Is there something wrong with my 13" late 2013 MBPr battery?

Great news.

Turned off screensaver and my battery life is a lot better!

Try it it might help FWIW.

i have gotten at most 12 hours out of my 13" late 2013 rmbp. That was mainly surfing the web occasionally and writing papers on pages. Nothing else really happening. So yeah it's possible and it depends on what you're doing.

The 9hrs is not static, and is akin to fuel mileage numbers on cars.

So I guess 9 hours is a lie because if you use it it's 8 hours.

Its called marketing and the 9 hours is based on a some very strict (and unrealistic) conditions.
