as higher-grade image performance, network activities such as location services, app
synchronization and background Wi-Fi scanning. If you do not want an application to be
affected, you can exempt it in the Battery Optimization menu. Phone calls and SMS are
not affected.
System updates may change the power saving features available on your device.

General Usage Tips to Improve Battery Performance
The following tips can help you improve battery performance:
•
Lower the screen brightness level, see
Screen settings
on page 55.
•
Turn off Bluetooth®, Wi-Fi, and location services when you don't need these
features.
•
Turn off your device or use Airplane mode if you are in an area with no or low
network coverage. Otherwise, your device repeatedly scans for available
networks, and this consumes power.
•
Use a Wi-Fi network instead of roaming when abroad. Roaming is scanning for
your home network and puts additional demands on your battery as your device
must transmit with a higher output power, see
Wi-Fi
on page 44.
•
Change the synchronization settings for your email, calendar, and contacts, see
Synchronizing with Online Accounts
on page 51.
•
Check the applications that have a high battery consumption and consider the
battery saving tips provided on your device for these applications.
•
Change the notification level for an application, see
Notifications
on page 27.
•
Turn off the location-sharing permission for an application, see
Application
settings
on page 56.
•
Uninstall applications that you are not using, see
Application screen
on page 24.
•
Use a Sony™ original handsfree device to listen to music. Handsfree devices
consume less battery than your device's loudspeakers.
•
Restart your device every now and then.
Battery Optimization
Battery optimization is a powerful and convenient built-in mode which improves your
battery life significantly by reducing battery consumption when you are not using the
device or certain apps.
This is achieved by suspending battery draining network activities, such as location
services, syncing, and Wi-Fi scanning in the background when you have not been using
your device for a long time.
Phone calls and SMS messaging are not affected.
You cannot disable Battery optimization, but you can make exemptions for certain
applications.
