IMHO the new "App Optimization" does its job. I couldn't find much differences in battery performance versus greenify. It just works.
Hmmm, my main concern is that the only option available is 3/5/7 days of delay before hibernating apps.
My typical usage scenario is that for some apps I don't want them to be hibernated at all (this is fine, I can uncheck the option for them) while for others I'd prefer them to be hibernated within minutes after I stop using them.
XDA Developers was founded by developers, for developers. It is now a valuable resource for people who want to make the most of their mobile devices, from customizing the look and feel to adding new functionality. Are you a developer?
