Should MAX power saving mode from samsung phone implement on MIUI 10

Not needed, if someone really want to save some juice, without limiting function, it will use tasker...for start i suggest to create profile that use cell towers id for wifi on-off, and auto bluetooth off if there is no connection for eg 10minutes(in all day situation, that will save more juice than samsung ultra mega saver), and also with tasker you can implement all of that samsung stuff...
