I've noticed my battery is draining faster since the update. Are there any settings I should adjust or tips to help extend battery life?

You can look at this:

Batteries - Maximizing Performance - Apple

Note that inmmediately after doing an update, the phone has lots of background tasks to finish that may take more battery life.

You can see what is using battery in Settings > Battery
