> One problematic issue I can see the Pinephone have in regards to this is that there's no unified push service that works for all apps.

I don't think that's the problem. It would not be that hard to have system-wide settings to control which applications can apply for background updates.

My (limited) understanding is that the difficulty resides in hardware support for sleep/low-power and the many different implementations from every hardware vendor. Note that it's also a problem on desktops/laptops (with S3 and related techs) even on Windows using official firmware/drivers.

If you have more detailed reads, please share :)
