How To End Call On iPhone | Red Button & Side Button Methods

Ending a call on an iPhone works by tapping the red End button on the call screen, or by pressing the side button when the Prevent Lock to End Call accessibility setting is turned off.

One wrong tap can send a call to the background instead of ending it, especially since Apple moved the end-call button position in iOS 17. The core function hasn’t changed, but muscle memory needs a quick reset. Here’s every reliable way to end an active call on an iPhone, including the button that works without touching the screen at all.

The Standard Way: Tap The Red End Button

During any active cellular or FaceTime call, the red End button appears on the call screen. One tap instantly disconnects the call. This is the primary built-in method and works identically whether you’re on a standard phone line or a FaceTime audio or video call.

In iOS 17, Apple moved the End button’s position within the call UI. On earlier versions it sat near the bottom center of the screen. After the update, it shifted to a location closer to the bottom-right corner of the in-call controls, which caught many users by surprise. The function itself never changed — the red button still ends a call with one tap.

The Side Button Method: End Calls Without Touching The Screen

On supported iPhones, pressing the side button once during an active call disconnects the call — but only if one specific accessibility setting is turned off. This is the quickest no-screen method for ending calls and works well when the phone is in your pocket or against your ear.

How To Enable Or Disable The Side Button For Ending Calls

The setting that controls this behavior is called Prevent Lock to End Call. Apple’s accessibility documentation confirms this toggle exists specifically to allow or block ending calls with the side button. It is off by default on most iPhones, meaning the side button ends calls automatically.

• Open Settings > Accessibility > Touch.
• Scroll to the bottom of the Touch settings menu.
• Check the toggle for Prevent Lock to End Call — if green, the side button will NOT end calls. If gray, the side button will end calls.

When Prevent Lock to End Call is off, pressing the side button during an active call immediately ends it. When it’s on, pressing the side button only locks the screen and the call continues. AppleVis community guidance and Apple’s own accessibility pages both point to this setting as the sole gatekeeper for the side-button disconnect behavior. when it works, the call screen disappears and your Home screen or lock screen reappears.

What About Ending Calls With Siri?

Siri can end a call, but it’s not as hands-free as most people expect. During an active call, you can say “Hey Siri, hang up” or “Hey Siri, end the call.” Siri will ask for confirmation before disconnecting. This was a change Apple introduced to prevent accidental hang-ups triggered by background noise or overheard speech — a notable safety design but not a truly one-step Siri action.

The Siri method works on any iPhone with Siri enabled and an internet connection. It’s a useful fallback when your hands are occupied but slower than tapping the red button or pressing the side button.

How To End Calls On iPhone: Methods Compared

Common Mistakes When Ending iPhone Calls

A few frequent errors cause people to accidentally keep calls active or silence them instead of ending them. Apple’s official support page and community discussions highlight these pitfalls.

• Pressing the side button once for incoming calls does NOT end or decline the call. It silences the ringer or vibration only. To decline an incoming call, press the side button twice quickly or tap the Decline button on screen.
• If Prevent Lock to End Call is on, pressing the side button will not end the call. Users often assume the button always disconnects. The toggle must be off for the side button to end calls.
• The End button position shifted in iOS 17. If you upgraded recently and find yourself tapping an empty spot on the screen, the button moved toward the bottom-right of the in-call controls. Look for the red circle in the new position.
• Double-pressing the side button during a call triggers Apple Pay or Emergency SOS, not a call-ends. Single press is the method for ending a call; double press launches different features entirely.

How To End A Call When The Screen Goes Black

If your iPhone’s screen turns off during a call and you can’t wake it by tapping, press the side button once to wake the screen, then tap the red End button. If the screen still won’t respond, press the side button twice quickly to invoke Emergency SOS — but this is not a recommended way to end a call. Instead, wait for the other party to hang up, or restart the iPhone by pressing and holding the side button plus either volume button until the power-off slider appears, then slide to power off and power back on. This resets the call and the interface.

Ending Calls On iPhone: Quick Recap

The surest method is tapping the red End button on the call screen after iOS 17 — the button itself works the same, it just lives in a slightly different spot. The side button method is the fastest when your hands are busy, as long as Settings > Accessibility > Touch > Prevent Lock to End Call is turned off. Siri and Bluetooth headsets provide good fallback options. Skip the side button for incoming calls — a single press silences, a double press declines, but neither ends a call that hasn’t started yet. And if you’ve updated to iOS 17 and keep tapping air, look toward the bottom-right of the call controls for the familiar red circle.
