    If you use Chrome, expect battery life to be halved.

    Apple claims "up to 10 hours". That doesn't mean you'll get 10 hours. It depends on your settings and workload, which varies widely. Also, the "Time Remaining" is an ever-changing estimate, based on the minute-to-minute power demands of your computer. It is not an accurate indicator.

    There are many factors that impact your battery life. See the BATTERY LIFE FROM A CHARGE section of the following link for details, including tips on how to maximize your battery life.
    The link below should answer most, if not all, of your battery/charging questions. If you haven't already done so, I highly recommend you take the time to read it.

    10 hours is about right with the brightness at 75% like they say and not gaming heavy.

    Yes. I got 2 hours of Civ 5 gaming at 2560x1600 hidpi. It's a little less than I got with my MBA, but the game does run smoother.

    Mine was delivered on Thursday. Updated my Signature with the stats. I charged it to 100% immediately. Have not charged it since. Wanting to see how long it takes to get it down to 1%. Currently sitting at 16% as I type this reply.

    I would guess that I have easily used it 10 hours since then. That includes multiple power on and off. Downloading and installing software. Installing all of the OS and Default App Updates. Watching some YouTube videos. Today I have not powered it off at all, just close the lid to put it to sleep.

    Would never come anywhere near this kind of life on my 11" MBA. I am extremely happy with the battery life of this new model MacBook.

    I know it says "up to" however i've had a string of issues with this rMBP, choppy UI, fans randomly going mental even just after booting.

    The above screenshot was taken with with nothing running and only just booting the laptop up, well after letting it calculate the time. Its just really random, i was on the phone with apple care yesterday and i lost 2 hours in 10 mins on the phone which is just weird, that was just browsing using safari and my activity monitor had no unusual CPU or battery usage. Im not asking for a perfect 10 hours but i would like to be able to have an idea of how long i have and even at idle i would like near the 10 and 100%. FYI i also have my screen brightness under 75%

    i have an appointment with a genius person wednesday and if they give me the whole spill off "so many variables" etc i will just return it. I've lost a lot of confidence in this laptop and really i just want this one exchanged now.

    Mine says that too if I have Chrome open or watching a youtube video or something, but it usually lasts way longer then what the indicator says.

    There is never "nothing running" if your Mac is turned on and OS X is up. Check Activity Monitor for a list of the currently running processes on your Mac, even if you haven't launched any apps.
    Stop reading the time remaining indicator. As already stated, it updates constantly and goes up and down, based on the minute-to-minute workload of your Mac. The only reliable time indicator is to see how long your Mac runs on battery until it shuts down. Even that will vary every time, as your workload and power demands will change. Stop obsessing about the time remaining indicator (that's why Apple removed it from the Menu bar) and enjoy your Mac.
    If that's the case, you should return it and not buy another Mac notebook, because you'll face the same issue with every Mac notebook that Apple sells. It does depend on a variety of variables. There is no such thing as a "standard" amount of time that any Mac will run on battery power, because it depends entirely on each user's settings and workload.

    Chrome is terrible for battery life, which is too bad. I can't figure if Apple or Google is to blame for the Chrome experience.

    Is it because flash is built in? or that aside, battery life issues with Chrome?

    Now is this just forum hear-say? Or did someone actually measure the differences between using it and not?

    There have been numerous reports of significant performance problems with Chrome, enough that it's very likely that there's merit to such claims. A quick search of the forum will reveal this:

    Yes, but this is still forum hearsay.

    The only reason I have been able to find why Chrome is supposedly a battery hog is its use of the dGPU on MacBooks that have it. This would obviously not apply to the rMPB 13" or MBA.

    Chrome for Mac is 64bit. These "cut battery by half" seem to be exaggerations. I have not observed this, but if some have, I would venture to say there may be other things causing these issues. Chrome is a superior browser than Safari, especially for those of us who use Windows and want to keep things synced. If there is something worse than Safari for Mac, it is Safari for Windows.

    Actually, it's not hearsay, as the posts are made by users with first-hand experience with Chrome, as opposed to just repeating what they heard someone else say. Now, how scientific their analysis and findings are is up for debate, but it's not hearsay.

    It's an ongoing issue. In November, Chrome got a pretty significant upgrade to 64 bit, but I'm still not surprised people are seeing issues.

    It used to be really bad. The first Sandy Bridge Macbook Pros would see crazy performance hits on Chrome. My Mac now does not seem to have much of an issue anymore.

    Perhaps make a new user and don't install any of the third party stuff, reboot and login as the new user,see how that user goes, I've had Dropbox go bad and batter a battery before.

    I ran it on my 13" rMBP and it just hogged up my battery. It's the way it was badly coded.

    Having Flash built in doesn't help either. Chrome Canary seems to improve battery life somewhat, but nowhere close to that of Safari.

    Did you do a Time Machine Restore? Could it be that you brought over some buggy apps from an older Mac?

    Perhaps a clean install and test it out with just the original apps for a day to see if battery life changes?

    got a 2015 13' rMBP...been a chrome user for a good 6 years...but it kills the battery life on this thing. With safari I'm getting 9-12 hours on a full charge

    Smoother on the Air or the MBP?

    I'm considering replacing my 2013 15" for a 13" rMBP, but I don't want a noticeable drop in performance in LR or when I infrequently run a VM.
