Then I recommend that you test it for yourself to verify the account team's result.  If you can reproduce the results then an SPR can be opened. You can also go to Microsoft's web site and look at the definition of this API to see if it is supported in this version of the OS.

The GetSystemPowerStatusEx2 function is a microsoft function and so, is supported.  However the BatteryCurrent field in the returned structure is 0.  I have seen this in many of our devices.  There is an SPR open on this issue.  Is there some reason the customer need instantaneous current (this value can vary widely and changes many times per second if there is a radio,and really has no reasonable meaning).  There is an AverageCurrent field which might be more useful.  This field is filled in in the devices I've checked.

Have you tested and are asking because it's not working correctly?

I have not tested it myself, but a TA says he tried it and the batterycurrent value always comes back as 0. thanks.
