MacBook Pro - late 2013 Battery Life declining

I have noticed in the last couple of weeks that my Battery life is not what it used to be. Until recently, I would be able to charge overnight, and then take to work with me and have on most of the day without being plugged into the mains and still have 30 or 40% battery left when I get home. Now it seems to decrease quite rapidly and even more so once it gets past having 40% left.


I also noticed last night that when using Chromecast to stream to my TV, it really eats up the battery.


I have a 15" MacBook Pro, SSd pro-retina - I have not yet upgraded from Mavericks to Yosemite as I read so many people having issues with Yosemite.

MacBook Pro with Retina display, OS X Mavericks (10.9.5)

Reset SMC. http://support.apple.com/kb/HT3964


Choose the method for: "Resetting SMC on portables with a battery you should not remove on your own".

1. Check the cycle count of the battery against the rated life for your model. The battery may be due for replacement. If the power adapter is connected almost all the time, the battery may need replacing even though the cycle count is not too high.

2. Follow these instructions, or thesefor OS X 10.8 or earlier.

3. In the Energy Saver preference pane, uncheck the box marked

Enable Power Nap while on battery power

if it's shown (it may not be.)

4. You can also try resetting the SMC.

5. Make sure your system is up to date in Software Update.

6. Make a "Genius" appointment at an Apple Store, or go to another authorized service center.

Hello David,

Often excessive battery usage is due to unexpected CPU usage. I wrote a little diagnostic program to help show what might be causing these problems. Download EtreCheck from http://www.etresoft.com/etrecheck, run it, and paste the results here. EtreCheck is perfectly safe to run, does not ask for your password to install, and is signed with my Apple Developer ID.


Disclaimer: Although EtreCheck is free, there are other links on my site that could give me some form of compensation, financial or otherwise.
