Have you recently noticed a sudden decrease in your smartphone’s storage space? If so, you may be surprised to learn that an app called AICore could be the culprit. Numerous Android users have reported that this system app can consume anywhere from 7GB to 11GB of storage. While this may seem excessive for a background service, Google has clarified that this behavior is intentional and serves as a safety feature rather than a bug.
AICore plays a crucial role in powering the local AI capabilities of your device, particularly on modern flagship smartphones. One of its key functions is managing Gemini Nano, which enables your phone to perform complex tasks locally instead of relying on cloud services. This local processing capability is responsible for features like scam detection, smart replies in messaging apps, and real-time audio transcriptions even when offline.
Given the inherently large size of AI models, it is not uncommon for them to require several gigabytes of storage space to function effectively. The apparent spikes in storage usage that users experience are often linked to a specific background process known as the update cycle.
Google has provided insights into how AICore handles updates to new AI models. During this process, both the old and new versions of the model are temporarily stored on the device for up to three days as a fail-safe measure. This approach ensures that if any issues arise with the new update, the device can revert to the previous version without the need to re-download large amounts of data. Once the system verifies the stability of the new model, it removes the old version to free up space for the updated one.
The impact of this temporary storage usage varies depending on the device’s storage capacity. While users with larger storage options may not notice a significant difference, those with 128GB models may find the 11GB consumption more noticeable. Although it is possible to reclaim this space by disabling AICore, doing so will disable many on-device AI features, such as grammar checks, translation services, and summarization tools. In most cases, it is advisable to allow the app to manage its own storage, as the “missing” gigabytes typically return within a few days.
