Hi,
I'm using Snapdragon Profiler v2018.1.0.3302018 on a Sony Xperia XZ2 with firmware 51.1.A.4.173 Android 8.0 on Kernel 4.9.65.
Sadly none of the Power values work. Battery Current, Battery Level and Battery Power only show 0.

Is this an issue of my Platform?

Hi,
Power values get affected by the USB connection, can you please try ADB over wifi?
Oh, sorry i forgot to mention, i've mostly used ADB over WiFi. and it never showed up.
Just connected it via Cable now to check, and doesn't change.
What kind of Log could include helpfull information?
If you can share a logcat dump we may be able to determine more. You can use logcat's filtering functionality to capture only messages from SDP: adb logcat -s SDPCore.
Unfortunately we do not have access to a Xperia XZ2 device to attempt to reproduce your problem.

Connected via ADB over WiFi. Cleared Logcat, Started logging, connected Snapdragon Profiler, did a Realtime and selected all 3 Power Values, waited 10 seconds. Disconnected. Stopped logging.
Does that help or you need anything more?
Hi,
From what I see in your logcat it all looks OK to me as far as Snapdragon Profiler's operation. Snapdragon Profiler uses the underlying sysfs nodes located in /sys/class/power_supply/battery/ to get these metrics. Could you please try accessing them manually by using 'adb shell cat'. If they report 0 even from that location then the device itself may be obfuscating the values.

Seems like that might be the problem...
Can't access that without root it seems.
Edit:
Same Issues on the OP6.
But with root it works.

Hi Haldi,
Thank you for checking this. It seems that Snapdragon Profiler is incorrectly reporting that these metrics are available when it shouldn't since the nodes are not readable. I have filed a bug against it and we'll get to it asap. In the meantime as you pointed out, as long as the node is accessible (via root) you should get valid values through Snapdragon Profiler. I apologize for the inconvenience and thank you very much for helping us debug this further.
Cheers,
Carlos
