Customize iPhone for motion sensitivities
If you have sensitivity to motion effects or screen movement on your iPhone, you can stop or reduce the movement of some screen elements, such as:
Parallax effect of wallpaper, apps, and alerts
Screen transitions
Siri animations
Typing autocompletion
Animated effects in Messages
Go to Settings
> Accessibility > Motion.
Turn on or off any of the following controls:
Reduce Motion: Reduces the motion of the user interface, including the parallax effect of icons.
Auto-Play Message Effects: Allows the Messages app to automatically play full-screen effects. If you turn this setting off, you can still manually play effects by tapping Replay below the message bubble.
Auto-Play Video Previews: Allows apps such as the App Store to automatically play video previews.
Limit Frame Rate: Limits the maximum frame rate of the display to 60 frames per second (on iPhone 13 Pro and iPhone 13 Pro Max).
You can apply these effects to specific apps; see Customize accessibility settings for specific apps on iPhone.
