Listen to Books With the Screen Off: A Complete Fix Guide

You pocket your phone mid-chapter, the screen locks, and silence. If you're trying to listen to books with the screen off, that silence is one of the most consistent annoyances in mobile listening. It hits people on Audible, Libby, Apple Books and nearly every audiobook app, and it feels random, because sometimes it works and sometimes it doesn't.

The good news: this is almost never a hardware problem. Your phone isn't broken. It's a permissions or settings conflict between the operating system, its battery-management layer, and the app. Fix the right setting and it goes away in under two minutes. Some apps, like ReadLume, are built around screen-off playback from the start and sidestep it entirely, but for the apps you already use, there's a clear path.

Why it happens

When you lock your phone, the OS pushes most apps into a restricted background state to save battery. That's intentional, and generally good. The exception is audio: both iOS and Android have a special background-audio session that apps can declare, which tells the OS to keep the process alive and the audio pipeline open. When an app registers for it properly, locking the screen does nothing to playback. Trouble starts when that session is interrupted, never started correctly, or blocked by a secondary setting.

Three culprits cause it in almost every case:

• Battery optimization or power-saver mode killing background processes
• OS permissions that weren't granted, or got reset during an update
• An app-level setting, or an outright bug, that pauses on lock

iPhone settings that cut off background audio

Background App Refresh

This is iOS's system for letting apps keep working behind other apps. For some audiobook apps, turning it off breaks background audio depending on how they've structured their audio session. Go to Settings > General > Background App Refresh and make sure it's on for your app. A lot of people disable it system-wide to save battery without realizing it's a side effect; re-enable it just for the audiobook app.

Other iOS settings worth checking

Auto-Lock doesn't stop audio on its own, iOS doesn't pause audio when the screen turns off by design. If playback dies every time you lock, the cause is in permissions or an app setting, not the lock itself. Screen Time and Content & Privacy Restrictions can also interfere in non-obvious ways, so check those if they're set up. One Audible-specific fix that works for many people: Settings > Privacy & Security > Media & Apple Music, find the app, revoke the permission, then re-grant it, which resets the audio-session handshake.

Android battery settings that kill background audio

Why Android hits harder

Android's battery optimization is more aggressive than iOS and varies by manufacturer, Samsung's "Sleeping apps," Pixel's "Adaptive Battery," and others. Different names, same behavior: the OS decides your audio app doesn't need to run in the background and cuts it off. The critical setting is the app's individual battery mode. "Optimized" sounds fine but is often enough to kill background audio, and "Restricted" will explicitly block it. You want Unrestricted.

How to whitelist your app

Go to Settings > Apps > [your app] > Battery and set it to Unrestricted (some devices say "Don't optimize"). On Samsung, also check Settings > Battery > Background usage limits and remove the app from "Sleeping apps" and "Deep sleeping apps," anything in deep sleep never runs in the background. Turning off Battery Saver entirely while you troubleshoot is the fastest way to confirm whether that's the cause. If your app streams rather than downloads, also enable background data, since Data Saver can stall audio mid-chapter even after the battery fix.

App-specific fixes for Audible and Libby

Audible

On iPhone: disable Low Power Mode, confirm Background App Refresh is on for Audible, and try the Media & Apple Music permission reset above. On Android: set Audible's battery mode to Unrestricted and confirm it isn't in any sleeping-apps list. That covers most cases. If it still cuts out, sign out and back in, then update or reinstall, several recurring Audible bugs have been tied to specific versions.

Libby

Libby leans on a continuous media session that can break if the app gets backgrounded at the wrong moment. The most reliable first move is to force-quit Libby completely and reopen it before a session, which resets the media session cleanly. On Android, adding Libby's lock-screen widget helps keep the session alive; downloading the audiobook within Libby rather than streaming it is also worth trying.

Quick fixes at a glance

Run these in order; the whole sequence takes about five minutes.

1. Turn off Battery Saver or Power Saving mode.
2. Set the app to Unrestricted (Android) or confirm Background App Refresh is on (iPhone).
3. Remove the app from Samsung's Sleeping / Deep sleeping lists.
4. Force-quit the app and reopen it.
5. Restart the phone.
6. Reinstall the app as a last resort.

If the problem returns after an OS update, the update likely reset a permission, just run the checklist again. And if playback still stops after all of this, it's likely a bug in that app on your specific OS version, which is a fair signal to consider an app that treats continuous playback as a first-class feature.

Apps built for screen-off listening from the start

Most mainstream audiobook apps were designed for active, screen-on use first, with background playback bolted on later, which is exactly why the permissions dance exists. For readers going through chapters fast, especially web-novel fans tracking daily serials, those interruptions stack into a real usability problem. That's the gap ReadLume was built to close: hands-free, screen-off fiction listening with lock-screen controls, automatic chapter advancement and background playback as core features, not add-ons. If you want it running cleanly from the first session, follow the hands-free setup guide. The free tier covers personal PDF and EPUB files, and web-novel plans start at $2.50/month.
