I upgraded to Mojave a couple days ago. My battery life dropped by 50%. I was getting about 7-8 hours before. This morning, I started using my computer (with brightness at about 25%, just email, Slack, Chrome) about two hours ago and I'm already down to 57%. I had a 2016 before and the battery life was terrible. When I first got the 2018, one of the biggest differences was a significantly improved battery life, so it's disappointing to see that benefit disappear. Is anyone else seeing this? Anything I can do about it?
