Q: Mid-2015 MacBook Pro 15 Has Horrible Battery Life
I have a mid-2015 15 Macbook Pro that is the base model, 2.2 Ghz and 256 with no graphics other than the Iris Pro. I've only had it for about 3 months and I take it off power once a weekish and use it around the house. The whole reason I decided to go Apple was because I wanted the battery life that windows machines can't offer with this kind of power.
I must have gotten a dud or something because my battery life is bad. I run display 50% and backlight OFF and don't keep anything open. My Dock has nothing open except for mail to notify me and my browser if I'm using it (98% of the time). Battery life is maximum of 4-5 hours of doing this constantly, the only time I've achieved more was on a road trip where I turned back light and display off and was only using iTunes to play music through my headphones via bluetooth, that time it was projecting 20+ hours. Just getting on here for the last few minutes has gone from 38% to 19% over 31 minutes of time on battery. I know a decent amount about computers and I'm a massive energy saver unless I'm plugged in, low brightness, no backlight, no programs open that I'm not using etc yet I get ridiculous battery life.
What should I do? Any suggestions? I read somewhere about powering down and then when you power back up hold Option + Command + R to reset some thing inside the machine.
Is my battery life normal for what I've described? It's not like I'm that idiot that knows nothing about computers and leaves open pages, mail, messages, itunes, skype, and browser just because I can. I leave nothing open (Hence no programs on the dock have the "dot" under them), I clear everything that is unnecessary VIA the Activity Monitor, things such as Creative Cloud. I'm just stumped. I must have gotten a dud. Please help and advise me on what I should do/try.
Currently running OS X El Capitan 10.11.3, but this is not just because of El Capitan, this has been like this since Yosemite when I first bought it.
Thanks
MacBook Pro with Retina display, OS X El Capitan (10.11.3), null

Does it do anything different with, say, Safari? And have you watched Activity Monitor while you're using Firefox?
