Sierra Killing battery life?

[organic bond]

In my case the culprit was Windows indexing, in fact I use it virtualized. I disabled indexing as I don't care about it at all, and the battery came back as before. Also disabled some notifications on OS X. And this is with Sierra, I have not not noticed anything different with it.

My battery has been destroyed in my Air - I think same model. From all day to about 2-3 hours. Cannot figure it out.

Try:
a SMC and a PRAM reset.
boot in safe mode and let it there for some minutes. (I did it twice).
Also if using safari check for old plugins or better disable temporarily everything and check, also in safari preferences -> security -> plugin settings.

I have also noticed that Mail has some issues now, when closed the temps are certainly lower.

Good luck...

With El Captain, my work mac (macbook pro, retina, 13", 2014) would use maybe 7% battery when asleep. Under the same circumstances, my mac's battery was totally drained (0% left) this morning, meaning that, with Sierra installed, it uses 100% of the battery when asleep!

Oh dear that not good.

I never put my mac or ANY laptop to sleep as had issue waking them up in past.
more so with windows though.
