iPhone users facing storage shortages can reclaim significant capacity by deleting and reinstalling applications, a method that has reportedly freed up 62GB of space on a 128GB device. This process addresses the “System Data” category, which Techritual 香港 reports can occupy nearly half of a 128GB model’s available storage.
System Data Files Vary Based on Usage and Activities
The “System Data” category, formerly known as “Other” in older iOS versions, functions as a collection of files required for iOS operation that fall outside the core operating system. This includes caches, logs, credentials, downloaded fonts, keyboard assets, and Siri voice data. Techritual 香港 notes that the size of this category varies based on user customization, application usage, and specific activities. While iOS attempts to perform automatic cleanup to maintain performance, the size can fluctuate wildly from a few gigabytes to dozens of gigabytes over time.
When storage reaches critical limits, the device may struggle to install updates or expand temporary files. This creates a technical bottleneck where the system cannot function optimally unless the user manually intervenes by deleting files or apps. Techritual 香港 suggests that a simple restart—powering off the device for approximately one minute before turning it back on—can occasionally prompt the system to shrink the System Data footprint by clearing certain caches and restarting background processes.
Reinstalling Apps to Reclaim 62GB of Space
A user on the social media platform Threads demonstrated a drastic method for clearing space by deleting all installed applications and then downloading them again. According to Chinatimes, this individual saw their used storage drop from 127GB to 64.78GB on a 128GB iPhone, effectively reclaiming 62GB. This approach works because many applications accumulate “fat” or large amounts of cached data that standard internal cleaning tools may fail to remove.

While effective, this method requires caution regarding data retention. Chinatimes reports that users concerned about losing chat histories in apps like LINE should back up their data and enable account migration settings before deletion. Some users have noted that while this clears space, the cached data may eventually return as apps are reused, and the initial re-downloading process may cause a temporary spike in mobile data usage.
Specialized Tools for Media and File Management
Beyond manual app management, several utility applications offer automated ways to manage the specific files that contribute to storage bloat. Users can utilize different tools depending on whether they need to target media or general file compression.

- PhotoSpaceSlim: Photo Cleaner: As reported by Newmobilelife, this utility allows users to analyze storage usage by timeframes, such as the last 30 days or the past year. It identifies and suggests the removal of old screenshots, large videos exceeding 100MB, screen recordings, and similar photos.
- Video Compressor Gold: According to ezone, this application provides batch processing for compressing videos and photos. It claims to reduce file sizes by 80% or more while attempting to keep visual degradation minimal. It also includes features to quickly identify large files within the device.
The following table summarizes the storage impact and management options discussed across various reports:
| Method/Tool | Primary Target | Reported Benefit/Result |
|---|---|---|
| App Deletion & Reinstall | Application Cache/Data | Reclaimed 62GB on a 128GB device (Chinatimes) |
| PhotoSpaceSlim | Screenshots & Large Videos | Categorized analysis by timeframes (Newmobilelife) |
| Video Compressor Gold | Video/Photo File Size | Reduces file size by 80% or more (ezone) |
| System Restart | System Caches | Potential reduction in System Data (Techritual 香港) |
The Economic Pressure of iPhone Storage Upgrades
The struggle with storage management is compounded by the high cost of hardware. Techritual 香港 highlights that Apple’s storage upgrades remain a significant profit driver, and the entry price for the iPhone Duo reaches as high as US$2,000. With memory prices rising, consumers face increasing difficulty balancing the growing size of modern applications and high-resolution files against a strict budget. This tension makes the ability to manage existing storage through software interventions a necessity for users on lower-capacity models.
Whether these software-based cleaning methods provide a permanent solution or merely a temporary reprieve remains an open question for users managing high-density data environments.
