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...
