The red storage warning is annoying. Here are 5 ways that actually work — sorted by effectiveness.
On most iPhones, photos and videos eat 60–80% of used storage. If you've been using your iPhone for years, that's easily 100+ GB.
The clean fix: transfer photos to Mac (or an external drive) and remove them from iPhone. Important: not via iCloud sync, which deletes from Mac when you delete from iPhone — but a real transfer + local backup.
That's exactly what Rivr is for. Connect USB, pick "Top 100 by size", transfer, optionally auto-delete from iPhone. Often 30–50 GB freed in 10 minutes.
Settings → General → iPhone Storage. At the top is a colorful bar showing your biggest space consumers. Below: recommendations like "Review Large Attachments" or "Review Received Photos and Videos". A few taps often yield several GB.
WhatsApp is often #2 after Photos. Open WhatsApp → Settings → Storage and Data → Manage Storage. Sort by "Size", delete the largest chats (or just their videos). On older iPhones with active family chats this is often 5–15 GB.
Settings → App Store → Offload Unused Apps → enable. iOS will automatically remove apps you haven't opened for weeks while keeping their data. The icon stays with a small cloud. One tap re-downloads it.
Settings → Safari → Clear History and Website Data. Typically 0.5–2 GB. Same with Settings → iPhone Storage → "System" — if that's large, a restart or iOS update usually helps.
The first three steps give 80% of the impact. If you offload photos regularly (say, once per quarter), you'll never hit the "storage full" wall again.
