Considering Battery Efficiency?

Trepn Profiler reports battery power. In order for the battery power to be the same as system power, the battery efficiency of the phone should be 100%. In practice, that number would be the less than 100. So does Trepn Profiler account for the battery efficiency while calculating power?

That's a good question Sugam. Trepn doesn't measure battery efficiency. Trepn measures system current at the power management IC (PMIC). That current ,along with battery voltage, is used to calculate the total power consumption of a mobile device.
