Battery goes flat quickly after using Calibre

jusmee · 04-23-2022, 09:29 PM

I have a Kobo Libre 2 and I use Calibre to add books to it.

The last few times I have added new books, my Libre 2 battery has gone flat within 24 hours of adding the new books. If I turn it off and on again (reboot it) it seems to return to it's normal state of good battery life.

I have updated Calibre and the Kobo firmware is on 4.31 from January (and it doesn't see any newer updates when I try). Also, in case it makes a difference I am running Linux Mint (latest) on my computer that is running Calbre.

A battery issue after adding books frequently means a problem with one of the books added. This can cause the import process to hang or leave something running that is using CPU and hence battery. Restarting the device will mean that process was killed or restarted. Finding the issue in the book an fixing it will solve the problem.

Though, with 4.31 there are other issues with connecting to a PC that might contribute to this. I don't remember if anyone reported this as a problem, but, the other issues might have hidden it. Updating to 4.32 is the best thing to do. From what I can see, this should be available as the update everywhere except maybe in Japan.

Thanks. Makes sense.

As for 4.32 I must report that I am definitely not getting that update here in Australia unfortunately.

I will look forward to it...

It should be available to you. From my checks, it is only the RakutenBooks affiliate that is not getting it. What affiliate does the device have? This is in the file "affiliate.conf" in the ".kobo" directory.

[General]
affiliate=RakutenBooks

What does this mean? This is a real device purchased from Kobo Australia.

I have read a little more. Maybe I should wait, or should I install the new firmware manually?

From my checking, the affiliate "RakutenBooks" is the only one not getting 4.32.19501. That isn't unusual, though I am a little surprised this time. It should be for Japanese users and there are font related changes that should help Japanese readers. As to why you have this affiliate, I don't know, unless your Kobo account was created with Kobo Japan.

As to updating, you can do it manually or change the affiliate to something else. Using "Kobo" should get the update.

Update to 4.32 and see how you get on.

I bought it from the Australian Kobo website. Oh well, I think I should change it to Kobo then to avoid future problems.

Update. Changed affiliate to Kobo, and the update duly installed itself.

Or just do what a lot of us do. Manually install the firmware when you want to.

Here is where you can get the link to the firmware.
