Apps to Use Up to 12GB of RAM on High-End iPad Pro When Running iPadOS 15, Up From 5GB

iPadOS 15 allows developers to allocate more RAM for their apps. By allowing apps to grab more memory for their app, they can run faster and more efficiently.

An entitlement gives developers the ability to let iPadOS know that certain functions of their apps may perform better if they have access to more system memory. Until iPadOS 15, Apple capped the amount of memory an app can use, which ensured that a single app does not use all of a device’s memory, impacting other core system functions.

It appears that on the highest-end M1 iPad Pro, apps can use up to double the amount of RAM that was previously allowed. This, from information provided by the developers behind the graphic design app Artstudio Pro.


According to their findings, on the highest-end ‌M1‌ ‌iPad Pro‌, which boasts 16GB of RAM, apps can request through the entitlement to use up to 12GB of that available memory. On other ‌M1‌ ‌iPad Pro‌ models, which contain only 8GB of RAM, apps can request up to 6GB.

In both cases, even if an app informs iPadOS that additional memory is needed, iPadOS still allocates a 2GB buffer for the app, on top of the 4GB available for 16GB ‌iPad Pro‌ models, and the 2GB free for the other models.

The new change is likely to be most beneficial to graphically intensive apps, such as those for drawing, modeling, and photo and video editing. (Like Artstudio Pro.)

Apple says the new entitlement will be available on “supported devices,” and at this point, which devices are supported beyond the new ‌iPad‌ Pros is unknown.

‌iPadOS 15‌ will launch alongside iOS 15, watchOS 8, and tvOS 15 on Monday, September 20.
