Can anyone comment if the GM fixes the battery problems Beta 1 had? I was on the first beta awhile back, and my 2012 rMBP got about an hour battery life (I usually get closer to ~3-4) and was always hot to the touch.

The same thing happened to me with Mavericks, so I chalked it up to Apple not optimizing the early betas for battery life.

I'm on DP 8 on a 2015 rMP, Sitting reading documents and playing music in iTunes without doing too much I get around 11 hours battery life, with moderate use of git, sublime text 3 and some Firefox (Nightly) I get between 5-7 hours depending on how much I use Firefox which is the main battery killer.

Excellent! I guess now is the time for me to finally make the move over to El Capitan, since your usage seems pretty similar to mine. Thanks!

Those are usually no battery or power management related problems, but "rogue program eating too much CPU" problems.

Usually it's Spotlight, but a look in Activity Monitor would have shown the culprit.

There are lots of diagnostic reports that are run in beta versions.

On the latest beta of 10.11, I easily get 8-9 hours battery life with brightness set to the middle with Safari, iTerm, Mail and iTunes running.

Are you using Chrome/flash at all?

I'm on beta 5, on a 2009 macbook 15 in, I'm getting great battery life, but i feel like my lap is on fire.

ya ya ya i know its not good for the boys down here but i had no choice!
