Tech Gear Hub explains what GSMArena reported on November 1, 2026: after updating to iOS 27, some iPhone owners found Apple Intelligence taking up roughly 15GB of storage — with reports ranging from about 9GB to 16GB depending on the phone. For most US iPhone buyers, the takeaway is simple: if you buy a new iPhone now, choose 256GB over 128GB unless you are certain you keep almost everything in iCloud, because Apple Intelligence storage does not fully come back even if you turn the features off.

Quick Verdict: iOS 27 Apple Intelligence storage
Apple Intelligence on iOS 27 can reserve around 15GB of your iPhone's storage for its on-device AI models, GSMArena reported on November 1, 2026, citing user reports after the iOS 27 update. The exact amount varies by phone — some owners saw about 9GB, others about 16GB — and turning Apple Intelligence or Siri off did not restore the space in those reports. GSMArena's workaround that did work was switching Siri's language to a variant Apple Intelligence does not support, such as South African English, which stops the AI models from loading locally. Our verdict: do not panic, but do buy more storage than you think you need, and check your free space before and after any major iOS update.

What GSMArena actually reported
According to GSMArena's November 1, 2026 report, iPhone users who updated to iOS 27 found Apple Intelligence taking around 15GB of internal storage. The report stresses that the figure is not fixed: allocation varies from phone to phone, with some users seeing about 16GB inaccessible after the update and others as low as about 9GB. The storage is taken even in regions where Apple Intelligence cannot be used — GSMArena specifically notes EU iPhone owners who cannot use the features still lost the space.
Two details in the report matter for buyers. First, disabling Apple Intelligence or Siri altogether did not seem to restore the space in the cases GSMArena covered. Second, Apple has started pushing its iCloud storage service more aggressively to affected users, urging them to subscribe and back up their data. That timing will look suspicious to many owners, even though the storage issue itself comes from on-device AI models, not from iCloud. We are reporting user reports as reported — Apple has not, in the GSMArena piece, given a single official number for every model, so treat 15GB as a typical reported figure, not a guaranteed one.
The quotable numbers are stark on a 128GB phone: 15GB is nearly 12% of the advertised storage, before your photos, apps and videos. On a 256GB phone, the same 15GB is under 6%. That difference is why this news story matters more than a typical software footnote — it changes which storage size is sensible to buy.
Why Apple Intelligence needs so much storage
Apple Intelligence is designed to run largely on the device, for privacy and speed, rather than sending every request to a server. That design needs large AI models stored locally on the phone — language models, image models and the data they use to work without an internet connection. iOS 27 expanded those on-device capabilities, per GSMArena's framing of the update as Apple's attempt to catch up in AI, and larger models mean larger local storage.
This is not unique to Apple: on-device AI on Android phones also reserves gigabytes of storage. The difference here is scale and surprise. A 15GB reservation that arrives with a routine-looking software update, and that does not fully reverse when you switch the feature off, feels like a storage tax — especially on a 128GB iPhone that already loses several gigabytes to iOS itself before you install a single app.
How to check and free space on your iPhone
First, check where you stand. On your iPhone, go to Settings, then General, then iPhone Storage, and wait for the breakdown to load. Look at how much space iOS itself and system data now occupy, and compare it with what you remember before the update. If you are close to full, the fastest honest fixes are deleting large videos, offloading unused apps, and moving your photo library to iCloud Photos or a computer — not deleting the AI models directly, which iOS does not offer as a simple button.
GSMArena's reported workaround is a language trick: change Siri's language to a variant that Apple Intelligence does not support for your region — the report gives Canadian, Irish, South African or New Zealand English as examples for users who still want English Siri — because Apple Intelligence and Siri only fully work when the device and Siri languages are set to US or UK English. That workaround stops the models from loading, but it also means giving up Apple Intelligence features and possibly changing how Siri understands you. Try it only if you do not use Apple Intelligence and you need the space urgently, and note that Apple could change this behavior in a future update.
Do not fall for storage-cleaner apps that promise to delete system files — iOS does not let third-party apps touch those files, and the apps that claim otherwise are usually selling subscriptions. The safe moves remain the boring ones: fewer downloaded videos, fewer games you no longer play, and photos backed up elsewhere.
What this means if you are buying an iPhone now
If you are shopping for an iPhone today, this story should move your storage choice up one tier. A 128GB iPhone in late 2026 leaves you roughly 110GB or less for everything else once iOS and a 15GB Apple Intelligence reservation are counted — and 4K video, large games and a few years of photos eat that quickly. A 256GB iPhone costs more up front but removes the constant storage anxiety that pushes people into monthly iCloud subscriptions they did not plan for.
Our full buying guide published today covers the iPhone 16 vs iPhone 15 choice in detail — including which model supports Apple Intelligence at all. our iPhone 16 vs iPhone 15 buying guide The short version: every iPhone 16 supports Apple Intelligence, while only the iPhone 15 Pro and Pro Max do among the iPhone 15 family. If you buy an iPhone 15 Pro or any iPhone 16, expect the same storage reservation to apply once you update to iOS 27.
Check the current price of the Apple iPhone 16 (128GB, Renewed, Unlocked) on Amazon — and if your budget stretches, choose the 256GB variant of whichever iPhone you buy. Renewed listings vary by storage and condition, so confirm the storage size on the listing before ordering; prices change often.
Who should care — and who should not worry
Care most if: you own a 128GB iPhone, you shoot a lot of video, you keep large games installed, or you are about to buy a new iPhone and were planning on the base storage tier.
Worry less if: you own a 256GB or 512GB iPhone, you keep most photos in iCloud, or you rarely fill your phone past half full. For you, 15GB is an annoyance, not a crisis.
Who should NOT act on this news alone: do not rush to replace a working iPhone just because of a storage report, and do not switch Siri's language if you actually use Apple Intelligence every day — the workaround trades away features you may need. Check your own storage first; if you still have 30GB or more free, this story changes nothing about your daily use.

Frequently asked questions
How much storage does Apple Intelligence use on iOS 27?
Around 15GB in typical user reports covered by GSMArena on November 1, 2026, with a reported range of about 9GB to 16GB depending on the phone. It is not a single official figure for every model.
Does turning off Apple Intelligence free the storage?
Not fully, according to the GSMArena report. Disabling Apple Intelligence or Siri altogether did not seem to restore the space in the cases covered.
How can I reclaim storage after the iOS 27 update?
GSMArena reports that switching Siri's language to an unsupported variant, such as South African English, stops the AI models from loading locally. The safer everyday fixes are deleting large videos, offloading unused apps and backing up photos elsewhere.
Does Apple Intelligence take storage even where it cannot be used?
Yes, per the GSMArena report. Apple Intelligence took up storage even for EU iPhone owners who cannot use it in their region.
Should I buy 128GB or 256GB iPhone now?
Buy 256GB if you shoot video, keep large games or plan to keep the phone for years. On a 128GB phone, a 15GB Apple Intelligence reservation leaves noticeably less room for everything else.
Is this storage issue a reason to avoid updating to iOS 27?
Not on its own. iOS updates also bring security fixes. Check your free space first, back up your phone, and update — then clear space if you need to, rather than skipping security updates.
