On a Samsung Galaxy phone, set Larix Broadcaster’s battery usage to Unrestricted if that option is available, add Larix to Never sleeping apps, and leave Power saving off while you stream. These steps reduce avoidable background restrictions; they cannot ensure an uninterrupted 24/7 broadcast.
Samsung menu names and routes vary by model, Android release, One UI version, and region. Use the paths below as starting points, then check the settings on the exact phone you intend to use.
Why Samsung battery settings matter
A phone treats an app in the background differently from one you are actively using. Battery management can limit background work, and Samsung can also put infrequently used apps into sleeping or deep sleeping states. If Larix is sending a live feed while the screen is off, either kind of restriction may interfere with the app continuing to run.
There are three separate controls to understand. Android’s per-app battery mode governs how freely an app may work in the background. Samsung’s sleeping-app list determines whether its own app management may put that app to sleep. Power saving is a broader device mode that Samsung says restricts background access to Wi-Fi and mobile data. Changing one does not necessarily change the others.
For a short test while you watch the phone, a restriction may not be obvious. It matters more when you lock the screen and leave the phone alone for hours. A devotional channel running overnight, for example, needs the phone to keep Larix active and connected after you stop touching it. Battery settings are a sensible first check, not a substitute for testing the stream itself.
Samsung’s battery optimisation guidance describes the Never sleeping apps list, Power saving effects, and factors that affect battery use. Samsung notes that the article is based on Android 13 and that names or entry points can vary. Its developer documentation on application management also describes how Galaxy devices may manage sleeping apps. Treat either page as a reference, not a guarantee that your menus will look identical.
Set Larix battery usage to Unrestricted
Open Settings and look for Larix Broadcaster’s app information or battery settings. Samsung’s Android 12 / One UI 4.0 support article documents this route: Settings → Applications → select the app → Battery → Unrestricted. On a newer phone, the starting point or labels may differ; searching Settings for “Larix” or “battery” can be quicker than following an older route exactly.
If you find a choice among Unrestricted, Optimized, and Restricted, choose Unrestricted for Larix while testing a continuous stream. Android describes Unrestricted as allowing background work with potentially higher battery use. Optimized applies background limits based on factors such as your interaction with the app, while Restricted can prevent background execution. The point is to avoid asking the phone to conserve power by limiting the app that is responsible for sending the stream.
This setting has a cost: Larix may use more battery while it is allowed to remain active. If you are testing on battery, watch the charge level and temperature rather than assuming Unrestricted is free of trade-offs. For a long session, plan the power arrangement using the requirements of your particular phone and charger; no setting here establishes that a charger, cable, or phone will remain suitable for every environment.
If “Unrestricted” is not shown, do not assume a similarly named choice has the same effect. Check Samsung’s current support information for your software version, or search the phone’s Settings for the app-specific battery controls. Google’s Android background optimisation documentation explains the general distinction among these modes, but Samsung’s interface may present them differently.
After changing the mode, return to Larix and make a brief test broadcast. Confirm that the app still shows the expected connection and that YouTube receives the feed. Then lock the screen and check again after a meaningful interval. This tests more than the menu: it checks the behaviour of the phone, app release, and network you will actually use.
Add Larix to Never sleeping apps
Samsung’s automatic app management is separate from Android’s per-app battery mode. A device may decide that an app is not used often and move it into a sleeping category. Samsung provides an exception list called Never sleeping apps, intended for apps you do not want the phone to put to sleep automatically.
A documented Samsung route is Settings → Battery and device care (or Device care) → Battery → Background usage limits → Never sleeping apps → + → select Larix → Add. Depending on the phone and software, you may find a different label or sequence. Search Settings for “Never sleeping apps” if the route does not match, and confirm that Larix appears in the list when you finish.
This exception addresses Samsung’s sleeping-app management; it is not the same as setting Larix to Unrestricted. If you only add the exception, Android’s app battery mode may still be Optimized or Restricted. If you only choose Unrestricted, Samsung’s separate sleeping-app policy may still be relevant. For a deliberate test, check both controls rather than treating either one as a master switch.
Samsung’s support instructions explain how to add an app to the exception list, while its developer material describes sleeping and deep sleeping app behaviour. Those sources establish the purpose of the setting, not that every Galaxy model uses the same menu or that the exception overrides every other limit. Check the live phone after making the change.
Keep the list purposeful. The exception is useful for an app that must remain available in the background, but it also means the phone is less likely to put that app to sleep to save power. If Larix is only used occasionally, you can revisit the choice when you no longer need it for a long stream.
Keep Power saving off while streaming
Switch Power saving off before starting a continuous broadcast, then verify it has not been enabled by another battery routine or quick-settings action. Samsung says Power saving restricts background app access to Wi-Fi and mobile data. That conflicts with what Larix needs when it is sending a feed after you lock the screen.
The exact effects and controls can vary, so read the description shown on your device. Do not infer from the name alone that Power saving only dims the display. If it restricts background data, a stream can lose connectivity even while the app remains open in the background. An Unrestricted app setting does not necessarily cancel a broader device-level data restriction.
Power saving may be useful when you need to extend the phone’s battery life for ordinary use. For a long live session, however, conserving charge by limiting the app’s background network access works against the task. Decide which need takes priority for the session, and check the mode again before leaving the phone unattended.
