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 further reduce battery consumption,
and additional power saving modes are available to help you reduce battery
consumption when necessary.
Power saving features lower the priority of certain non-essential device functions.
If you do not want an application to be affected, you can make it exempt in the
Power-saving exceptions menu. Phone calls and SMS are not affected.
System updates may change the power saving features available on your device.
To review and reduce your battery consumption
1 Find and tap Settings > Battery to view the estimated remaining battery
percentage and battery time.
2 Tap Advanced to view a list of applications and features that have
consumed battery power since the last charging cycle.
3 Tap an item to get information on how to reduce its battery consumption.
To view battery consumption for applications
1 Find and tap Settings > Apps & notifications > App info.
2 Select an application and review its battery consumption under Battery.
General usage tips to improve battery performance
The following tips can help you improve battery performance:
• Lower the screen brightness level, see
• 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
• Change the synchronisation settings for your email, calendar and contacts,
Synchronising with online accounts on page 50.
see
• 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
• Turn off the location-sharing permission for an application, see
settings on page 55.
• Uninstall applications that you are not using, see
page 22.
• 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.
