See Updating the Droid DNA by HTC software on page 27. § Uninstall or disable apps that you never use. Many apps run processes or sync data in the background even when you're not using them. If there are apps that you don't need anymore, uninstall them. If an app came preloaded and can't be uninstalled, disabling the app can still prevent it from continuously running or syncing data. In Settings, tap Apps > All tab, select the app, and then tap Disable. Limit background data and sync Background data and sync can use a lot of battery power if you have many apps syncing data in the background. It's recommended not to let apps sync data too often. Determine which apps can be set with longer sync times, or sync manually. § In Settings, tap Accounts & sync and check what types of data are being synced in your online accounts. When the battery is starting to run low, temporarily disable syncing some data. § If you have many email accounts, consider prolonging the sync time of some accounts. In the Mail app, select an account, tap > Settings > Sync, Send & Receive, and then adjust the settings under Sync schedule.
