Your iPhone 16 isn’t supposed to glow around the edges like the flashy ads suggest—but there is one legitimate way to trigger that subtle edge lighting effect Apple designed. If you’ve been searching for hidden settings or wondering why your phone isn’t lighting up like the commercials, you’re not alone. Millions of iPhone 16 users are discovering that the “edge glow” is strictly tied to Apple Intelligence features in iOS 18, not a standalone setting. This guide reveals exactly how to activate the authentic edge lighting, troubleshoot unwanted illumination, and understand what’s actually possible with your device—no misleading claims or false promises.
The iPhone 16’s edge lighting effect only appears during specific Apple Intelligence interactions, primarily when activating Siri. Unlike the dramatic glowing edges shown in marketing materials, the real effect is subtle: colored lines radiate from the screen edges when Apple Intelligence is engaged. This isn’t some hidden feature waiting to be unlocked—it’s a visual indicator built directly into iOS 18.1 and later versions, and it only works on iPhone 16 and iPhone 15 Pro models. If you’re not seeing this glow during Siri activation, your Apple Intelligence settings are likely disabled, or you’re using an older iPhone model that lacks this capability.
Activate iPhone 16 Edge Glow Through Siri
The only legitimate way to make your iPhone 16 light up around the edges is through Apple Intelligence-powered Siri interactions. This isn’t a special setting you toggle on—it’s an automatic visual feedback mechanism that activates when Apple Intelligence processes your requests.
Trigger Edge Glow with Side Button Press
- Press and hold your iPhone 16’s side button (don’t just tap it)
- Watch the pressed edge—you’ll see colored lines radiate outward across the screen
- Release the button after giving your Siri command
- Observe the fade effect—the glow naturally diminishes after Siri responds
This activation method works consistently when Apple Intelligence is enabled. If you don’t see the glow, check that you’re pressing (not tapping) the side button and that your iOS is updated to version 18.1 or later. The glow effect typically lasts 2-3 seconds after you finish speaking, providing visual confirmation that Siri is processing your request through Apple Intelligence.
Activate Edge Glow Using Voice Commands
- Say “Hey Siri” clearly in a moderately quiet environment
- Look at the bottom edge of your screen—glow should emanate upward from the display boundary
- Continue speaking your full command without pausing
- Note the effect duration—the glow disappears shortly after Siri completes its response
Voice activation creates a slightly different glow pattern than the side button method. With “Hey Siri,” the illumination originates from the bottom edge and moves upward, whereas physical button presses generate glow from the side you’re pressing. This visual feedback helps confirm that Apple Intelligence—not the basic Siri—is handling your request, which explains why older iPhone models show the traditional Siri orb instead of edge lighting.
Confirm You Meet All Activation Requirements
Before troubleshooting missing edge glow, verify these critical requirements:
– iPhone 16 or iPhone 15 Pro—older models lack this hardware capability
– iOS 18.1 or newer—early iOS 18 versions didn’t include this feature
– Apple Intelligence enabled in Settings (not just Siri)
– Siri voice feedback turned on—text-only mode disables visual effects
– Device not overheating—thermal throttling can disable Apple Intelligence features
If you’ve recently updated to iOS 18 but don’t see the edge glow, check Settings > Apple Intelligence & Siri to ensure Apple Intelligence is toggled on (green). The feature automatically disables if your device lacks sufficient processing power or storage space—iPhone 16 requires at least 8GB free storage for full Apple Intelligence functionality.
Disable iPhone 16 Edge Lighting When Unwanted

While the Siri edge glow provides useful visual feedback, some users find it distracting or want to conserve battery. Disabling it requires turning off Apple Intelligence completely—there’s no standalone setting for the glow effect alone.
Turn Off Edge Glow in Four Steps
- Open Settings and scroll to “Apple Intelligence & Siri”
- Toggle off Apple Intelligence at the top of the screen
- Confirm with “Turn Off Apple Intelligence” when prompted
- Restart your iPhone to ensure all visual effects are removed
This process takes less than 30 seconds and immediately eliminates the edge glow during Siri interactions. After disabling, Siri will revert to the traditional orb interface without any edge lighting effects. Important: Don’t expect to find a dedicated “Edge Glow” setting—Apple intentionally bundles this visual effect with the broader Apple Intelligence feature set.
