NEXUS 4 after kitkat update

Hey guys,i'd like to ask y'all here who have a nexus 4.What's your on screen time after updating to kitkat?
The n4 wasn't never a "battery beast" but after updating to 4.4.2 in can get maximum 2,2 hour of on screen time while using the 3g....That's more or less 30-40 minutes less than before .I'm i the only one who's having these issues?
