I do! There is a battery saver option in the settings. It will turn on when your phone hits X% and I think you can change that percentage. I mainly adjust all my settings manually to extend battery life. Data and location are turned off unless I need them, brightness is low etc. You can set your mail so that it only updates and checks for new mail when you ask it to (and other tiles similarly).