What You Sacrifice by Disabling Edge Glow
Turning off Apple Intelligence to eliminate edge glow means losing these valuable features:
– Writing tools in Messages, Mail, and Notes
– Notification summaries that prioritize important alerts
– Visual intelligence for identifying objects through your camera
– Enhanced Siri responses with ChatGPT integration
– Type to Siri functionality for silent interactions
Your basic Siri voice commands will still work, and core phone functions remain unaffected. However, you’ll miss out on the most advanced AI capabilities that differentiate iPhone 16 from previous models. Consider this tradeoff carefully—many users find the subtle edge glow a small price for Apple Intelligence’s productivity benefits.
Troubleshoot Unexpected iPhone 16 Edge Illumination
If your iPhone 16 edges glow when you’re not using Siri, you’re likely experiencing either a display anomaly or confusion with marketing visuals. True edge lighting only occurs during Apple Intelligence interactions—persistent glow indicates something else is happening.
Diagnose Non-Siri Edge Glow Causes
Check these common culprits first:
– Extreme brightness settings above 90% can create screen halo effects
– Night Shift mode sometimes causes warm edge glows in dark environments
– True Tone adaptation may make edges appear subtly illuminated
– Screen damage near edges often manifests as light leaks
– Third-party cases pressing against the display perimeter
Perform this quick diagnostic test: In a dark room, open a pure black image and look for any light emission around the screen edges. True edge lighting from Apple Intelligence appears as colored lines during activation—not a constant glow. If you see persistent illumination, it’s likely a display issue rather than the intended Siri effect.
Fix Hardware-Related Edge Glow Issues
For persistent, non-functional edge illumination:
1. Adjust brightness to 70% or lower to eliminate screen artifacts
2. Disable True Tone (Settings > Display & Brightness) for testing
3. Remove your case and check if pressure against edges causes glow
4. Clean screen edges with microfiber cloth to remove debris
5. Visit Apple Support if glow persists—may indicate screen defect
Pro Tip: If your screen shows constant edge glow even when off, this indicates a serious display malfunction requiring professional repair. Genuine Apple Intelligence glow never appears when the screen is inactive.
Replicate iPhone 16 Marketing Glow Effects Safely
The dramatic edge lighting in iPhone 16 advertisements doesn’t exist on actual devices—it’s purely a marketing concept. Don’t waste time searching for non-existent settings; instead, use these legitimate alternatives to create similar visual effects.
Create Real Edge Glow with Accessories
Third-party solutions that actually work:
– LED edge cases with built-in light strips (Mophie, Nillkin)
– Programmable LED rings that attach to charging ports
– Bluetooth-controlled lighting synced with notifications
– Battery cases with ambient lighting (Anker, Belkin)
These accessories create actual physical glow around your iPhone’s perimeter, unlike software “solutions” that merely simulate the effect on-screen. Most connect via Bluetooth and offer app control for color, intensity, and notification patterns—providing the dramatic edge lighting Apple’s marketing suggests.
Software-Based Alternatives
For those preferring non-hardware solutions:
– Live wallpapers with animated edge effects (Wallpaper Studio 10)
– Dynamic Island customization apps that extend visual elements
– Notification light apps using screen edges (requires Always-On Display)
– Jailbreak tweaks like “GlowDock” (not recommended for most users)
Important Reality Check: No app or setting can create true hardware-based edge lighting. The iPhone 16 lacks physical LED strips around its display perimeter—the only authentic edge glow remains the Siri activation effect through Apple Intelligence.
Future iPhone 16 Edge Lighting Possibilities
While current edge glow is limited to Siri activation, Apple may expand these visual effects through future iOS updates. Industry analysts predict more sophisticated edge lighting could arrive as early as iOS 18.4.
Expected Edge Lighting Features
Most likely additions:
– Notification-specific pulses (blue for messages, red for calls)
– Ambient light reactions using True Tone sensors
– Customizable color schemes for different app categories
– Charging status indicators along screen edges
These potential features would still rely on software manipulation of the existing display rather than new hardware. True hardware-based edge lighting would require significant design changes unlikely to appear before iPhone 17 or later models.
When to Expect New Edge Effects
Realistic timeline:
– iOS 18.2-18.4 updates: Minor glow variations (late 2024)
– iOS 19 release: More substantial edge lighting features (fall 2025)
– iPhone 17 launch: Possible hardware-based edge lighting (2025)
For now, manage your expectations—the iPhone 16’s edge glow is intentionally subtle and strictly tied to Apple Intelligence functionality. The marketing visuals represent conceptual designs, not current capabilities.
