      Description

      Some MacBook Pro computers can automatically switch between an integrated Intel graphics card and a discrete NVIDIA card based on needs.

      Qt Creator 3.0 causes these computers to switch to the NVIDIA card, which will significantly reduce the battery life (< 5 h vs > 7 h). Qt Creator doesn't really require high performance graphics so this should not happen.

      To test this, you can easily keep track of which GPU is in use with this utility: http://gfx.io/
