Google Chrome 57 Will Throttle Background Tabs To Save Battery

Google is continuously improving its Chrome web browser by making sure that it doesn’t eat up laptop battery life. For Chrome 57, Google has added a stronger feature by throttling open tabs that are not in use.
“To prolong battery life, Chrome should minimize power impact from things users can’t see. This includes background tabs, which consume a third of Chrome's power usage on desktop,” Google Chrome software engineer Alexander Timin said in a blog post.
