If your Droid DNA is consuming data and battery life, then here are some important tips you can follow to fix these issues. Make sure you are not syncing your photos and videos to the cloud for backup. Make sure auto-sync is turned off if you have Dropbox, Google Drive, anti-virus products, etc. Verizon may have have also included apps that auto sync. Go into Settings then sync settings to turn off auto syncing apps. Also consider using an app like Greenify, which allows you to hibernate apps that are running in the background.
