I am having same problem, I have the Roku Soundbar and its started to be every week now that I need to change batteries. It use to be every month which still was bad. I purchased it 4 months ago.I do not do heavy watching or use headphones or any other things that would account for this.
Troubleshooting has not worked, I've checked- powersource is into the wall, the remote software is most up to date. SN# 2C108D101397. To date I have not read any of the previous many posts regarding this issue and how to properly fix it. This is a wide spread problem and I know other users who have similar problems with their sticks including me who had a previous stick with battery issues but not as severe as this current product and just upgraded to the Soundbar system. Please advise, the batteries seem to be draining much faster after each change, it's now less than 1 week.
We appreciate your post regarding the remote battery drain issue you are experiencing.
Please send me a private message with your Roku account email address, and include the serial number of the Roku device from Settings>System>About along with a summary of the issue you are experiencing. I'll be able to assist you further from there.
