iPhone Storage Checker
Upload your screenshots of Settings › General › iPhone Storage. The AI scanner reviews your storage breakdown, calculates safe recoverable gigabytes, and provides an itemized data-safety plan.
iPhone Storage Checker
Upload your iPhone Storage screenshots to let AI review your storage, calculate recoverable gigabytes, and see a safe deletion plan.
Go to Settings › General › iPhone Storage on your device.
Take screenshots of your storage bar and apps (scroll down and take 1 to 4 screenshots if you have many apps).
Select 1 to 5 screenshots from your photo library (or drag and drop images here)
100% In-Browser Privacy: Your screenshots are analyzed directly on your device using on-device optical AI. Zero images are uploaded to any external server.

How the iPhone Storage Troubleshooter Works
Rather than asking you to manually estimate gigabytes across dozens of apps, this tool analyzes actual screenshots of your Apple iOS Settings screen to provide itemized, technically accurate deletion guidance.
On-Device Optical Recognition
Your screenshots are parsed locally in your browser using client-side WebAssembly optical character recognition (OCR). The engine identifies capacity headers and app sizes.
Multi-Page Deduplication
Because iOS storage spans 3 to 4 scrolled pages, you can upload multiple images. The engine automatically merges items and removes overlapping apps that appear across multiple pages.
Rule-Based Safety Audit
Applies official Apple iOS guidelines to evaluate each item, distinguishing between safe cache purges, offload options, fixed OS partitions, and actions that require cloud sync.
What to Prepare Before Scanning
For the most accurate diagnostic scan, capture complete screenshots from your iPhone following these 4 quick steps:
Open Settings › General › iPhone Storage.
Wait 5–10 seconds until the top segmented storage bar stops spinning and numbers finalize.
Take screenshots as you scroll down: Page 1 (Header/Photos), Page 2 (Social apps), Page 3 (Chat media), Page 4 (System Data at the very bottom).
Tap the upload button above to select all your screenshots at once.
Privacy Policy: 100% On-Device Processing
Your screenshots never leave your phone or computer. AskTechAdvisor executes all image scanning, text parsing, and character recognition entirely within your local browser memory using client-side WebAssembly technology.
- No image files are uploaded to any external server or API.
- No personal data, device identifiers, or app names are saved to a remote database.
- Closing or refreshing this browser tab instantly clears all uploaded preview thumbnails from memory.
Technical Limitations & Diagnostic Disclaimers
Independent Diagnostic Utility: This tool is an educational diagnostic calculator developed by AskTechAdvisor. It is not affiliated with, authorized by, or endorsed by Apple Inc. All Apple trademarks, Settings paths, and icons belong to their respective owners.
Theoretical Space Projections: All recoverable space figures (e.g. “~80 GB potential”) are calculated diagnostic estimates based on typical cache sizes and thumbnail compression heuristics. They are not guaranteed results.
iCloud Storage Dependency: Recommendations involving “Optimize iPhone Storage” require an active iCloud Photos sync and sufficient cloud capacity (such as an iCloud+ subscription if your library exceeds 5GB). Furthermore, iOS compresses local photos dynamically in the background when disk space is constrained; it does not instantly delete files upon toggling.
Variable System Data Results: System Data contains both purgeable temporary files and critical on-device databases. Connecting to a computer via USB triggers an internal iOS maintenance sweep, but the amount of reclaimed space varies significantly depending on whether iOS classifies cached data as purgeable.

Frequently Asked Storage Questions
Will "Optimize iPhone Storage" delete my original photos?
No! When enabled, iOS keeps lightweight display thumbnails on your phone while preserving full-resolution originals safely in your iCloud Photo Library. However, you must have sufficient iCloud storage space (an iCloud+ plan if your library exceeds 5GB). Space is reclaimed dynamically over time as iOS needs memory—not instantaneously.
What happens if I manually tap "Delete" on a photo with iCloud Photos turned on?
WARNING: If iCloud Photos is turned on, manually deleting a photo in the Photos app deletes it across ALL your synced Apple devices (iPad, Mac, and iCloud.com). Do NOT manually delete photos thinking they stay in iCloud! Keep photos in your library and let the automated "Optimize Storage" toggle manage compression.
What is the exact difference between "Offload App" and "Delete App"?
Apple explains that offloading frees up storage used by the app binary while preserving its documents and data. Reinstalling restores your data, provided the app is still available in the App Store. Deleting an app permanently erases the app along with all its local documents and data.
Why doesn't connecting to a computer always reduce System Data?
System Data includes active system databases, Siri voice packs, and caches. Connecting to a computer triggers iOS's internal cache sweep, but iOS only purges temporary caches that it classifies as purgeable. If your System Data consists of active OS logs or pending updates, minimal space may change.
Why does an iPhone freeze when free storage drops below 2 GB?
When free storage falls under 2GB, iOS has no room for virtual memory swap or app runtime sandboxes, leading to interface lag, keyboard stutter, and app crashes.
