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, a common term when it comes to battery performance, refers to the time during
which the phone is connected to the network and is not being used. The more time your phone
is in standby and not otherwise in operation, the longer the battery lasts.
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 > Wireless & networks > Mobile networks. 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 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 on the phone to see which applications consume the most
power. Your battery consumes more power when you use video and music streaming
