Hi Olivier,

The same happens to me all the time since I purchased my phone BQ Aquaris
E5 HD one month ago. Basically everything works fine until I reach the
range of 50%-30% of battery. Then it goes crazily fast down to 0% with no
way to turn it on again unless I plugging it to the charger.

Note that this happens even with no applications opened (I activated
notifications only from the Telegram app), automatic brightness turned on,
WI-FI and GPS features turned off, but with the track location turned on.

I am glad to see that this may be a software issue and not an issue with
the battery. I will submit my /var/log/syslog as soon as I can.

Let see...
François
