Ouch. But I can hardly see why that could reduce battery life so much. The new power-saving features in Mavericks shouldn't, in theory, lower the battery life.

The OS should act like it did under SL unless lots of RAM is needed (I'm at 50%). I'll let the computer go through a couple of power cycles, maybe that'll fix it.
- mitchty 13y agoThe reason is in chrome the background tabs don't get frozen and stop executing etc... Safari has had a huge makeover to improve the amount of energy use for things like background tabs/etc.... Or even not running when occluded by another window. Small things like that add up overall. I think this is the way forward for improving the efficiency of our software in general. I'm glad someone is bringing power use to light alongside cpu/memory/disk/network. As for the os level stuff, have you tested the actual time under use or just looked at the estimates?
- chm 13y agoI got 4:56 minutes out of my battery today. I switched from FF to Safari when I wrote the previous comment. It did make a difference.
- mitchty 13y agoI'm noticing the same as well with my retina actually. The power drain differences are significant enough for me to swap back to safari. I was getting ~7 hoursish (hard to tell I tend to compile/browse/etc) before and now it looks more like 5. Which is disappointing to be honest. Though using non "best for retina" seems to kick in the discreet gpu more often now.
