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.
You can do this from
Settings

>
Mobile networks
>
Data traffic
. This
setting does not prevent your device 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 Quick settings 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 device to see which applications use the most
power. Your battery consumes more power when you use video and music streaming
applications, such as YouTube™. Some Android Market™ applications also consume
more power.
•
Close and exit applications that you are not using.
•
Lower the screen display brightness level.
•
Turn off your device or use
Airplane mode
if you are in an area with no network
coverage. Otherwise, your device repeatedly scans for available networks, and this
consumes power.
