Here we present the results for voice call services.
Power consumption when making and receiving a voice call.
Number of tests:
During the measurements the other air interfaces (BT and WLAN) are switched off.
The power values for the calls have been obtained by making a phone call of five minutes duration between two phones for each test. Then the average of the power consumption of the two phones for all the tests has been calculated. The power consumption during the idle time has been calculating averaging the power levels over eight hours of idle mode.
All the tests have been performed using a SIM card from Sonofon in Aalborg, Denmark.
Results show that making a call using GSM costs 46% less energy and receiving a call costs 50% less energy than using UMTS. Being idle while connected to a GSM network costs 41% less than UMTS.
