My GL4e is getting close to where I need to charge it, so I figured I'd share my battery stats (from KOReader). Meant to do this before the last charge, but I totally forgot.

I've read/made progress on three separate books during this charge. At a very rough estimate, I'd guess that it's been around 1000 pages or so. Now that I'm typing this up, I kind of wish that KOReader included the number of page turns in the battery stats.
This is on my Nook GL4e. My frontlight, wifi, and bluetooth are all always turned off. I only use KOReader (and pretty much never even exit out of the app). I have that energy saving patch enabled and my Nook is rooted (with Kernel Adiutor installed in order to set CPU as interactive). Other than that, I have very few other apps installed (mLauncher, Magisk, KOReader, Kernel Adiutor).
Overall, I'm decently happy with this battery life. I still feel like it was better on my old Nooks, but I tend to get about two weeks out of a charge and that's not too bad for me.
