    Mobile data or Wi-Fi suddenly turns off

    You might experience that the mobile data or Wi-Fi® connection stops working after the screen of your Xperia™ device has been turned off. One of the reasons that a mobile data or Wi-Fi® connection suddenly stops working may be that STAMINA mode has been activated automatically to save battery power.

    To solve the problem, try these actions one after the other. Verify after each action whether the problem was solved before trying the next one.

    • Try deactivating STAMINA mode, either manually or by connecting a charger to your device. If this solves the problem, STAMINA mode has most likely caused the connection to stop.
    • If deactivating STAMINA mode doesn't solve the problem, go to http://support.sonymobile.com/global-en/, select your device model, and enter My Wi-Fi connection keeps dropping in the search field. The troubleshooting article “My Wi-Fi® connection keeps dropping” will suggest a number of Wi-Fi® related solutions.
    • If the Wi-Fi® related solutions don't work, enter There is no network coverage or mobile data connection in the search field. The troubleshooting article “There is no network coverage or mobile data connection” will suggest a number of connectivity related solutions.
