How to Backup Important Data before Clearing the Cache

The reset will erase all the data on your iPhone, and if you don't have a backup, you can't recover the data without using data recovery tools. So we remind you to make a backup of your iPhone data before resetting it.

You can make a backup with iCloud or iTunes and then restore data from them after the reset. However, iCloud only has 5GB of free space, once you don't upgrade the space storage, the data on your iPhone can't be backed up. When connecting iPhone with iTunes, iTunes may not recognize iPhone, resulting in data can't be recovered.

For these two reasons, we recommend that you use a third-party iPhone data backup software to back up the data on your iPhone, like FoneTool. It is a professional iPhone data backup application with a very simple operation and a clean and elegant interface, so if you are an IT novice, you can easily get started.

FoneTool supports a variety of file backups and does not require you to sign in to your Apple ID to back up your data, and will not overwrite the original data on your iPhone, ensuring the safety of your iPhone's historical data. It has multiple backup methods (full backup, partial backup, etc.), you can back up your data to your computer or to another Apple device. How to use FoneTool to backup iPhone data? Here are the steps to transfer data from iPhone to computer as backup.
