    I've read the battery on your Macbook 2015 runs down faster after installation of the GM. I am often away from a charger and need max battery life. Is this true?

    Any other issues?

    My late 2013 MBP gets horrible battery life since going to El Cap. I figured it was just the fact that it was beta software and to be expected. Now that it's on the GM, it's no better. I get 2-2.5 hours or so. Used to be able to get through the good part of a day without a cord; now I need to connect for a single meeting.

    I got about 2 hours of use processing some photos and surfing the web on a Macbook 12. I would say I am normally at 60 percent after an hour or two of use. I was down to 16%. I have never run down this much during the day. I am surprised. Hope it's my imagination but two hours is not good. I processed about 40 raw images.

    Huge battery drain with the GM Candidate. MBPr Mid 2014, fully charged, it indicates 4.5 hours with just Safari opened, and I cannot stay for more than 4 hours away from the power, 2 hours if I just open Parallels. It was from 6 to 10 hours in these condition with Yosemite.
    Restarting the Mac does not solve the problem.

    Similar situation here. Used to get a solid 9-10 hours with light use, and about 6-7 hours with heavy use on my MBP 13 (late 2013) on Yosemite, then stats dropped to like 4-5 hours on the El Cap betas. With GM, there seems to an improvement, but its erratic. E.g. Yesterday, at around 50% battery, it said 2:20 remaining. Today, after recharging, at 50% it says 6:25 remaining (both similar days usage was similar - mainly reading documents, and some web browsing).

    Just installed 10.11.1 Βeta and the situation seems to be even worse!

    Did you check in Activity Monitor what was going on?

    CPU Idle for the 90 to 97%. The rest was used by some services ad Box Sync, Dropbox, Safari, Excel...

    I did reset the SMC today but nothing happened. Still a ridiculous battery life (less than 4 hours) compared to Yosemite, without any noticeable improvement in speed! Time to downgrade this weekend then. After 15 years of Mac, this is the first release I got massive troubles with... :-|

    Weird. I'm getting a solid 7 on my 2011 13" with over 400 cycles on the battery.

    Let's face it.... The GM is no better than the betas. It's gonna be 10.11.5 till we get back to a reliability and performance level on par with the first release of Yosemite.

    Battery estimation is just an estimation. Yeah, it was showing 5 hours here at 100%. Two and half hours later I am at 70% and it shows 7 hours left. Most likely your battery statistics was reset and the system needs some time to learn from the data again.

    I do not think so. I cannot arrive from 9:00 to 14:00 with a light usage. :-|
