My MacBook Air is set to sleep when the lid is closed. However, I frequently (but not always) open the lid to find the battery drained completely or instead, find the computer warm as it had never slept.
How could I find out which app is preventing it from sleeping?
Thank you!
MacBook Air 13", 10.14
Open Activity Monitor in Utilities>Energy tab, sort on Preventing Sleep, any listed?
Also, EtreCheck is a simple little app to display the important details of your system configuration and allow you to copy that information to the Clipboard. It is meant to be used with Apple Support Communities to help people help you with your Mac.

Pastebin is a good place to paste the whole report...
Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck.
