Battery performance
The standby time is defined as the time when the phone is connected to one network operator
and located in a place where it has full network coverage and a strong signal strength. The
standby time may vary depending on your position in the network and the signal strength. The
more time your phone is in standby, the more the battery lasts.
The following tips will help you improve battery performance:
•
Charge your phone often.
•
Turn off WLAN and Wi-Fi® when not using these functions. You do not need to turn off
3G.
•
Some of the applications from the Android™ Market affect your battery performance. It is
recommended to check, which applications consumes more battery in the battery usage
menu in the phone, which can be accessed from Settings > About phone.
•
Set synchronisation applications like RoadSync™ in the phone to synchronise manually.
You can synchronise automatically but change the intervals.
•
It is recommended to reduce the update frequency or set it to manual for applications which
require that the network connection is updated continuously, such as Facebook™ and
Twitter™.
•
If you are not using applications that use GPS, such as Google Maps™, you should disable
GPS.
•
It is recommended to temporarily turn off your phone, if you are in an area with no network
coverage. Otherwise, your phone repeatedly scans for available networks, which consumes
power.
•
Add the Power control widget to the Home screen to easily turn on and off Wi-Fi®,
Bluetooth™ wireless technology, GPS, background data and display brightness.
To add the Power control widget, press
, then tap Arrange widgets > Add widget and select
Power Control.
