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?
