You can control which poses will enter StandBy on iPhone Duo.
You can also have iPhone enter Standby only while charging.
Here’s the new StandBy onboarding for iPhone Duo.
The Duo illustrations will show animated previews of StandBy faces, customization, and adding new faces, including a localized “Customize” button.
The assets are stripped from the Duo simulator runtime.

Here’s the full list of preview images Apple has prepared to match the hardware color options of its home device.
All of these assets are bundled in PhotosUIPrivate in the iPhone Duo simulator runtime.
Apple’s Home device may come in four finishes: Silver, Space Gray, Starlight, and Rose Pink.
The Photo Face setup screen picks its preview art based on the hardware color the device reports.
The device’s housing may also show in setup screens once device assets are available.
These finishes previously appeared in J490 setup code in macOS 26.7 RC1. @MacRumors reported them as “mystery colors” in August.

Setting up Apple’s upcoming Home device includes a new step: creating a Photo Face.
It’s the same Photo Face coming to StandBy on iPhone Duo. That might explain why Apple hasn’t officially made StandBy available in the simulator.
Photo Face requires iCloud Photos. During setup, iPhone sends a few full-resolution “cold-start” photos so the face can display immediately. The device then downloads the rest from iCloud.
(“Apple device” is a fallback because CoreTypes doesn’t know the new device’s name.)

If you still live in “Siri with Apple Intelligence” land, here’s how to disable the blue floating button without disabling Writing Tools:
defaults write -g WTAffordanceUIControllerMinNumberOfLines -int -1
and restart your Mac.
The preference controls how many lines of text you need to select before the affordance shows up. The trick here is to set the number as high as possible (-1 selects the largest unsigned integer supported: 18,446,744,073,709,551,615).
To restore:
defaults delete -g WTAffordanceUIControllerMinNumberOfLines
You can disable it per app:
defaults write com\.apple.mail WTAffordanceUIControllerMinNumberOfLines -1
Here's how to disable Siri's new floating button in macOS 27
When Siri AI is enabled, macOS 27 adds a contextual "lightweight UI" when you type or select text. The floating button can expand into Ask Siri, Edit with Siri and Writing tools, or other contextual actions.
To disable it, run the following command in the Terminal:
sudo mkdir -p /Library/Preferences/FeatureFlags/Domain && \
sudo defaults write /Library/Preferences/FeatureFlags/Domain/WritingTools LightweightUI_macOS -dict Enabled -bool false
and restart your Mac. To restore:
sudo defaults delete /Library/Preferences/FeatureFlags/Domain/WritingTools LightweightUI_macOS

Software context: Starting with iOS 27, DiagnosticsService ships with BatteryResetControl (Diagnostic-6021). It supports getStatus and triggerReset operations.
A reset request specifies budSide and batterySerialNumber. AirPods firmware saves the serial in a service record, then resets battery statistics and algorithms.
getStatus returns hasBeenReset, dateOfLastSuccessReset, vendorOfLastSuccessReset, and statusOfLastResetAttempt.
iOS sends both requests through AAAppleCareAccessoryControl. We’ll see if Apple makes this available to third-party repair shops or Self Service Repair.

Xcode 27.2 beta 2 supports iPhone Duo, but you don’t get the fun Action Bar, even if you enable the preference.
You also can’t freely drag to rotate the device, quick-switch between poses with ⌘ + 1-5, or enable Table Mode to access StandBy in the simulator.
Device Hub in Xcode 27.1 has a hidden Action Bar specifically for iPhone Duo.
It gives you a lot more control over the device angle, and you can quickly switch between 5 device poses with keyboard shortcuts. There’s also a “Table Mode” control.
To enable:
defaults write com\.apple.dt.Devices com\.apple.dt.coredevicepop.useInternalV68ActionBar -bool true
and restart Device Hub.
The iPhone Duo simulator also comes with a hidden HingeStatePoster wallpaper.

Could we see Apple reuse the new StandBy renderer for iPhone Duo in their upcoming Home products?
Might explain why they haven’t previewed these five faces: Home Camera, Home Modular, Flow, Fade, Snoopy.
Code reveals five more StandBy faces for iPhone Duo:
• Home Camera: Single camera view or a grid of up to nine.
• Home Modular: Perhaps a Home accessory-focused Modular.
• Flow (ResponsiveArt): Possibly an animated, abstract face.
• Fade: No design details.
• Snoopy
