Tips to save battery life

To save and extend battery life, follow these steps:


Lower screen brightness and backlight duration

Most Android devices come with high resolution touch screens. This is one of the biggest drains on your battery.


To lower the brightness and duration, go to Menu>Settings>Display (or Sound & Display) and look for Brightness and Screen Timeout.

Note: Some devices have the option for ‘Automatic Brightness’. This brightens and dims the screen based on your current environment.


Turn off Bluetooth, GPS, Wi-Fi, and Portable Wi-Fi hotspot when not in use.

All of these features will frequently search for connections in the background while you aren’t using them. To turn these features on and off, go to Menu>Settings>Wireless.

Note: These settings can be accessed quickly by using the Power Control widget. To add this widget, touch and hold an empty space on the Home screen, touch Widget, and touch Power Control.

If Wi-Fi is available, use it: Using Wi-Fi not only saves your mobile data usage, it also can be a more power-efficient way to use data instead of using your mobile network.


Change application sync settings

Keeping a constant feed from your social networks and e-mail accounts can cause your phone to be constantly interacting with the mobile network. Reducing the frequency that applications and e-mail accounts update can preserve battery life.


Turn off automatic synchronization and sync your e-mail and calendar manually. To change these settings go to Menu>Settings>Accounts & Sync (or Data Synchronization), select the account you want to change, and select Update Schedule.


Turn off Background Data.

Aside from registered accounts with Google and T-Mobile Contacts Backup, your downloaded applications frequently update and can rapidly drain battery life. If the option is available, reduce the sync frequencies for these applications.


Minimize use of third-party applications:

Using applications can enhance your phones functionality, but they can also use up valuable battery life – especially if they keep your screen on, or require a data connection. Some applications are best used when the device is plugged in.

Note: If you battery life decreases significantly in a short period of time – consider any recent downloads that may have started the problem, and uninstall them.


Toggle from 4G to 2G

Our 4G network gives you faster data, but can also use more battery, especially if the 4G signal is weak. If you aren’t using data, leave your phone on 2G until you need it again. You will still be able to make and receive calls and browse the web at slower speeds while on 2G.


To change this setting, go to Menu>Settings>Wireless & Network (or Wireless Controls) and select GSM Only. To change back to 4G, select WCDMA/GSM Auto.


Update to the Latest Software

Always make sure your device has the latest software version available. Device manufacturers and Google will release updates to the device operating system, often improving battery life as one of the benefits.


To check for system updates go to Menu>Settings>About Phone and look for System Updates, Google Software Updates, or Manufacturer Software Updates.


Let it sleep

Be sure to put your phone into a sleep or standby mode when the device is in a pocket, case, or purse. Putting the device into sleep mode will keep you from unintentionally activating applications or illuminating the screen.


On most devices, this is done by tapping the power key.


Leave it plugged in

Your device should have a Lithium-based battery which means that leaving it on the charger will not damage the battery, even if it is already fully charged. Take advantage of AC power sources when they are available at home or at work for extended periods of time.


You should only use chargers that are approved by the manufacturer.


Calibrate the battery meter

Allow battery to die completely so that phone turns off due to lack of power.  Charge with the wall charger that came with the phone until charge is 100% complete.  Repeat procedure.  You should not have to complete this process more often than once a month.


Close battery-intensive programs, such as the Camera, when you are done using them.


Third-party applications may also drain the battery quicker.

If battery life diminishes significantly after installing applications from the Play Store, perform the following to determine the application causing the problem:

  1. Open Play Store.
  2. Tap Menu.
  3. Tap My Downloads.
  4. Scroll through and review your installed applications for the following information:
    • If any apps are out of date, then update them
    • Low ratings (1 or 2 stars)
    • Comments indicating battery issues
    • Wi-Fi, Bluetooth, GPS, or network access
      • Note: Tap Security Permissions to see the application's current access.
  5. If your battery drains quickly, it is highly recommended to uninstall the application.


Note: Third party applications that use advertisements instead of payment for the application can often cause additional battery drain on a smartphone. If you are using advertising-only applications, purchasing or uninstalling the applications may increase battery life.
