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.
• Turn off Bluetooth® and WLAN 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. Some applications 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.
If you are using a device with multiple users, some tips may only be applicable to the owner,
that is, the primary user of the device.
