I think that there is no power saving mode in this device (at least, I have not found it).

Everything is frozen via the snowflake icon.

Also, Settings/Power/Battery Status does not show me any detail on the consumption by app. I tried clearing cache, but still does not show relevant info (I get the message "Battery usage data isn't available)" (shown in attached images).

Check your books - at least one of them prevents the NeoReader from going to sleep and if it works, it needs power.
Due to Settings/Power/Battery Status not showing any details on the consumption by app, I need to rely on 3rd party apps. Would you be so kind to recommend a better option?

My device has a power loss (on sleep mode, doing nothing) of 1% each 38mins, approximately 2% each hour, but without USB cable connected (which is similar to what you report with a connected cable, in your thread). Have you found some other clues on this behavior, so far?

My device is old but has very recent FW upgrade. I would be surprised if onyx has removed the feature. Perhaps someone with a newer version could confirm. I access it by tapping the top bar in the home screen. It appears as a battery icon. I would also freeze all apps. Have you installed any apps that might cause this? It is also possible that a bad book can cause battery drain. Reboot the device and if all else fails to a software reset.

Everything that monitors needs power.
Question: If the Neo Reader is not used, why does it appear first?
Answer: because it is busy with a book!

My suggestion: reset the device and then check the consumption - with no book and nothing installed.
