Is it even possible to fully turn off a Kindle anymore? I want to do exactly what you’re saying to prevent the draining of the battery, but the only options that appear after holding the power button are “Cancel” “Restart” and “Screen Off”. Holding the power button longer just seems to restart the device :/

I they need them always on so that they can gather up data from Amazon smart TVs that were never connected to the internet (project Sidewalk).

Kindles have an airplane mode. I use mine only for sideloading so it hasn't connected to the internet in years.
