Hi sawalker3,
I want to help get to the bottom of what's draining your battery. I like to the get the most out of my iPhone too, so let's work on this together.
First, check out this article that helps you maximize your battery life:
Batteries - Maximizing Performance - Apple
After reviewing the info there, can you give me an idea of which apps are draining the battery on your iPhone?
You can go to Settings > Battery. Review the Last 24 Hours and Last 7 Days tab. Anything over about 15% is generally an app that's used a good bit of battery. Do you see anything unexpected there or an app you don't use a lot showing up there?
Let me know if your issue is resolved with the info in the Maximizing Performance article or if you find an app that's draining your battery.
Thanks for using Apple Support Communities.
