At first I was impressed that my battery usage is less than 1% but now I realize that Pokey has been stopping and not showing me notifications all day long, even though it is running.

I noticed that in Graphene, if you switch users sometimed it does not connect again to the relays when you are back. Is it possible that was your case? Maybe same situation will happen if the phone was turned off.

Did you disable battery optimizations for Pokey? It should be set to "Unrestricted" to keep it from being closed or deactivated by Android's regular device optimizations.

My Pokey is pulling less than 0.1% of battery usage. I comparison, Amethyst is pulling 1.4%. So Pokey's battery useage has been very good for me. I suspect its battery useage is dependant on how many notifications a user receives over time, but generally speaking it appears to be very efficient.
