OP here - my UPower settings are the same as yours, and when I found time to risk my battery getting down to 2% (I only tried to 4% originally), it did indeed hibernate. Although it then immediately resumed :-(
Resumed meaning it really "woke up", without your intervention like pressing a key or so? If yes I'd check the journalctl logs, because that seems a little strange to me.
I had a similar situation a few days ago: I ran down battery until very low down. When the battery level was in what the system probably saw as critical (45%, something like that), it started sleep-hibernating (whatever the mix of these modes means), with journalctl writing (excerpt):
Starting Hybrid Suspend+Hibernate...
and seconds later: PM: Hibernation image created
and only woke up after I pressed the power button, IIRC.
So I guess I now have a different issue. BIOS maybe?
No idea: syslogs/journalctl might tell you what was going on:
The logs here are interesting anyways, and I'm still wondering where the system actually saved the image: in /tmp, or swap partition? ...
