    Hello, in the past I set the brightness of my MBP 2010 17" to about 3 steps down. Recently, even I turned the brightness of my MBP to the max, I often feel that it is a bit dim. Does the screen brightness drop over time?

    All MacBook Pros since the 2008 unibody redesign use LED backlights. These backlights should not lose any brightness over time. My 2009 15" MBP seems just as bright as it's ever been too. So this might be a problem with your specific sample. Not much you can do about it besides replacing the screen (assuming you already tried a PRAM reset, though I'm not confident that it would help).

    No, since it's an LED backlight. Apple's displays are getting brighter with each release so if you've used any newer displays perhaps it's altered your perception.

    Environmental light has a huge impact on how bright a display seems. During the day I use max brightness and at night usually 70%.

    That's not true. LED backlight do slowly lose brightness over time.

    I see the same thing with my 2011 MBP but it doesn't bother me that much unless it's very sunny.

    I have an early 2011 MBP, and its screen is still in perfect condition.

    All LED panels will drift overtime. That's why they sell monitor calibrators.
    3 steps down isn't a very accurate way to control the brightness.

    Could it be the difference between running on battery vs AC? I know my Dell does that.

    Nope. A display will change overtime. The only way to know it's the same is to measure it with a device called a colorimeter.
    You can't even trust your eyes.

    Agree. I use a colorimeter to calibrate the brightness and colors every month or two I find they do drift and there seems to be no predictable pattern. I am pretty sure sometimes it takes out part of the adjustment it made during the last calibration.

    What is the screen size? Wonder if the 17" 2010 batch has this issue.

    All LCD panels from all manufacturers have that issue! Nothing to do with certain MacBooks.

    My MBP is 7 years old and used almost everyday, the brightness is still perfect (and way better then my 2014 MBA).

    Your 2014 MBA is a different panel technology to your MBP isn't it?

    Yes, the 2011 MBP is way better than the 2014 MBA, being 3 years older tech.
