When not in use, turn off Bluetooth, GPS, Wi-Fi, and Portable Wi-Fi hotspot
Note:
All of these features will frequently search for connections in the background while you aren’t using them. However, if Wi-Fi is available when using data, keep Wi-Fi on. 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.


  1. From the Start screen, touch the screen and slide left.
  2. Scroll down to and tap Settings.
  3. Tap Bluetooth.
  4. Tap the Status switch to turn off Bluetooth.
  5. Tap the Back key.
  6. Scroll down to and tap location.
  7. Tap the Location services switch to turn off.
  8. Tap the Back key.
  9. Scroll up to and tap Wi-Fi.
  10. Tap the Wi-Fi networking switch to turn off.
  11. Tap the Back key.
  12. Tap internet sharing.
  13. Tap the Sharing switch to turn off.

 

Toggle from LTE to 2G
Note:
Our LTE network gives you faster data, but can also use more battery, especially if the 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.


  1. From the Start screen, touch the screen and slide left.
  2. Scroll down to and tap Settings.
  3. Scroll down to and tap cellular.
  4. Tap the Highest connection speed field.
  5. Tap 2G.

 

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


  1. From the Start screen, touch the screen and slide left.
  2. Scroll down to and tap Settings.
  3. Scroll down to and tap phone update.
  4. Tap check for updates.
  5. If updates are available, follow any additional prompts to download and install.
  6. If necessary, wait as your phone restarts and updates.


Let it sleep

  1. Press and quickly release the Power key to put the device into sleep mode.
  2. To activate the screen, simply press and quickly release the Power key again.

 

Note: 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.
