I have a battery case that doubles my battery life. Typically, I get nearly 2 days out of the battery, and the case nearly doubles that. It's a uNu --

As stated before, changing your setting can make a world of a difference. I fetch email every hour, and have bluetooth turned off unless I use it. - both of these were mentioned above.
A couple of other tips:
- Turn off auto-brightness, and set your screen brightness manually.
- Under General / Accessibility, set Reduce Motion to ON. This stops the screen '3D effect' and saves battery life.
- In General, go through all apps and turn off background app refresh on all apps you don't need this. (Most apps don't really need this.)
- If you have social media apps, log out of these when you aren't using them.
- Turn off automatic downloads for all APPs. (Settings / iTunes & App Store). You will have to manually update apps - but that's not a big deal, and can save on battery life.
Here's a good rule of thumb to help save battery life: turn off stuff that is set to automatically update, especially on APPs where you don't need this. For example, do you really need the Angry Birds app to update you with the latest score board?
Hope this helps,
