Update on this/Closing the loop:
Firmware has made battery life better. I have not dealt with a single drop-off in signal or device becoming unresponsive while still being on. This mouse is something that I won but was plagued with the above issues from the day I got it. While I did not reach out to Glorious Support about this, I did ask them directly about their thoughts with performance. While I do not think anyone is wrong here or that this issue was the norm, I knew it would be some time before it was fixed. For the outliers who had this issue, we have a solution.
This is where I wanted the hardware to be when I asked the question before in the O2 Pro AMA
I am now Pro for the Pro. I am more Pro for a Series One Pro 4K/8K with This. Exact. Performance. Please and thank you.

Thanks, Glorious!
