Senior Apple Advisor admits that MBPs have battery issues

It seems to me that with the battery sized the way it is now, at 49Whr in the TouchBar model, 10 hours of battery life doesn't add up except under the lightest of usage scenarios. I'm sure that the efficiency of some components has been improved, but I'm skeptical they've improved them enough.

My 2015 rMB typically uses between 4-5W under light use, at ~60% brightness. With its 41Whr battery that's good for over 8 hours of use even at 5W. The new MBP has a larger, brighter screen, a much more powerful processor (28W TDP vs. 4.5W TDP), two fans, the TouchBar hardware, and two Thunderbolt daughter cards, among other things. So with all those additions, it needs to use the same 5W as my rMB in order to hit the stated 10 hours of battery. Seems unlikely.

Simple fact as you pointed out, its cannot.

I'm using a 2015 2.8 Refurb and 2016 2.7 to decide which one I want to keep, and testing both, doing some heavier tasks such as video encodes, the new machine is some 25% worse battery wise. So far in my opinion , lovely machines, but apple has dropped the ball in regards to battery life. I am sure you can squeeze 10 hours out of the new machines, but you need to baby it....

Well....there's your problem. Give it a few cycles.

Can I ask why? Everyone always says indexing etc, indexing does not happen with the power supply disconnected , and also battery life does not change from first cycle , the only thing that changes is the battery life estimator, unless you just use your device for light use, if you mix your usage, the estimator is just just a rough estimation.

Actually, batteries do reach their maximim capacity after a few cycles.

is this a fact or an urban myth? Personally I have noticed significant changes in the estimator but not the battery life. Also everyone is installing software in the first few cycles which is CPU intensive so people would assume battery life is worse.

It's thinner. That IS what you wanted after all right?

Yes

How about current design, last year dimensions and ports. The best of every world. I don't think any one was complaining the rMBP was too heavy or too thick, I still consider my 2008 unibody thin.

That would get you even less battery life, considering how much space things like the SD card reader, HDMI, USB-A ports take up.

how long are they making you wait for a new one? definitely let us know if your issues are solved because I want to know if it would be worth it to send in.

Apple told me that everyone that changes their mac because of hardware issues gets infront of the line and actually joins a different que then the ordinary one. They but you in the defaul que when you Call in, and when they get Your old mac they bump you over to the prioroty que. I am going to get a estimate when they get mine, sendt it in yesterday. Her Guess was 2-3 weeks.

Will let you know when i get the final shipping date.
 
For those who are receiving a replacement, how much battery life were you getting on average?

After a few days of usage I seem to be getting around 6 hours battery life maximum when surfing the web, listening to music or watching movies.

I will get back to you after I get my replacement.

The one I sendt in gave me aprox 2-3 hours of battery life when using safari. I also hade problems with the graphics and pad.

I think this is all software related, but still. Better safe then sorry. Lets see what happens this time.
 
My base model 15" MBP is on the first battery cycle and seems to be good. After 6 hours of use the battery is at 46%. I'm not doing anything heavy duty - just surfing and e-mail/texting and installing a few things like flash player and printer.
 
So, does this mean that the next MBP will have even fewer ports and RAM to make the battery life better? (joking)
