Apple Warns You When Your Display is Using Significant Energy in Latest macOS Beta

    Apple advertises that the latest MacBook Pro models provide up to 10 hours of battery life on a single charge for web browsing and iTunes movie playback, but a user's mileage may vary based upon factors such as display brightness, which apps are running, and external devices connected.

    For this reason, Apple lists apps using a significant amount of energy under the battery menu in the macOS menu bar. The feature enables users to monitor which apps are drawing a lot of power and impacting battery life, whether it be the built-in Spotlight tool or a power-hungry web browser with several tabs open.


    Now, Apple has gone one step further and expanded the feature to include display brightness. On the latest macOS Sierra beta, when a Mac's display is set above 75% brightness--or at least 13 out of 16 notches--a new item called "Display Brightness" is listed under the battery menu.

    Clicking on "Display Brightness" lowers the Mac's brightness to 75%. Likewise, when we updated a new MacBook Pro to the fourth beta of macOS Sierra 10.12.3, the display's brightness was automatically lowered to 75%. This is the same brightness level as Apple used during its latest MacBook Pro battery tests.

    New: "Display Brightness" is now listed and "Apps" has been dropped from the title

    Battery life on the latest MacBook Pro models has been a controversial topic since the notebooks launched in October. A subset of users have reported getting as little as three to six hours of battery life on a single charge, sometimes even with only basic web browsing and other non-intensive tasks.

    Apple has consistently stood by its advertised battery life for the latest MacBook Pro. It did, however, remove the "time remaining" battery life indicator on macOS Sierra 10.12.2, noting the estimates "couldn't accurately keep up with what users were doing" because of the "dynamic ways" people use their Macs.

    Consumer Reports initially failed to recommend the latest MacBook Pro because of battery life inconsistencies, but it later worked with Apple and learned that a Safari bug triggered by its own testing configuration was to blame for the mixed results. Apple fixed that bug in macOS 10.12.3, and Consumer Reports has since reversed course and now recommends the latest MacBook Pro after retesting.

    The new feature is currently limited to beta testers. It will be widely available when macOS 10.12.3 is officially released over the coming days.

    Battery life of ten hours if you cripple performance and dim the screen.

    Battery life of three hours under normal usage.

    Leave the MBP a few mm thicker and battery life wouldn't even be a conversation. Foolish obsession with thin.

    MacOS (Unix) has soo many options for throttling, scheduling, killing misbehaving apps that it should handle those more intelligently.
    Just make an intelligent UI with different settings, warnings, schedules etc.
    (or consult Redmond...)

    Interesting... Now if Apple could bring back the time remaining section back to the battery menu, that would be great. Yes, I know it can be seen in the activity monitor, but it's much more convenient to have it right in the menu bar.

    Came to MacRumors at 1 PM EST to see a post about iOS 10.2.1 dropping. Disappointed with my findings.

    I don't like setting my display to less than 100% bright most of the time. I think most people feel the same way. Using 100% just seems good.

    Apple should rename 100% as 130% and scale accordingly. It sends the message that, though your screen can go that bright, you shouldn't set it that bright unless you really need to.

    There is a way. Snazzy Labs on YouTube just did a video on it actually. I did it on my MacBook Pro and it worked like a charm. Just look him up, it's his most recent video.

    It takes a lot of courage to tell me I chose an excessive screen brightness.

    My sentiments exactly, I am still hopeful of that Theatre Mode and MacRumors trolls me by posting a new article at that exact time :p

    still not resolving the harware issue with the new mbps. The batteries are insufficient.

    Apple has to manage to the lowest common denominator of users - so there are enough people who don't understand that things like cranking the screen brightness, keyboard backlight and running flash video on Youtube will have a negative effect on battery life.

    The batteries are not flawed. They are efficient and capable of 10 hours of life. Clearly, any intense task lessens that charge length. Apple is fixing the software issues that led to inconsistent battery life. It wasn't hardware related, which is obvious when you look at how inconsistent the battery lives were.

    This comment reminds me of the "Turbo" switches on older x86 PC desktops/towers from the mid to late 90's. As if anyone ever ran their PC in non-turbo mode, but hey if anything goes wrong we can blame it on user error. "You're running it too fast!" LOL

    In other words, Apple points to everyone else for their poor design choices. Typical Apple, always blame everyone else.

    If users left the lid closed and the machine powered off, the battery life would be even better. Then they could spend even less putting costly batteries in them.

    Do people really use their laptop screens at 500 nits ALL the time? This seems unusual cause I would think 350-400 nits is more typical for daylight hours.

    Lots of people ran in non-turbo mode. Some IBM PC/XT software didn't run properly at AT speeds, especially games.

    I will refrain from saying anything. The normal comments should be dumb enough.

    Great. Now if they would compliment this with another item which displays remaining battery time under these current circumstances. All together it could prove a useful feature.

    When I had my 2016 machine , setting brightness above 80% took a considerable hit on battery life. Guess this helps to bring the users attention to the fact

    It's not about "unless you really need to". It's about "do you really want to while you are on battery and need to stay on battery for a while". Most laptops are plugged in most of the time, thus, most of the time, no need to restrict brightness.

    Apple is doing a great job handling this issue, which is nicely reflected in the new Consumer Reports recommendation.
