We don't suspend while reading. Nickel does. There's (part of) your page-turn speed trade-off
.
(I am somewhat vehemently *against* implementing something like that, because I *like* that behavior. That said, the framework is there, because it's implemented on PocketBook. This is possibly a fairly deep rabbit hole with a lot of potentially bad interactions, though, but patches welcome
).
That said, that still sounds like a much more significant delta than it ought to be (despite what I said above, I usually don't notice a significant difference. Then again, I haven't read in Nickel in quite a while now).
And, yeah, don't trust the battery gauge. Like, at all.
