LG G4 :: Access Lock And Resetting App Permissions

We've discussed before that Keep Awake and Location are the primary permissions to block with Access Lock. There are quite a few apps that have those permissions active that simply do not need them. Why does ES File Explorer need to know my Location for what it does?As a group we've worked through a lot of the whittling down for battery saving and smooth use of the G4 over the past few months. I'm now circling back to some things to see if I can't tighten things up even more.

So, what are some of the other permsissions we should perhaps disable by default (unless they are very obviously needed)? What does the WiFi Change (or Bluetooth Change) permission do? Or, more to the point, what potentially happens if I disable that permission?I figure there aren't a lot of things beyond Keep Awake and Location that are big battery eaters, but what say ye?
