    Heh. Everyone's an engineeer these days. Anyway, the empty space is probably just the result of the rest of the computer and component space requirements, and the size of the battery is directly tied to the weight. Fill it with battery and the laptop would be heavier, and Apple clearly doesn't want that. That, and your money :) But since they want mine, they prioritized mobility over filling up the entire laptop with whatever.

    Pretty sure they don't want your MBP turning into fourth of July fireworks at the slightest impact.

    That's one of the major reason why Samsung phones are all turning into fireworks.....

    Lol if you call that wasted space, you'll have a heart attack if you take apart almost any Windows laptop. :p

    Last year it was reported, the reason was a failed battery test and they had to revert to an older design.

    In the run-up to the MacBook Pro's planned debut this year, the new battery failed a key test, according to a person familiar with the situation. Rather than delay the launch and risk missing the crucial holiday shopping season, Apple decided to revert to an older design.

    If this explanation was true and I don't doubt that, they've had plenty of time to fix it. Unless they think they have more important engineering tasks to solve than their second generation $1,799 notebook. All they did to address the issue was to remove the 'time remaining' battery life indicator from macOS.

    wrong, the Macbook has a shape design. Remember the reason Note 7 boom boom? same thing as you want, too much battery

    trust me, 2017 MBP with High Sierra, you have 10 hours battery life

    I don't touch them with a stick and I won't pay a premium price for this trash.

    There is a slight difference in the level of strength of aluminum between a phone and a laptop. All Unibody MacBooks are sturdy, nobody ever heard of a 'Bendgate'.

    That's not enough, my 2010 MBP had 10 hours battery life, 11 hours on 10.9 Mavericks. That's the bare minimum, but I want more. And I don't want to see space go wasted for nothing.

    The explanation was not true, as was discussed several times (not that any proof was needed, but the fact that 2017 has the same battery just proves it further). It was false news, simple. A supposed rumor of a rumor, people playing engineers and just another of the many myths. Terraced batteries were introduced in the MacBook so they could fit a tapered body, one that the new MBP doesn't have. Terraced battery would make no sense here, and the reason Apple went with a smaller battery is due to weight (the battery is the heaviest component inside a laptop). CPU optimizations have allowed them to reduce battery size (meaning: weight) without significantly sacrificing battery life. Just as they didn't fill all available space on the iPad Pro with battery, to reduce weight. The first chance they get to reduce it even further and keep this battery life, they will.

    Then don't buy it. I doubt the people at Apple will lose any sleep simply because they didn't get your patronage.

    ahahahha nice try with that MBP from 2010 and 10 hours, maybe not doing anything with brightness at 25%. in this way i think i can get 14-15h from mine...or i can get around 20 hours from a macbook air 13"

    What would you put in this wasted space?

    Tear down you say? Looks like it just has the bottom cover removed.

    Oh... wait, you're deadly serious? I thought your thread was tongue in cheek.

    Honestly the space is extremely efficient, far from 'trash'. As another poster already mentioned, if the battery was right against the case then you risk puncturing it if you drop the laptop.

    Agreed, from that image, I'm baffled at what could go in there. I'm not engineer, and I trust Apple has some pretty smart folks working for them. If they could have made something bigger to go in there they would. Sometimes its not what you put in it, that makes a difference. The samsung battery issue, where one report at them using a battery with no space to expand.

    Nonsense, all the other Apple products, even the latest, are stuffed of battery cells (MB, iPhones, iPads, and so on).
    I do not see why they should start doing this only on the MBP...safety is not the reason.

    The reason is just the asinine run for "thin and light" at the expense of performance (battery life in this instance).

    More battery?

    If they didn't make the trackpad so big I am sure there would be more room for batteries ;)

    What specific tolerances can these batteries handle? Just saying bigger batteries ignores the fact that they need space to expand. I'll be the first to admit I'm ignorant of these details but if you have training in such matters please let me know. I think knee jerk reactions such as make it bigger don't help because a lot goes into the design of these machine.

    Estimated battery life remaining time can be found on energy pane in Activity Monitor. Not as convenient as clicking a menu icon, but it's still available if you want it.

    No they do not, otherwise we will see empty space also on the MB, iPhone, iPad, 2015 MBP. Other Apple devices that use same battery tech do not have it. 2016/2017 MBP is the only one that has this empty space around the battery...

    Batteries have a tendency to swell over their lifetime. It might look like 'wasted' space today, but 5 years from now it could be filled. The important thing is that it could if worst case occurs, not having nowhere to go in a worst case is far worse than having an extra few hundred milliamp in the battery capacity. There's also things like heat dissipation and diminishing returns. Just be thankful they prioritised safety, you might have that laptop for several years after all.

    How do you know it's wasted space? What is your engineering expertise? Just because it's empty space, doesn't mean it serves no purpose.

    I trust Apple engineers in designing the laptop for tight tolerances more than seeing posts on the anonymous internet. To summarize, my opinion is that its not wasted, you disagree, fair enough. Both of us are entitled to our opinions.

    They all have empty space, this is a factor related to capacity. So a larger battery requires/allows for more space.

    Wasted or empty space isn't the right way to think of it, more of a designed void/safety requirement. Not all batteries need it, but over a certain size they require it exponentially. Batteries are also designed and built differently, some have less internal stacking and so have a built in void. Others are more efficiently packed and require an engineered void.

    Either way, just know it isn't Apple's attempt to screw anyone over, and likely we will see larger batteries filling this space in the future as battery technology and manufacturing techniques develop and allow for it.

    Of course the tin foil hat wearer could suggest that Apple had planned on using larger batteries (Which could result in an extra hour) but after the Samsung issue they decided to play it on the extra safe side.
