@jpel try

Code:

qdbus --system org.freedesktop.Hal /org/freedesktop/Hal/devices/bme  org.freedesktop.Hal.Device.GetAllProperties

There is also RemainingActiveTime.

And RemainingChargingTime:

Code:

#!/usr/bin/python

import QmSystem

batt = QmSystem.QmBattery()
time = batt.getRemainingChargingTime()
hours,mod = divmod(time,3600)
mins,secs = divmod(mod,60)
result = ''
if hours>0:
        result+=str(hours)+'h '
if mins>0:
        result+=str(mins)+'min'
if batt.getChargingState()==1:
    print result
else:
    print ""

But there is one problem: when not connected to a charger, it show all the time 59min.
Can someone fix that, because I do not know how to do it. Or is it even possible to get this to work correctly?

E: corrected and put in for testing.

Code:

if batt.getChargingState()==1:
    print "charging"
else:
    print "not charging"

Actually i already tried by modifying your earlier python script for determining remaining active time to following:

Code:

#!/usr/bin/python
import QmSystem
batt = QmSystem.QmBattery()
idle = batt.getAverageIdleCurrent(QmSystem.QmBattery.NormalMode)
active = batt.getAverageActiveCurrent(QmSystem.QmBattery.NormalMode)
print "Active:",active,"mA","  ","Idle:",idle,"mA"

But the problem seems to be that there is no battery usage data collected by the system default as the script returns every single time it is been run the same output: Active: 203 mA Idle: 23 mA

I guess that in order to this work and give reliable results you would have to use:

Code:

startCurrentMeasurement (Period rate)

wait some desired time to gather data and then stop measurement with

Code:

stopCurrentMeasurement ()

before requesting and displaying the desired batteryinformation.

I was thinking if there was an easy way of getting all this information from battery usage app that has already all needed data gathered since the last recharge.

Nice module, this QmSystem...

Power saving mode state:

Code:

#!/usr/bin/python

import QmSystem

psm = QmSystem.QmDeviceMode()
psmstate = psm.getPSMState()

if psmstate == psm.PSMStateOff:
        print 'PSM off'
if psmstate == psm.PSMStateOn:
        print 'PSM on'

@Soltee:

Install the QmSystem module (apt-get install python-qmsystem as root) and it should work.

Edit:

Now I read your post properly. I left the link to gitorious...

There is a python example for battery related stuff here.

small variation.
shows remaining charging time if charger connected
shows average remaining usage time ( (idle+talk) / 2) if charger disconnected
using current psm mode to detect remaining time (powersave or not)

Code:

#!/usr/bin/python

import QmSystem

batt = QmSystem.QmBattery()

if batt.getChargingState()==1:
        time = batt.getRemainingChargingTime()
else:
        mode = QmSystem.QmBattery.NormalMode if QmSystem.QmDeviceMode().getPSMState() == 0 else QmSystem.QmBattery.PowersaveMode
        time = batt.getRemainingIdleTime(mode)
        time += batt.getRemainingTalkTime(mode)
        time = time/2
hours,mod = divmod(time,3600)
mins,secs = divmod(mod,60)

result = []
if hours == 1:
    result.append('%d hour' % hours)
elif hours > 0:
    result.append('%d hours' % hours)
if mins == 1:
    result.append('%d minute' % mins)
elif mins > 0 or not result:
    result.append('%d minutes' % mins)
print ' '.join(result)
