    I have a 2016/15"/16gb/512/460.
    Currently I'm powering a 1080p external monitor & casually browsing chrome. At full charge, I'm getting an estimate of 3 hours battery life. With gaming its even less.

    Is that a proper estimate, or should I get a replacement?

    This is a real problem. I only get 3 hours of battery time when only using safary.

    Its just a joke paying over 3000 dollars for this machine...

    Yea its ridiculous. I don't understand how some people are getting 9-10 hours of battery life...

    We ignore the battery life estimate, and just use the machine. It seems to last a lot longer than estimated.

    I have the base 15"... when I first turned it on this morning after a full charge to 100% I said that it would last just over 3 hours. I haven't charged it since this morning and am getting a prediction of exactly 3 hours at 37%. Its only been light use but the battery prediction changes constantly depending on what you are doing.

    I have a 2015 max MacBook pro and the same model as you.

    Decided to get both to 100% battery , disconnect and run handbrake on each to see what they would do when pushed to.

    Handbrake finished on both .

    2015 : 50% battery life left
    2016: 26% battery life left

    2016 is worse, by some margin. Apple claims they are the same, no they are not, both pushed the 2015 is superior .

    Sure you can get 8-9 hours out of the new machine , though you will be doing intensive facebooking, twittering, web browsing , some videos etc.

    Mind you those 8-9 hours are battery estimator numbers, I get those too....those mean little when I push the machine and see 4 hours.

    Use it for intensive CPU and GPU tasks, and the battery drops fast.

    This is unusual . How many cycles ? Your brightness ?

    People will says it's cause finder is indexing etc....though that's not true, when the power is not plugged in, indexing does not happen.

    Ignore the battery prediction....it's useless. See how much you get actual usage out of a charge

    It was only a matter of time until the thinness hit battery life. It's already stripped ports and power.

    Just wait until the screen gets paperthin and floppy.

    The battery indicator has been pretty accurate so far.
    So far I've lost 30% in 30 minutes. Just from web browsing.

    Low keyboard light, 75% screen brightness.

    Full spec 13" (i7/512/16) and I'm getting pretty much what everyone on this thread is getting. 4ish hours. Nothing heavy, no video rendering. Browsing, some videos, etc. Not thrilled.

    Just as a FYI.... Using a Late 2016 stock 13-inch rMBP without Touch Bar

    I ran a heavy workload which drained the battery down from 100% to 1% after some 2.5 hours of use. If anyone intends to heavily use the 13-inch non-Touch Bar model during a normal 8-hr workday then they will need to charge once or twice during the daytime for sure.

    My workload was

    1) Continuous read/writing to the internal SSD. During the 2.5 hrs I read 3.5 TB and wrote 3.5 TB of data. I used AJA to do this.
    2) I ran several Terminal commands in background in continuous loops performing 'finds' and 'ls' commands. There was a 2 sec sleep between each loop.
    3) I ran four GeekBench 4 runs.
    4) I ran a single pass of memtest.
    5) I had Activity Monitor running all the time.
    6) I periodically used Safari, Messages, Calendar, Calculator, Maps and had Time Machine on auto mode running.

    Although the 2.5 hrs on battery was a bit disappointing, I have to say I was very happy with the fan not kicking into high gear. It only reached a max of around 4200 rpm (the max for this MBP is 7200) at times and to my ears the MBP was very quiet throughout the 2.5 hours.

    Hmm i think it just me that have poor(?) battery life on this new rMBP after used it for 5 days.
    My machine, base model 13" with TB, macOS Sierra 10.12.1.

    Here's my special experiment for test my rMBP battery life.

    Activity Monitor

    The machine was idle, good news. I just opened 4 tabs. Apple support, homepage of macrumors, and two tabs macrumors forum (this thread and another thread about Battery Life too!)

    Oh please, this piss me off. I expect good battery life on this machine :(
    My intensive task was just programming or photo editing (Photoshop)
    I am really newbie on mac environment, many years ago stick with Windows and Linux. So this is my first mac machine.

    And then, my special problem is in my country (Indonesia), this machine will go on sale officially sell next year.
    I don't know if I can return for replacement when it comes official to my country :(

    External monitors always trigger the discrete gpu. 3 is pretty good running one of those. My 2015 gets about 60-90 minutes when gaming.

    Try unplugging and not using chrome. How's the battery life with safari and nothing plugged in?

    13" TBMBP i7 3.3 16GB 512GB

    Updated to latest 10.2.2 Beta.

    SMC Reset. PRAM Reset.

    Set Keyboard backlight - 1 click

    Set Screen Brightness - 12 clicks

    Set Volume 50%

    Finally the rapid percentage drop rate of the Battery I was getting has slowed dramatically. Too early to say but possibly around 8.5-9 Hours now on normal usage tasks.

    Dropping 1% about every 4-5 mins. Still not ideal but a lot better.

    Really? You're powering an external monitor at 1080p on battery power? Are you a millennial?

    Seriously. Reading the OP: *facepalm*. Chrome is a massive battery drain as it is hardware accelerated. External display and gaming? You are certainly keeping the GPU engaged. ANY laptop battery will suffer under that type of usage. Why the hell not plug it in? There is nothing wrong with the Macbook. I had this happen on my mid-2012 MBP. Use of Safari instead of Chrome always resulted in near spec battery life. Chrome always caused my battery to tank. Thats not a Mac or OSX issue, thats a Chrome issue. The browser needs to be made more efficient.
