But, for battery info, it isn't important as I tested (or better said, used) all my devices in pretty much the same way, even if days may be a bit different (no two days in our life are same), it is same software, similar reading practices, times, etc.
Even if nickel has a bit better battery economy than koreader, it doesn't matter, on H2O you'll still get about double battery life than from KA1.
It may be important info for someone who wants to know which software manages battery in better way, koreader or nickel, but for same user who uses same software on each devices, this point is mute.
And yes, from what I know, nickel does manages battery a bit better, so you maybe would get 5-10% more reading time on nickel if you read really a lot (3-10 hours per day). With hour or less, it is maybe 1-2%. These percentage is my estimate, not something I actually tested, as I never use nickel, but I know that it does has some better battery management (nickel after about 7 seconds turns everything and leaves only IR grid and needed system to wake device. 7 seconds is needed to render next page. I don't know how it works with devices without IR grid, it may have same system. H2O has IR, KA1 doesn't).

This assumes that the (potential) inefficiency of koreader doesn't get exponentially worse on a bigger screen/with KA1 hardware. This may be irrelevant to you personally, but without rigorous testing, asserting that KA1 battery is half as good as the H2O is just bad science. Especially as many users only use nickel and may care tuppence about how it performs with koreader.
What it really boils down to is, while it is perfectly helpful for you to say your usage, and your experience, it is not very helpful to widely proclaim that someone else who might have a more typical usage is plain wrong (your earlier post # 105), especially without saying the caveat that you use koreader, so your experience may be weighted/biased.
