He's saying that it still tries to output to the headphones even though they aren't plugged in. And even if they were plugged in, there's no reason the battery should die if nothing is being played. It's just bad design all around by Roku, and apparently non-existent QA.
You make a good point. I have wondered why on earth the roku battery compartment wasn't designed like the xbox 360 controller is. Now let me explain to those who think a battery compartment is a battery compartment. They all do the same thing. Well No.. They can simply be, like your smoke alarm, a hole you shove batteries in. This is what roku has done. Now to get the batteries out, requires a pull ribbon, or you bang it against something to make the batteries fall out. This idea works when the batteries are good for months. Not when you need to replace them.
Now the xbox 360 controllers. They have a battery compartment that is a hole too. But the battery cover, has little slots to contain the batteries in. As you pop open the cover the batteries come out with zero effort. This means you can easily open it, and do this in a sleepy state playing late night games and kill the controller sucking juice. The beauty of this design is it lets you also use a rechargeable battery pack. One of the things I have always thought odd about roku. Why isn't it partnered with a battery supplier? It obviously is because in the roku comes batteries.
But why not one which makes rechargeable batteries? Then design a charge base for that remote to go with the roku. Now sure, extra hardware extra cost. But the convenience alone and the ease of use would put this model as the ultra. When do we get ultras with rechargeable remotes and charge bases? Soon? Can we get QI charging on the remotes maybe once we get rechargeable batteries? Then you just set the roku remote on the roku mat, and it charges with no wires. Make the charge mat round and purple with the little roku shirt tag hanging off the side. So cute. Everybody would buy one. Most would buy two. Are we there yet? I wish.. lol
