Apple Removes the 'Time Remaining' Battery Indicator In New macOS Update (loopinsight.com) 164

Apple has removed the "time remaining" battery life indicator with the new macOS Sierra update following complaints from several users of new MacBook Pro models. Apple says it stands by its 10-hour battery life claim in the new MacBook Pro models, and adds that the battery life indicator didn't show accurate information. From a report on The Loop: You can still see the image on the top of the screen, and you can see the percentage, but you will no longer be able to see how much time is remaining before your battery dies. [...] Apple said the percentage is accurate, but because of the dynamic ways we use the computer, the time remaining indicator couldn't accurately keep up with what users were doing. Everything we do on the MacBook affects battery life in different ways and not having an accurate indicator is confusing. Besides the apps we are working on all the time, there are a lot of things that are happening in the background that users may not be aware of that affects battery life.

        I used to work at a place where if you put an "Out Of Order" notice on something they'd fix it by removing the notice.

        We (well I, they volunteered me because I used to work in a bar) once changed a water container (after waiting four hours for maintenance to do it). Fuck me, the song and dance they made how it could have caused a disaster and so on.

        I will add that, unlike them, I did it properly; I peeled off the hygiene seal rather than leaving it in place so it got rammed inside the container by the spigot. Cunts.

          I used to be an operator on a Burroughs B4700 mainframe (which shows you how old I am). It used to blow these 100 amp fuses in the power supply cabinet periodically. We'd call Burroughs, they'd send someone out when they could fit it in their schedule and we'd be down for hours. Finally we found the spare fuses in the engineer cabinet so we'd pop the breakers and replace the fuses ourself. One day a Burroughs FE happened to be in when a fuse blew and we started to replace it when he blew a gasket, telling us how dangerous that was. He proceeded to start changing the fuse but neglected to throw the breakers - and knocked his ass across the room.

          To stay on the subject: the B4700 did not have a battery indicator.

Now problems arise is that it will remind people they have a dying battery ie a battery at 80% of it's life will become 20% inaccurate in measurement, the older the worse, with fixed batteries designed to drive unit replacement, this becomes ever more problematic.

            Literally the only product in the world that has generic replaceable rechargeable batteries, is cars. Maybe this is why car analogies are preferred above all others.

            I mean, sure, some things run on AAs, but AAs are shit, and pretty wasteful of space, and mostly only used in toys and tv remotes. For a while you could get products that ran off NiMH AAs, and included charge circuitry, but not really any more.

        I cant think of a Linux distro that cant do this either (AHCI command if you're not running a GUI, if memory serves).

        This move is more likely to be that they don't want their users to notice that the battery lasts significantly less than the advertised time. Out of sight, out of mind, that kind of thing.

      If anything, it would be misleading.
      Here's an example: I was watching a movie and my laptop's battery was 15%, saying it can still hold for 35 minutes given the current load. So I went back to full screen mode, and less than 10 minutes later the laptop was at 5% so it went into hibernation. I guess some background process decided to fuck with the laptop resources because of "5 minutes idle" or something.

      Light work naturally will show more time left than playing a video game.

      Well that's just it, isn't it? The time-remaining figure, even if calculated accurately based on what you're currently doing still likely bears little resemblance to the actual time you have left before your battery runs out.

      Say I'm editing my source code in a text editor -- zero CPU / disk / network usage, very light load, and so my time-remaining figure is 9 hours.

      Then I decide it's time to do a fresh compile, and my "make clean; make -j4" drives all cores to 100% and exercises the internal drive for several minutes. Now my time-remaining figure is 2 hours.

      Then the compile ends, and the time-remaining figure is back to 8 hours.

      Which of those figures was correct? Answer: none of them was. The only way to get a correct figure would be to predict how many times I'm going to recompile in the future. So why bother making up a number that clearly is not going to be correct anyway? It only confuses the issue.

      • The only way to get a correct figure would be to predict how many times I'm going to recompile in the future.

        Or it could quote you a range: time remaining with light load, and time remaining with heavy load.

      Therein lies the rub. What is "the same way"? Browsing the web can be tricky - some websites are nice and static and use little CPU and give plenty of battery life. Other websites have videos and sound and take more CPU and reduce the time. So "browsing the web" isn't the same way - I may go to YouTube all of a sudden and the battery life will have to drop.

      And that's the issue - there's no point telling the user they have 5 hours of battery life because they'll think they have ... 5 hours of battery life. Then they launch Netflix and watch a 2 hour movie, and expect 3 hours of battery life left, but get awfully surprised when they're down to 1 hour or less.

      Time remaining works well for relatively constant loads - a camcorder recording video can display time remaining when recording because it's all it's going to do. If it says you can record for 2 hours, then it will last two hours regardless of what you're filming. It won't suddenly drop to 1 hour because a kid comes into frame and recording cuteness takes more power.

      The big gripe here is that Apple's 15" 2015 MBP had a 99.5 watt-hour battery (rated for 9 hours wireless web) while the 2016 15" MBP has a 76 watt-hour battery that's rated for 10 hours. The 2015 model came very close to the rated time, which makes sense with its 31% larger battery.

