iPhone spontaneously changes the volume in the settings

The iPhone 16 cannot spontaneously lower the ringer and alarm volume to the minimum without some form of trigger.

Here’s why:

1. Manual Settings Change – The most common reason for a volume drop is the user (or someone else handling the device) changing the settings manually.
   1. Settings > Sounds & Haptics allows users to set ringer and alert volumes.
   2. If "Change with Buttons" is enabled, the physical volume buttons can adjust the ringer/alarm volume.
2. Automation – Shortcuts or automations in the Shortcuts app can also alter the volume at specific times or under certain conditions.
3. Third-Party Apps – Some third-party apps with notification or sound management capabilities can affect volume settings, though iOS usually prevents them from directly modifying system sound settings without user action.

Conclusion:

If you’re experiencing unexplained volume drops, it is likely due to one of these triggers rather than a spontaneous system change.
