Kobo Remote causing high battery drain

We shall see how it works in practice after Christmas as I believe Santa is bringing me a remote.

Strange, when I turn off wifi and bluetooth with the OS shortcuts, and then turn on bluetooth with nickelmenu, wifi doesn't turn back on. Bluetooth turns off when sleeping and when I turn it back on with nickelmenu, wifi doesn't turn on.
I been doing this way for several days now, and wifi hasn't turned on at all even if I reboot.
My battery life is still great using the remote 3-4 hrs a day.

I got the remote for Christmas as anticipated. Last night in bed I read for an hour and a half using the Clara BW. Once I enabled the Bluetooth, I turned off WIFI. The front light was around 25%. Total drain in an hour and a half was 2%.

Not sure I trust the battery monitor with the software update on my Clara BW. Thought I was getting little drain with remote and wifi off. On 2 separate occasions now on restart monitor has jumped from 90 to 55%.

Losing over 10% per hour on a Libra 2 with the remote with wifi turned off. Also noticing the remote not registering button presses pretty regularly.

Exactly my experience — including the failure to register button presses; for me, it's roughly every tenth press that doesn't register (although there's no pattern to it). I've checked to see if the failure to register occurs when NickelClock is changing to a new minute, but there is no correlation.

I just noticed that whenever the button press fails the blue light on the back of the remote is on. Possibly the connection is dropping and reconnecting and the button press fails in between.

I went to the Kobo site and chatted with support. They escalated the issue.

I wonder how it works with a logitech unifying dongle attached with an otg cable, and a logitech device.

I would think it would not work.

Yes, you are exactly right! When paired with my Kobo Libra 2, every 30 seconds or so, the remote's blue bottom light comes on for two or three seconds, and during that time, presses of the page-turn buttons on the remote have no effect.

I did not have this problem when previously testing the remote with a Kobo Clara 2e. I will continue to investigate.

It sounds like perhaps since the Libra 2 has an older chipset, Kobo is using more aggressive power management to try to save battery life, and that's causing the connection to drop and thus miss some button presses.
