Battery life is one of the most important elements of a modern mobile device. That's why iMore's battery life tips are some of our most popular articles, and why our comments, social feeds, and forums are filled with battery life questions, boasts, and complaints. Apple prioritizes battery life above almost everything else, even making the iPad 3 and Retina iPad mini ever-so-slightly thicker and heavier just to maintain 10 hours of battery life. Yet some apps, especially those that use VoIP like Skype, that use GPS like Google Maps, or those that have rogue processes or other glitches can still chew through power at an alarming rate. That's where battery shaming comes in. Battery shaming was introduced on the Mac with OS X Mavericks and I'd love to see something like it on the iPhone and iPad in iOS 8.
