Therefore, you can probably freeze some, especially the location services, without having any effect on the Play Store.
I think you are correct.
I reset my battery monitor this morning and will look after I get a few days of stats to see what else runs and takes up battery that is basically useless in a music player.
Since I posted the original screen shots of what I had frozen I added Maps, the HTC Location Service and just this morning Google Play services. I forgot about the first two until your post.
These are the three processes I have frozen since in my original screenshots:
I would like to freeze anything Google that doesn't break the Play Store and GDrive. Not everyone would care about GDrive but I like the convenience of it. If you don't use it, it could probably be frozen too.
I'm usually the cause of any battery problems now if I forget to switch off WiFi or use the screen too much while creating new playlists
.. screen timeout is a big deal if you are trying to squeeze every minute out of your battery.
