Hi, I upgraded to Mavericks the day it came out and I've started seeing this problem since yesterday. I am getting about 4 hours of battery life where I used to get 7-8 doing the same work in Mavericks. Mavericks showed that the "Apps Using Significant Energy" had only "Spotlight" listed in it. I checked but there was no indexing going on as the indexing was already done right after the upgrade. I then checked the Activity Monitor and here's what I saw: Is anyone having the same issue or is it just me?
