Some update files have complicated formats or larger file sizes, allowing you to use more of your iPhone's internal capacity. If your smartphone still has a lot of space, this shouldn't be an issue. However, if you often download complicated programs and multimedia files, your available memory is likely insufficient. When this occurs, performance issues such as frequent crashes and sluggishness arise. This means you'll need to manage or free up some internal storage space on your phone. All unneeded stuff, such as outdated messages, programs, and files that are no longer helpful, can be deleted. There are a few more things you may do to free up memory space:

• Press and hold the Home button twice fast on your iPhone 7 to delete background applications. A list of your recently used applications will appear if you do so. After that, swipe up to clear each app's preview.
• Remove any programs or data that you don't need. It's time to get rid of any outdated or unneeded items. So start sifting through your iPhone's mail inbox, photo galleries, and other media folders to find and delete any unneeded data.
• Tap and hold any app icon on the Home screen to uninstall any unneeded applications. Tap the X in the corner of the app you wish to delete or uninstall when the icons begin to vibrate. To complete the process, press Delete.
