"The 13-inch model without a Touch Bar had an average battery life of 18.75 hours, the 13-inch model with a Touch Bar lasted for 15.25 hours on average, and the 15-inch MacBook Pro with Touch Bar had an average battery life of 17.25 hours."

Uh ??

Yah definitely trusting Consumer Reports.

Apple does not pay enough to get 48 hours battery life ?

Shame on apple. Poor Marketing
 
It is easy to blame CR here but I think the bigger question is why can the Safari Browser be affected in such a way to have such a negative impact on the battery life. A simple cookie used by CR should not have killed the battery that easily that this speaks more to the holes in the Apple software vs the holes in the CR testing process. CR does a good job testing but they cannot be aware of every odd memory leak or security hole apple may have left in their software.

CR will also not be the first person to accidentally use whatever cookie or setting so grossly affected the MBP. Apple needs to make it so such a simple thing will not have such a negative impact on battery life.
It was a bug. Apple admitted that it was a bug. Apple also said, correctly, that CR's decision to disable caching - which has nothing to do with cookies inherently - is not representative of typical user behavior. CR should indeed be aware of the defaults given that they change the defaults
 
Apples software really isn't up to scratch anymore. At least this is fixed now but it doesn't tell the story for Chrome users.


First off Chrome is Googles issue not Apples...And Apple software is some of the most well written software known to mankind! Honestly how anyone can use MacOS and not see the HUGE differences between it and windows is beyond me.

I am fascinated daily when I use my MBP how well everything works and how well the software controls the hardware. THAT is the difference between Apple and everyone else. Had this battery issue been a Windows issue it would never have been fixed properly and they can't send fixes like Apple can because the OS is on so many different types of hardware. I couldn't disagree more this your statement, the software is second to none.
 
Funny, I read soooo many replies here from people saying "CR doesn't matter, apple doesn't care" blah blah

Then why did Apple work with CR ? Hmm?
 
It was very unprofessional of CR to release the first version of the review, where it was obvious that the results were not representative. But 15+ hours? Come on... Thats just as ridiculous... only shows that their test is unrealistic.
 
Smells like an emissions test scandal. Either they paid Consumer Reports a hella bunch to lie, or they wrote software that cheats battery tests. ;)

I do not believe this looks good for Apple. The better option would have been to accept the initial results. This sudden U turn looks very, very suspicious.
Um, what? How does this look suspicious at all? Apple's testing process is different from CR's. CR changes some defaults to standardize their testing process across machines and Apple sticks to the defaults. They got different results. Apple asks CR to hare their testing process and as a result discovers a bug in Safari that when fixed improves the battery life. CR even admitted that when they used the standard defaults, the battery life was in line with Apple's battery test results. They didn't write results to cheat battery tests, they wrote mostly working software which had a bug that would not normally occur.

As someone else pointed out, CR's test is meant to be able to compare multiple machines, not necessarily be representative of the normal usage pattern. I've gotten 9 hours before on a 2013 rMBP rated for 7 - and that was w/o dim lighting
 
I love all the conspiracy theories saying Apple paid off Consumer Reports or "broke some legs". It's a simple case where CR tested the product and due to a software bug, it underperformed in battery tests. Apple asked for data and after fixing the software issue, it was retested and CR changed their rating. I love all the conspiracy theories in this thread though, they're funny.
 
Shouldn't they wait to change their recommendation until after the fix is actually released? Average Joe who goes and buys one based on this report will then wonder why it's still an issue for them. No recommendation should be made based on beta software.
That's what I thought to but then remembered that they changed the defaults to break Safari initially, which means that the Average Joe won't be affected

It's a bug related to a developer setting. It's not causing a crash, just some extra cpu work that most people aren't going to notice. This is the definition of an obscure and difficult to observe bug.
 
17.25 hours on the 15"? Insane. Mine has never lasted more than 5 hours. Then again, I'm using (the superior to Safari) Chrome browser. Is it really that much of a battery hog? Like another user posted, I can't even imagine this machine lasting 17 hours with the screen on.

For whatever reason, there will always be people who doubt Apple or who somehow want to see Apple fail.

I'm a happy 2016 MacBook Pro owner who has had pretty good battery life, but certainly not 15 hours of battery!

What the hell is going on here? They went from underperforming to way overachieving. Seems just as unreliable as the initial results to me.
If you remember the initial results, they also included 15+ hours of battery life in some test runs. So what you see here is the removal of the bug that intermittently reduced the battery life significantly from 15+ hours under a light load.

The deeper message here is that Intel and Apple have managed to reduce battery consumption under idle or light load very significantly. Essentially, when not needed various parts of the CPU, motherboard and OS can go into something like a sleep mode. The problem with these advances is that the power consumption in idle mode and under full throttle now probably exceeds a more than 10x differential. This means that actual power consumption will vary dramatically from user to user and application to application. And that any bug that disturbs this 'sleep' has very large consequences. And one might ask whether any real system with many applications and with minor problems accumulating will be highly unlikely to allow these advanced power-saving measures to become active.
 
I don't believe anyone in the market to buy a MacBook Pro decided to buy something else based on that CR report, so I doubt Apple lost any sales.


A lot of people read and rely on CR. Which is why Apple QUICKLY responded publicly and said they are working to a resolution. And they did, which I think is honorable.
