Battery and power management
Your device has an embedded battery. The battery consumption varies depending on
the features used. To make the battery last longer, you should consider the following:
•
Keep track of your battery consumption.
•
Follow the general usage tips to improve battery performance.
•
Use a power saving mode.
Your device is equipped with Battery saver and Android power saving features to
help your device to reduce its battery consumption. Android power saving features
run in the background and you can activate or deactivate Battery saver yourself.
The power saving features restrict background data to save power, so if you do not
want an application to be affected, you can exempt it in the Battery optimisation
menu.
System updates may change the available power saving modes 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 46.
•
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 29.
•
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 25.
•
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.
