Photos and videos (usually 60%+ of storage)
Enable cloud sync (iCloud or Google Photos), then turn on 'Optimize Storage' (iOS) or 'Free Up Space' (Google Photos). Originals stay in the cloud; smaller copies stay on the phone.
Recovers 10–40GB on most phones in 30 minutes.
Apps you don't use
iPhone: Settings → General → iPhone Storage. Sorted by app size. Delete what you haven't opened in 6 months.
Android: Settings → Apps → sort by size. Same drill.
Downloads and cache
Files app → Downloads. Most are forgotten PDFs, images, or installers. Delete the lot.
Browser cache: Safari → Settings → Clear History. Chrome: Settings → Privacy → Clear browsing data. Recovers 1–3GB.
People also ask
Why doesn't iPhone storage 'add up' to my total?+
Hidden 'Other' or 'System' storage uses 5–10GB. A full restore (back up, wipe, restore) usually shrinks it.
WhatsApp media takes 8GB — can I delete some?+
Yes. WhatsApp → Settings → Storage and Data. Delete media from chats you don't need.
Should I buy more storage on iCloud / Google?+
Cheaper than buying a higher-storage phone. $1–3/month for 50GB is good value for most users.
