    what's going on guys, just recently, I have been interested in getting the 2015 rMBP. I was wondering if there was anyone that has gone from the 2013+ MBA to the 2015 rMBP, if so, is there a noticeable difference in terms of the battery life between the two? Or does it vary within what kind of stuff I'm going to be doing. The stuff I'd be doing on it is like web browsing, watch videos, listening to music on iTunes, coding (as I'm currently in school for computer science), possibly do some light video gaming. The macbook will be mainly used for school. Any feedback will be greatly appreciated, thanks.

    The rated battery life on a new 2015 13" rMBP is about 2 hours shorter than the 2013 13" MBA. On your two year old computer, you've probably lost a little capacity, so the difference should be less than that.

    yeah, I'm aware that there's a "2 hour difference" according to apple, but I was just wondering if that's really accurate. I see that you own a 13" 2015 rMBP, how's the battery life for you? do you find yourself having to charge the computer often?

    13-inch MacBook Pro with Retina display (early 2015, 2.7GHz Core i5, Intel Iris 6100) 11:23
    13-inch MacBook Pro with Retina display (late 2013, 2.4GHz Core i5, Intel Iris graphics) 11:18
    13-inch MacBook Air (mid 2013, 1.3GHz Core i5, Intel HD Graphics 5000) 12:51

    Those are the battery life results when running Engadget's standard battery run down test

    I have just bought rMBP 13 inch 2015 and also used MBA 13inch 2013. I use logbaterry to record the screen on, sleep or shutdown. Actually, ~2 hours difference is corect (8h and 10h, respectively) but I think it's ok with more advantage: high screen resolution (amazing), force touch trackpad, higher brightness.

    Apples battery life quotes are fairly accurate and most reviewers get more than advertised on their light use tests. Gaming will hammer the battery life on anything though and the rMBP's seem to be particularly poor if you use chrome and flash.

    oh that's actually not too bad..

    yeah it looks like people are getting roughly around 8~12.. depending on the usage of course. I don't know if I should just purchase the 13" rMBP now or buy it now and sell it when Skylake comes out or just wait for Skylake entirely

    If you need it now, buy it now, unless you plan on using 5K screens or have specific GPU needs the skylake 15-28W class processors look distinctly underwhelming...

    yeah..but since it looks like skylake might be coming soon, I'll just wait for that to be released. maybe there'll be a redesign for the new macbook pro, who knows. but nonetheless, thanks for all the inputs !
