Thanks for all replies. I will check the options for changing the cover image and the extended Kobo Calbre driver.
Regarding ghosting, I believe that a 1 Ghz processor should be able to figure out in sufficiently short time that a page has dark areas large enough to require a full page refresh. I am not sure whether any eReader or reader software can do this, but to me it just does not seem that difficult a computation. Setting refresh to every page works of course, but is annoying in its own right. (EDIT: So yeah, maybe this is more of a suggestino than a Bug) The PDF view-area settings freeze would have to be optional, but probably it would be unnecessary if the reader had auto-cropping. The reader should always zoom into the content at scale such that white areas on the borders are not displayed. Quote:
I know I could spend hours just perfecting the metadata of my collections, but that's a pointless activity given the millions of other readers with the same problem and the resources that vendors and publishers have. Quote:

EDIT: And another Suggestion: if an epub file has an embedded image, then zooming in that image should be much more convenient such as long tapping or double tapping the image and get it in full screen mode. In my case a book had a "hand-written" note in it, and using the zoom menu to make it readable did not go well with my reading-flow. Last edited by t.kruse; 05-30-2013 at 10:59 AM. |

Can anybody say how much energy their Aura loses overnight when powered off (or sleeping)?
It seems that my Aura loses about 5% when sitting unused (wether powered off or sleeping) overnight. At that rate, it would be empty in 20 days without being used. I can't imagine that this is normal... |

kobo aura hd first impression
i received my kobo aura hd a couple of days ago and here are my impressions:
1. the light is noticeably uneven at the bottom of the screen. i have it set at 50% and can see that the areas in between the 5 lights are darker. it only appears like this at the bottom, though. the rest of the screen is pretty much evenly lit. 2. very easy to add my own fonts. just created a folder named "fonts" and added whatever fonts i wanted. 3. there is a single pixel on the bottom right side of the screen that was leaking light when the light is on. not enough of a problem to return the device, however. 4. the very first night i got it, i left it charging overnight with a griffin powerblock dual universal charger. the next morning, i found that it was really warm. and it should have been at 100%, but showed only 96% charged. further more, it was unresponsive and the screen was displaying residual e-ink from a previous screen. i had to reset it by using the pin hole at the bottom of the device. after rebooting, residual e-ink was still showing. the longer i wait to change a page, the more the residual e-ink showed. only after the device has cooled down did the problem go away. i'll continue to use it for a while longer and see what happens. |

My device never gets warm when I am charging it. Does yours get warm when you charge it using either USB or another wall charger? People have said that you can't really overcharge a device or have too much juice come through a cable, but I think I would worry abit about the charger--or at least try a different one.

hi taming,

As for normal? When I got my first ereader, I already had about 150 ebooks that were either purchased or free downloads from various internet sites. By the time, I picked up my first Kobo, I was up to 1100. I've since added quite a few more. The first week I had the original Kobo, I added about 50 mostly downloaded from Baen catching up on some older titles. I average around 5 books per week. As for what does it matter? Kobo does respond to complaints about the books they sell. You might want to complain to the suppliers of your ebooks that have lousy metadata about their quality control. Quote:

Not necessarily, eInk is not great for that. Any zoom would do.
Currently, in the book this happens to me, ig goes something like this: "And then I read her note in handwriting: <picture of note>" If I long tap the note image, kobo opens the highlighting bar at bottom and shows a dialogue "No dictionary item found for ": ". Further allowing to look for translations of ": " and annotate this bit. Does anyone think this is more useful than a zoom as a reaction to long tapping an image? Oh, actually I see that there is no way to zoom within an epub at all, so that makes it even worse. I understand that in a text-only epub zooming has no point, but since epub allows embedding images, an ereader should support zooming in embedded images, regardless of via pinch, slider, or whatever else. I want to see those pictures in full, it is an expensive device, it can zoom in pictures, so why not let me do that in epubs? |

the one strange thing that happened was that when connected to the charger, the aura popped up a message thinking it's connected to a computer ("Computer detected" with the cancel/connect option buttons). i simply hit cancel and put it to sleep. |

The connected to computer popup is normal behaviour for a Kobo ereader, the software does not seem to do any checking when you plug in a USB cable as to whether a computer or a charger is at the far end. One cable I use which has only the V+ and V- lines connected triggers the connect to computer message. Regards, David |

Lithium-ion batteries are 3.7v, a value fixed by the basic chemistry of the cell, so any voltage exceeding that will do for charging. USB is defined to provide 5.0 volts (+/- a few %), more than enough. The more important question is how much charging current it can supply, which will govern how long the battery takes to recharge: current x time = total amount of charge delivered. A standard USB port is defined to supply up to 500ma, and USB devices are not supposed to draw more than that. USB chargers often supply more, up to 2 amps, and devices designed to use those chargers have various means of detecting when they are attached to their high-power charger instead of a computer USB port so they know they can draw more than 500ma.
However I believe that all the Kobo devices, including the Aura, are limited to 500ma max charging current. Since they do not come with their own USB charger, they are not designed to use a higher capacity, and they do not make any attempt to determine if the USB power source has a higher capacity. My Aura takes twice as long to charge as my Touch (2x bigger battery), and each takes the same amount of time to recharge from a computer USB port, or a 1 amp charger, or a 2 amp charger. I guess Kobo figures that it's not worth the trouble to do a fast charge since the devices need charging so seldom, although the nearly 4 hours required by the Aura with its larger battery is getting up there.

The Kobo chargers supply 1 Amp or 2 Amp http://www.kobo.com/accessories/kobo-charging-kit.html http://www.kobo.com/accessories/charger.html But neither of them say that they will work with the Aura although I think that they would. I prefer the wall chargers and they seem to work well with my mini and Aura, so hopefully they are not doing any harm. My understanding is that the device draws only the current it needs, please let me know if I am in error. Thanks Helen |
