Help!! Inaccurate Reading of Battery

hello, 🙂

I recently bought a brand new macbook pro 13" retina early 2015 and this is my first macbook so i don't know my way around it yet. Today i noticed that the reading of remaining battery power is fluctuating i.e. at 86%, the battery remaining shows 12:02 and then at 80% battery, the battery remaining is 12:12. The charging is OK(i'm not really sure how long it should take but it's charges up pretty quickly) and i'm getting about 7 hours of usage. So, i was wondering if i can fix this myself or need to go to an I.T to get it fix.

Thanks in advance 🙂

MacBook Pro with Retina display, OS X Yosemite (10.10.2)

A new Mac comes with 90 days of free tech support from AppleCare.

The estimated battery life reading is based on current use when you look. If your computer is sitting doing nothing and you look you’ll see a higher number then if your computer is applying filters on a set of photos in Photoshop and you look. For example, at the moment I’m just typing here and saw 11:18 remaining. Now I've got a movie playing in a window and my time has dropped to 10:12 and after quitting the movie it rebounded to 10:51 and will probably go up again as I continue to watch (which I won’t). And yes, I too get about 7 to 8 hours of battery in regular use which typically involves browsing, email, word processing, and playing music.
