OnePlus recently launched the OnePlus 13 in China, bringing with it several enhancements and a refined user interface with OxygenOS 15. Among the software’s latest features, storage optimization has emerged as a highlight, allowing users to unlock over 5GB of additional usable space for apps and files. This innovation exemplifies OnePlus’s commitment to maximizing user convenience.
According to the company, OxygenOS 15 on the OnePlus 13 (our hands on review) uses around 20% less storage space than Oxygen OS 14 on the OnePlus 12, giving OnePlus 13 users additional room for their apps, photos, and files.

OxygenOS 15 includes optimizations in how storage is managed and allocated. According to Android Authority, OnePlus achieves this optimization by resizing the “super” partition, which holds critical system files across various sub-partitions. Android devices use a set of dynamically resizable partitions within the “super” partition to facilitate updates and maintain system integrity. If OnePlus makes the super partition too small, the device may not support future updates. On the other hand, if it’s too large, it wastes valuable storage space for user data.
Developer MlgmXyysd, known for sharing Android system insights, revealed that while the OnePlus 12’s super partition consumed around 16GB, the OnePlus 13’s super partition is reduced to approximately 14.3GB.
This approach with the OnePlus 13 also involves minimizing superfluous files in the OS. The company also reportedly eliminated preloaded wallpapers and redundant resources, while still allowing users to download these on demand. This leaner design reduces storage consumption without compromising system performance.
Additionally, OnePlus’s use of compressed file systems, specifically EROFS (Enhanced Read-Only File System), further reduces the footprint of system files while maintaining speed and reliability.
Google’s Android update framework plays a role in OnePlus’s storage strategy, enabling a more flexible approach. When major updates roll out, the system can temporarily use storage from the user’s partition to facilitate the process. This adaptive feature means that despite reducing the super partition, updates should continue smoothly.
