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.

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
