Same problem here. Got maybe 3h out of it, with moderate surfing and a little bit of excel work. Also, when I put it to sleep last night, it didn't wake up this morning, because the battery was completely drained. I now have an appointment at the apple store, hopefully they can figure out what is wrong.

Please keep this thread updated with your solutions from the Apple Store.
My Retina was purchased 6/20/2012 from a local Apple Store. So far, I have not experienced any of the issues in this forum (display, USB3.0, battery, heat). All Lion updates have been applied.

Will do. I also have all updates, and no issues with the display or the usb 3.0 (though i did not test that extensively, just seemed to be fine when i used it once). My appointment is on Sunday.

Well from what I've read and seen out side it was something between 5:30 to 7 hrs. Something like this one "in light use, with the backlight at 50% (it can be pretty bright, so in many cases you won't even need to use that much), you can expect to exceed Apple's 7-hour running time. We scored 7 hours, 39 minutes of use in our battery tests - which are relatively light and, it's worth noting, do not engage the discrete GPU."
But in reality without backlight and 70% brightness plus WiFi usage it was around 5:40 hrs in baseline 2.3 one.

Kind of off-topic, but since you mentioned it... have you been able to use an external USB 3 drive and get USB 3 speeds? I'm seeing posts from users who either can't even connect to an USB 3 external or are getting USB 2 speeds when connecting?
Please reply so that I can update my own 'knowledge base'.

Sorry I answer but he did post here before as I was following the USB 3 topics:
hope it helped

Hunh! And it's a WD, which many Mac users have had problems with! Well good for him... glad that the USB 3 ports are working for some (sniffing around here, you'd think they weren't working for anyone).
Thanks for the link.

One thing to remember, if a USB 2.0 device is plugged in first; then that makes the daisy chain of USB ports to the hub, 2.0.
So for example, if i plug a USB thumb or external drive (2.0) into one of the ports and then a USB external drive (3.0) into the other port, ALL of those devices will perform at 2.0 speeds. We also need to be sure the Software Updates have been applied. Especially the MacBook Pro (Mid 2012 Software Update 1.0 as it contains USB 3 device support.

I got my battery fixed now, and I didn't even had to go to the Apple store. A day after my call a very friendly technician called me back, asked for a couple of information (battery cycles and so on), and in the process it turned out that, for some reason, the dock application was running and took out about 90% (?, but that was what it said in the activity monitor) of the processor power. No wonder that drained the battery.
However, with some guided instructins over the phone and some lines in a console (i forget the name of that), the process was shut down, and even though the dock immediately reapeared, it now does not use that much processor power anymore, resulting in almost the advertised battery life.
I don't want to sound like a fanboy, but I have to say I am very pleased with the support. Thank you!

I bought my 2.6 MacBook Pro on Saturday afternoon (past).
I let it completely drain over night then charged Sunday afternoon. Upon a complete charge it woke up with 2.38 on the battery indicator.
I let it drain again yesterday and left it to charge overnight to wake up to 1:56 on the battery indicator.
I have literally just opened the lid, the brightness indicator is set at 4 notches (less than a quarter of full), bluetooth is off and only app I have open is Safari.
Something is far wrong here.
I called the Apple Store where I purchased it but they can not even swop it out as they do not know when they will receive a shipment.
Not a happy bunny.

DO NOT DRAIN THE BATTERY. It doesn't need any calibration. Plug it up and let it drain to about 70% and then charge it back up. Draining the battery will harm your battery health (it's not too late to keep it healthy, thank goodness).
You can check your battery health by going under the Apple menu to "About This Mac," selecting "More Info" and then "System Report." Look under Hardware>Battery. The report should read "Condition Normal."
For faster access to this information, download "Battery Health" from the App Store.

You're in excellent shape - your battery health is normal, as it should be, and you've only been through 6 cycles (you're good for around 1,000).
Just don't let the battery completely discharge again.
