Update to post #25:
You may recall after 12 hours sleeping my fully-charged "new" touch (Glo software) the battery was down to 91% indicated. Since post #25 I've only had a chance for one 30 min reading session at 0830 on Feb 11th (+42 hours) when the battery was down to indicated 67%. Now tonight (2200 on Feb 12th) when I checked, my touch was showing the "Please recharge ereader" screen. Unfortunately I can't say when this happened precisely. In truth it could have been anytime after 0900 Feb 11th but let's be generous and say it happened just before I checked it. This means for a total reading time of 40 minutes plus an outside maximum of 112 hours in sleep, the unit is dead!
So how's my father's (old) touch faring? Well I didn't set that up until 14 hours after mine but at 98 hours in sleep (waking it up only once a day to check status) it's still showing 91% battery indicated. This is consistent with what Mrs_Often is seeing between her old Touch and her new Glo. I would say that's a pretty big smoking gun for a power problem in sleep mode in Glo/Latest Touch firmware!
Now bearing in mind the usual power profile selected for both machines is 15 Min sleep/ 30 Min power off, I have to re-iterate that I've seen battery chewing happen on the old style Touch's on 1.9.17 as well as newer firmwares on occasion (which prompted my first posting) but it was unpredictable in that I couldn't trigger it on demand. All I did note was that the device failed to enter power-off when this happened. However, it seems that just sleeping it isn't enough to trigger the massive power drain as tests on my fathers unit have shown thus far. Whether this condition is related or not (it seems likely) I can say that there is most definitely an issue with the newer firmware Touch/Glo's when in sleep mode that is reproducible.
Anyone from Kobo care to comment?
