Juice Defender is one the ugliest battery saving application. Still, for years it has remained one of the most trusted and highly ranked among users. If you pay for the Ultimate version you will not believe number of options available, but even with the free version is remarkably effective. Just activate Juice Defender and decide on a profile - balanced, aggressive or extreme - though the latter can only be customized in the paid version.
