AICore is turning 128GB Android phones into a storage nightmare

16 May 2026, 13:30 by Ben Khalesi · Android Police

Google’s best pitch for AI on Android is also the one that makes its storage tiers sting most.

The company wants phones to handle sensitive tasks offline, with local models doing the work instead of sending everything to a server.

Some Android users are seeing AICore take up over 10GB in their storage settings, and for a few, it’s so bad that they can’t install apps without clearing space first.

On-device AI may be the privacy-friendly path, but it needs hardware infrastructure.

Android phone manufacturers are still selling 128GB models, like that’s plenty. It really isn’t anymore.

Why does Android AICore eat so much storage?

Android AICore is a background service that manages machine learning models stored on your phone.

It helps run features like scam detection, audio transcription, Pixel Screenshots, and other similar tools.

You can turn it off and get some space back, but that means taking away the AI features your phone was sold with, which is a big part of the pitch now.

Manufacturers are pushing AI much harder than any meaningful hardware upgrades lately.

Google recently updated its support documentation to explain why AICore can balloon.

When the system updates a local model, AICore keeps both old and new versions on the device for up to three days as a rollback option. So if the new model breaks something, the phone can return to the previous version.

From a technical standpoint, I get the decision. Nobody wants the AI feature to fail and then have to download gigabytes to fix it. But the duplicate data is a lot.

On a 256GB phone, that’s annoying. On a 128GB phone, it can be the difference between installing an app and spending your afternoon deleting videos.

Modern phones have outgrown 128GB

The number printed on the box is already generous. A 128GB phone formats to roughly 119GB of usable space.

Android can take about 20GB. An AICore fail-safe spike can grab another 10GB. That leaves about 90GB for the rest of your life on the phone.

But people also aren’t using phones the way they did back when 128GB felt generous.

Cameras shoot 4K videos now. Messaging apps pile up photos and clips. Pretty much every app, from Spotify for music streaming to Google Maps for navigation, keeps some cache on the device.

Now, system AI models want permanent space, plus extra room whenever they update.

The business case for weak base storage

Storage management was once mostly a budget-phone headache. It shouldn’t be part of owning a premium phone, or even a mid-tier one.

Phone makers know 128GB is tight. They keep shipping it because it protects the sticker price.

Apple has already moved the iPhone 17 line to 256GB as the floor. Samsung does the same with the Galaxy S26 and S26+. OnePlus and Xiaomi also start their flagships at 256GB.

So when Google still sells the Pixel 10 and Pixel 10 Pro with 128GB, it’s penny-pinching dressed up as choice. And somehow, the Pixel 11 is rumored to still start at 128GB. Come on, Google!

The economy also got worse in 2026. The tech industry shifted production into high-bandwidth memory for AI data centers, which squeezed the supply of flash memory for phones.

Moving every base model to 256GB costs money, and manufacturers would rather not eat that cost. So the 128GB tier stays alive as the advertised entry point.

Google launched the Pixel 10 Pro at $999 with 128GB of storage. Samsung moved the base Galaxy S26 to 256GB, but its starting price climbed to $899. Both choices tell the same story.

Higher storage is becoming necessary, but companies still want a lower “starting at” price, or they want customers to pay more when the base spec finally catches up. The pressure lands on the buyer either way.

128GB can’t carry the AI era

AICore’s storage spike makes the problem visible, but the underlying issue is bigger than one Google service.

Local AI models are becoming part of the baseline smartphone load, like the operating system and camera pipeline.

If a base phone cannot absorb model updates, media capture, and normal app growth without collapsing, it should not be the base phone anymore.

128GB had a long run. For modern Android flagships built around AI, it’s done.
