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 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 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.
•
To access the battery usage menu
From your Home screen, tap
