Q: Macbook Pro: poor battery life and running very hot

Hi,

I have a mid-2014 15" Macbook Pro retina screen which I bought almost exactly 12 months ago now.

A couple of months ago it started to get very hot during just moderate use (maybe 10 tabs open in safari and spotify playing also), and the battery life is significantly lower than it was (I currently have 3 tabs open in safari and am playing music from spotify; my battery percent is 89% left which it says will only give me 2:15 remaining time). Here is my current battery status:

Is there anything I can do to stop this problem? The problem arose fairly suddenly, and before it occurred I would get up to 9 or 10 hours with moderate use.

Thanks in advance for any help!
