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. You can also use Battery Care to

increase the battery’s lifetime. 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.

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 59.

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 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 29.

Turn off the location-sharing permission for an application, see

Application

settings

on page 61.

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.
