I generally use "Battery doctor" from play store, to kill all unneccesary progs in background. Together with flymodus and activated bluetooth and an extern BT-gps-mouse, I have no problem to use Locus for more than 10 hours with my S4.
Last track yesterdy was 15 km 5 hours and still 80 % battery left.
