He, darn, I did not look at the exact level...
I had a battery monitor with four bars running and one bar was missing.
This mean that we lost something up to 25%.
I will try to make this more exact, promised ;)

Just for now the only way for me to query that more exctly is to issue a
command on the console which I only have with USB - and with USB
connected I do not get level readings ;)

Sure, will try that ASAP!
Makes sense, if it is not yet configured anywhere else, cool stuff!

Should it be that easy?
