IOS 15 features that won’t be available on older iPhone models

iOS 15 is compatible with a wide range of devices, from the iPhone 6S, launched in September 2015, to the latest models in the iPhone 12 series. However, not all phones receive all the new capabilities that Apple introduced at WWDC 21 for the new operating system. Some models will receive only a few new features, interface changes and some of the functionality of the new updated Apple applications.

Here’s what’s missing from iOS 15 on some older iPhones

New capabilities for AI processing, or requiring better graphics chips, will only run on newer models. Thus, some functions related to Siri, playback or recording of processed sound or video calls via FaceTime will only be available on the last few generations of iPhone, Gizmodo announces.


The native video calling application from iOS, iPadOS and macOS, FaceTime, receives several new features, including the ability to integrate with calendar applications, as well as browser access, for alternative operating systems such as Android or Windows. However, the top features will only be available on Apple devices that have the necessary hardware.

One of these capabilities is Fashion Portrait, the ability that separates the subject from the background and adds a blur effect around the person. This capability will only be available on devices that have Face ID hardware. Also, Spatial Audio, ie playback of the sound in the direction in which it is displayed on the screen, will only work on newer models, which allow the use of this function.

Apple Maps

Apple Maps services are constantly improving, but they are far behind alternatives from Google and other competing companies. Apple will implement a mode of navigation with AR for Apple Maps, but it will only be available on newer device models. Also to be able to use display mode similar to Google Earth, which renders the entire planet in 3D, you will need an iPhone with Apple A12 processor, ie from the XR / XS generation to newer variants, such as iPhone 11 and iPhone 12.

New 3D details on maps, such as buildings and tourist attractions will also be limited to newer smartphone models.

Chei Digital

In the case of digital keys, Apple limits this feature to devices that have the necessary hardware. Not only NFC is needed, which integrates all iPhone models from 6 to now, but also one UWB sensor (ultra wide-band), which detects proximity to other devices. Thus, again, only iPhone XS / XR or newer phones will be able to use this capability.

Local AI functions

When it comes to AI capabilities, Apple will only allow devices with the A12 Bionic chipset or later to access them. Thus, iPhone X or 8 and older models will not be able to use the new features Live Text, which recognize the text in photos. Also, photo element recognition functions, such as dog breeds, or various objects (Google Lens style), will only work on the last three generations of iPhones on the market.

The same thing happens with Siri. The virtual assistant will not be able to run locally, ie without internet, than on devices with A12 or newer processor. Also in the Siri chapter come the new wizard customization functions and the ability to dictate text without being connected to Apple servers.


But a strange limitation is the one that does not allow you to zoom if you record using the capability QuickTake, which involves holding down the capture button in photo mode. Also, the 3D weather effects in the new weather app will not appear on older devices.

And the capabilities of “health”Lag behind older iPhone 8 models. Those who want to measure how“ straight ”they are, with the help of iPhone sensors, will not be able to do this on the iPhone 7 or 6S.

However, there is a feature that will only be missing from the iPhone 6S, as all iPhone models are compatible: Dolby Atmos and 3D sound effects when using AirPods Pro or AirPods Max.
