Cool, thanks for the info! 
I quickly computed a median over my discharge rate using
My Jolla typically consumes 0.245 Watt being mainly connected to a WiFi and <10h a week via an UMTS data link and used quite a bit for reading news, emails, facebook... So the 7.98Wh battery (2100mAh * 3.8V) should typically last for 32.5h (1.4 days) which is a bit shorter than I observed (2.5 days).

PS: Computing the mean using the awk command below does bias short intervals with a high consumption too strongly (I get 0.448 Watt) and would suggest that my battery lasts for only 17.8h which is not the case.
PPS: If you look for the smallest discharge rate you see 0.011 Watt in the history which would result in 725h (30 days) .
I quickly computed a median over my discharge rate usingCode:
grep discharging /var/lib/upower/history-rate-7.dat | sort -k2 | awk '{ a[i++]=$2; } END { print a[int(i/2)]; }'

Code:
awk '{ if ($3 =="discharging") sum += $2 } END { if (NR > 0) print sum / NR }' < /var/lib/upower/history-rate-7.dat
Code:
grep discharging /var/lib/upower/history-rate-7.dat | sort -k2 | head

Hi,
you can check https://openrepos.net/content/radekp/battery-monitor for battery monitor application done by me.
It draws graph for charge_now values. Unfortunately the value refreshes quite seldom - so not very useful for short term measurements, but you will get pretty accurate graph e.g. if you manually refresh after a few hours.
Btw battery on my Jolla on 2G takes 7 days to discharge.

can you code a second screen based by 'history-charge-7.dat'?
i'm not a developer, so i can't support you...

It seems that with Sailfish 1.1.0.39 the files from /var/lib/upower are missing!

In version 1.1.0.39 we can use files from:
/var/run/state/providers/upower/
and
/sys/class/power_supply/battery
(apparently there are the same files)
/var/run/state/providers/upower/
and
/sys/class/power_supply/battery
(apparently there are the same files)
