    So I've had the Retina Macbook since launch and continuously achieved near 10 hours on a full charge. Now I'm getting 3.5-4 hours. I've applied every update and I'm running the latest public build of El Capitan. I've attached screenshots from my activity monitor. The battery indicator blames Safari. I have one window open with 5 tabs and Safari isn't a problem according to Activity Monitor. I've had 5 windows with 40 tabs open before and still got great battery life.

    What should I do?

    Did you check your battery health stats using system report in about this mac? If your full charge capacity has taken a dive then maybe you've got a dodgy battery in which case, warranty repair time.

    I'd call Apple, of all the Apple laptops (MB, MBA, MBP) I've had, they have been very consistent in the way the battery performs. I think it's one area that Apple understands well and has properly engineered.
