Hi there, thanks for your feedback. We want to make sure that our battery life is great for all of our customers and three days of battery is not considered normal behavior.
Customers who utilize the private listening feature will typically receive a shorter battery life on their remote. As a tip, always be sure that you are unplugging your headphones when not in use as this will help to extend your batteries life between charges.
However, if this does not resolve your concern, we hope that you'll reach out to us so that we can assist you directly. Visit support.roku.com/contactus to get started chatting with an agent.
