i have a 17" macbook pro, purchased december 2011 — so it’s 18-months old.

OS X version 10.8.4

recently i noticed the battery doesn’t hold its charge very long. this may have been occurring for a while, but only recently did i pay close attention and actually timed it. the first thing i did is closed all my applications from adobe CS6, and with only internet browsers running (safari and chrome) the most time i get is 2 hours.

i talked with my technician and i went by his shop so he could check the battery. well, the battery is completely fine. of course, with the extra drainage, it may have aged its life cycle, but it still has more than 50% life left in it.

my technician suggested i keep an eye on the activity monitor when the fan gets going hard (which it always does) and the only thing showing high CPU usage is google chrome, which shows variable percentages from 20% to 65%, and then a whole bunch of little % — not sure if each refers to a page opened.

my technician said "get rid of chrome" but i really like using it (i used to run mostly safari until their last update but they changed some preferences and i hate what they took out so i switched to chrome).

so before i do so, is there anything else i should try?

  • Do you have any plugins installed in Chrome?

To save some juice disable the Adobe Flash player, and only use it for stuff you actually want to see. From now on it will ask you to confirm and will not play all the garbage automatically.

enter image description here

In case you want to do this: Chrome > Settings > Privacy > Content Settings, scroll down and click on the Plug ins Click to Play.


A huge battery drain is Flash (as Buscar mentioned), and although disabling it is one solution, it impedes too much functionality of the web. I would recommend Click to Flash, a free Safari extension. It disables flash, but can resume it on click (just like in Buscar's answer). However, it can also replace most online flash video players with a quicktime plug in, that uses many times less CPU. It's great for YouTube, which runs video's in an appallingly terrible player that easily uses over 1/4 of a dual core machine.

  • thanks alex. i haven’t been using chrome since i posted my question and my battery now holds a normal 4-hour charge. safari is not a problem at all, but i admit i miss chrome (which of course i can use when i’m plugged into an outlet). i will check to see if there is a similar "click to flash" extension for chrome.

    There is one, but it lacks the vital feature of replacing YouTube's flash player (Likely one of the more common flash apps that you run) for a quicktime one. What do you miss about chrome? Perhaps I can help you tweak Safari to cover the functionality you miss.

Make sure you don't have any legacy Adobe software installed. In particular the CS3 suite does NOT play nice with newer macbooks / OSX software.

I had this exact problem and had to use Adobe's CS3 uninstaller to get rid of Adobe Cue CS3 before my machine went back to normal.
