Extending the Battery Life

Active applications, screen brightness levels, Bluetooth and Wi-Fi usage, and GPS functionality can drain your battery. You can follow the helpful tips below to conserve your battery power:

 Reduce the screen backlight time.  Lower the screen brightness.  Turn auto sync and Bluetooth off when not in use.  Disable the GPS function when not in use. Most applications

using this function will periodically query the GPS satellites for your current location; each query drains your battery.

 Use the power saver feature.

NOTES:

 Screen lock options are listed in the approximate order of the

strength of their security, starting with None and Swipe, which provide no security. A pattern provides minimal security, although it can be more convenient than the stronger options.

 Remember the pattern, PIN or password you set. Otherwise,

you will have to upgrade the phone software to use the phone.

Protecting Your Phone With Encryption

You can encrypt all the data on your phone: your accounts, application data, music and other media, downloaded information, and so on. If you do, you must draw an unlock pattern, or enter a numeric PIN or a password each time you power on your phone.

WARNING!

Encryption is irreversible. The only way to revert to an unencrypted phone is to perform a factory data reset, which erases all your data.

Encryption provides additional protection in case your phone is stolen, and may be required or recommended in some organizations. Consult your system administrator before turning it on. In many cases the pattern, PIN or password you set for encryption is controlled by the system administrator.

Before turning on encryption, prepare as follows:

 Set a screen lock pattern, PIN or password.  Charge the battery.
