Improving battery performance
The following tips can help you improve battery performance:
•
Charge your phone often. This will not affect the lifetime of the battery.
•
Downloading data from the Internet is power consuming. When you're not using the
Internet, you can save power by disabling all data connections over mobile networks.
You can do this from Settings > More... > Mobile networks > Data enabled. This
setting does not prevent your phone from transmitting data over other wireless
networks.
•
Turn off GPS, Bluetooth™ and Wi-Fi® when you don't need these features. You can
turn them on and off more easily by adding the Status switch widget to your Home
screen. You do not need to turn off 3G.
•
Set your synchronisation applications (used to synchronise your email, calendar and
contacts) to synchronise manually. You can also synchronise automatically, but
increase the synchronisation intervals.
•
Check the battery usage menu in the phone to see which applications use the most
power. Your battery consumes more power when you use video and music streaming
