I recently just got the 6 plus and my battery life is not all that great. I need some suggestions as to what I can do or turn off to improve the battery life. Thanks

Turn off the APPS that are running in the background.

It totally depends upon how would you use you iPhone 6...Thus you cannot do any thing about it..except you can install an app which close your background running apps..

If you are jailbroken I would suggest you get iCleaner pro from Cydia. I would also suggest getting Phone Doctor plus to help save battery

Also you can set individual settings for each application on your device to use/not use mobile data, background refresh etc etc. changing these WILL make your battery last longer

And don't forget that turning off wi-fi and bluetooth when you aren't using them will save a lot of battery life.

You can also check which apps are using the most battery under Settings -> Battery. Tap the clock icon and it will show you how many minutes each app used and whether it was foreground or background - that will help a lot.

I have to admit that I've been pleasantly pleased with my battery life myself. I do a lot of reading on my phone (5-6 hours per day avg), and yet I find I can go 2-3 days between charges without the phone getting below 40%. I'd never be able to do that on my old phone.
