Something that doesn't get talked about as much is the differences between how manufacturers customize their OS. It has been talked about a fair bit on HN (https://dontkillmyapp.com/), but it really is a huge problem.

I can be listening to music on my phone and One+ will just kill Pandora, or Spotify. I have to manually "lock" music apps and workout apps in One+'s task switching UI to keep them from being randomly killed while in use.

Hilariously enough I have one game on my phone that will always run in the background and never be killed, sucking down a lot power. Somehow even when not in the foreground it consumes massive CPU. I don't think it is even malicious, just oddly programmed. I wish my music apps could pull off the same trick though!

I had a similar problem with my OP6T. My hike tracking app would constantly turn off randomly in the middle of a hike. Having used Android for years I went through all the typical battery optimization settings, but nothing worked. I contacted the app developer and they had no idea what was causing it.

Eventually I stumbled on the "Lock" feature, which as far as I know is specific to OP, and that solved everything. I'm pretty annoyed with OP about it to be honest. Android has app-specific battery optimization settings built in but they just completely ignored them.

I don't think a lot of people understand how apps run in the background on Android. I know having worked on one recently, coming from iOS, I had a lot of assumptions about what it would or wouldn't be doing... and they were all wrong (of course).

Turns out Android, at least however this app is setup, maybe by default, leaves the app fully running. Like zero effort to suspend it automatically. A part of the UI crashed and a hunt to find the bug made me realize this... I fixed the bug, but still haven't really looked into how to really suspend it.

It helps that each version does it differently, and the OEMs also make their own set of fine tuning.

You should try disabling deep battery optimization in Settings -> Battery -> Battery optimization -> Advanced optimization. Unfortunately that feature is known to cause these kind of problems on OnePlus devices.

I have a One+ and I can't really recommend Greenify (App) enough. Forces all apps to shutdown, even those running in the background.

I have plenty of memory, I don't want apps force closed.

If I switch from a game to a browser to look something up, being able to switch back to the (paused) game 5 minutes later is a feature, not a bug.

Apps that obey backgrounding and stop doing work (e.g. burning CPU/Power) are fine.

I've had a 1+1, 1+3, and 1+5, and I never had this issue on any of them.
