Hello everyone, Purchased a Macbook Pro 2011 from a reputable computer store in my area, came with a decent warranty (3 mths) w/ the option to extend for another 2 years for 130$. The issue that has arised is that the battery life is really not what I have been told is expected from these notebooks. I usually get a maximum of 4 hours maybe 4.5 through light usage (Pages + iTunes at half screen brightness). I went back a few times to complain and each time they replaced the battery life with what they claimed to be a "new" one. The battery life remains the same approximately each time and the service battery indicator always comes on after a few weeks. I decided to download coconut battery and it told me that the "new" battery that was straight from Apple holds 75% of it's original capacity. The store declined to comment on this statistic when I told them about it but told me that I would have to leave my laptop there for a day or two so that they could run there own tests. I am not entirely sure how to proceed from here as the battery has already been replaced numerous times and I made it clear that this around I want a battery that is brand new with 100% health. Any advice? The battery life has not differed much across OSX 10.9 or 10.10. Usually always 4-4.5 hrs with moderate usage and even less once i get a few light apps running with the browser (moderate usage to me). I must also mention that I have done SMC resets as well as PRAM resets as per instructions on apple forums multiple times. Specs Macbook Pro 2011 13" w/ Dual Core i7 (2.7 ghz) and 4GB RAM and 500GB HDD Any suggestions would be appreciated. Many thanks.
