Macbook Pro 11,3 High End Retina battery capacity

HI,
As recent as 2 weeks ago I receieved a macbook pro that I purchased online. However due to the physical problems I had another one sent to me by apple. While waiting for the shipping company to pick up the problematic macbook pro I thought I'd compare the battery life on both of these units. to my suprise the old unit was performing better in terms of battery life.
New Macbook Pro 11,3 Capacity: 8688 mAh
2 Weeks Old Macbook Pro 11,3 Capacity: 8969 mAh
My questions are as follows:
1) Is this to be expected?
2) Should I complain and get it replaced again?
3) Anything I could do to increase the capacity on the new MPR?
Appreciate your input on this, cheers!
Happy holidays!

Great to hear :) I was really worried about my battery capacity as well when I got my 2nd mac.
The reason I exchanged my first one was it had really bad battery life. I tried all sorts of solutions and nothing seemed to work. It would always show I had a high battery capacity but the battery life was just terrible. I decided to exchange it and when I got my replacement I noticed it had low battery capacity. It turned out to be a great laptop it has much better battery life and it's capacity went up after I put a couple cycles on it.

Is standard Macbook pro slower than the MBP Retina

Is standard Macbook pro 13 with i7, 8GB RAM, going to be slower than the macbook pro retina?

farooq_opf,
the higher-end non-Retina 13-inch MacBook Pro comes with a 2.9 GHz Core i7 CPU. The higher-end Retina 13-inch MacBook Pro comes with a 2.8 GHz Core i7 CPU. Both of these models are dual-core CPUs. The 15-inch Retina models have slower, quad-core CPUs. Whether the higher-end non-Retina dual-core CPU or one of the Retina quad-core CPUs is faster depends upon the particular task that you’re trying to do; for tasks that lend themselves to multithreaded processing, the quad-core CPU will probably finish faster, despite having a slower CPU.

Dreamweaver

bare in mind I will upgrade either to 8gb ram and 256gb SSD

Hi Bainze,
I would get the 15" Non Retina because of the 'anti-glare' option but in the end the decision is really up to you.

Macbook Pro 15in mid 2012 Non-Retina Freeze

Macbook Pro 15in mid 2012 Non-Retina Freezes randomly. OSX 10.7.4. Do not have Google Chrome installed. I have to press the power button to restart. Any idea how to fix this?
When ever the computer restarts it looks like this:
http://i45.tinypic.com/2mrin7t.png

I would like to share my experience with the random freezing on my brand new Retina MacBook Pro.
This may apply to non-Retina and MacBook Airs, too.
My rMBP had randome freezes; seemingly starting from Safari, then spreading to the whole system, refusing to launch programs, etc., forcing me to restart every 1-2 hours. There was just no other way to come out of this coma other than forced rebooting.
Tried all the usual recommended remedies, but nothing worked. It's been about 2 weeks like this.
Then I remembered from my past experiences that with every new hardware there seemed to be issues with graphics card/driver. I did the following and so far I havent' had a crash for 24 hours and counting.
1. Turn OFF "automatic graphicss switching". You can do this in System Preference>Energy Saver. It's the top tick box. Untick for both AC Power and Battery Power.
2. Turn OFF "automatically adjust brightness". System Preference>Displays.
Can't tell if it's the combination of the two or one effecting the other, but seems to work!
I have a feeling it's the "automatically adjust brightness" could be the culprit.

What is the best way to use a macbook pro? Plugged in or on battery?

Is it better for the computer if you use it while it is plugged in or to use it on battery until it needs recharged and then recharge it all the way before using it again? Which way is it better for the computer in the long run?

It doesn't really make any difference unless you don't really need to use it on battery power. Use the battery when you can - when you are mobile. Otherwise, use the charger.

Is there an adapter to hook up a firewire from a cannon gl2 to a MacBook Pro? The firewire end is too big to fit in the MacBook Pro laptop help.

Is there an adapter to hook up a firewire from a cannon gl2 to a MacBook Pro? The firewire end is too big to fit in the MacBook Pro laptop help.

After identifying the exact connectors you need, check the Apple Store online and/or eBay...you should be able to buy a cable with the correct connector on each end, rather than fooling with an adapter.

