    I'm not sure if this is a known issue or not, but I just received a new rMBP and was shocked to see the battery drain - almost an hour and a half to 2 hours while doing NOTHING...just leaving a screensaver on. Has anyone else noticed this? Even watching movies or doing PS work preserves more energy. If I can't use a screensaver how am I supposed to avoid this image retention??

    Which screensaver are you using? The flashy 3d ones use up a lot of CPU and GPU power. Even something as simple as "flurry" uses up CPU power. If you want to use a screensaver and not have it impact the battery, the best screensaver to use is 'computer name'.

    Screensavers aren't required for LCD screens - They won't burn in.

    Thanks for the advice Cube...that seemed to actually just about rid the problem completely....I forget which saver I was using but it was def one of the more intense ones. That ALONE probably saved me 3 hours per charge - I think it may be worth noting for people who might not be aware. I never realized just how much those screensavers burn.

    Without getting into the whole screen issue again...what do you do about the IR? Do you have a retina? Did you happen to land one of the Samsungs? I know it's only temporary...but it's extremely difficult to just leave a browser open or a static image up on the screen when I've been experiencing some image retention. Is anyone else in my boat? What do you guys do? It's prob not a huge deal, and may not be that detrimental in the long run, but there's this constant nagging knowing it's gonna stick on the screen. Maybe I'm just completely OCD and need a good Dr instead of a new screen.

    I personally don't own a rMBP, however a friend of mine does, and he leaves the screen displaying static things (like torrent clients) for long periods of time (at last several hours) and he hasn't noticed anything. If you seem to be having problems though why not just shut your MacBook's lid when you're not using it, rather than display a screensaver?

    Screen-savers are so 80s. Really! They used screen-savers on CRT because they couldn't figured out how to just turn off the beam. Then eventually did. With LCD, the concern is now power saving, not necessarily that it hurts the display. I personally would just set the LCD timeout value.

    Yes - I was under the understanding that LCD displays don't 'burn in' like CRTs did.

    I don't even have an answer for you....I just seem to be conditioned to. I've always used hot corners, and whenever I'm not typing, I guess it seems quicker to just hot corner the screensaver than to close it. Several HOURS!....I feel like I'd be seeing double after that long - I really don't know how intense the issue is though. You know, I don't know if I would have noticed it either if I hadn't set a desktop that was more solid (intentionally...to check for it) but with a more solid desktop set it's now painfully obvious. I'm curious which screen he has but I'm not going to ask...I'm actually sick of these IR/burn-in in threads.

    I've disabled screen savers on all the computers I've owned for 10 years now. I just have the display turn off at whatever time the screen saver would have turned on instead.

    Is there any reason why you can't just shut your laptop lid?
