Will doesn't have Amethyst to have a good reference for battery drain.

What are your numbers on baterry usage with all that?

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.

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.
