Free up Discovery+ storage

Discovery+ stores episodes you save for offline viewing, plus a watch cache so the next episode starts quickly. My List stays on your account. Removing a download only deletes the file on this phone.

See how much space Discovery+ is using

iPhone

Open the iPhone Settings app.
Tap General > iPhone Storage.
Tap discovery+ or Discovery+.

Android

Open your phone Settings > Apps.
Tap discovery+.
Tap Storage or Storage and cache.

Discovery+ does not have a WhatsApp-style storage screen. Open Downloads to see titles on this phone.

Delete downloads

Open Discovery+ and tap Downloads (sometimes under your profile or My List).
Tap a title and remove the download.

Full seasons are the largest items. The show stays in My List and can be downloaded again later.

Change download settings

Open your profile and tap Settings.
Open Downloads if listed.
Set a lower download quality, and turn off cellular downloads if that toggle is shown.

Clear Discovery+ cache on Android

Open your phone Settings > Apps > discovery+.
Tap Storage or Storage and cache.
Tap Clear cache.

Do not tap Clear storage / Clear data unless you mean to reset Discovery+ on this phone. That signs you out and removes local downloads. My List stays on your account.

iPhone does not offer a separate Discovery+ cache button. Delete items under Downloads, or offload the app in iPhone Storage if the system total stays high.

Reinstall the app if storage is still high

If you already cleaned media and Discovery+ still looks huge, a fresh install can clear leftover cache and temp files that are hard to reach by hand.

Downloads will need to be re-downloaded after you sign in. Your account keeps My List and watch history.
Delete the app from your phone.
Restart your phone.
Install Discovery+ again from the App Store or Google Play.
Sign in and restore from backup if the app offers it.

This often frees a lot of space. You may need to download some media again after restore.

What to do next

After Discovery+ is lighter, check your photo library for duplicates and similar shots. That is what Dedupo is for.
