Yes, I'm 100% sure that overnight automatic sync occasionally gets stuck and drains the battery. I try to remember to always turn off wifi and only manually sync, and abort the sync and restart it if it takes too long, and give up (and try later) if that doesn't fix it.

But occasionally, the wifi gets left on and sometimes I find the battery drained the next morning, sometimes with sync still running. And sometimes I turn off the wifi and sync keeps running for another 5 minutes or more until I just reboot.

Good suggestions. I haven’t shut off auto wake and sleep, but I did turn off auto Natural light. However, I’ve been sick in bed and reading a lot—much more than usual. This could account for the battery “drain”, but it’s not as if I’ve never binged read before with this KLC.

However, I did some experiments and discovered that the light stays on when the sleep cover is closed. This puzzled me because it’s new behavior. If my sleep cover was at fault, wouldn’t I have run into these problems before this firmware?

I thought back to what settings I had changed since this latest firmware, and I had enabled screenshots to the power button permanently because the page turn buttons can now wake the Kobo up from sleep. So I have now disabled screenshots and will monitor its behavior. So far, so good.

As for the pages changing while the sleep cover is closed, it could be related. If the sleep cover isn’t turning off the Kobo, then it’s possible that while I’m holding the Kobo, the page turning buttons are being triggered.

Firmware 4.41.23145

I can verify that the problem happens on both sideloaded and purchased epubs, but mostly with sideloaded books. I just opened a sideloaded book and discovered it was over 30% through the book. My last bookmarked page was at 6%. The light is no longer staying on when I close the Kobo cover, and battery life seems to have normalized, so my changes above helped, but I’m still having a problem with wandering last page read when opening a book.

My next step is to monitor the percentage of completions. Is the reading location wandering when I close the book, while I’m not reading the book, or when opening the book? Maybe it only happens when I use the bookmark feature. I just opened another book, this one purchased, and it was on my last read page. No bookmark. This seems mysterious and baffling atm, especially since nobody else seems to be running into it.

I did not have these issues until I upgraded to this firmware. Any suggestions?

Sorry but it does seem as if you are having a one off issue.

I open the cover and books are on the page they were on when I closed the sleep cover. Auto sync is off if that helps.

I'm assuming that your sleep cover is from Kobo? I have seen complaints from one person who had a third party cover where the magnets were either not strong enough or were not positioned properly so their KLC keep waking and going to sleep when the cover was closed. To add to their issues, the dimples over the page turn buttons were slightly mislocated. They returned the cover and the replacement cover hasn't caused any issues.

Well, something’s going on, and although others may not be having this issue, I didn’t have it either until the most recent firmware. After I posted above, I put my Kobo in my carry bag, but didn’t touch it. Ten hours later, the most recently opened book went from 1% to “Finished”.

I’ll remove the Kobo sleep cover (official one purchased from them) and see what happens.

I wonder what the warranty is on the sleep covers. We’re over six months since I purchased it, but if the problem goes away without the cover, I may reach out to Kobo. Odd that this didn’t start happening until after I upgraded, though.

Are there any other magnets close to the reader? Does the carry bag have magnetic closures, for example?

I once had a very nice after-market cover for a Kobo that I couldn't use. There was a magnet that held the kickstand on the back of the cover closed, and it played havoc with the sleep-wake function.

[/QUOTE[

I've also noticed wandering last read page, but usually for me it goes backwards and not more than a page. Or I bumped something before closing the cover, idunno. Will have to watch more closely.

But note that there are a number of things that could cause phantom page turns.

For instance, if your sleep cover isn't working well and the kobo wakes up because something shifted, and something managed to register as a touch/hold on the corner of the screen, the kobo could go into quick page turn mode until it hits the end of the book...

I thought quick page turn could be disabled, but I can't find the option if there is one.

You could try disabling the sleep cover in the energy options and see if the problem goes away.

Remember. I only started experiencing these problems after upgrading. My Kobo LC wasn’t anywhere near the magnetic clasp of the bag, and I’ve been carrying around the two of them together since I got the LC last Spring. Nothing has been different in my setup than what I’ve described, and, as I already mentioned, I have an official Kobo sleep cover. Is this behavior a coincidence? Perhaps, but it’s suspicious.
¯\(º_O)/¯

I appreciate all the good suggestions, though. That’s what’s great about this community.

Instead of doing that, I removed the sleep cover entirely. I can report that after a day there have been no aberrant last page read moments. But I also haven’t been carrying my Kobo LC around with me.

I don’t like having no protection for my reader, so I’ll be disabling automatic sleep so that I can still use the cover. I’ll give it another day of typical use with the disabled cover and see if there are any more incidents.

I appreciate knowing that I’m not the only one who has encountered this issue. Just to verify, these issues began for you with this firmware update?

I've only noticed since the last firmware update, not to say it didn't happen before and I forgot.

I've only seen my last read page unexpectedly change a few times, and it's not enough to be sure I didn't fat finger it before closing the cover.

And messing with it, I can't get it to repeat.

Like I said, I'll pay more attention now.

Hello, everyone. Yesterday I bought Kobo Aura HD. From the first touch it performed overpoorly. It is fantastically slow. I thought that maybe it was due to the latest update (now it is 4.35). How can I downgrade the firmware in order to make it work more or less normally.

PS. Nokia 3310 compared to my e-reader is a starship!

I haven't had the problem in the last few days, but I had a problem where I would open a book I was like 30% through, and it would be all the way back to the first page. It seems to have subsided, but it was annoying.

For those of you who are experiencing the wandering last page read bug with this firmware, what kind of sleep cover do you have? Mine is the official KLC cover. Even with auto sleep turned off, I am still experiencing this bug. The current read will open up somewhere before or after my bookmark, sometimes a few pages, and sometimes a massive amount of pages, even if my KLC is left alone to itself on my table. It’s quite mysterious.

The only thing a problematic cover should cause is battery drain or not going to sleep when you close the cover. I cannot see how a funky cover would cause the page number to be forgotten or changed.

If the device is waking up while in a bag, you could also be getting phantom screen taps or button pushes.

Note: I haven't seen any page wandering in the last 3 days. I think it's just as likely I forgot what page I was on and only thought it had changed.

I have the official Kobo sleep cover with the pen slot, for what it's worth.
