I'm trying to measure power consumption of an app, in order to optimize it.
Under settings, only Estimate Power Consumption is enabled for my device. And it's running Android 8.
The values it is showing seems to be valid. But I'm not sure.
When profiling the system, it shows an average value of about 400mW.
How accurate is the value?
I don't care about the values to be precise, but I expect to get a correct delta value of power usage after implementing the proposed fixes for the app.
Can I depend on Trepn for this use case on my device? If implementing a fix shows a 20% less power usage on Trepn, or if it shows no change, will that be dependable?
