Thank you for letting us know about the remote battery drain issue you are experiencing with Streaming Sticks+ (3810). Our engineering team has been investigating this issue closely and once more information is available I'll be sure to let the Community know.
In the meantime, if you are powering your Streaming Stick through the USB port on your TV, we would recommend that you power your Roku device through a wall outlet to see if that helps the issue you are experiencing.
Danny I am having the same issues with battery replacement in my remotes after 4 days. I have tried powering via usb on my tv and the plug in adapter supplied in the kit and I have the same battery draining issues. I tried taking out the batteries between uses and that gives me an extra day of usage.
My Roku Streaming Stick + remote battery is drained every time I use it. When I turn on my Roku the batteries in the remote are dead. I'll pop in fresh batteries, use it once, and then on the next use the batteries are dead again. I use the Roku stick with a projector. When I'm using it I have it plugged into the wall, but at other times I have the projector and Roku stick stowed away. Leaving the Roku stick plugged in 24/7 is not an option. Please tell me you have other solutions in the works to fix the battery drain problem. Thank you.
