Fenix 5x HRM-TRI is it possible to disable Running Dynamics?

Hi to all! 

I recognized, when using the HRM-TRI for running, i need much more Batterie on the 5x. (10% an Hour)

which i don‘t think it is a bug, it just have more Data to calc and Store. 

is it possible to disable running Dynamics? So it would use same less energy then the HRM Premium I had before? (5-6%) 

Thanks for your info!
