How to clear other system data on iPhone 14 pro - Showing 108GB of this data

Hi Ladd-14pro,

Thank you for posting in Apple Support Communities! Since noticing that the amount of system storage was high, has your iPhone been restarted? Restarting your device can help when we face unexpected issue such as this one.

To restart your iPhone:

1. Press and hold either volume button and the side button until the power off slider appears.

2. Drag the slider and wait about 30 seconds.

3. Press and hold the side button until the Apple logo appears to power it back on. Once back on, test to see if this continues.

Check out: Restart your iPhone - Apple Support

If this continues, you may want to reach out to Apple Support for further assistance. Depending on your region, you may be able to reach them here: Get Support.

Take Care!

You're welcome Ladd-14pro. We're glad we could help. Feel free to reach back out if you have any further questions or issues with an Apple device or service.

Have an excellent day!
