There is no fix for the problem of Roku's remotes using up batteries. By now, Roku's engineers -- whether employees or contractors -- must know exactly what the underlying issue(s) is/are. Hardware? Firmware? Both? Their apparent need to continue collecting serial numbers seems laughable at this point. There needs to be a formal public statement describing what's been going on with this long-standing problem that spans multiple generations of products.
Hi everybody, I had the same problem, wasn't willing to jump through hoops with Roku to get a replacement remote after seeing no luck on this thread. After I couldn't even get my Roku to respond at all (even with new batteries) RIGHT IN THE THE MIDDLE of the Packers game last week, I ordered an Amazon Fire stick (only $25 on sale!) and so far am very happy after ditching Roku. I recommend the same to all of you!
