Both the Fire TV and upcoming Fire TV Stick enter a sleep mode after being idle for 30 minutes. The Fire TV Stick will include an option missing from the Fire TV which allows you to manually force the device to sleep. The option is a bit buried in the Settings > System menu, so it’s not the most convenient thing to enable. Perhaps we’ll be able to uncover a remote button combination that can trigger this new action, much like the button combination that restarts the Fire TV. No word on whether this option will make it’s way to the Fire TV, but I suspect we’ll see a new software update shortly that adds this and Prime Music to the Fire TV Stick’s big brother.
