How can I extend my battery life?
Your particular usage will affect how long you can go before recharging your battery. Navigating, playing
games, surfing the Web, making calls and texting all use energy. You can install and use a wide variety
of applications on your device, and each application has its own characteristics.
Thus your experience may vary day to day, depending on how you use your device.

Depending on your preferences, you can tailor how your device behaves by using some of the following
tips:
Charge each night so you start the day fully charged and ready to go.
You can see what subsystem, component, or application is using the most power: Touch >
Settings > Battery
If you are stationary in an area in which there is low or no cellular signal, it may be prudent to
enter airplane mode unless you must be able to (try) to make or receive calls or texts. Doing so
will prevent the phone from increasing power output in an attempt to connect to the weak
signal.
When setting the phone down after use, quickly press the power key to turn the display off.
Set Screen timeout less then 1 minute: From the Settings menu, scroll down and tap on Display
and then tap on Sleep to select a faster time-out.
Turn off applications actively using GPS, such as navigation applications when you no longer
need them. It is easy to forget to 'end navigation' when you reach your destination. Swipe
down from the notification bar to see if active navigation applications offer an option to quit or
exit. You can also adjust the locate mode to try and conserve battery life: Settings > Security &
Location > Change the mode to Battery saving
Applications: some applications and widgets can use a lot of energy when you use them. Others
can also behave in a non-battery friendly manner when you are not using them. Apps that use a
lot of wireless data (streaming Video or Music, navigation/maps, etc) will take more out of your
battery because the wireless radios have to transmit and receive a lot of data. Applications that
have frequent updates (social applications, email, IM, etc.) are also active energy
consumers. Some live wallpapers and widgets may also be consuming power. In general,
observe how long your battery lasts relative to the applications that you are using. There are
many system utility applications on the Play Store that can help identify how apps consume
resources (power, data, memory) for those so inclined to dig deeper.
A quick and easy step is to reboot your phone if you have not turned it off in a long time (> 1
week), or if you feel it has become sluggish and its battery life is not what you expected. Press
and hold the power key to select the Power Off option. Then turn your phone back on and
charge your phone normally. Frequent reboots can help keep poorly behaved applications from
using more than its share.
Wi-Fi: in broad terms, data over Wi-Fi uses less energy than data over cellular (and will also save
on usage if you have a cap). However if Wi-Fi is not available you may choose to turn it off as
well: Swipe down from the top of the screen, and tap the quick setting Wi-Fi Off.