Reducing unnecessary display use can help manage drain without relying on Power saving. Samsung identifies screen brightness, time with the display on, high-resolution streaming, and enabled services such as location as battery-use factors. Lower brightness and turn off services Larix does not need, but do not disable capture, network, or other functions required for your setup. A darker screen can reduce display use; it cannot fix a weak Wi-Fi signal or prevent an app from being stopped for another reason.
For a phone-based stream, battery and heat deserve attention as well as background execution. Use a compatible charger and cable according to the phone’s charging requirements, and place the phone where it can be observed and ventilated. Avoid treating a particular charging accessory or a dimmed display as proof that a device can run safely or continuously in every condition.
Check the stream after locking the screen
A reliable check is a small rehearsal with the same phone, Larix configuration, network, and power arrangement you expect to use. Start a test broadcast, confirm that YouTube is receiving it, lock the screen, and leave the device untouched for a period that resembles the beginning of your planned session. Then check both the phone and the YouTube output. The purpose is to see whether the screen-off behaviour is acceptable before depending on it overnight.
Look for concrete signs rather than relying on one status indicator. Is Larix still open and showing a connection? Does YouTube continue to receive video and audio? Has the phone changed its battery mode, lost Wi-Fi, or displayed a warning? If the broadcast has stopped, note when and what the phone reported. A single successful test is useful evidence about that setup, but not a promise about future network or power conditions.
Larix’s maker, Softvelum, says in its Larix FAQ that the app works in the background until you explicitly close it. That describes the app’s intended background capability, including with the device locked; it does not certify a particular Galaxy model, software release, network, or 24/7 session. Keep the app open, and avoid swiping it away or using a device control that explicitly closes it.
If you run into trouble, check the simplest causes first: Larix’s app battery mode, the Never sleeping apps exception, Power saving, and whether the app was closed. Then check the network and power arrangements. A stable battery configuration cannot correct packet loss or a router dropping its connection.
For a file-based channel that does not need a phone camera or a mobile app, a different operating approach may be more practical. A 24/7 stream of recorded lessons has different choices around playback and captions than a phone-originated live feed. If you are comparing a computer-based loop, the Ubuntu cloud VM setup for YouTube streaming covers a separate route; it is not a fix for Larix settings on a Galaxy phone.
What these settings can and cannot fix
These settings reduce the chance that battery management will deliberately restrict Larix in the background. Unrestricted permits more background work, Never sleeping apps makes an exception to Samsung’s automatic sleeping list, and turning off Power saving avoids its documented background data restrictions. Together, they address specific phone-side causes worth checking before a long stream.
They do not ensure uninterrupted streaming. They cannot guarantee that a wireless network stays available, mobile service remains usable, the phone has sufficient power, YouTube accepts every part of the feed, or the app and operating system behave identically after an update. They also do not confirm that a particular Larix release meets every platform requirement on every device.
Samsung’s developer page notes that One UI 6 with Android 14 changed foreground-service expectations for apps targeting Android 14: those services are expected to work as intended when developed according to the newer foreground-service API policy. That is a platform condition, not evidence that a specific Larix release has a particular target SDK or that it is certified for your phone. Do not read a general platform note as confirmation about an app build.
Network problems need network checks. Softvelum’s FAQ notes that RTMP and RTSP can show frame loss when network conditions worsen and discusses SRT recovery within its configured latency period, as well as adaptive bitrate where conditions may be unreliable. A configured bitrate is a target, not a guarantee when connectivity degrades. Battery settings do not repair packet loss, and changing the phone’s background mode is not the same as adjusting the streaming protocol.
If you are diagnosing a failure, separate the questions: did Android or Samsung restrict Larix, did the network fail, did the phone lose power or become too warm, or did the receiving platform stop showing the feed? Record what happened and test one change at a time where practical. That makes the next adjustment more useful than changing several settings without knowing which one mattered.
If you need a stream to continue while your computer is off and do not want to rely on a phone staying open and connected, StreamNeo turns an uploaded video into a YouTube live stream and restarts it automatically if it drops. That addresses the specific burden of keeping a personal device running, but does not remove the need to prepare the file and YouTube channel or to check your stream.
For creators still using a local computer, keeping a playlist running when it ends is a separate playback issue. If your format involves scheduled material rather than one live phone feed, switching playlists during an ongoing loop covers another part of planning a continuous channel. Choose guidance for the actual failure point rather than expecting battery settings to solve every continuity problem.
Before committing, compare the operating options on the pricing page. When the file and channel are ready, start free — 24-hour trial, no card.
FAQ
Does Unrestricted stop Samsung from putting Larix to sleep?
It changes Larix’s per-app battery mode to allow background work, but Samsung’s Never sleeping apps list is a separate control. Check both settings if they are available on your phone. Neither setting guarantees that the stream will remain connected.
Can I leave Power saving on if Larix is Unrestricted?
Samsung says Power saving restricts background access to Wi-Fi and mobile data, so it can still conflict with a background stream. Leave it off during the broadcast and verify the phone’s displayed settings. The exact effects can differ by software version.
Will Larix keep streaming when I lock my Samsung screen?
Softvelum says Larix supports Android background operation until you explicitly close the app, including when the device is locked. Actual behaviour can still depend on the Galaxy model, software, app release, network, and power conditions. Test your own phone before relying on a long session.
Why did my stream stop after I changed these settings?
Battery settings address only some background restrictions. Check whether Larix was closed, Power saving was enabled, or Samsung still lists it among sleeping apps, then check Wi-Fi or mobile data and the phone’s power state. These checks can narrow down the cause, but do not guarantee that a future session will stay live.
