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 data connections over mobile networks.
This setting does not prevent your device from transmitting data over other wireless
networks.
•
Turn off Bluetooth® and Wi-Fi® connections 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 customise the settings of each power saving mode.
•
Set your synchronisation applications (used to synchronise your email, calendar and
contacts) to synchronise manually. You can also synchronise automatically, but
increase the synchronisation 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 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.

connected to the network but is not in active use, for example, to receive or make
