Clear Up Storage on iPhone is easiest when you use the current iPhone settings or built-in Apple tools instead of older menu paths. The exact labels can vary slightly by iOS version, but the workflow below focuses on the current method and avoids steps that can erase or overwrite data unless that is the goal.
- Open Settings.
- Tap General, then tap iPhone Storage.
- Wait for the storage chart and app list to finish calculating.
- Review Apple’s recommendations and the largest apps first.
- Delete downloads or apps you no longer need, or use Offload App when you want to keep an app’s documents and data.
Photos, Messages attachments, downloaded media, and large apps are often better cleanup targets than trying to remove System Data manually.
