I've just disabled this on my ATV4K and will see if it makes a difference. I have had to charge my remote about once a week.I'll put this info here, but unsure if the issues are the same.
I had a similar issue with my ATV4 when I first got them, and it ended up being the Channels app's "shake to mute" feature which allows you to shake the Siri remote to mute the audio. This caused battery draining on the remote where I would have to charge it a once week or so. I've since disabled the feature and everything has been fine since with my ATV4s and ATV4K.
