Maybe if you update firmware to latest version, disable auto update, things that use WiFi. But no, it shouldn't drain battery that fast, even if you're reading, you wouldn't use battery that fast. It looks like it tries to do something and uses all resources (processor, WiFi) to the max.

I did all of this. Kobo figured it was a faulty device. Got a new one. Same thing now. Within 24h : no battery left. I think the problem might be coming from the ePub file I'm currently reading? I see no other option.

It would be interesting to see if anyone else gets the same battery drain so if the epub you are currently reading is public domain/not copyrighted, you could post a copy here. Otherwise, checkout the ScrambleEbook plugin for calibre, scramble the book and then post the scrambled book here.

Which is that? You can view version number from Menu -> Settings -> Device Information

Hey everyone. My ereader drains battery very quickly on sleeping mode. It went from 82 to 58 in less than 4 hours for no reason. Is it normal for this ereader or is something wrong with it?
That is definitely not normal. Sleep should hardly use up any battery, especially not in only 4 hours.

I recall a few years ago there was a bug that drained the battery down in sleep mode when something was touching the (IR) screen at the time the device went to sleep (on the Glo at least). But I can't remember what firmware version it was or whether the bug was present on other devices.

It might of course be something completely different... faulty book could also be true, as I think you suggested in a different thread.

Edit: Oh, I see I wasn't at the last page of the thread and replied to an older message... oh well

Firmware is 4.9.11311

I did remove all the books that I thought could cause the problem and still woke up to the same problem today. I'm getting very tired of this

The most curios thing is, this is your second device (you wrote that Kobo replaced first one, right?).

It is possible that there something wrong with battery, but that same thing is wrong on two devices with same owner? I guess it is much more probable there's something with your setting (like something with WiFi, or similar) that affects your device(s).

Not sure what, but I'd check settings, including completely disabling WiFi (i.e. not even logging to router after factory reset).
