@Franc_Iphone, it is normal that battery time reflects upon the level of load you place on the system. What matters the most is the overall battery time based on average computer usage load.
With iPad, Apple seems to be very good at providing awesome real world battery life estimates. But I wonder why they can't do the same with MBP.
Antonywi... I concur. All I ran, on a brand new Mac Pro (3 days old in the store) was Safari (no flash) and FaceTime. It's no wonder, since my "real-life" consists of VMWare, Twitter, Iphoto, Adium, Drop box, that all I get is < 3 hours. I just wonder what you have to do to get 7+ hours (playing video) as the announcement for the new Apple Mac Pro's claimed!!!!! I do get 4 1/2 hours if I run GFXcardStatus (30% more) so it's not just my machine but the O/S too!
Ipad's programs, there's few that are real work-horses so estimating is 10x easier, as it is on my DROID XOOM tablet.
I have a 17" Macbook pro. Am about to get the battery replaced for the third time in four years. It runs too hot to touch (hot enough to burn skin), loses 100% of its charge in 1 hour 45 minutes. I have been through this twice before, same problem. This power loss is just doing email, and yes Apple, I follow all of your instructions to maintain battery life.
Since owning this computer I also had to have the video card and a few other things replaced.
After a while the ease of operation does not make up for poor durability. With regrets, my next computer will not be a Mac. The competitors products are very good now.
There's no way three batteries could have been faulty. Something else is wrong with your system that is causing the battery to drain rapidly.
1. Check Activity Monitor to see what's using up all your power while the battery is draining.
2. Remove all items from
> System Preferences > Users & Groups > Login Items
3. If you're on Lion, boot into the Recovery Disk, choose 'Disk Utility' and 'Repair Disk'.
4. Do both a PRAM and SMC reset for good measure.
@Rbisha, have you tried the smcFanControl? That program helps regulate the fan speed to keep the temperature in check. For my 15" MBP, I mainly use it for development and code compilation. From time to time, it does heat up, sending the fan speed up to 5000 rpm, but so far so good.
I haven't yet decided on whether my next laptop will be a Macbook Pro or ThinkPad X1 Carbon (or even the good old T series), but I definitely have better battery life with my ThinkPad than with my MBP. And yet, working with MBP remains quite a pleasure, as long as it is plugged in to the outlet.
In principle I agree, one would think there should be something else wrong to have this many battery problems. However, when I have taken it to the Apple store with battery issues (and only Apple technicians have ever worked on it), they have assured me everything else is fine. Yes, we have checked the Activity Monitor. (I am using Snow Leopard.)
So, either there is something wrong with the computer or the systems that Apple technicians have failed to identify or tell me about, or there is something wrong with the batteries. Neither option leaves me wanting to buy another Mac.
To use an automobile analogy. If you buy a car, and have to replace the battery three times in four years, only to discover there is something wrong that the dealer's own mechanics didn't catch, would you buy that brand of car again?
I didn't think so.
I appreciate antonywu's suggestion for fan control, to look at the multiple discussion boards this seems to be a common and longstanding problem. Thanks too for the suggestion for ThinkPadX1 Carbon, I will check it out.
I've taken my cars to plenty of dealers with crap mechanics.
Apple store 'technicians' aren't necessarily always all they are cracked up to be. Did you get a store 'genius' clerk, or a real tech pro? Did you get someone (like I did at the Epson Service center with my printer) who was wanting to go on a break, but had to deal with you first?
If you've tried the steps I gave you above, run your mac in Safe Mode. Does the battery still get depleted as fast? My bet is 'No', in which case you have a 3rd party software problem. If I'm wrong, then the best suggestion I can offer you is go to a different Apple store.
I say again, the chances of three batteries in a row being faulty is so slim that it is almost 100% certain that there is something else to blame.
I had the same problem (drastically shortened battery life after upgrading to Lion.
Resetting the SMC (System Management Controller - similar to CMOS in Windoze systems) did the trick for me.
Note: Portable computers that have a battery you should not remove on your own include MacBook Pro (Early 2009) and later, all models of MacBook Air, and MacBook (Late 2009).
- Shut down the computer.
- Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
- On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
- Release all the keys and the power button at the same time.
- Press the power button to turn on the computer.
Note: The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.

Ugh... I feel like Apple is hanging a giant carrot in front of me except I can never reach...
After SMC reset, for the very first time, I saw 7 hours and 30 some minutes left after unplugging from outlet!! And then, as soon as I launched Firefox, the hours just pluments all the way to 2 hours and 27 minutes.... >_<
This ... can't be happening.. must be twilight zone!
Error seemed fixed with 10.7.4, but after recent Camera Raw Update & (in my case) Epson Printer Update the low battery life is back, my mac book pro mid 2010 seems to get hot while doing not really much.
Already tried everything here, that is just really disappointing...
Did the error reappear with anyone else?
From all I can gather, the issue has to do with some sort of bug in the 10.7.4 code for controlling automatic graphics switching. -Particularly after installing any program that makes use of the graphics switching capabilities.
In my case, resetting the SMC wasn't enough. -I also had to (re)toggle the Graphics Switching setting in the Energy Saver section of System Preferences. -The box should be un-checked, then re-checked, then system restarted.
I've been consistently getting my usual 6 - 7 hours of battery life for the past 2.5 weeks now.
I also did install GFX Card Status and hard-switched the graphics mode to internal only, and it immediately lengthened the battery life... So that's when I realized that Lion was switching to the high performance graphics processor, even when running on batteries. Note: I am not currently using gfxcardstatus... and still getting the normal battery life. -I just installed it for trouble-shooting purposes.
Again, this may not work for every one, but it's worked for me.
It seems to be a problem related to the new OSX,
I've got a new MacPro 2012 13" (Lion), and when I began to install my favourite apps, battery decreased too much, having less than 3:30 hours average battery life.
So i tried delete the most things I don't use (some email accounts, gestures, some automatic adjustments, apps with background services) and battery life get better, now i'm getting nearly 5 hours, but this might not be the solution, it only makes OS useless o little uglier I hope there will be a update soon or I'm gonna hate my mac cause i've paid too much for a "great hardware and operative system"
