I have lastest firmware (aura one) and sometimes when I put it in sleep mode (manually because I have not a cover) the light do not turn off.
I have all turned off (wi fi, sensors) light is about at 13% of light power, and the battery drained from 100 to 33 % after about 100 pages of reading. But maybe this is because it was the first charge (I bought it last week).

I wisk anyway kobo can read this and do something to help the battery life in the next firmware. for example why do not to "undervolt" the CPU? maybe you can insert an "eco" mode that undervolt the CPU from 1000mhz to 500mhz and see if it helps with battery charge. All I need sometimes is to turn the page, I believe it's possible even with less powerful CPU. maybe you can force normal mode (1000mhz to automatically turn ON when people are using the Store App, or something that really need more power).
