Sony Xperia E1 dual - Memory and Storage Management

Improving battery time using Location-based Wi-Fi®

but still have the convenience of automatic Wi-Fi® connections.
To activate the Location-based Wi-Fi® feature
1
From your Homescreen, tap .
2
Find and tap Settings > Power management.
3
Drag the slider beside Location-based Wi-Fi to the right.
Improving battery time by queuing background data
You can improve battery performance by setting your device to send background data at
pre-defined intervals when you're not using it, that is, when the screen is not active.

.

Find and tap Settings > Power management.

Memory and storage
Your device has different types of memory and storage possibilities for photos, apps,
and other files:
•
The
internal storage
is about
2
GB and is used to store downloaded or transferred
content along with personal settings and data. Examples are alarm, volume and
language settings, emails, bookmarks, call logs, contacts, messages, calendar events,
photos, videos, and music.
•
You can use a removable
memory card
of up to
32
GB to get more storage space. Most
applications can read data from a memory card but only certain apps can save files to
this type of memory. You can, for example, set the camera application to save photos
directly to the memory card.
•
The
dynamic memory (RAM)
is about
512
MB and cannot be used for storage. RAM is
used to handle running applications and the operating system.
You may have to purchase a memory card separately.

Improving memory performance
The memory in your device tends to fill up as a result of normal usage. If the device starts
to slow down, or applications suddenly shut down, you should consider the following:
•
Always have more than 100 MB of free internal storage and more than 100 MB of free
RAM.
•
Close down running applications that you are not using.
•
Clear the memory cache for all applications.
•
Uninstall downloaded applications that you don't use.
•
Transfer photos, videos, and music from the internal memory to the memory card.
•
If your device can't read content on the memory card, you may need to format it.
