Q: Battery draining very fast (low number of cicles)

Hi all

I bought a second handed MacBook pro 15" mid 2010 - the battery was renewed just before my purchase.
Battery type is TOP A1321, it only has 221 cycles and it has the OS X Battery status "Good".

More info about the battery is here: http://oi66.tinypic.com/2lo3dyb.jpg(using the coconutBattery tool)
I am working in the IT industry so I always charged my battery the way it should be (always pulling out charger when fully charged, etc etc..)

I've checked my Activity and there are no processes with extreme high CPU % usage..
I am using OSX Yosemite (10.10.5) - could that cause the problem? Should I try to downgrade?

Stil, my battery is draining fast, very fast - when fully charged I think my battery only lasts for bout 45 min - 1 hour.
For a laptop this is far from ideal so I would like to fix it..

Thanks for advices!

MacBook Pro, OS X Yosemite (10.10.5)

    Hello nic940,

    Thanks for using Apple Support Communities.

     

    I understand that the battery runtime on your Mac is lower than expected.  To help troubleshoot and resolve this issue I suggest that you follow through the steps outlined below:

     

    My battery runtime is low

    1. Identify what the battery life should be for the product you're using.

       

      The Tech Specs site provides Apple's battery life expectations for battery usage. The specifics for wireless web usage and standby time are included in the Tech Specs article for each product.

    2. Learn how to minimize common causes of battery drain:

       
         
      • Optimize your battery life using the Optimizing Battery Life section earlier in this article.
      •  
      • Learn how apps can affect Mac battery performance. Check Activity Monitor for any malfunctioning software processes, especially after installing software updates or a new operating system. Installing updates is important to ensure optimal performance for all applications.
      •  
      • If you're still having battery runtime issues after optimizing your computer's performance and checking for malfunctioning software processes, test in Safe Mode. Safe Mode limits the active items on the system and allows testing in a more minimal environment. If the battery life is better in Safe Mode, you may need to do further software isolation for the items disabled by Safe Mode to determine what the power draw is while not operating in Safe Mode.
