Apple first introduced screen recording in iOS 11, allowing users to easily capture on-screen activity. At the time, however, the company imposed a resolution cap of 1920 pixels — a limitation that remained unchanged even with the release of the iPhone 16 Pro Max.
For instance, on the iPhone 16 Pro Max running iOS 18, recordings maxed out at 884×1920 pixels, despite the device’s native resolution being 1320×2868 pixels. As a result, recorded videos appeared noticeably less sharp.
In the newly released iOS 26 beta, Apple has finally revised this limitation. The iPhone 16 Pro Max can now record at its full 1320×2868 resolution, delivering significantly clearer video quality.

Despite this substantial increase in resolution, Apple appears to have refined its video compression algorithms to prevent file sizes from ballooning. For example, a 12-second recording that previously produced an 18.9 MB file now generates a 24.2 MB file at the higher resolution — a modest increase relative to the gain in clarity.
This means longer recordings will not consume excessive storage space, especially when compared to 4K video capture, where file sizes are exponentially larger.
The official release of iOS 26 is scheduled for later this month. In addition to the upgraded screen recording resolution, the update introduces HDR recording, the option to disable screenshots in CarPlay, and enhanced features such as Visual Lookup.
