How to Stop Android From Killing Apps in the Background

You queue up music in Spotify and make a call — when the call ends, the music has stopped. You set a navigation app and switch to another app briefly — when you return, navigation has restarted. Android’s background app management is designed to save battery but sometimes it goes too far. Here’s how to take back control.

Why Android Kills Background Apps

Android’s memory management aggressively kills background processes to free RAM for foreground apps and reduce battery drain. On stock Android this is fairly reasonable. On Samsung One UI, Xiaomi MIUI, and several other manufacturer skins, this behavior is significantly more aggressive — sometimes killing apps within minutes of you leaving them.

Remove Apps From Samsung’s Sleeping App List

On Samsung phones, this is the primary setting to change. Go to Settings > Battery > Background Usage Limits. Check Sleeping Apps and Deep Sleeping Apps. Remove any app you need to run in the background — navigation, music, fitness tracking, download managers. Apps in these lists get killed quickly when not in the foreground.

Disable Optimization for Specific Apps

Go to Settings > Apps > [App] > Battery and set it to Unrestricted. This tells Android’s battery optimizer to leave this specific app alone. Do this for apps that genuinely need to run continuously — navigation, music players, podcast apps, fitness trackers, and anything with background sync that matters to you.

Don’t Clear Recents to Close Apps

Many Android users have a habit of swiping away all apps in the Recent Apps view to ‘free up memory.’ This actually forces apps to restart from scratch next time you use them, which uses more battery and RAM than leaving them in the background. Modern Android manages memory efficiently without manual intervention — let it do its job.

Check Adaptive Battery Settings

Go to Settings > Battery > Adaptive Battery. While this feature is useful overall, it learns which apps you use and restricts ones you open infrequently. If it’s restricting an app you actually need, disable Adaptive Battery or set specific apps to Unrestricted to exempt them from the adaptive restrictions.

Use a Foreground Service for Critical Apps

Some apps allow you to enable a persistent notification that keeps them running as a foreground service. Spotify, Google Maps, and fitness apps all do this. A foreground service cannot be killed by the system. Look in the app’s settings for an option like ‘Keep App Running’ or ‘Foreground Mode.’ The tradeoff is a persistent notification, but that’s a small price for reliability.

Third-Party Brands: Specific Settings to Check

Xiaomi, Oppo, OnePlus, and Huawei devices each have their own aggressive background management systems with different names and locations. Check the dontkillmyapp.com website — it maintains a manufacturer-specific guide to exactly which settings to change on each brand’s phones to stop aggressive app killing.
