Yes. It has a high degree of control for that. I use many of these features; am running stock 7.1.1 Nougat on a 64GB Nexus 6P.
I am very curious to find alternatives to Samsung's SmartManager.
BTW I am not talking about the "Data Saver" feature. I am talking about iOS-level of disallowing apps in the background -- they are killed and not allowed to run a single millisecond on the CPU, no questions asked. The "Data Saver" is a very minor and niche improvement.
