Brand new 15" Macbook Pro Retina - Battery life only 4 hours, not 9 like they claim

post #1 of 11
Thread Starter 

Hi,

 

3 days ago I purchased the highest end Macbook Pro 15".  The computer is amazing, fast, and light.  However, one of the main reasons I upgraded from my 3 year old Macbook Pro was due to the claim of up to 8 hours of life (using wireless web or itunes).  I am getting a little over half that with just email (Apple Mail program) and Safari open.

 

I've had my computer diagnosed at the Apple store and it checked out.  I've had a couple of calls with their level 2 tech support and they went over activity monitor items with me and tried a bunch of things, but the battery is still only doing about half of what Apple claims.  How is this possible?

 

http://www.apple.com/macbook-pro/specs-retina/      <- see the battery life info. there.

 

Is anyone else having this issue with the newest model Macbook Pro's?

What do you suggest?

 

Thanks,


Russ

I am using it lightly with mainly just Safari and Mail open.  Of course wi-fi is activated, but on Apple's site, they say that the battery is rated at 8 hours for this model with wi-fi use.  Is anyone else having this issue?

Apple never tells you the truth about the battery life in their computers . They always exaggerate somewhat I owned MBP and Airs and I know from experience.

Hi Russ,

 

Not sure if you've been able to resolve your problem, but I was having the EXACT same issue. When I first brought the new Macbook home the battery life was as claimed but after having installed Office Suite, Adobe CS etc the battery life plummeted to only 3 hours on wi-fi even if I was only running a browser and Skype.

 

I was about to take it back to the Apple Store, but decided to try a few settings changes first and the incredibly simple thing that worked for me: Under energy saving preferences I checked the box to activate the "Power Nap".

 

I now easily get 7+ hours on wi-fi (on my 2.6 ghz model they only claim 8, so close enough!) while running multiple browsers, Photoshop, FTP etc etc.

 

Hope it works for you!

 

Cheers, Julie

Julie,


Wow, thanks!   I just did that and it increased the battery life by almost double.  Thank you very much for sharing!

Hi there, 

I have the same problem and I live in Bulgaria where the nearest Apple Center is 140 km away from me. I have the same early 2013 Mac Book Pro Retina display. But the battery lasts  no more than 2 hours. I use on line video clips, Skype, Video player for movies and browse the Net.... Did you find any solution to fix that. I just click on that Power Nap, and started to pray it will help ....

Thanks

Flash when you view videos takes up a lot of battery usage.What browser do you use?

Hi Julie,
No offense intended, but I'm afraid that by enabling the feature power nap you will achievie the excact opposite. The battery of your MacBookPro Retina 15" will definitely drain faster with this feature enabled. Here's the reason why: While sleeping your Mac executes several tasks in the background when power nap is enabled.
It's easy to comprehend that a Mac that is doing stuff eats more battery then one that is in deep sleep mode.
Please have a look at this website where Apple explains the power nap feature: http://support.apple.com/kb/ht5394
"About Power Nap

While sleeping, Power Nap allows your Mac to do things like periodically check for new mail, calendar, and other iCloud updates. When plugged into AC power, Power Nap can also perform things like Time Machine backups to an AirPort Time Capsule and download OS X software updates while your Mac sleeps.

When your compatible Mac goes to sleep, Power Nap still works to do the following:

Mail - Receive new messages.
Contacts - Your Contacts update with any changes you may have made on another device.
Calendar - Receive new invitations and calendar updates.
Reminders - Reminders updates with any changes you may have made on another device.
Notes - Notes updates with any changes you may have made on another device.
Documents in your iCloud account - iCloud pushes any edits you made to a document to your Mac notebook.
Photo Stream - Your Photo Stream updates with new photos from your iPhone, iPad, or iPod touch.
Find My Mac - Locate a lost Mac notebook even when it’s sleeping.
VPN on demand - Corporate email updates securely.
Mobile Device Management - Remotely lock and wipe the computer. ..."
That's the reason why power nap is disabled by default when you are using the MacBook on battery. It must have been some kind of wishful thinking that you thought you retina MacBook would last hours longer with power nap enabled. I'm sorry to say that this is absolutely impossible.
[cheers

Hi Vincent,

 

I'm not sure the point of your post as you don't offer any alternative solution to the problem, or even an instance of this solution having not worked, which could have been helpful for some users (eg. maybe it depends on what software you've installed etc), but merely your theory on why it shouldn't work.

 

I'm not an expert, so I'm not going to bother disputing your theory, but what I do know from actual first-hand experience is that this is neither "impossible" nor "wishful thinking" on my part.

 

Before I changed that one setting--and ONLY that one setting--the battery life on my brand new Macbook was abysmal, and afterwards (and still today nearly one year later) the battery life is as promised by Apple.

 

No offense intended, but frankly I don't care what settings you prefer to use, activating the power nap worked for me so I thought I'd share the tip in case it might help other users. It seems to have done the trick for the original poster.

 

Cheers, Julie

 

ps. If you somehow thought that simply disputing the solution would be helpful to other users, a more polite and less arrogent way to have made your point would have been to say something like, "That's interesting that this seems to have worked, are you sure you didn't make any other settings changes that could have accounted for the improvement because it doesn't make sense to me. My understanding of Power Nap is....."
