    8-10 hours is a piece of cake. I'm constantly amazed but the battery life.

    Certain programs or tasks cam drain it quickly though. Keep an eye on your energy performance in activity monitor to see if something is using more than you would expect.

    Half to 3/4 usually. Sometimes it goes brighter, but usually no more than 2 notches down from the top.

    I get a little over 10 hours in some cases. I can literally use this Macbook from the time I wake up, till the time I go to bed, doing some web development, and listening to music, without an issue.

    What is there for him to prove? If you want to see a MacBook get 10 hours of battery life, or in some cases more, you are more than welcome to come sit next to me for 10+ hours while I type away. I have never used a machine that got better battery life than this one.

    I use the MacBook mostly for Office 365, Citrix, Safari internet browsing, WhatsApp, iMessage, Remote Desktop and some light Photoshopping and I get between 8 and 12 hours of battery life. For me the simple "proof" is that I often go to a clients location at 9 in the morning and leave at about 7 in the evening and I still have 10 to 20% battery left (in some rare cases even more than 20%). Sometimes I make it till almost 9 in the evening too with 1 or 2% left.

    I have the brightness set to 50% and sometimes below and it makes a huge difference it seems. There was a period after the High Sierra update that I would only get about 7 hours every time and I blamed the update for it. I found out that my brightness automatically kept jumping to 100%, so when I found that out and changed it back to 50% it immediately went back to 8-12 hours. The screen seems to be the big battery killer (or if you have some rogue app like my colleague has with Amazon Drive draining his battery).

    Considering I'm not the only one getting this level of battery life, "proving it" seems pointless.

    How would you suggest I do that?

    I am doing the easiest thing possible and showing how I used it today in the activity monitor.

    Unplugged from power at 7am > used it mostly non-stop from 9am to 3pm (which included a 2 hour gotomeeting with audio and screenshare > then usage for another 1 hour+ while rocking 100% brightness at the moment (not for the whole day though). Sitting at 28% battery after all that.

    The time remaining has actually gone up from 1:42 on that screenshot to 1:53 while I typed this.

    Not plugging in for a whole work day(plus some BSing time at night on this forum) is a wonderful thing.

    I seriously dont know how you guys score 10 hours. I hardly ever manage to squeeze more than 6 hours of real-world workflow usage (internet browsing, YouTube, Facetime calls, PhotoShop, GoToMeeting screen sharing, web designing, etc) at 60% brightness.

    So... 10 hours, for my type of computer usage, is simply impossible.

    Is energy impact accurate ? Mine says Safari is 10.4 energy impact and 40 Average energy impact.. is that average ?

    Adobe products will most likely be responsible for that result.

    I'm no power-user, or wizzard, and I'm not unplugged much, but... (2017 MB pro 15") I was only getting 2-2.5 hours just typing. I looked into my use stats and saw that all those tabs I leave open (10-20) in Chrome was the problem. Adding a Suspend Tab App to Chrome totally fixed the situation. There are still times the battery gets sucked dry in a couple of hours and other times it's good all day.
    The Suspend Tabs app just makes the pages go gray, they quickly reload only when I select that tab and click again (anywhere) to reload.
    I think this falls under the general category of SOP-Apple-non-help. If you don't have a problem you don't pay any attention to it, if you do have a problem you get information from two sources 1. Gee, I don't have that problem or 2. I have that problem too, any idea how to fix it? Often as not the #1s have a setting that took care of it and they don't think about it and the #2s are reading stuff on the Apple Support Community that say things like, "oh your AA batteries are too short." (Actual top advice for MagicMouse 1 problems)
    So I'm sort of #1.5 because I have the suspend tab app, but don't know what it's specific name is. But my experience is it doesn't take much to completely change your battery usage, for me it was mostly the internet (too many tabs), and what's nice is that the charger seems to charge it up likety-split.

    Yeh light usage with 70% brightness can get 10 hours. I use Safari as my web browser as it's a lot more efficient than FF or Chrome on this.

    I’m getting about 7 hrs give or take. Light use streaming and browsing but I’m always on max brightness and lighted keyboard. I can’t stant 50% brightness.

    I'm getting 9-11 hours easy. My workflow consists of the same light tasks you all mention above. However in my experience, if I frequently visit sites that have a lot of ads (forums for example) I'll see a dramatic dip in battery life and the MacBook starts feeling warm.

    I had the same question and finally wrote an application that calculates the running time. Later, the ability to collect statistics was added. Among the 40 MacBook models, there are no models that could last on the battery more than about 8 hours (average)

    As mentioned earlier, it is all down to brightness setting in my experience. I usually have it at max and get typically 5 hours continuous use. At 50% I can get 10 hours.

    I get 10 - 12 usually unless I'm doing something intensive like video or 3D work. 3D work can eat my battery up real fast (obvioulsy).

    Well, it depends, really.

    If I'm working on documentation, I get 9 hours easily even when there are occasional bursts of max brightness.

    If I'm browsing the web a lot, looking up documentation, testing codes, compiling, etc... then it's about 5-6 hours realistically. But the same tasks on a MacBook Pro 15" would barely last 4 hours, if even.

    Last use case is if I'm sitting on a plane and all I'm doing is either read a book, write some documentations, or play some light games at 10% or less brightness, then the Macbook has lasted me through the entire flight, which is 12-13 hours. Take away 2 hours for take-off/landing and you get that 10-hour estimate. Not too shabby.

    Does Apple State what brightness setting to put to get the advertised battery life?

    In our experience, Cisco AnyConnect Client kills the battery.
    No way to get 10h with the AnyConnect Client running.

    Hmm im not sure about this battery life issue.

    I generally get the feeling that its hard to push many Mac machines over 8 hours and it's hard to dim a screen when you are working on something like word.

    I also find that even plugging in an external drive [usb c] can really hit battery life.

    I think I use my devices differently. I don't know how much I get. I've never hit zero on my iPhone X or my MacBook. Phone for example, plug in in the car, when I do my morning routine. Never at 100% never below 40%.

    Kinda same with MacBook. If I use on couch at night, I will charge to 100%, then When I throw in BP in the morning and head out, never need to charge till my night time browsing, only because I'll need it the next day.

    Now, my iPad Mini 2 used to get 10 hours, I get about 3 these days.
