I see a test report posted on ReaderRocket that the Aura supposedly has a much shorter battery life than the Glo when using the glow light. They claim Aura 28 hr. versus Glo 55 hr. (source: "real world tests").

This one says Aura 30 hr. versus Glo 70 hr., but no source is given, so they are probably copying and combining the Glo spec with some other source about the Aura (maybe just rounding up the ReaderRocket number).

Kobo's spec for battery life for the Glo says "Over 1 month" and "Up to 70 hours of continuous usage with ComfortLight on". For the Aura it says "Up to 2 months" and nothing about the light.

In theory the battery on the Aura is supposed to have 2x more capacity, right? And one of the reasons for that was to support a longer life with the light on, right? I find it hard to believe that it takes a lot more LED power to light a 6.8" screen than it does to light a 6" screen, so what's up with these numbers? Is it just one test improperly conducted? Has anyone actually tested the battery life of the Aura with the light on? At what level setting? (no level specified for any of these specs or test reports)

My personal sense so far is that the Aura does last longer than the Touch with the light off most of the time, but it does drain noticeably quicker if the light is used a lot. But faster than the Glo?
