The best pdf reader for me is Okular. It is free, open source and certified with the German "Blauer Engel" for it's energy efficiency (as first software ever btw)
I don't think it's more "power efficient" than other pdf readers (Like Sumatra). It looks like the only reason it got that award is because it's German software. I'm saying that as Austrian. Super weird thing to give an award to.
How would they even measure it? Pdf readers use close to zero CPU. And using more or less RAM has nothing to do with power usage.
I would bet a million that Adobe is very resource heavy in comparison to Okular. So while it is using almost nothing, everything adds up
Yes and no, the people making Okular likely applied because they are German, they got the award because they applied for it, and met the Award criteria. The award criteria seems to me fairly general in its approach to software testing, but resonably rigorous as well, the amount and type of measurements required also seem resonably useful for answering roughly the question: "Is the tested software energy and resource efficient", it can be found here
Presumably it means it has been actually audited by a third party for wasteful cycles, etc. It doesn't necessarily mean that it's cheaper to run than another app, just that it's cheaper than some objective standard.
Not advocating for the use of that software, but…very easy to measure.
Evince for me. I can print off pages from songbooks I have in e-book form. Evince don't care about no drm
Okular is awesome
I'm loving Librera these days. Full version is free on F-Droid.
