My game is about done, and I'm noticing that it tends to chew through battery pretty well. I think this has gotten worse since I added sounds and music. There may not be a lot I can do about it at this point, since the whole game is a house of cards assembled over two years of learning, but who knows? Sometimes there are small tricks that can make a big difference (e.g., disabling the application surface to improve mobile FPS, unless they fixed that now). Does anyone have ideas about minimizing battery usage?
