Battery level drops suddently or fluctuates
- Battery level seems to be able to drop from 40% to 4% in a bliss (á la N9...)
- in most of these cases, phone will force itself to reboot after a while
- also spotted battery increase (in the order of 1-3%)

Are you okay with using the phone's developer mode?

might provide some useful information about what is happening. I've had similar symptoms after corrupting my contacts databse (which was my fault) and the contacts application getting caught in an endless loop because of that. It caused the CPU to be running on 100% constantly and the battery to drain in no time....Yes, I am confident. Problem is to be able to get into the journalctl on time when such a drop happens. For me this happens out of the blue, i.e. even with no specific usage of apps and just idling.
tortoisedoc ( 2014-02-26 22:34:26 +0200 )editCan't you just scroll through the messages afterwards, looking out for a section where an unusal amount of messages is logged in a short time period? You can also configure journalctl to persistent storage, allowing you to find out what has happened before a reboot.

chris.adams ( 2014-02-27 05:46:10 +0200 )editjournalctl -ba
to get the full log since the last boot. Note the settings in /etc/systemd/journald.conf to set persistence etc.I had a more or less similar case, that I reported in a comment over at "Jolla randomly shuts down" (see the second part of my second comment-to-question on 2014-01-17).
I haven't noticed it since then (even though I've had a rather large amount of the random shutdowns), so it may have occured again since ...
