I have a 2016 15" MBP with Touchbar and have issues with battery life. Just today I started working around 10 AM with a battery charged from empty last night and already before 2 PM it is saying battery is low. This including about 40 minutes for lunch when I wasn't using it. I don't have anything heavy running (mostly Chrome, Slack, Sourcetree and a code editor), the battery menu doesn't say anything is using significant power. Running OSX 10.12.4. Is my battery faulty or something?
