Delete unused apps, offload photos to the cloud, clear browser cache, and remove downloaded podcasts/videos. iPhone: Settings → General → Storage shows the biggest offenders. Android: Settings → Storage → Free up space.

Follow-up questions

What's taking so much space?

Usually photos and videos, then messaging apps with years of cached media, then games.

Should I delete WhatsApp cache?

Yes — WhatsApp media alone can hit 20+ GB. Delete inside the app: Settings → Storage and Data → Manage Storage.

Does 'Optimize Photos' delete originals?

No — full-resolution copies stay in iCloud; only lower-res versions live on the device.

How much free space should I keep?

10–15% for smooth performance. Below that, apps crash and updates fail.
