An Android™ phone can perform many of the same functions as a computer. But you can
also adjust it to better suit your needs, to receive the information you want, and have fun
at the same time. You can add and delete applications, or enhance them to improve
functionality. At Android Market™ you can download a range of applications and games
from a constantly growing collection. You can also integrate applications on your Android™
phone with your personal data and online accounts. For example, you can back up your
phone contacts, access your different email accounts and calendars from one place, keep
track of your appointments, and engage in as much social networking as you like.
Android™ phones are constantly evolving. When a new software version is available and
your phone supports this new software, you can update your phone to get new features
and the latest improvements.
Your Android™ phone is pre-loaded with Google™ services. To get the most out of the provided
Google™ services, you should have a Google™ account and sign in to it when you first start
your phone. You also need to have Internet access to use many of the features in Android™.
Applications
An application is a phone program that helps you perform a task. For example, there are
applications to make calls, take photos and download more applications.
Insert the tip of your finger firmly into the opening on the bottom side of the phone,
between the phone and the battery cover. Then lift up the cover slowly but firmly.

Charging the battery
Your phone battery is partly charged when you buy the phone. It may take a few minutes
before the battery icon appears on the screen when you connect the phone charger
cable to a power source, such as a USB port or a phone charger. You can still use your
phone while it is charging.
The battery will start to discharge a little after it is fully charged and then charges again after a
certain time when the phone charger is connected. This is to extend battery life and may result
in the charge status showing a level below 100 percent.
To charge the phone
1
Plug the phone charger into a power outlet.
2
Plug one end of the USB cable into the charger (or into the USB port of a computer).
3
Plug the other end of the cable into the micro USB port on your phone, with the USB
symbol facing up.
4
When the phone is fully charged, disconnect the USB cable from your phone by
pulling it straight outwards.
Make sure not to bend the connector when removing the cable from the phone.
Using the touch screen
A protective plastic sheet is attached to the screen of your phone when you buy it. You
need to peel off this sheet before using the touch screen. Otherwise, the touch screen might
not function properly.
When your phone is on and left idle for a set period of time, the screen darkens to save
battery power, and locks automatically. This lock prevents unwanted actions on the touch
screen when you are not using it. You can also set personal locks to protect your
subscription and make sure only you can access your phone content.
Your phone screen is made from glass. Do not touch the screen if the glass is cracked or
shattered. Avoid trying to repair a damaged screen yourself. Glass screens are sensitive to drops
and mechanical shocks. Cases of negligent care are not covered by the Sony Ericsson warranty
service.

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 synchronisation applications (used to synchronise your email, calendar and
contacts), to synchronise manually. You can also synchronise 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.
•
Close and exit applications that you are not using since multitasking affects the battery
performance.
•
Lower the screen display brightness level.
•
Turn off your phone or use Airplane mode if you are in an area with no network coverage.
Otherwise, your phone repeatedly scans for available networks, and this consumes power.
•
Use a Sony Ericsson original handsfree device to listen to music. This consumes less battery
power than when you listen to music through the phone's loudspeakers.

www.sonyericsson.com/support.

Memory card
You may have to purchase a memory card separately.
Your phone supports a microSD™ memory card, which is used for media content. This
type of card can also be used as a portable memory card with other compatible devices.
Without a memory card you cannot use the camera, nor can you play or download music files
and video clips.
Formatting the memory card
You can format the memory card in your phone, for example, to free up memory. This
means that you erase all data on the card.
All content on the memory card gets erased when you format it. Make sure you make backups
of everything you want to save before formatting the memory card. To back up your content, you
can copy it to your computer. For more information, refer to the chapter Connecting your phoneto a computer on page 98.

traffic counter is reset on the 15th day of every month. The first time you start the Data
monitor, the start day is set to 1.
Get the Data monitor to alert you when the amount of transferred data reaches a certain
limit. You can set limits separately for sent data, received data and total data. You can also
