Battery hog

Simple app that works like its supposed to, EXCEPT that its an enormous drain on the battery. All it needs to do is click regularly, but after I practice with this thing on for just one hour, my otherwise good battery is down 30% (the only other apps that come close to that stream video). Okay when he phone is connected to the charger (but it still gets really hot then while running this app), but terrible otherwise.
