I own two 2nd gen nVidia Shield devices and I swear the batteries in the remote last about 3 weeks before I start getting "low battery" notifications.
My wife likes fake tea candles, cheap and flicker just like normal candles and use the same CR2032 button battery the shield remote uses. When she buys new batteries, they come in a box of 100, but are basically Amazon branded batteries.
Should I splurge $6-10 for name brand CR batteries? Or cut my loses and get some $15 replacement remote that uses cheap AAAs that I know will last for months?
Mine was the same. I turned off always listening and that helped. I now use a harmony remote and that remote sits in the drawer.
