If you’re looking for a volume slider on your iPhone Lock Screen, use Control Center: open it while the phone is locked and drag the slider. Apple documents playback controls on the Lock Screen, but does not describe a setting that pins a permanent volume bar there.

How do I adjust the volume when my iPhone is locked?

  1. Open Control Center from the Lock Screen. On an iPhone with Face ID, swipe down from the top-right corner. On other iPhone models, swipe up from the bottom edge.

  2. Drag the volume slider to change the loudness. Apple says you can adjust volume in Control Center while iPhone is locked or while you’re using an app. See Apple’s instructions for adjusting iPhone volume.

Why can’t I see a volume slider on my Lock Screen?

The Lock Screen’s media controls and the volume slider are different controls. Apple documents Lock Screen playback controls such as play, pause, rewind, and fast-forward, but its guidance does not promise a permanent volume bar on the Lock Screen. The supported way to adjust volume while locked is through Control Center. Apple explains which features are accessible from the Lock Screen.

How do I get music controls back on my iPhone Lock Screen?

Start or resume playback in your media app, then check the Lock Screen for the Now Playing controls. If playback controls are unavailable, check that media playback controls are allowed under Settings > Face ID & Passcode or Settings > Touch ID & Passcode, under Allow Access When Locked. These controls let you operate playback; they are not a persistent volume slider.
