So the issue is not Android (AOSP) provided by google, but OEMs ?
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.
Also, such apps are unloaded from time to time even on stock non-modified Androids.
