Furthermore when this occurs and I flick the power switch back on I notice a fair chunk of battery reserve has been eaten up. e.g. Enter sleep mode at 1 a.m. with 94% battery. Resume 7 hours later at 8 a.m. with 67% battery! It's almost as if the machine enters some kind of loop which chews through more power than if it was in true sleep or power off mode. Anyhow the net result is the same: I end up charging every few days if this happens. ... Has anyone else seen this behaviour?

Hi! I had similar problems with poor battery life in my Kobo Touch (purchased in Austria in October last year) after installing firmware 2.3.1.
I managed to solve that problem with simple solution - I turned off automatic Sleep & Power (set to 'Never'), and Screensaver also. After that, my battery lasted some two weeks with at least two hours of reading per day. E-reader was constantly in power-on mode.
Three days ago I installed firmware 2.4.0. Now, it seems to me the battery life is much better now with automatic Sleep & Power turned on, but I need more time & testing to be sure...
