You cannot enable a system-wide split-screen mode on iPhone the way you can on an iPad. Instead, choose the multitasking method that fits what you are trying to do: keep a video visible, move quickly between apps, or use a multi-panel layout inside one app.
For Watching While Using Another App
Use Picture in Picture when the video or calling app supports it. The video becomes a movable floating window while you open another app.
For Moving Between Two Apps
Open the App Switcher, or swipe across the bottom edge on a Face ID iPhone to jump between recent apps. This is often faster than trying to fit two full apps on the smaller display.
For Two Web Pages or Panels
A browser or third-party app may provide multiple panes within its own interface. That is an app feature, not an iPhone Split View mode.
Why You Cannot Turn On iPad Split View
iPadOS includes system multitasking features that iOS does not expose on iPhone. There is no hidden Settings switch that enables iPad-style side-by-side apps on an iPhone.
Frequently Asked Questions
Can a third-party app add true Split View?
No. It can only create its own multi-panel interface.
Can I use Picture in Picture with every video app?
No. The app and content must support it.
Will a larger iPhone screen unlock Split View?
No. iPhone screen size does not add iPadOS Split View.
Summary
iPhone does not have native iPad-style split screen. Use Picture in Picture, the App Switcher, or an app’s own multi-panel interface instead.
