How to free space in iPhone

Hi Aliyu,

Read this document to learn how to optimize the storage on a device --> How to check the storage on your iPhone and iPad - Apple Support

- "If your device is low on storage, it automatically frees up space while installing an app, updating iOS or iPadOS, downloading music, recording videos, and more.

To make more storage available, your device can remove some of your items, like streamed music and videos, files in iCloud Drive, and parts of apps that aren't needed. It also removes temporary files and clears the cache on your device. But your device only removes items that can be downloaded again or that aren't needed anymore."

If you find this involves upgrading iCloud storage to meet your needs but you do not wish to do that then the alternative is to delete items from your device (perhaps after downloading to a computer if they can be downloaded; e.g., Transfer photos and videos from your iPhone or iPad to your Mac or PC - Apple Support).
