Poor Battery Performance

We’re starting to get the new 2018 MacBook Pros on campus and we’re seeing very poor battery performance. A fully charged laptop goes to a dead battery in 2 - 4 hours. A MacBook Pro out-of-the-box seems fine, so we’re investigating the software we add to the Macs.

We’re starting to suspect the BigFix agent as the load on the laptop decreases (sometimes significantly) when we remove the agent. (We’re running BigFix 9.5.9.)

Has anyone else seen poor battery performance on the new MacBook Pros?
