware capabilities, potentially unable to improve performance and may result in multiple issues.

If you want to keep your old iPhone on hand for a few more years, downgrading the iOS system to the appropriate version and turning off the automatic update system is a good way.

II. Preparation before iOS system downgrade: do a good job in mobile phone backup

Mobile phones, an integral part of our daily routine, hold a plethora of personal data such as photos, videos, contacts, text messages, apps, and call records. To safeguard against potential data loss, it’s crucial to perform a backup using either iCloud or iTunes prior to attempting an iOS system downgrade.

Kind tips:
