    Hi, I have a late 2013 rMBP and used to have around 10-11h of web browsing ability in the past.. Right now, I have 1h of Safari web browsing and battery went from 100 to 61% (mostly browsing macrmours forums, so I didn't watch any movies or any heaving processing.

    Am i alone?

    thanks!

    Have you tried resetting PRAM? I had an issue with a 2012 model where it displayed over 30% battery life while in reality it was under 5%. Couldn't figure out why it kept shutting down on its own until I reset PRAM, and it showed the correct values.

    Look in Activity Monitor, Energy Usage tab, better than guessing...

    I looked but safari is there, but I used to get 10-11 hours not so long ago.. so it's really weird to see bad battery performance all of a sudden. When I look at the safari tabs, they all show that High performance GPU with a NO. I have no major applications running besides :
    - shuttle (0.01%)
    - 1password (0.07%)
    - little snitch (0.22% energy)

    If nothing is there now then it may have been indexing Spotlight or similar.
