I have a 2017 MacBook Air running 10.13.5 I bought in March and have been having issues with the battery heavily draining while closed. While I LOVE Chrome, it was hindering my productivity in not allowing me to have a full day of battery....maybe 4-5 hours at most.
So, I ditched Chrome. That helped a lot. With the right tweaks, Safari will work.
The other part that helped was to reset the PRAM and SMC.
Testing last night...charged it to 100%, unplugged and closed the lid. Opened this morning and still at 100%. This hasn't happened before. typically I would see about a 30-40% drop in battery overnight.
Hope this works for others. I was starting to wonder if I had a bad battery in my new MBA.
