That FF/REW feature has been in there since the first models xD
Also I think the kind of full shut down is like 12hrs of no use or button pressing. Since it is really doing nothing on stand by I'd be surprised if you would notice the difference in power consumption. I don't think you'd be saving an extra hour of music by making it less, in fact you'd probably be churning more power having to reload the ram with data.
Today my A17 rebooted itself from nothing, was listening to some FLAC files and it shutdowna d rebooted, rebuilt the lib again and then I proceeded to play the same flac i was listening before and all went normally as nothing had happened
is the first time I noted this behaviour on my A10, reminded of conatnt reboots of my ex-fiio-x3
