My suggestion would be to turn off the reader when it's not used instead of using sleep mode.
Almost an hour I was writing here my weekend testing experience and when I want to post I am "not logged in" anymore...

So Ill make it short now, thanks for the advice, hakim. Shame nobody could respond to the other questions though.

It's hard to say how long it takes to charge, because my device usually shuts itself off while charging. I guess the light on the power button stays on while charging, but it is faint and hard to notice when it goes off. I would say that it takes at least four hours, though, and probably longer than that.

In the User Guide, it states that the first full charging takes 8-12 hours. I thought it would be only the first one, but it still takes at least 8 hours and I find that dreadful. 3 days reading 2-3h/d and I can charge again, 8 hours... very uncomfortable...was very excited about it the first days but now am considering returning it and buying ipad mini instead, e-ink display is the only plus against the tablet (certainly not the battery life), and even that is not the contrast of e-ink carta in kindles

rkomar I see you have a lot of devices, can you compare at least in short PB 840 to other e-readers you have had in terms of battery life, battery charging time, e-ink contrast, ease of use?

I can't really do a comparison of battery life at this time. I'm doing a fair bit of development work for it, which means I have the WiFi on for periods of time. That really chews through the battery charge. I think the charging time is comparable for my 623.

In terms of contrast, it is worse than my 623 (Touch Lux), and even seems to be less sharp. However, I don't have any trouble reading on it, so I don't let that bother me. Currently, I think it's the only larger device with a light layer. It could be that the light and touch layers affect the contrast and sharpness more as the display gets bigger (the layers may have to be made thicker than for a smaller display). So, I think we have to wait for another 8" device with a front light and multi-touch support before we can make comparisons. I think Onyx is coming out with one, so we'll know then.

Since switching mine to v 4.4, I also decided to try using "bold" in order to increase the contrast. It definitely helps with both contrast and sharpness for ebook text.

john__doe, this doesn't seem right. I got mine last Friday, downgraded to version 4.4, fully charged it after seeing your first post and having played with it for a while. Since then, i 've been sideloading books, testing alternative reading applications, setting up the network and dropbox account, exploring the interface and reading pdf, yesterday alone i 've been reading for 3 hours, and the battery level is still at 84%.
Why don't you try version 4.4 too?

I 've noticed that while reading pdfs, after staying for about 5 minutes in the same page, the screen refreshes automatically and the font gets lighter untill i turn to the next page. The time indication of the bottom bar also disappears.

Is there a way to prevent this from happening? How do i turn on the bold setting?
