    I was checking out the 2016 15" rMBP at one of the Apple Reseller stores and it was whopping 96% yet it just said 3:44 hours of battery time available. Does anybody get a complete 9 hours of battery on the new 2016 15" rMBP ? I am planning to buy it but am shocked with the battery back up ! That's horrendous !! Any thoughts ??

    Depends on what background processes were running on that machine. At the beginning a MBP will not dleiver 10 hours as processes like spotlight indexing the computer, eat a lot of resources.

    But there definitely are people who reach the 10 hours as advertised, else Apple will face a class action lawsuit very quickly.

    Try not to get pulled in to thinking that the "remaining time" is an accurate indicator that tells you everything that you need to know about battery life in general.
    Keep in mind that the in-store example won't be running on battery for any significant amount of time. It would likely be plugged in. So, that usage won't give you any true indication of real battery life.
    (hint: unplug that MBPro, then come back in 3 hours 44 minutes. It likely runs a demo when left to itself, which could also be a power-sucker. I will bet that battery lasts longer than 3:44 - probably double that time.

    Apple, not surprisingly, does have something to say about battery life, and general tips for getting more life out of your battery

    But you are basing your point on assumption.

    well, yes, I suppose you are correct. I am assuming that a one-time examination of a known-to-be inaccurate indicator, may not be enough information for you to state conclusively that the value represented to you on that indicator is accurate.
    So, I can state that you are also assuming from your one-look examination that indicator is always accurate. It may be - depending on your particular usage. You can make no such assumption on a system where you don't have knowledge about how that system is set up. Yet, you appear to be willing to assign battery life issues with every new MBpro, just on the "evidence" from one display model.456
    How do you get around that little difficulty? Run a battery life test...

    Factors such as background processes, display brightness, key brightness and general power saving settings will all play a big part. On around 50% brightness with minimal keyboard brightness and average use (browsing, music, movie and word processing) I am easily hitting 10 hours. If I notch up the screen brightness to around 70%, I get around 7-8 hours of battery life.

    I use alfred a lot and type q > enter that seems to close all open apps.
    I have not explored alfred as much as I should, yet I use it for this one task a lot.

    Apple clearly describes on the product page under which circumstances the 10h are reached in their tests. It is obvious that it doesn't reach 10 hours when you do heavy tasks like rendering an animation or playing games.

    If you do the tasks they mentioned on their product page and you do reach like 5 hours only, then you are entitled to a refund/repair depending on the country you are living in.

    This is a funny topic. Apple makes sure that the screen is brighter than any other laptop screen, which is a great feature! But then people turn up the brightness and complain that their battery time is not 10 hours.

    That proves that there are people who will never be happy with what Apple is doing. They will always turn things around so they can complain. It's either the battery time or the power. And in any case they will say "of course the one I am currently complaining about, is the more important part".

    augustya, would recommend you to read up a bit in this thread, you'll likely find what you're looking for there. Lots of user experiences and good indicators for how much battery life you can expect from the various 2016 Pro models. :)

    The brightness on the 15" is less than the 13" so maybe OP whats to crank it up to 13" levels.

    From here:

    "Up to 10 hours of battery life 4"

    4 Testing conducted by Apple in October 2016 using preproduction 2.6GHz quad-core Intel Core i7-based 15-inch MacBook Pro systems with a 256GB SSD and 16GB of RAM; preproduction 2.9GHz dual-core Intel Core i5-based 13-inch MacBook Pro systems with a 512GB SSD and 8GB of RAM (wireless web test and iTunes movie playback test); preproduction 2.9GHz dual-core Intel Core i5-based 13-inch MacBook Pro systems with a 256GB SSD and 8GB of RAM (standby test); and preproduction 2.0GHz dual-core Intel Core i5-based 13-inch MacBook Pro systems with a 256GB SSD and 8GB of RAM. The wireless web test measures battery life by wirelessly browsing 25 popular websites with display brightness set to 12 clicks from bottom or 75%. The iTunes movie playback test measures battery life by playing back HD 1080p content with display brightness set to 12 clicks from bottom or 75%. The standby test measures battery life by allowing a system, connected to a wireless network and signed in to an iCloud account, to enter standby mode with Safari and Mail applications launched and all system settings left at default. Battery life varies by use and configuration. See www.apple.com/batteries for more information.

    Always gotta read that fine print.

    So 3 out of the 4 tests or 75% were on 13" why did apple do that? to 'massage the figures' hope not.

    Just out of curiosity what happens if you do the above? does the SSD become removable? ;)

    Battery life varies wildly with use.

    I hit 10-12+ hours on my 2015 13" machine regularly. It is rated for 9. If i am trying to run a game I'll get far less. My 2011 15" machine was rated for 7 hours. I could get that, sometimes. Run a game and it dropped to 45 minutes with the discrete GPU active and working hard. This sort of variance applies to any portable, not just apple. Apple's test conditions are actually somewhat realistic though for "work" use.

    Apple's battery life is pretty much the best on the market, real world. If you need a machine in that sort of size/spec and want to run macOS you don't have any other option anyway.

    • Do you really need one
    • Bearing in mind SSD AND RAM is soldered have you got the Spec in mind that you would expect you will need in 3 years time
    • are you taking out apple care to cover problems for 3 years
    • how long do you expect to keep it for
    • what are the main uses
    • will the rMBP be moved a lot ie ruck sack, Uni/College or case on business

    Mine is giving me 6-7 hours on normal Browsing in Safari. No tasks in the Background what so ever. You will not get 9-10 hours.

    You probably won't get 9-10 hours of life. More realistic would be around 7-8 hours I would suspect, depending on what you do (less if you do more than just light work). If that's an amount you can live with, then go ahead and get one.

    And people here said they would gladly sacrifice battery life for more RAM. My 2013 rMBP only gets 45 minutes of battery if it is in the middle of a FCPX export. I would prefer longer :(. My battery passes all tests and it can get even 11 hours of battery with everything off/low brightness and watching an iTunes movie (did this when we lost power at night one time).

    My understanding is that spotlight indexing does not run unless it's plugged into the power outlet

    I have not seen 10 hours yet, not even close. I've been running it against a 2015 and it's about 25% battery doing the same tasks

    I'm happier for a thicker laptop to be honest .....16 or 32 GB ram.

    Today I saw another 2016 15" rMBP with a fully charged battery 100% just showing 3:05 Hours of battery.

    Notebookcheck got 602 minutes of WiFi browsing and 516 of video playback, which is better than the competition in the same category.

    is that for the 2016 15" rMBP that you are talking about ? The one that I am talking about I saw it in an Apple Store.
