Without the problem for YOU, because, presumably, you have a non-shitty phone. It is a much more severe issue on the likes of Samsung / Xiaomi / Huawei. See https://dontkillmyapp.com
And if you force Google to stop verifying proper behaviour in CTS, do you expect those manufacturers to allow you to run background services at will?
They already kill off anything that's not whitelisted to keep those battery numbers up. The every new major OEM release we developers find bunch of new ways the try and kill background apps.
Also, such apps are unloaded from time to time even on stock non-modified Androids.
If you think people talk about AOSP when they talk about Android, you are always going to miss the point of these conversations.
> Unfortunately, vendors (e.g. Xiaomi, Huawei, OnePlus or even Samsung…) did not seem to catch that ball and they all have their own battery savers, usually very poorly written, saving battery only superficially, with side effects.
My apologies to NGRhodes, the link does indeed refer to an issue with OEM and not what Google supplies. I don’t really see what it has to do with the topic we were discussing however.
