-Test Duration : Battery tests for mobile devices need to be run for 24 hours to get an accurate understanding of avg. battery consumption by the app. This allows the readings to correctly take into account a typical usage of the device by a user.
- On Android Devices : When zIPS is started for the first time it runs a comprehensive check to ensure the device is safe. So within the first hour the battery statistics will give the perception that battery usage is high. But accurate readings can only be captured after the app has been running for atleast 24 hours on the device.
Consider the case on the following screenshot attachment :
First, some definitions :
- Usage : Time that the phone was used (i.e. not asleep)
- Standby : Total time the phone was without charge, including time on deep sleep (i.e. when the screen is off).
- zIPS Percentage : Is the percentage of the total battery that was used by zIPS.
Using the data from the above screenshot as an example, here is how the battery consumption for zIPS can be calculated :
Device Battery Usage = 100-53=47%
zIPS Battery Usage = 0.21 x 47% = 9.87%
Battery Usage by zIPS per hour = 9.87 % / 16.25 hrs = 0.60% per hour
