PCMag's iOS 27 list gates four of its ten features behind an iPhone 15 Pro
The update installs free on any iPhone 11 or later. The Siri that finds a PDF and drafts it into an email starts at the iPhone 15 Pro. That is one version number with two capability sets to support.

What happened
- PCMag says iOS 27 is out now and installs on the iPhone 11 and newer, including the second-generation iPhone SE.
- A note above PCMag's feature list says the first four Siri items require an iPhone 15 Pro or newer, while every supported phone gets the core platform features.
- Those first four are agentic multi-step Siri, a dedicated Siri chat app, Visual Intelligence on-screen queries and Spatial Reframing in Photos.
- The software landed the same week as Apple's new hardware, with PCMag naming a $1,999 iPhone Duo and an iPhone 18 Pro on preorder before its Sept. 18 release.

Why it matters
- constraint "Update to iOS 27" stops predicting what a user can do, so a support script or in-app prompt keyed to the version number will mislead the iPhone 11 through 14 owners who already updated.
- decision A team planning a Siri-driven path now has to fund a manual path in the same release or accept that the feature reaches only the 15 Pro owners in its base.
- exposure Whoever staffs the support queue takes the questions from users who read the numbered feature list and never saw the model requirement sitting above it.
Someone with an iPhone 13 takes the update this weekend, opens Siri, and asks it to find the PDF that just downloaded, rename it, and draft it into an email. The iPhone 13 runs iOS 27 [1]. But that chain is PCMag's own example of agentic Siri, and it needs an iPhone 15 Pro or newer [4][3].
Four of the ten features on PCMag's list sit behind that hardware requirement, so six of them work on every phone back to the iPhone 11 [1]. The six are surface work: icons anywhere on the grid, extra-large widgets, custom lock screen buttons, a sketch canvas inside Messages, and a slider for Liquid Glass translucency [8]. The four gated ones are the features that do something on the user's behalf, including the persistent Siri chat app that keeps history across iPhone, iPad and Mac by iCloud, on-screen queries like "Where was this photo taken?", and generative reframing in Photos [5][6][7]. PCMag calls all ten "game-changing" [11].
The two floors are four numbered generations apart: the OS starts at the iPhone 11, the assistant starts at the 15 Pro [2].
Teams treat OS adoption as the gate, so when the version chart fills in, the feature counts as live for the base. Users install a free upgrade [2], then judge the assistant on the four items at the top of every feature roundup. PCMag puts the model requirement in a note above the list; the four entries do not carry it [3]. The list does not say how a third-party app takes part in one of those Siri chains.
So the version check in your code is no longer the right check. The split does not fall evenly across your roadmap either: it falls on anything that expects Siri to do the chaining.
Two axes separate the planned items. The first is whether an item depends on Siri chaining actions across apps, or only on a screen surface every supported iPhone has. The second is whether a user on an ungated phone can see that something is missing, or whether the absence is invisible to them. Items that depend on the chain and leave a visible hole need the manual path shipped in the same release. Items that depend on the chain and degrade quietly can ride hardware turnover.
What to watch
- Whether Apple publishes a model list for the Siri features, or leaves the requirement to a note in feature roundups.
- Whether the Siri chat app and its iCloud history show up on an iPad or Mac belonging to someone whose iPhone cannot run it.
- Whether documentation appears for how a third-party app becomes part of a multi-step Siri chain.
