I’m using the BQ aquaris E4.5, running rc-proposed (#159 as of yesterday).

This morning the alarm that normally wakes me up didn’t ring. When I
woke up by myself an hour and a half later, the phone had turned off.
I immediately thought "battery drain bug". When I plugged the phone to
a power source, the charging screen showed 48%, pretty much the level
it had before I went to sleep. So not a battery drain problem.

It took me a while to manage to get it to boot, after the initial "BQ,
powered by Ubuntu" screen the device would turn off again, or go to
the charging screen. I eventually managed to fully boot it after a
handful of retries, and there’s nothing suspicious in there. Battery
is indeed at 48%, the battery consumption graph shows a regular and
slight slope downwards, no peak or anything, and there are no new
crash files.

I’m also pretty sure I had closed all open apps before going to bed.

The only thing that I can think of is that the GPS was turned on,
whereas it’s usually turned off (I had turned it on for navigation
during the day, and had forgotten to turn it off again afterwards).

Has anyone experienced a similar problem? In such a case, what can I
do to help investigate the issue?

Cheers,

 Olivier (will set up a backup alarm clock just in case)
