he New York Times Easy Battery Saver+Task Killer (Free)

A common tip for first-time Android users is to download a tool to help manage your battery life and phone behavior. It deals with the phone’s network connectivity, screen time out and brightness. The sleep schedule alone may help save battery life by taking a break while you slumber through the night. There’s three modes this app operates in, with general, super and advanced settings. Super power saving mode, for instance, puts your phone on standby for as long as possible, while advanced customized mode lets you set the values for your phone’s energy-saving habits. There’s also an option to pause the service.
