I have this problem as well. However, I only have it on one TV, and it isn't the one I watch most frequently. Therefore I don't believe these solutions would apply in my case.
I have 4 Roku remotes and 2 have the exact same battery draining issue that is well known. Batteries last about a week regardless of use. How can this been corrected? @RokuEuniceL Roku support - Please contact me. Thanks.
