Do battery saver apps really work that well? And if they do, are there any that you would really recommend? I have only tried one called Easy Battery Saver (link below), but it's hard to say if it really works, as some days the battery seems to last forever and other days it's only a matter of hours before it needs to be recharged, even without having used the phone very much. So do the battery saver apps really work or is it more of a placebo effect?
