    Battery and power management

    Arrow left Xperia Z3 support overview

    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 synchronisation and background ‎Wi-Fi‎ ‎scanning. If you do not want an application to be affected, you can exempt it in the Battery optimisation menu. Phone calls and SMS are not affected.


    System updates may change the power saving features available on your device.

    To view battery consumption, estimated time, and power saving tips

    1. From your Home screen, tap Icn sony home apptray normal.
    2. Find and tap Settings > Battery. An overview appears showing the battery percentage and an estimated battery time.
    3. Tap SHOW BATTERY USAGE to view a list of features and services that have consumed battery power since the last charging cycle. Tap an item to get information on how to reduce its battery consumption.

    To view battery consumption for applications

    1. From your Home screen, tap Icn sony home apptray normal.
    2. Find and tap Settings > Apps.
    3. Select an application and review its battery consumption under Battery usage.

    General usage tips to improve battery performance

    The following tips can help you improve battery performance:
    • Lower the screen brightness level, see Screen settings.
    • 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 .
    • Change the synchronisation settings for your email, calendar and contacts, see Synchronising with online accounts.
    • 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.
    • Turn off the location-sharing permission for an application, see Application settings.
    • Uninstall applications that you are not using, see Application screen.
    • 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

    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 device or certain apps.

    This is achieved by suspending battery draining network activities, such as location services, syncing and ‎Wi-Fi‎ ‎scanning in the background when you have not been using your device for a long time.

    Phone calls and SMS messaging are not affected.

    You cannot disable Battery optimisation, but you can make exemptions for certain applications.

    To make specific applications exempt from battery optimisation

    1. From your Home screen, tap Icn sony home apptray normal.
    2. Find and tap Settings > Battery.
    3. Tap Icn sony key menu and select Battery optimisation. You will see a list of applications that are not optimised.
    4. To add or remove applications from this list, tap Apps and select or de-select an application from the list to edit its optimisation settings.
    5. The list of applications that are not optimised will get updated according to your settings.


    You can also configure Battery optimisation from the Apps menu by tapping Icn sony menu settings.

    Power saving modes

    There are several power saving modes available for you to use if you want to make your battery last longer:

    STAMINA mode
    Depending on the STAMINA level, different features will be restricted or disabled in order to reduce battery consumption. These include rendering performance, animation and screen brightness, image enhancement, background app data syncing, vibration (except for incoming calls), streaming and GPS (while the screen is off). Icn sony stamina on appears in the status bar.

    To activate or deactivate STAMINA mode

    1. From your Home screen, tap Icn sony home apptray normal.
    2. Find and tap Settings > Battery.
    3. Tap STAMINA mode and tap the slider to activate or deactivate the function. When STAMINA mode is activated you can select additional options, for example you can adjust the Auto-start percentage according to your preferences.


    You can exempt applications from being optimised by STAMINA mode in the Battery optimisation menu.

    To activate Ultra STAMINA mode

    1. From your Home screen, tap Icn sony home apptray normal.
    2. Find and tap Settings > Battery.
    3. Tap Ultra STAMINA mode and then tap Activate .
    4. Confirm to activate.


    You cannot exempt applications from being optimised by Ultra STAMINA mode.
