• Lower the screen brightness level, see Screen settings on page 58.
• 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 49.
• Change the synchronisation settings for your email, calendar and contacts, see
Synchronising with online accounts on page 55.
• 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 29.
• Turn off the location-sharing permission for an application, see Application
settings on page 60.
• 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 exempt applications from being
optimised.
To make specific applications exempt from battery optimisation

an application from the list to edit its optimisation settings.
5 The list of applications that are not optimised will get updated according to
your settings.
You cannot exempt applications from being optimised by Ultra STAMINA mode.
You can also configure Battery optimisation from the Apps menu by tapping > Special
access.
