are activated by default to help you reduce battery consumption, and additional
power saving modes are available to help you reduce battery consumption further
when necessary.
Power saving features lower the priority for certain non-essential device functions,
such as higher grade image performance, network activities such as location
services, app synchronisation and background Wi-Fi scanning. If you do not want an
application to be affected, you can exempt it in the Battery optimisation 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 56.
•
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 45.
•
Change the synchronisation settings for your email, calendar and contacts, see
Synchronising with online accounts on page 52.
•
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 28.
•
Turn off the location-sharing permission for an application, see
Application
settings on page 57.
•
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 optimisation
Battery optimisation 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 optimisation, but you can make exemptions for certain
applications.
