The short version: on a standard free YouTube account, the app will not play audio or video once you lock your iPhone or switch apps unless you pay for YouTube Premium, which opens up background play. There's a free workaround using Safari instead of the app, but it's fiddly and Google keeps tweaking it to make it less reliable. I'll walk through both so you can pick the one that suits how you use YouTube.
Why YouTube stops when you lock your phone
This isn't a bug. It's a business decision. YouTube makes a large chunk of its money from ads and from Premium subscriptions, and background play is one of the main things that paid tier is built to sell. If background play worked for free, a lot fewer people would pay the £12.99 a month (or around £129.99 a year) that YouTube Premium costs in the UK. So the app is deliberately coded to pause when it loses focus, unless your account is on Premium.
I think it's worth saying plainly: this is one of those features that writers tend to present as a "setting you're missing" when really it's a paywall dressed up as a technical limitation. There is no hidden toggle buried in Settings that opens up free background play on the official app. If a blog post tells you otherwise, be sceptical.
Option 1: YouTube Premium (the reliable fix)
If you watch YouTube a lot, podcasts, interviews, music, lectures, this is the straightforward answer. Here's what you get and how to set it up.
- Open the YouTube app on your iPhone
- Tap your profile icon top right
- Tap "Get YouTube Premium"
- Choose monthly or annual billing (annual works out roughly two months cheaper)
- Confirm payment through your Apple ID, since iOS subscriptions go through Apple's billing, which is why Premium can sometimes look a few pounds more expensive on iPhone than on a browser
- Once active, lock your phone or swipe to another app, the video keeps playing with audio, and a small floating player appears when you need it
Premium also removes ads entirely and adds YouTube Music Premium, offline downloads, and picture-in-picture that behaves the way you'd expect. If you're someone who listens to YouTube the way others listen to a podcast app, say you run a podcast and want to track guest episodes or competitor content while cooking dinner or on a commute, this pays for itself in convenience within a few weeks.
Option 2: the Safari workaround
If you don't want to pay, there's a free method that uses Safari's desktop site mode rather than the app. It works, but it's more sensitive to iOS and YouTube updates than people admit, and it can stop working from one week to the next without warning. Here's the process as it currently stands:
- Open Safari, not the YouTube app, and go to youtube.com
- Find the video you want and start playing it
- Tap the "aA" icon in the address bar
- Select "Request Desktop Website"
- The page will reload in desktop layout, keep the video playing
- Press the volume up button once (this seems to matter, it's an odd quirk but it nudges Safari to treat the tab as active audio)
- Lock your phone or swipe away from Safari
- Audio should keep playing; if it cuts out immediately, reopen Safari, play the video again, and try the volume button step before switching apps rather than after
Worked example: say you're commuting on a train and want to listen to a 40-minute interview without paying for Premium. You open the desktop site version in Safari, hit play, request the desktop site, tap volume up, then lock your phone and put it in your pocket. For most people this holds for the full 40 minutes. Where it tends to fail is when a phone call comes in, when you open another app that also wants audio focus like Spotify or a voice memo app, or when iOS runs a background refresh that kicks Safari's audio session. If that happens, you have to open up, reopen Safari, and the video usually resumes from where it left off, though sometimes it resets to the start of the current ad.
The uncomfortable bit nobody likes to say out loud: this workaround is against YouTube's intended behaviour, not against any law, but Google has tightened it several times over the past few years specifically because it costs them Premium revenue when it works too well. There's no guarantee it'll still work next month. If you depend on background play daily for work, don't build a routine around a loophole that a server-side update can kill overnight.
What about picture-in-picture?
A separate but related feature is picture-in-picture, where video keeps playing in a small floating window while you use other apps, rather than the screen going black with audio only. On iPhone, true picture-in-picture for YouTube in the free app is inconsistent and mostly disabled; it works on Premium, and via the Safari method you sometimes get a native iOS picture-in-picture prompt appear automatically when you swipe to the home screen, a small floating box at the bottom of your screen that you can drag around or close. It's not guaranteed and depends on the iOS version you're running.
Third-party apps: a quick word of caution
You'll find App Store listings and TestFlight links promising free background YouTube playback through unofficial apps. I'd steer clear. Most either break after a few weeks when Apple or Google catches on, or they ask for permissions far beyond what a video player needs, things like contacts access or background location, which is a red flag for an app that only needs to play sound. If an app's business model depends on bypassing another company's deliberate paywall, ask yourself how it's making money, because it's rarely from goodwill.

Battery and data considerations worth knowing
Background audio from video, whether through Premium or the Safari method, uses more battery than a dedicated podcast app because YouTube is still decoding video frames even if you can't see them, it just isn't rendering them to the screen. Over an hour of background YouTube audio you might see 8 to 12 percent battery drain on a typical iPhone, compared to roughly 3 to 5 percent for a pure audio app playing the same length of content. If you're regularly listening to long-form YouTube content in the background, downloading the audio separately or switching to the equivalent podcast if one exists will be kinder to your battery and your mobile data if you're not on wifi.
Why this matters beyond iPhone convenience
If you create content yourself, it's worth understanding how platforms gate behaviour like this because it shapes what audiences expect and tolerate. The same logic that keeps YouTube's background play behind a paywall is at play when Twitter videos keep playing in the background on some setups and not others, or when Instagram Reels randomly stop playing mid-scroll. None of these are random glitches, they're product decisions with a commercial reason behind them, and knowing that saves you a lot of time hunting for settings that were never there to find.
If you're building your own channel rather than just consuming, it's also worth getting the basics right elsewhere, like making sure your channel banner dimensions are correct so your page doesn't look amateur, or checking why a new upload might be stuck at zero views before you panic and assume something's broken.
Which option should you pick
If you watch or listen to YouTube daily, for work research, podcasts, music, or background noise while you do admin, pay for Premium. It's reliable, it removes ads, and the monthly cost is less than a couple of coffees. If you only need background play occasionally, the Safari method is free and works often enough to be worth knowing, just don't rely on it for anything time-sensitive like a live stream you can't afford to miss. And if you're testing either method for the first time, do it on a video you don't mind restarting, not the one meeting or interview you need to hear in full.
Frequently asked questions
Does YouTube background play work for free without Premium?
Not through the official app. The reliable free route is opening youtube.com in Safari, requesting the desktop site, and locking your phone, though this can stop working after YouTube updates and isn't guaranteed to last.
Why does YouTube pause when I lock my iPhone?
Because the app is deliberately coded to stop background playback for free accounts, this is a commercial decision to encourage people to subscribe to YouTube Premium rather than a technical limitation of the iPhone itself.
Does YouTube Premium work for background play on iPhone?
Yes, once subscribed, locking your phone or switching apps keeps both audio and a floating video player active, and it also removes ads and adds offline downloads and YouTube Music Premium.
Is using the Safari workaround against YouTube's rules?
It isn't illegal and doesn't breach any law, but it goes against YouTube's intended free-tier behaviour, which is why Google periodically updates its systems in ways that make the workaround less reliable over time.
