I tried to use the phone as I normally would. My battery would die between 11 and Midnight. I then did the same thing with GPS off for a week. My battery died between 11 and Midnight that week also. I waited about two weeks an repeated the test with the same results.

I don't use Tasker, but instead use Setting Profiles. I had much better (quicker) results with location based rules with GPS on than I did with it off. Sometimes I would be home (or at work) 30 minutes before my rule would fire to turn WiFi on without the GPS turned on. With GPS turned on, WiFi would be up and connected before I got into the house or office.

This is just FWIF,
