How to do a clean install of any version of iOS or iPad OS on iPhone and iPad

If your iPhone, iPad, or iPod touch is slowing down, a clean install of iOS or iPad OS may speed it up. Installing a new system software means that there are no third-party App Store apps, the configuration is broken, and the settings are broken. This can have a positive impact on performance. A clean installation can also fix problems that standard troubleshooting cannot solve.

There are several ways to do a clean install of iOS and iPad OS. The first method requires you to erase all content and settings using only your iPhone or iPad, and the second method requires you to reinstall the system software via your Mac or PC.

A clean install of iOS or iPad OS will erase your data, but you can always choose to pre-backup your files and settings. Then it’s up to you to start over or restore the backup and resume where you left off.

Erase all content and settings

iPhone and iPad have an integrated “Erase This iPhone / iPad” tool that allows you to quickly reset your device to factory defaults. It handles everything from creating backups of your data to iCloud, deactivating FindMy and ActivationLock, and erasing all bits of your personal data from your device.

The “Erase This iPhone / iPad” tool technically does not reinstall iOS or iPad OS, but this procedure restores the system software to a ready-to-use state from your iPhone or iPad. It’s also much faster and more convenient than performing a restore via a Mac or PC.

1. Open setting App from the home screen of your iPhone or iPad.

2. Select Universal >> >> Transfer or reset iPhone >> >> Erase all content and settings (IOS 15 / iPadOS 15 or later) or Universal >> >> reset >> >> Erase all content and settings (IOS13 / iOS14 / iPadOS 14 or earlier).
