Hi, rinigus.
Many thanks for this detailed explanation. I'll see and try.
This story with battery is by origin from N9. It's good application for N9(and symbian devices) EnergyProfiler. I know current in standbye mode(only 2G=on) for N9 is 7...9mA(2mA for N52) and for battery 1450 mAh -> 1450/9=161h=6.7days. Aqua Fish battery have 2500 mAh and for current 23 mA I have 108.7h=4.5days only. And it's close to my practice for this moment. It's bad.
I don't know why consumption is three times more but I would like to reduce consumption. I know the difference between N9 and Jolla_C, but... :-)
