iOS 26.4 Highlights Your Personal Hotspot Data Usage More Prominently
Source: MacRumors
iOS 26.4 moves the feature to show how much mobile data connected devices have used via Personal Hotspot to a more prominent and easily accessible location.

Now available in Personal Hotspot settings below the “Maximize Compatibility” toggle, the functionality breaks down data usage by device, with non‑Apple devices simply showing up as a group of “Other Devices.” Total Personal Hotspot data usage is also displayed.
Previously, the feature was buried in Cellular settings. It may be particularly helpful to those with a data limit on their carrier plan.
iOS 26.4 is now available in beta to developers. A public beta will be released in the near future, and Apple plans to roll out the update in the spring.
