I've collected some hacks from our kernel team and tested the idle time on battery on my Librem 5 Birch - got almost exactly 6 hours while staying at 38°C the whole time. Not that long ago it struggled to reach 3h and stay under 60°C - and they're not done yet! :D

That's with the screen, modem, WiFi and USB off. Modem probably wouldn't influence it that much though.

Oh, and that's of course on the 2000mAh battery. The final model is going to have a 3600mAh one :)

@dos Do you know where the majority of the power goes in idle?

@solarkraft Lots of various things were being tackled recently, like voltage scaling or GPU not turning off when unused. USB seems to be quite a power hog for some reason, and we still don't even suspend the CPU there.

I'm not an EE though, just a high-level software guy that likes to try all the new shiny unfinished stuff, so no idea on the details ;)

@dos Thanks for keeping us updated. Also for the informative comments over at reddit!
