MacBook owners have long cursed Chrome for its tendency to drain battery life at a rapid pace, and some have used it as an argument for why you should switch to Safari or Firefox. Fortunately, there's a way to track down problem tabs and increase battery life by substantial amounts, thanks to one of Chrome's built-in utilities.
Chrome's Task Manager is similar to OS X's app-monitoring Activity Monitor, as it provides a real-time report of how the browser's tabs, extensions and processes are impacting your system performance. Web developer Primo Cigler claimed that terminating the tab that was hogging the most of his Mac's resources doubled his MacBook's battery life, so this may be prove a valuable technique to save your computer's juice.
