This chapter contains advice about prolonging the life of the battery in your phone,
managing the phone’s memory together with information about software upgrades.
Prolong battery life
Many features in your device increase the demand on battery power and reduce the
battery time between charges. To save battery power, note the following:
• Features that use Bluetooth technology, or allowing such features to run in the
background while using other features, increase the demand on battery power.
Deactivate Bluetooth technology when you do not need it.
• Features that use wireless LAN (WLAN), or allowing such features to run in the
background while using other features, increase the demand on battery power.
WLAN on your Vertu phone deactivates when you are not trying to connect, not
connected to an access point, or not scanning for available networks. To further
reduce battery consumption, you can specify that your device does not scan, or
scans less often, for available networks in the background.
• If you have set
Packet data
to

, and there is no packet data
coverage (GPRS), the device periodically tries to establish a packet data
connection. To prolong the operating time of your device, select

.
• If the signal strength of the cellular network varies much in your area, your device
must scan for the available network repeatedly. This increases the demand on
battery power.
• If the network mode is set to dual mode in the network settings, the device
searches for the 3G network. You can set the device to use only the GSM network.
To use only the GSM network, select
Menu

• The backlight of the display increases the demand on battery power. In the display
settings, you can change the length of the time-out period after which the backlight
is switched off. Select

• To save power, activate the power save mode. Press the
Power
key, and select
Activate power saving
. To deactivate it, press the
Power
key, and select
Deactivate power saving
. You may not be able to change the settings of certain
applications when the power save mode is activated.
Free memory

Many features of the device use memory to store data. The device notifies you if
available memory is low.
To free memory, transfer data to an alternative memory (if available) or compatible
computer.
You can also remove the following unwanted data:
• Messages in the folders in
Messaging
and retrieved email messages from the
mailbox.
• Saved web pages.
• Contact information.
• Calendar notes.
• Applications shown in
Applications manager
that you do not need.
• Installation files (with .sis or .sisx file extensions) of installed applications. Back up
the installation files to a compatible computer.
• Images and video clips in
Photos
.
