Hi,

finally the super-flexible lua/KOReader ecosystem allowed me to reproduce the Nook Glowlight 4 deep sleeping between page turns with a single patch.

The patch page with a detailed Readme is at https://github.com/Codereamp/nopowen

Basically this patch sends the Nook into Deep Sleep after every page turn. So, a short period of wakefulness for preparing and showing a new page is followed by the longer one until you consume the page and decide to go to the next. This translates into about 3000+ page turns on a single charge, but the real number may be different depending on other operations and your habits.

My previous attempts was to find what's wrong with not sleeping, an attempt to make a cross-app solution (but it required an advanced preparation and root). The KOReader patch doesn't require root and needs only a couple
of simple actions and probably of reading a not-so-long readme

If you have any questions, and issues, please, post them here.

Thanks
