HTC One Remix - Manual (Page 76)

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.
§ When you’re not traveling from one place to another, sync weather
updates of only your current location, rather than in all of your
named cities. Open the Weather app, and then tap to edit and
remove unneeded cities.
§ Choose widgets wisely.
Some widgets constantly sync data. Consider removing the ones
that are not important from your Home screen.
§ In Play Store, tap > Settings, and then clear Add icon to Home
screen to avoid automatically adding Home screen app shortcuts
whenever you've installed new apps. Also tap Auto-update apps >
Do not auto-update apps if you're fine with updating apps from
Play Store manually.
