Is there a way to know if the tablet is connected to the power supply or not

Question

Is there a way to know if the tablet is connected to the power supply or not because our game runs slower when it doesn't.

If there is an event or method to get that information it would be helpful

Thanks!

Answer 1

Generally speaking, Metro style apps cannot get hardware details or power management state information.

See http://msdn.microsoft.com/en-us/library/windows/apps/hh464945.aspx

You can use your own dynamic frame-rate computations to determine if the game is running 'too slow' and scale back or have user-configurable settings that let's them adjust it directly. You don't really have a way to infer 'why' and it really doesn't matter. Users of tablets are going to want to run on battery most of time time anyhow.
