Apps Not Running in the Background on Android? Here’s How to Fix It

Every so often, some of you contact our support team because 4K Video Downloader for Android is not running in the background when you minimise the application window or exit the app. This happens owing to the Android smartphone settings, or more specifically when the default battery optimisation is on. Apps that continuously run in the background can drain the battery quickly, so Android tries to strike a balance between functionality and battery preservation.

Android uses a priority system to manage background tasks. Apps that provide critical functions like messaging, alarms, or location tracking may be allowed to run in the background more freely than non-essential apps. This prioritisation helps ensure that important background tasks can continue to operate.

In this article, we’ll show you how to turn off the settings that block the background run of Android apps, the Android version of 4K Video Downloader included.

1. Go to Settings -> Developer options.
2. Tap Advanced -> Background process limit.
3. Disable the background process limit (you can find it near the end of the list). If you don’t have the option to disable it on your smartphone, choose Standard or the biggest limit set in the settings.

However, we recommend using the battery optimisation ways.
