Minimizing battery usage

Pajamaman · 05-26-2026, 03:56 PM

I have a Kobo Sage and I want to use Koreader. Unfortunately the Sage battery is very weak and I have read Koreader will use more battery than the inbuilt nickel UI.

Koreader contains a lot of menu options I will not need. I want to switch those off. Hopefully that will remove battery usage. How do I remove them, and do you know any ways I can reduce Koboreader battery usage?

I posted some time ago about extending battery cycles on the Sage by using a different governor. I'm a bit surprised that the post didn't get any interest. I guess people prefer waging troll wars over button positions.

While it does seem to extend battery cycles somewhat, it cannot fundamentally change the fact that the Sage CPU power management simply is not very good. Part of the problem is that it also seems to burn quite a bit of battery while suspended.

As for turning off stuff you don't need, sure. To me an ebook reader is a single purpose device, so I don't really want any of those new vibe-coded "features" and addons.

Pretty much anything that doesn't directly contribute to the reading function. But, yes, I probably should have left that part out.
