iPhone System Data Bug Eats Up to 150GB of Storage as Users Share Fixes

Summary
Reddit users reported iPhone and iPad storage losses above 100GB from iOS's System Data category, including cases of 100.62GB and 150.56GB disappearing into what they described as a long-running bug.
128GB devices appear especially exposed: one user showed 86.96GB consumed by System Data alone, swallowing 68% of total storage and leaving little room for apps, photos or downloads.
Backup-and-restore emerged as the most cited remedy, with users saying an iCloud or computer backup followed by a reset — or even a DFU restore — can clear runaway cache and reinstall a fresh copy of iOS.
Less drastic workarounds also helped some users, including enabling Offload Unused Apps, clearing browser and podcast caches, and deleting apps or games with large extra downloads.
The reports suggest the issue is not isolated to one app and has persisted for years, underscoring how fixed iPhone storage can magnify software-related space problems.
