I know that sleep vs power-off is a highly contentious topic on mobileread. I work purely on results and adopting a power-off strategy definitely extends the battery life for me - much more on the old touch than the new. I originally got involved in these general power discussions because of an observation that occasionally the old Touch would fail to slip from sleep-mode into full power-off mode and when this manifested it would chew through the battery power at an alarming rate. This bug aside, I believe the current poor life in newer machines is down to a bug with power management in the chosen linux kernel for the NEW touch/Glo (the old Touch was for the most part well-behaved).
Suspicions aren't enough of course. The only way we as users are going to know with any certainty is
a) Kobo admits to a problem (more chance of the Pope advocating condoms) b) have a reasonable sized group of us agree to a common testing regime in which both affected parties and non-affected parties with Touches and Glos adopt a common set of settings and test on free epubs. This should at least prove or disprove whether the hardware is at fault.
The biggest problem with b) is finding a statistically significant number of people (especially those unaffected) willing to give up the two weeks or so (2 tests - good settings/bad settings) necessary to do this. End result =