My Macbook Pro is not charging eventhough the battery is 95%, Is it not working ?

Will my 2009 macbook pro support a higher operating system than OS 10.5

Will my 2009 macbook pro support a higher operating system than OS 10.5.8?

For any upgrades, you will need to purchase this Snow Leopard disk from the Apple online store:
http://store.apple.com/us/product/MC573Z/A/mac-os-x-106-snow-leopard
After installing Snow Leopard (10.6.3) you should perform a software update and install 10,6.8. That will permit the installation of either Lion, Mt. Lion or Mavericks, depending upon your needs and/or preferences.
Ciao.

13' MacBook Pro i5 dual core(non retina) vs 15' MacBook Pro i7 quad core(non retina)

I'm looking to buy a laptop, I'm going to use it for some photoshop, and daily use of excel,iTunes,web browsing, watch videos. The following laptops are which I'm looking at: 13' MacBook Pro i5 dual core(non retina) and 15' MacBook Pro i7 quad core(non retina). Please let me know what you suggest. I'm looking for a laptop to last me at least 5 years.

I'm trying to stick w/o having to buy the super drive and need a lot of memory to store so that's why the retina laptops didn't come to mind. I was looking at the refurbished section and apple is selling a (non retina) 15' MacBook Pro 4GB memory, 500GB hard drive, i7 quad core processor.

My 13.3" macbook pro will not power up.The battery indicator light does not come on.The Mag safe charging light flickers green and red dimly.I had a cell phone connected to the USB port.

This didn't work for me, so I did a bit of searching and TONS of pages later in google, I found an answer. Here are the steps for people who also were in my situation:
1. Take off bottom case
2. Unplug battery - blurry image here: http://i.ytimg.com/vi/03cC79r5Dx4/0.jpg
3. Press and hold power button for 5 seconds
4. Plug a charger in, and it should start booting up
5. After shutting down again, reconnect the battery and close the case up
6. It works! (hopefully, if you guys had the same situation I did)

I have a early 2008 Macbook pro and just bought a new battery, but it is not holding a charge

I have a late 2008 Macbook pro and just bought a new battery, but it is not holding a charge. I read it may be the charger,
that sometimes is blank, but it does charge my computer.
Anything I can try?
I have updated to 10.9.2

Bring it back to the Apple store with your MBP and charger. If the battery is found to be defective, they should provide you with a replacement (assuming you are in the warranty period).
Ciao.

My macbook pro (late 2008) shuts down but battery is at 25-30%

My macbook pro (late 2008) shuts down but battery is at 25-30% and I don't get a low power warning box before this happens. This only happens when the power chord is not connected, and it restarts with no problems once I put the power chord in. Does this mean I need a new battery, or is it an indication of something else? Using osx 10.5.8

Mine is Unibody 15" MBP late 2008, with the exact problem as yours. It can be a sudden shut down at 25-32%, or, after upgrading to OS 10.7.2, can be hang all of sudden on battery power.
Condition on, "Replace Soon". From 4.5 - 6 hours when new, goes down to 1 - 2 hours on discrete graphics.
But after 'abusing' it for the first year in the heat of Jakarta's climate in a non AC room when doing a video editing, before moving back to a comfort AC room at home sweet home, the battery performance is still top notch comparing to other kind than Apple. Also, it caused me to replace the right fan, after a lot of hard work on that first year. Oh, and by the way, I regularly done the battery calibration, at least once or twice between 3-6 months.

Macbook Pro random shut down whilst using battery

My Macbook Pro randomly shuts down whilst using battery power even though their is plenty of charge in the battery.
Any ideas??

does it do it when plugged in?
Also it sounds that there's a power failure and causing it to shutdown, I would get it serviced asap, the battery connector might be faulty.

Why does my brand new MacBook pro have 13 cycles on the battery right out of the box?

Why does my brand new MacBook pro have 13 cycles on the battery right out of the box? Shouldn't it have 0 because it's brand new.

Yes it should have 0. I would return it, that means that the battery has already went through 13 full cycles. Perhaps they accidentally resold a returned one as new.
