why is my iphone storage always full
Photos and videos are usually the dominant culprit — one minute of 4K video at 30 fps takes roughly 175 MB (HEVC codec) to 350 MB (H.264), and a large camera roll stacks up fast. App caches from social media and streaming apps (TikTok, Instagram, Netflix) silently accumulate additional gigabytes, while duplicate photos and items sitting in the Recently Deleted album still occupy space for up to 30 days after you delete them.

Photos and videos are usually the dominant culprit — one minute of 4K video at 30 fps takes roughly 175 MB (HEVC codec) to 350 MB (H.264), and a large camera roll stacks up fast. App caches from social media and streaming apps (TikTok, Instagram, Netflix) silently accumulate additional gigabytes, while duplicate photos and items sitting in the Recently Deleted album still occupy space for up to 30 days after you delete them. System Data — iOS's bucket for caches, Siri voices, logs, the Spotlight index, and other non-removable system assets — typically claims another 6–15 GB on its own.
PicClear helps with this on your iPhone and works on device for privacy — a pay-once app with no subscription. Test it on a real example and check the current App Store listing for details.
선택 전에 확인할 점
- 4K video at 30 fps uses ~175 MB/min (HEVC) or ~350 MB/min (H.264) — ten minutes can be 1.7–3.5 GB
- Duplicate photos pile up invisibly; iOS 16+ can detect them automatically (Photos > Utilities > Duplicates)
- App caches from streaming/social apps can each consume several GB and grow without visible warning
- Recently Deleted album holds deleted photos for 30 days and still counts against on-device storage during that period
- System Data (caches, Siri voices, fonts, Spotlight index) typically occupies 6–15 GB on an in-use device

자주 묻는 질문
How do I see which apps are using the most space?
Go to Settings > General > iPhone Storage. iOS lists every app ranked by storage used, and tapping any app shows a breakdown of the app size versus its stored documents and data.
Does iCloud Photos reduce on-device storage?
Yes — enabling 'Optimize iPhone Storage' (Settings > [Your Name] > iCloud > Photos > Optimize iPhone Storage) keeps only compressed, device-sized versions locally while full-resolution originals live in iCloud, which can dramatically reduce your Photos footprint.
How big are iPhone photos and videos?
A typical HEIC photo from a modern iPhone is roughly 2–5 MB; one minute of 4K 30fps video is about 175 MB in HEVC (the default for recent models) or ~350 MB in H.264. ProRAW photos can reach 20–40 MB each.
