Battery issues on new Macbook Retina 15" Mid-2015 only lasts <3 hours

there are few "make sure its plugged in" level things you can do, then you need more analysis:

• make sure all your software updates have been done. Sometimes firmware changes are introduced that change operating characteristics like battery run time.

• Do an SMC Reset. If you need the procedure, just ask.

• develop the rigor to QUIT Applications you are done with. If you merely close all their windows, they are still running in the background until you quit. This is done so that when you want to re-launch them that will be instant.

Then you need to look for things that might be using more energy that they are entitled to. Activity Monitor now features an "Energy" pane that occasionally provides surprises.

Then run etrechek, a completely non-invasive utility that uses standard system calls to look around inside your Mac. It does not even need to be Installed. It does not change anything unless you ask it to.

There must be another thread on this topic because I'm seeing this thread on July 23, 2017.

I have owned several Macs, including 3 different MBP's, over the past 9 years.

I have never had a battery go down as fast as this one does - not on any of my Apple devices, and

I own iPad Air, Mac Book Pro's, MacBook Air, and have had all sorts of Mac laptops over the years.

I just bought an iMac and a retina 15" MBP (mid 2015 model still) in January 2017. I cannot believe how the battery

goes down on the MBP. And, it is NOT related to Chrome. Chrome was not even open.

I'm running Sierra 10.12.5 and have 16 Gigs of RAM.

The other day, I was sitting with the MBP listening to a financial talk show on the radio.
I ONLY had WORD open, and I was taking notes as I was listening. Nothing else was running except the OS.

And, I was not typing all the time; I'd sit and listen

9:31 AM - 67%

9:43 AM - 64%

9:49 AM - 62%

10:02 AM - 60 %

10:06 AM - 58%

Even goes down in sleep mode.

I see that others have been having this issue for some time. I just purchased my 15" retina MBP this past January 2017. So, this seems to be an ongoing problem. I'm still within my one year warranty, and I have purchased Apple Care.

1) Can anyone tell me if batteries can be replaced in these MBP's?

2) Or, is it the reset issue I'm reading about in the thread?

Thank you,

Grant,

Thank you for the quick reply. I'm up-to-date on updates. I've only had this MBP since Jan 2017, and

I manually do the updates so I can see what it's updating.

Yes, yes, I always quit applications. I have 16 gigs of real RAM too.

1) I have not looked at the Energy Pane. I'll figure out how to do that.

2) I do not know what SMC reset is, but I'll look it up. (I've done PRAM reset before, but not lately)

3) I will use the link you supplied; have not done it yet.

I just wanted to say thanks for such a quick reply. I'll let you know how I make out.

Take a look at this article: https://www.apple.com/batteries/maximizing-performance/

Try these steps: Resetting the System Management Controller (SMC) on your Mac - Apple Support

If nothing helps, I believe you need to contact Apple Support: https://www.apple.com/support/macbook/contact/

Since you have a new MBP, have it checked under the warranty provisions at an Apple store genius bar.

If you purchased it from Apple (not a reseller), you have 14 days from the purchase date to return the MBP for an exchange or a refund.

Note how Apple advertises battery run time: They say UP TO, not WILL last X amount of hours and they use very conservative settings.

Ciao.

Have you actually tried running the battery down to verify the actual run-time of the MacBook or are you just going by the battery gauge?

Hi stazi,

I am having the same problem with my mid 2015 macbook pro 15. Did you solve the problem? Please let me know.

Thanks,

Ming

Same issue... fresh from unplugging and only browsing web - battery est is ~5hrs... guess I'm headed to the Apple Store 8-|

I have the same problem. MacBook pro 15" 2 days old and less than 3 hours battery life. Would love an answer

The answer is waiting for you at the genius Bar. Be sure to make an appointment, or you will be turned away unserviced.

The same issue! SMC and PRAM reset help only for 5-10 minutes and then even I do nothing - battery loose power twice.

10 minutes of nothing and 8:56 become 4:12, and in the fact only about 3 hours in real.problem>

What the problem? What should I do?

Anyone get an answer on this? i bought mine in may of 2015 and initially had great battery life. suddenly my battery life is terrible

I am now on my second MBP mid 2015, after returning one which lost all battery life from 100% to empty, whilst in sleep mode. I now have exactly the same problem on the second unit too. Could they both have been from a dodgy batch? At the moment my iMac offers more portability.
