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.
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.

Memory
You can save content on a memory card and in the phone memory. Music, video clips,
and photos are saved on the memory card while applications, contacts, and messages are
saved in the phone memory.
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 can't 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 phone
to a computer on page 69.
