mbp 2.3ghz owners - what kind of battery life are you seeing?

full discharges shorten the battery's life

As stated, yes that might be the case - but if you want a calibrated battery, then you need to tell the battery where it's at

Also I don't fully 110% discharges the battery, as I say above, I let it go down to 2-5% and then start charging it again.

I have always had great battery life in all my portable devices - do you think I'm lucky or am I doing something right with my batteries - up to you to decide

Im on (6:01) With 99% charge, mine wont go to 100% no matter how many times i try to calibrate the battery.I have never seen anything above 6, so i don't know how people are getting 6.5 to 8. thats just not fair!!

Read the FAQ I posted to learn why it's normal if your battery doesn't charge to 100%. It's nothing to worry about. Also, the life you get from a charge is dependent on a great number of factors, including screen brightness, WiFi, Bluetooth, apps/widgets/processes running, etc.

I have nothing running besides the regular dashboard, word processor and this safari window. No backlit keys and screen at 50%. I got (87%@5:45)

To see all you have running, launch Activity Monitor and change the "My Processes at the top to "All Processes".

I can usually go 4-5 hours usually on a full charge—dedicate GPU on at all times, WiFi on, screen at 50% brightness.

If I want more battery life, I can turn the brightness to about 20%, use the integrated GPU, and can go about 5-6 hours with no issues.

whelp, on the 2nd full charge, it's been going all day.


me = spaz.


or maybe it just needed to calibrate itself

do you reckon it could have been the graphics card? i found, before i set it to integrated, that the discrete graphics card was the bigger energy consumer and the littlest thing would enable it, like chrome or youtube.

3-4 hours running SAS, 4-5 for browsing. Take that sucker back. That battery could power New York City for 45 minutes.

Checkout the anandtech benchmarks of the battery life:

notice: browsing sites with heavy flash content with discreet graphics only yielded less than 3 hours

Finally check out their full battery test:

Their multitasking benchmark, with downloading, flash browsing and quicktime x - the macbook pro only lasted a meager 144 minutes.
