Hi,

I've been having concerns about my battery life for a couple of days now. On a RMBP that's supposed to handle 9 hours of battery life, I was only getting about 3 or 4 hours. I had to charge my macbook as if it was my iphone (you can imagine)... Today I open up my macbook (left it at 96% the last time I used it) and it had 75% left of battery. I do some web browsing and leave it open for like 10 minutes. When I come back and wake it up from sleep, I only have 12% of battery left! THAT IS CRAZY!

Now I'm really skeptical about what's going on. Please if someone has encountered the same problem give me a solution! Is it Mavericks or what?

First the 9 hours is while only basic web browsing without Flash installed.

For you, could we see what's using the most CPU power in activity monitor? A screenshot of the battery pane in activity monitor might help too.

Are you browsing the web using Google Chrome? Because Chrome is a power vampire.Chrome is not optimised whatsoever and drinks from your battery like there is no tomorrow!

If you are using Chrome just try to use Safari instead for a while and check if this improves things!

I can never understand why so many people prefer to use Chrome over Safari.

9 hrs on minimal brightness, but it does seem to drain faster than usual. Run the coconut battery and see what's the lifespan on it. I still get roughly 4-5 hours on my 2011 retina 15"

Typo, good catch. Yes, the 2012 first release rMBP with the excellent ghosting on LG screens. :(
Apple did replace it with a flawless tint-yellow-free screen.

Curious, is it worse than Firefox in that regard? I actually prefer Firefox as my favored browser but use Safari when on battery because Safari is definitely better on battery use. But even on my new rMBP the battery still lasts a decent amount of time with Firefox. My old laptop, a 2010 MBP, lasted about 3-4 hours with Firefox.

Chrome's worse than Firefox in power consumption (I also use Firefox myself).

Dang, that's pretty sad... I always considered Firefox a power hog.
While it could be better, I've always thought people were a little bit too hard on Chrome and Firefox's optimization. Being a first party app and being the app Apple uses to get battery life statistics, Safari is obviously going to be able to get a bit more love in the optimization department than the others.
