Android System eating battery since update in July

[oddstar]

A software update was pushed to my phone in July, and since then the Android system is using more than half of my battery. When I first got the phone the  Android system used around 20-23% and now it is using 49-58% of my battery. When I select the graph view I see my Mobile Network Signal is brown all the way through. I am in Lincoln, NE. My roommate has the same phone, we live in the same place and he does not have these issues. What can I do to help this?

I always strongly suggest after a major update, that you backup your info, pix and such and do a master reset.
