A few weeks ago my Roku Ultimate remote just started burning through batteries. I have another Ultimate that uses the same kind of batteries and I haven't had any issues with the remote for that Roku. Here is the faulty Roku information:
Software: 9.1.0 build 4111-29
Device ID: 7KA6A3986941
I'm currently testing behavior issues, but I'm pretty certain that's not causing it. The remote gets put into a basket while being watched as well as for the night. Same behavior before this issue started. Currently double checking my warranty to see if I'm still inside the limit. Any troubleshooting info anyone has would be fantastic.
