Fix to “Apps disconnecting from Chromecast (YouTube, Netflix, etc)”

As we mentioned at the start of this post, mostly new phone owners face this issue. The phones like Galaxy Note 8, Note 9, Galaxy S9, S9+, and others especially have this problem. Its root cause is the battery saving feature.

Phone manufacturers like Samsung, Huawei, etc are adding battery saving features to prolong the battery lives. Since there are so many battery-draining apps, high DPI screens, and backend services, it does help a little.

The battery-saving feature regulates the usage of all apps on phone. If any particular is running in the background and using battery more than the safe limit, then it automatically kills that app. Therefore, when users cast YouTube, Netflix, Hulu, or similar apps on Chromecast, they are automatically killed in the background by battery saver. Even if the app does not close, their on-going connection with Chromecast is cut.

To fix this issue, follow these steps:

  • Open Settings and head into the battery menu.fix apps disconnecting from chromecast 1
  • Now open the Battery Saver menu. fix apps disconnecting from chromecast 2

  1. I was hoping to fix the problem with the phone disconnecting to Chromecast when using the YouTube app so I wanted to add it to the unmonitored apps but it’s not even in the list so I can’t select it. I am using Samsung S7, running Android 8/Oreo with Dec. 2018 security update (Sweden). Is this just my phone or is there someone else out there with this problem?

    I know there are a lot of people having problems with YouTube/Chromecast since I found this post.

    • Hey,

      Some phones do not show system installed apps in unmonitored list. To solve this, just open advanced settings from menu button in top right corner (inside battery settings) and turn off “App power monitor”.

    • In addition to making sure the Home app is included on the list of unmonitored apps (Settings>Device Maintenance>Battery>Unmonitored Apps), make sure that Local Network and Security is unchecked (Settings>Lock Screen and Security>Secure Lock Settings>Local Network and Security).
