15" MacBook Pro Battery Tests: "Eight, freakin, hours"

Yes, Apple introduced prismatic (rectangular) batteries in the first PowerBook G4 17".
This is not news....
Wow...I just love how far we have come...seeing my 2.2GHz at the bottom makes me feel left out.
Ahem.
Your 2.2 is sitting pretty on top of my 2.0 core duo MBP.
13" MacBook Pro
I bought the new 13" MacBook Pro on Thursday. Stats: 2.53GHz, 4GB RAM, 200GB 7200 RPM (switched from old MacBook, which was an upgrade from the original 60GB).
I bought the base config of high end 13" model, then switch my 7200 RPM drive in. I can't believe they even still sell 5400 RPM drive with their Pro line.
This is a really beautiful machine, I love it.
As for a battery: when I first turned it on to play with it before switching hard drives it read 6+ hours of battery. Since then I get an average of 4 hours of battery under my normal web usage. I'm very disappointed by that. The only reason for this I can see is I keep the screen brightness up all the way up and I switched the default hard drive for a faster, perhaps less efficient drive. System Profiler tell me my drive is "Hitachi HTS722020K9SA00" incase anyone wants to know. I believe I bought is about 1-2 years ago.
I can run bench mark tests, what's the current best app for this?

I've tried and failed -you cannot get more than 3hrs. Apple lies when they say 5 hr - they have invented a good way to get away with it
Based on some of the responses if AnandTech is saying 8hrs it means with the new MBPs instead of 3 hrs you will get may be 4hrs or 5 if you are lucky.
ic. Well, I do know you discount half off any advertised battery life.
But I just thought AnandTech actually did real-life testings and the charts reflected that.
@Schtumple
Are you saying cocoabattery would indicate a different battery life?
This massive increase in battery life is clearly worth not being able to change it. It's like having 2 batteries already. Also, the way these things are designed, you'll probably change your computer before needing to take Apple up on their offer to change the battery for you.
What other 15" at this size/weight at the same pricepoint has this kind of battery life? Most cheap 15" machines have 3 hours of battery life, maybe 4 hours.

It will tell your battery health as a percentage, which might explain poor performance.
It is not that likely. You should try dimming at least a little the screen display. That is going to be one of the largest uses of speed.
The other is going to be flash. For ads and on screen video. The two of those things will drain an amazing amount of battery life, and it can happen on screens that you don't even see. There are all sorts of flash and ajax rich sites that use all sorts of battery life that are popunder sites so you aren't even really aware that this is happening.
Flash is getting some love in the hardware acceleration arena, especially on Nvidia stuff. So hopefully that will reduce background flash stuff. The other recommendation is keep your windows closed, to increase battery life.
Which is valid. The next question would be how many have 3 batteries. Because 2 batteries are going to largely be solved by the current better batteries. And then would you be better with an external power system that should give you DRAMATIC amounts of extra power, and is easier to manage than an extra battery.
So most of these peoples problems are actually acutely solved by the new solution, most people will simply have a better experience, and a small crowd may get forced into a better solution.
WIN-WIN-WIN.
Surfing Porn? Or other video. Seriously, flash for ads, or in backgrounds or in video, HAMMER the processor, more than anything most anybody does.
My old g4 easily got 5 hours when it was new. That was 8 years ago. I'm not that impressed. My buddies G3 could take 2 batteries and go 10 hours. So the bug deal is?
As much as I am stunned from the performance results of the battery, I am also surprised at how much a hit it takes with flash. As soon as I get the new MBP 15", I'm going to install click to flash. I can see why apple is so resistent to flash on the iPhone.
new laptop battery replacement
Because the hardest part of changing a battery in an iPod/iPhone has been taking the case apart Apple is making that part easy with the last gen of Intel MacBook Pros. They have 10-12 screws to remove to change memory, hard drive, optical drive &/or non-user-replacable battery. The problem will more be whether a 3rd party will produce a suitable battery for replacement. With the iPod/iPhone history we know that Apple will not make batteries available.
Has anybody had the back off of their 13", 15" or 17" Mac laptop with the uncased battery. How hard does changing the battery look? Does Apple have a paper or other type of seal on the battery? As Apple claims not to waste space with this new battery, I would not think that thinks will be buried under some second cover.

IS THIS TRUE??
This is a big deal for performance users as many MLC SSDs on the market can easily eclipse the 150MB* maximum that SATA I provides. The Intel X25M is far faster than SATAI, and even the outstanding 120GB OCZ Vertex ($325) can easily sustain 200-225MB/sec reads, and both SSDs and traditional harddrives can have short-lived, incredibly high burst speeds because they have ~16-128MB of DRAM cache.
What is the history of this issue? Have any recent Macbooks or Macbook Pros not used SATA II? Did Apple actually DOWNGRADE the 15" MB Pro to SATA I from SATA II?
Either way, that is absolutely pathetic for a $2000 "Pro" laptop to use SATA I and not be able to take full advantage of an SSD drive.
----------
*SATA I's signaling rate is 1.5Gbps, but it has 20% overhead from 8b/10b error correction, equaling 150MB/sec in max transfer rate.
The old could make 5 years
But my battery in my 17" PowerBook is nearly 5 years old now & still does a good job of holding its charge.

I can confirm the battery is amazing easily get 6-8 hours (closer to 8) each time I have used it unplugged. Its a really nice luxury to have available and makes the MK2 Unibodies all the more desirable. Not to mention the overall build quality is superior....

It's definitely true. Whether it was intentional or not, or whether it's even fixable is up for debate, but all new MBPs so far (except for the 17") have a 1.5 Gbit/s SATA connection. We've submitted it to MacRumors and all other major tech sites but no one wants to run the story.
Can we see more battery life in the Macbook Air line too, please? I love my air but the battery life is no where near that long. Oh well.
Thanks for the link, that sounds like a much better option than springing for a 2nd battery. Of course, I love how they don't include the cable that actually connects to the MB/MBP - so add $20 to whatever price it is.
That said, I'll be grabbing one of these.
