On an iPhone, Go to Settings > General > iPhone Storage Tap it to review a list of files, including older ones that you might be able to do without. Some Android phones have a “Free up space” button at the top of the main Storage screen. If you want to keep the app but reset it to a brand-new state, you can tap Storage > Clear data.

Or under “Apps,” tap the app’s name and then Uninstall to remove it from your phone. For example, under “Audio,” long-press on one or more files and tap Delete.

If you drill down into the category, you can delete individual files or data.
