Power off vs. Sleep
The Kobo Touch ships with default settings of sleep after 15 minutes and to never power off. Is there any downside to not turning it off, just putting it to sleep? Are these the preferred settings?

this is actually been mentioned a couple of times; when in sleep mode , the last page you are on stays in the systems ram, which requires power to maintain, and this is why it's much faster to get back into your book from a sleep state. When the device is off, ram is cleared so no power is required to maintain it. There is however, I believe, constant power drain regardless of the power state for the system clock, but this should be negligible.

I've had my KT for a couple of weeks now and have only used the default settings. I don't notice a great battery drain when it sits idle and will probably leave those settings and only turn it off when I know I won't be using my Kobo Touch for number of days.

My Kobo Wi-Fi lasts 40 days using power off and lasts 11 days using sleep mode, reading once a day for 2 hours.

I once had auto off after 1 hour set. Seemed I was often turning it on soon after auto off so no power saved.

Battery savings mainly as many have said.
if i only "sleep" and never power down, i'll get a weeks reading out of a charge. If i power off between uses, Easily 2-3 weeks |

Bottom line is; don't use sleep mode. It may be convenient, but it sucks the life out of your battery. |

I started using sleep mode two days ago, after recharging my battery. Powered off only in the evening. After approximately 6-8 hours of reading, my battery died. The monitor was showing it was approximately 3/4 full. Charged it overnight for about 11 hours. This morning, it still said it was connected and charginig. After disconnecting, it looked fully charged. I am running 1.9.9

I leave mine on sleep all day, it's a bit of pain turning on and loading the book I'm reading. Of course this might change if I got a KT because the start up speed is so much faster. But also remember that turning it one will take up a bit of power as well.

Sleep mode on the Kobo is not nearly as power efficient as Kobo seems to think. I can only compare to my other e-reader, the Sony PRS-650. That one can go a month on a single battery charge with sporadic daily reading in sleep mode.. The KT, oth, needs to be powered off or it will barely go over a week. It doesn't help that the Battery meter on the KT is so unreliable. (At best, the unit will force shutdown when the battey is still at a quarter.)
