Q: Battery life
Hi guys.
I just bought a new early 2015 MPB 13 with retina display, 2.7Ghz, 256 SSD, 8GB of ram. I bought the laptop a week ago and I'm a little worried about the battery life.
Running only Chrome with display a few marks past 50%, BT on and on WiFi of course, the estimated time with 50% of battery available is 3 hours or less, with 30% is only 1:50 or 2 hours.
I know how this works, I understand thats an estimate and it's really variable depending on CPU usage, display dimm, etc. I did check the battery health and even the details using cococabattery, everything seems ok, but still sound like low estimates for me and I don't think is software related, as soon I got the MBP I made a fresh install of 10.11 so I don't have anything, my CPU is below 10% usage when I got these low estimates.
I own a 2014 macbook air that has way better estimates and I was expecting to see something very similar to that on my new MBP, maybe I was expecting to much?
What do you think guys? What are your estimates for lets say 50% charge?
PS: I created a new thread because all I could found was from over 2 years ago.
Thank you!
MacBook Pro with Retina display, OS X El Capitan (10.11), null

Sadly there's not a direct answer, depends on what your MBP is consuming besides if you run Chrome to see videos, or just web browsing, extensions, etc.
I suggest you check with Activity Monitor (located in Apps » Utilities) and see if theres something unusual, regarding CPU, Memory, Energy (app Nap) and Network.
After that if you don't see anything abnormal you can run some diagnostics About Mac notebook batteries - Apple Support
