Using the touchscreen
A protective plastic sheet is already attached to the screen of your device when you buy
it. You should peel off this sheet before using the touchscreen. Otherwise, the
touchscreen might not function properly.
When your device 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
touchscreen when you are not using it. You can also set personal locks to protect your
subscription and make sure only you can access content on your device.
The device 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 warranty
service.

Zooming
The zoom options available depend on the application you are using.
•Place two fingers on the screen at once and pinch them together (to zoom out) or
spread them apart (to zoom in).
When you use two fingers on the screen to zoom, it is only possible to zoom if both fingers
are within the zoomable area. If you, for example, want to zoom in on a photo, make sure that
both fingers are within the photo frame area.
Scrolling
Scroll by moving your finger up or down on the screen. On some web pages you can
also scroll to the sides.
Dragging or flicking will not activate anything on the screen.

Sensors
Your device has sensors that detect both light and proximity. The light sensor detects
the ambient light level and adjusts the brightness of the screen accordingly. The
proximity sensor turns the touch screen off during voice calls when your ear is close to
the screen. This prevents you from unintentionally activating other functions on your
device when you are engaged in a call.
Battery
Charging the battery
Your battery is partly charged when you buy your device. It may take a few minutes
before the battery icon

charging. Charging your device over a long period of time, for example, overnight, does
not damage the battery or the device.

computer).
3Plug the other end of the cable into the micro USB port on your device, with the
USB symbol facing up. The notification light lights up when charging starts.
4When the notification light is green, the device is fully charged. Disconnect the
USB cable from your device by pulling it straight outward. Make sure not to bend
the connector when removing the cable from the device.
If the battery is completely discharged, it may take a few minutes before the notification light

Improving battery performance
The following tips can help you improve battery performance:
•Charge your device 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 mobile data connections from the
Notification panel by dragging down the status bar. This setting does not prevent your
device from transmitting data over other wireless networks.
•Turn off Bluetooth® and Wi-Fi® when you don't need these features. You can turn them
on and off more easily from the Notification panel by dragging down the status bar.
•Use the STAMINA mode and Low battery mode features to reduce battery
consumption. You can select the power saving mode that best suits the way you use
your device. You can also customize the settings of each power saving mode.
•Set your synchronization applications (used to synchronize your email, calendar, and
contacts) to synchronize manually. You can also synchronize automatically, but increase
the synchronization intervals.
•Check the battery usage menu in your device 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 applications downloaded from Google Play™
may also consume more power.
•Close and exit applications that you are not using.
•Lower the screen display brightness level.
•Turn off your device or activate the Airplane mode setting if you are in an area with no
network coverage. Otherwise, your device repeatedly scans for available networks, and
this consumes power.
•Use a Sony™ original handsfree device to listen to music. Handsfree devices demand
less battery power than your device's own loudspeakers.
•Keep your device in standby mode whenever possible. Standby time refers to the time
during which your device is connected to the network and is not being used.
•Disable any live wallpaper.

Using STAMINA mode
Activate the STAMINA mode feature to pause your Wi-Fi® connection, data traffic and
several power consuming applications when your screen is inactive. When STAMINA
mode is active, you can still receive phone calls, and text and multimedia messages. You
can also set up an applications list to allow some applications to keep running when your
screen is inactive. Once the screen becomes active again, all paused functions are
resumed.

Estimating the standby time of your device
Standby time refers to the amount of time the battery can last when your device is
connected to the network but is not in active use, for example, to receive or make phone
calls. STAMINA mode, when activated, continuously evaluates the remaining standby
time, which can vary depending on how you use your device. STAMINA mode is more
effective in lengthening the standby time if you keep the screen of your device locked. If
you rarely lock the screen, you may not see much improvement in battery performance.
When you use your device for the first time, the estimated standby time may not be accurate
since there is no previous usage history to estimate from.
To view the estimated standby time
1From your Home screen, tap .
2Find and tap Settings > Power management.
Using Low battery mode
You can activate the Low battery mode feature to save power when the battery level is