      Apple removing the estimated time, which it's provided for a long time, feels like a really childish response to the backlash they're receiving. It's been largely understood by most that these times are simply estimates based on the recent rate of consumption.

          Because brightness specs could not be easily duplicated by most people, and wouldn't be that good for cross-comparison purposes anyway, because there isn't a correlation from one brand to another as far as energy-usage and the absolute brightness of the screen.

So this isn't something that suddenly stopped working, nor was it some sort of emergency that required immediate action to "fix". But some manager had a knee-jerk reaction in response to some article, and they decided to remove functionality that is decades old.

          Ten years ago, this would have gotten shot down in UI review. It is unclear whether they could have even made such a change in a major OS release, much less a minor bug-fix release, which are supposed to have zero user-facing functional changes except in situations where a feature's schedule slips, and even then, only to the minimum extent required to enable that feature.

  • ...but can apparently predict the time it takes to charge to full. Just updated to 10.10.2 and it is showing the time taken to charge to full.
    • So they can even predict the time to charge the battery to full, when that varies by how you use the laptop? Try flogging the CPU and graphics as hard as you can, and you'll see how much longer it takes to charge from empty to full!

      Nothing to see here, users, move along, pay no attention to the man behind the curtain, listen only to the Great Wizard of Jobs.

        The power sent to the battery is often limited for safety reasons. If the power supply is enough to run the computer at near-peak performance plus charge the battery at maximum rate, then it won't take any longer than if I were to put the thing in suspend while charging.

    Battery life is up! :)

    • This is right. Its the hallmark of a totalitarian regime. Shows that Apple are rotten and will continue to decline.

  • We said courage is removing the 3.5mm headphone jack.

    Now, we ask for so little: We want you, beloved user, to join us: We want you to live. On. The. Edge.

    We want you to stare down at that sliver that's even less than 3.5mm wide: the last remaining hair of your precious: the juice that is about to beat you to the :wq finish!

    Together we will rule the dark side!!

  • I use it to tell me when the damned Government-required anti-virus scanner starts up in the background.

    That's when the time remaining value drops by about half.

      Effing virus scanners. That's why I never use one. The amount of inconvenience you experience daily from them is worse than whatever any virus can throw at you.

    Apple makes more money off their customers when said customers have facebook open than not. Letting them realize the impact it has on battery life is therefore detrimental to profit.
  • Can't fix it? Hide it!

    Love to hear what the Apple apologists have to say about this move. Hey FakeTimCook! Do we "not get" this either? Do we not have enough courage?

  • I feel like every time Apple scratches their collective butt that there is a post about it on Slashdot.

  • Since they are so sure that their 10 hour battery life estimate is correct, then there's no need to estimate battery lifetime in real-time, they can just start a simple 10 hour countdown timer when the laptop goes on battery, then the user knows exactly when their 10 hours of battery life time expire. If it's a little inaccurate and the user gets more than 10 hours, they can just call it bonus time.

  • "We are allowed to guesstimate battery time for our advertisement campaigns, but you are left to guess what those means".

    I mean, I get it... they need to put some number in the ads. But I have to thank reviewers with consistent methods to know how long devices will last on a single charge...

  • I'm sure the general population is much too ignorant, but why don't they allow a battery gauge that shows actual electrical consumption in actual electrical units?

    It makes sense that time remaining would always be misleading (and likely gamed by vendors anyway).

    But if you had a 75 watt-hour battery and your gauge was in watt-hours, you'd have a reasonably accurate measure of how much battery capacity you had left.

    Apple is trying to tell you that it can't do a simple algorithm that checks battery levels, draw, etc and produce a decent, semi-accurate time remainder on battery life?

    Get the fuck out!

    This is what they get for sweatshopping their code to China and India.

    • by joh ( 27088 )

      This was exactly how this worked up until now. You got a semi-accurate time of battery life. But the remaining time depends on what you do and the dynamic range between "hardly any load at all" and "full throttle" gets bigger and bigger. Which makes the time more and more pointless: If you just sit there and type you get a very long remaining time which will shrink down to a fraction of that as soon as you start to do more demanding things.

      This is true for all modern computers with some decent power managem

    Apple won't be happy until the UI is dumbed down so all you have is a window with one "buy" button to click. There will be no description or specs or anything but just a photo of some sort of thing they pretend is a gadget but is really just a useless block that looks cool. It too will feature just a touch screen with a single "buy" button so you can buy additional proprietary charging cables.

    And Macinmaniacs will still buy them.

  • And replace it with any of the battery tools available there for years, most of which replace the default Menu Bar Icon indicator anyway. I have been using https://itunes.apple.com/us/app/battery-monitor-health-status/id836505650?mt=12 [apple.com] for a couple of years now. Oh look, there is even a 5 star review headlined "Very accurate time-remaining ".

    Laptops, tablets, and phones never seem to know exactly how many hours of power they have left. The estimate may jump from two hours to five hours before dropping back down to one hour. Even worse, the battery may suddenly die without warning.

    Remember kids, this is only a problem for Apple.
