Many iPhone users have noticed that after updating to iOS 26, the System Data (also shown as “iOS” or “Other Data”) has ballooned in size. Some users report it jumping from 10 GB on iOS 18 to 30–45 GB on iOS 26 — sometimes larger than the operating system itself.
This can make a 64 GB or 128 GB iPhone nearly unusable, even if you’ve deleted apps, photos, and videos. Fortunately, there’s a community-tested workaround that can free up several gigabytes of System Data instantly.
Step-by-Step Fix

Check your storage - 
ورتګ Settings > General > iPhone Storage and note how much space System / iOS Data is using. 
 
-

بندول په اتوماتيک ډول تنظیم کړئ. 
- 
Manually set the date to today’s date but 3 years in the future (د مثال لپارهample, if today is September 25, 2025, set it to September 25, 2028).

Power the phone off completely. 
- 
بيرته يې وتړئ. 
 
- 
- 
Check storage again -

System Data should shrink — many users report recovering 5–10 GB immediately. 
 
- 
- 
Reset date & time - 
بیرته لاړ شه Settings > General > Date & Time. 
- 
وګرځي په اتوماتيک ډول تنظیم کړئ بیرته

Why Does This Work?
Apple hasn’t explained the cause, but evidence suggests System Data is inflated by:
- 
Caches that don’t auto-purge, 
- 
ننوتل files that continue growing, or 
- 
A bug in iOS 26’s storage reporting. 
By shifting the system clock forward, iOS forces expiration of cached data and temporary logs, then cleans them up during reboot.
اضافي لارښوونې
- 
Repeat when needed: If System Data grows again after weeks or months, you can repeat the trick. 
- 
Backup regularly: Storage issues can sometimes corrupt data. iCloud or iTunes backups help prevent loss. 
- 
Last resort: A full restore via Finder or iTunes usually resets System Data, but it’s time-consuming compared to the quick date-reset fix.
