Improving battery performance
The following tips can help you improve battery performance:
•
Charge your device 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.
This setting does not prevent your device from transmitting data over other wireless
networks.
•
Turn off Bluetooth™ and Wi-Fi® when you don't need these features. You can turn
them on and off more easily by adding the Quick settings widget to your Home
screen.
•
Use the STAMINA mode and Low battery mode features to reduce battery
consumption. You can select the power saving mode that best suits the way you use
your device. You can also customise the settings of each power saving mode.
•
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 your device to see which applications use the most
power. Your battery consumes more power when you use video and music streaming
