    You have a 5-year old laptop - with a battery that is well past its design life.
    There's only one way for you to achieve a better battery life:

    That makes no difference, the battery is old and past its prime.

    There must be an independent place you can take it to who can change the battery for you.

    Sounds like you either need to replace the battery or look at getting a new Lap top

    I had a 2011 MBP, where Mavericks seemed to drain the battery quicker than under Lion or Mountain Lion. I upgraded to a late 2013 rMBP, and sold the 2011 MBP, so I can't comment as to how it performs under Yosemite.

    I'd suggest running the hardware diagnostics to see if there's hardware issue contributing to the constant crashing. It kinda sounds like you might have some RAM that's failing, but there also could be some software that's goofing things up.

    If nothing shows up, I'd recommend doing a clean install of Yosemite and reinstall all your app's (yeah...I know that takes a while) to see if this clears up the crashing problem.

    Please tell me that data is backed up.

    Always back up.

    SMC fan controller will make no difference to battery life. As has been said already at 5 years old your battery needs replacing. It is not difficult on those old 2009's just order a new one and look up a guide on how to replace it on you tube.

    Well a little google searching...

    This place looks ok.

    Did you run the hardware diagnostics test to see if there was something wrong with your MBP?

    He has 1500 load cycles on a battery that's rated at 1000, so this is normal.

    However, I'm going to post mine as I feel like I'm getting sub-par battery life

    Let me know what you think about this. I'm going to do a calibration today and see if that helps

    That battery is also nearly 5 years old, while battery life is influeneced by load cycles, age plays a much more important role than people think. To be honest that is fantastic for a 4 years and 8 month old battery.

    That 1000 load cycle rating is for use within 3 years and with a rating of still getting 80%.....

    You rae getting 89% on full charge after 4 years 8 months you can't ask for more than that..

    The 89% is for current charge, not capacity, the capacity is showing 81. But I do understand what you're saying about time as well as usage. I figured that was probably the case.

    I assume you are in the US

    This place looks ok for apple batteries if you need a replacement..

    Thanks for the advice but as you can see by my load cycles over the life of the machine that I don't use the battery much. I'll probably buy a new MBP within the next 2 refreshes anyway.

    What you're seeing is completely natural for several reasons.

    First of all batteries are components that simply wear out and have to be replaced every few years the same way tires, alternator belts, brakes, spark plugs, windshield wipers, motor oil, transmission fluid, various ball bearings, air and oil filters are on cars. It's simply just a law of electronics.

    Second of all is that what you're using isn't exactly very light on the battery. Youtube uses Flash very heavily and Flash is a well known batteryhog due to poor programming (you can thank your neighbors to the south for that) and a general refusal to open up the standard so that the problems can be fixed. Minecraft, or rather games in general very light on the battery and Minecraft is actually a lot worse than what you'd think when you see it. It used to be worse when Notch was still lead developer, but it still suffers a lot of wasted CPU cycles and memory stemming from being built in a language called Java (which I personally hate for a number of reasons).

    The reason why I Java is bad from a resource use perspective stems from the fact that it's supposed to be a language to make software that'll run on any hardware and any operating system. To achieve this programs are not translated into machine code like most languages, but so-called Java bytecode. Rather than being run natively on the hardware, it's instead run on something called a JVM, or Java Virtual Machine, a software machine inside of a machine, which naturally wastes a lot of CPU time and memory, eating your battery faster.
