Is Samsung aggressively killing backgrounds apps on Android 11?

Samsung has done a pretty amazing job in rolling out the Android 11-based One UI 3.x update to its smartphones and tablets. The new version of One UI brings various design improvements and new features to the devices. However, it might also be aggressively killing background apps on Galaxy devices.

The DontKillMyApp website, which lists brands that aggressively kill background apps on Android smartphones, has ranked Samsung at the top. The company has become the worst offender ever since it started rolling out the Android 11-based One UI 3.0 (and One UI 3.1) update to Galaxy devices. The company prevents apps from working in the background by default unless you exclude apps from battery optimizations.

If you've noticed that your Galaxy device is killing some important apps in the background, you can navigate to Settings » Apps and then click on the app you don't want to be killed in the background. Now, navigate to Optimize battery usage, find your app from the list, tap on it, and then click on Don’t optimize.

Google had mentioned last year that it is taking measures to address smartphone brands that are aggressively killing background apps, but it looks like the companies aren't following Google's lead. In our case, we have noticed some issues related to the WhatsApp app on the PC, with the app saying that it can't connect to our smartphone. However, we are unsure if it is related to Samsung's aggressive battery optimization techniques.

Have you noticed background apps getting killed on your Galaxy smartphone or tablet after the One UI 3.0 or One UI 3.1 update? Let us know in the comments section below.
