Today it's using 1% per minute, it is too much. I'm connected through mobile data network. I'm playing Sudoku, it uses 20% CPU, 13% is pulseaudio process.

Last day, when it only was using 1% every 5 minutes, I was connected through Wifi, but later I connected to 3G ant it was using same battery. Perhaps I must connect to wifi and then switch to 3G. It seems a bug.

I will try to find out when phone saves battery and when it's draining.

I'm testing now. It uses 1% battery every 5 minutes when screen is on, it's acceptable. In my workplace there are a lot of battery draining, perhaps battery draining occurs when there are bad mobile coverage.

I confirm battery draining in BQ 4.5 since OTA 3. I have my BQ since October 2015. In December 2017 there was fewer battery loss, so I discard battery malfunction.

There are no battery draining when phone is in sleep mode(screen off). It can stay 2 hours and only uses 1% battery (sometimes 0%). But there is a lot battery draining when screen is on (2% per minute). I have screen brightness at 25%, as I have before and there was fewer battery loss.

I've executed 'top' in Terminal and there aren't processes using 100% CPU, they only use about 5%

In another thread someone says to disable auto-rotation, I will try this
