    Just wondering in average how many hours 2012 owners are getting with their Macbook Pro and Retina Macbook pros these days. Let me know what OS you are running and whether you are using the original battery or not. I recently replaced mine and I'm getting around 6-7 hours with MacOS Sierra.

    I'm getting 4-5 hours. 790 cycles at 80% health. This is my second battery in my 2012 retina (15") (which had about 800 cycles at about 70% health before I got it replaced under AppleCare).

    I'll probably replace the battery myself again one of these days.

    Mine was sent in for a new logic board to replace a failed dGPU (should be returning tomorrow). Before I sent it in I was at about 70% health at ~800 cycles. Got at most 2 hours on battery. Very disappointing, but was told by the rep that sent in my laptop for repair that he would request that my top case be replaced which means I get a new keyboard and battery.
