I updated my device to Lineahe OS based on Android 15 after I have been using Lineage OS based on Android 14 for a while. I don't know if this is a common issue with Android 15 or it's only with Lineage OS or my installation is sonewhat crippled (I did clean flash and I already reinstalled once), but the OS is very aggressively killing apps compared to Android 14 to the point it is annoying.

Example

In Android 14 if I started a download in the browser, the browser would display a permanent notification that it's downloading and if I swiped away the browser from recents the download would continue. In Android 15 the downloading stops immidiately after I swipe the browser from recents.

And that's not the only problem. Background services like my companion watch app don't work properly because it seems they get killed in the background and messaging or e-mail apps sometimes seem to have the same problem. I tried disabling battery optimizations for these apps, but it doesn't seem to help at all.

Does anyone else experience similar issues with Android 15?

why would swiping away an app not kill it? why would you do that? leave it be until it's done wtf

how much RAM you got? on my two A15 phones with 6 and 8 GB RAM nothing extraordinary happens in that regard, whereas my A15 4 GB RAM tablet can't handle a lot of open apps and OOM kills some in the background.

EDIT: I tested the same with my file explorer while moving files, but the task didn't get killed. This might jusz be issue with the browser.

All the stock Android versions I used until Android did not kill tasks that are run with a persistent notification. Swiping away killed the app activity, but it did not stop its tasks or services.

My device has 6GB RAM and I never had such behavior.
