So, I don't remember reading this on MR yet, but with 2.8.1, I now get a pop-up warning at 10% which I have to click okay to. So good news, more warning about the battery almost run out, you don't have to rely on your eyes noticing the message at the top of the screen.
I remember a lot of people complaining about the lack of warning, so I'm surprised I didn't see it mentioned, but maybe I just missed it. I haven't been letting my glo run completely down lately, so this was the first I've seen of it, even though I got this firmware very early.
Anyway, nice improvement
