13" MBP 6 + hours today. Phenomenal battery life so far on this machine. I'm starting to learn you can't really go off of what the battery indicator says at the top, it seems to fluctuate based on what tasks your performing. Thus I just time it from a clock from unplugging power adapter to computer crashing.

Tasks during this time:

Safari
Adium
iTunes
Text Edit
Pages
Mail

Half screen brightness
 
When I do video editing with iMovie, I get around 2-3 hours on a 13" MacBook Pro. Very good battery from my previous laptops.
 
i have 8:22 on my 13"uMBP!?

I think 4h or something with my 15" MBP (june09).

But sometimes I have brightness at full and powerful apps running like After Effects and Photoshop. And copying files from HDD also needs battery.

But if I want, I can make 5 to 6 hours out of my MBP I guess.
 
Not a lot of cycles but I have gotten over 8 hours several times. Mostly surfing with Safari and a bit of word-processing. Nothing with intensive power requirements. Very good none the less. I wonder how it will do with Movies?
 
July '09 17" MBP(7200 RPM drive). Between 7:45 and 8:20 with firefox, adium, word, and some itunes (screen at 5 notches, CPU usage under 5%). Have gotten up to 9:30-10:00 when leaving the computer idle(not sleep though). Loving it :D

Well what about if you were actually running some apps?


I get about 7-8Hours on my 17" early 09 2.66
Firefox, iTunes, iPhoto (connected to an external display, Better battery Life/9400)


I seem to get longer battery when not using Firefox, but Safari, since FF tends toe eat alot of memory (as i use multiple tabs, etc) just tends to waste battery from my experience.
 
After 15 cycles i now get less than 2 hours, with half brightness and just some light wireless safari use.

I seemed good when I first bought it but after I installed Parallels 4 and then XP it's almost faulty.

i rang customer care and they said I can have it replaced

a pity as everything else on my mbp 13 2.56 Ghz is savage
 
On my 15" Late 2008 MBP I get about 4-5 hours running Safari, Mail, iTunes, Adium, etc at about 75% brightness
 
For the 15" and 17" models you should note whether you are using the 9400M or the more-power-hungry 9600M GT graphics mode.

I suspect that the 13" has the shortest battery runtime given that it has the smallest battery. Similarly, I'd guess that the low-end, 15" model that omits the 9600M would get the best battery life or at least that it would be very close to that offered by the 17".

Also good times up there for the 13" unibody Macbook. :D

Mine gets about 5 1/2 hours under normal usage, just browsing online, no videos, etc. Watching a DVD I can still get about 3 1/2 hours.
Not quite as good as the pros but worth mentioning. Also far far better than any other laptop I've used in my life.
 
My time was posted using the 9400M. I never use the 9600M on OS X because I don' t do gaming or anything on OS X. The only time the 9600M gets used is in Windows (for gaming), which doesnt have the option to use the 9400M
 
i get about 6 hours of battery time, question do you guys ALWAYS leave your mbp plugged in? i keep reading mix opinions about it. TIA
 
About 30 minutes on a 15" MBP (2007). And that's on my 3rd battery. The health drops rapidly despite conditioning my battery about once a month. Right not, my 6 month old battery is showing a stellar 29% health with only about 30 cycles. And when I talk to Apple about this (having gotten Applecare so I know they'll take care of me) they tell me to buy yet another battery. :mad:

Surely, the fact that it's happened with 3 different batteries, it couldn't be the computer.

If it is a full battery and I turn my mac off or sleep, I'll unplug it. But, if I am USING it... I keep the power cord in.
 
Before calibrating my MBP 17" (Mid 2009), it would say about 8 hours (Medium brightness, WiFi, web browsing, iTunes and Adium).

After calibration it's about 7:30 of real-world use.

Modern Li-Ion batteries do not require conditioning. In fact, conditioning Li-Ion batteries can actually damage them and cause them to lose capacity. This could explain why you've had three batteries. :)
