Battery and Power Management
Your device has an embedded battery. To get the most use from it, keep track of the
power consumed by different apps and features. Background power-saving features 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
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.

•
Lower the screen brightness level, see
Screen settings
on page 60.
•
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 50.
•
Change the synchronization settings for your email, calendar, and contacts, see
Synchronizing with Online Accounts
on page 56.
•
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 32.
•
Turn off the location-sharing permission for an application, see
Application
settings
on page 62.
•
Uninstall applications that you are not using, see
Application screen
on page 27.
•
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.
