I keep my brightness set as low as I can - auto brightness off, location off - including system services - unless needed for video streaming apps, I keep wifi or cellular data on depending on what I'm using and turn the other off, turn off background app refresh for all apps, turn off cellular data for apps that only need it for ads and nothing else, lock my phone when I'm not using it, go though all setting and turn off anything I don't need or use, turn off iCloud since I don't use it, turn off notifications for apps that I don't want to receive notification for, I turn off Siri since VoiceOver does what I need to do so I don't use unneeded data, I turn LTE on only if I'm in an area with good LTE coverage, I have my date & time set to manual, I have everything turned off in the today view in notification center so only the date is showing, Bluetooth off, and I close my apps if I'm not using them.
I think that's it.
What I suggest to others to get the most out of your battery life is to turn off anything you don't need or use or is redundant.
