Battery
Your Android™ phone keeps you connected and updated wherever you are. This affects
the battery life of your phone. Below are some tips on how to prolong battery life while still
staying connected and up to date.
Battery performance
Standby time is the amount of time the battery can power your phone when calls are not being
received or made. The more time your phone is in standby, the longer the battery lasts.
The following tips can help you improve battery performance:
•
Charge your phone often.
•
Downloading data from the Internet is power consuming. Turn off all data connections by
disabling the Data traffic option from the status bar when you're not using the Internet.
•
Set synchronization applications (used to synchronize your email, calendar and contacts),
to synchronize manually. You can also synchronize automatically but increase the 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 applications
such as YouTube™. Some Android Market™ applications also consume more power. Limit
your use of such applications if your battery is running low.
•
Increase the interval between updates or set the interval to manual for Facebook™ and
Twitter™ updates.
•
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 Power control widget to your Home screen. You
do not need to turn off 3G.
