RMBP Battery life support

[iLife87]

My RMBP battery life only seems to be 3hrs. I have every energy saving thing checked. I'm not sure if I'm doing something wrong or not. Could you guys please give me advice. I just got the mac yesterday, today is the first day I have used it off the charger and it's battery life has been horrible.

ps this is not my first mac.

My RMBP battery life only seems to be 3hrs.

I am a bit disappointed by my 3:30 battery life. Certainly better than my old Dell laptop, but nowhere near 7 hr estimate.

I do realize 7 hrs is an optimal number, but 50% less (real world) seems like a wide gap. My last charge cycle I tried a few things:

1. Brightness 50%
2. No VM tasks
3. No video
4. Very light duty browsing, emails and such

Battery Logger app reports:

Start: 100%
End: 2%
Duration: 3:35:55
Sleep: 63:41:30
Off: 00:01:33

Maybe my Mac was not really SLEEPING for the 64 hours I was away from home... ?
