    Power and vol+ force reboot, not shutdown, to force shutdown u need to push the tiny red button in the sim location.
    I suggest you to reflash your phone with a tft file or with SUS, 4.4.2 brings many drain battery problems.

    I've already ask this question on sonymobile forum, but have no result. Trying to post it here.

    I upgrade my Z1 to 4.4.2 and get the next issue.
    When I switch off my phone with long press power button -> "swich off phone", its successfully shutting down but after 5-10 sec. show startup SONY logo then swich off display then show logo again and so on endlessly...
    It was very unexpectedly, when I swich off Z1 and put it into pocket, after cuple of days I found it totally discharged. I cant make phone alive with wall charger and only 2-3 hours on USB charger can reanimate Z1.
    I was try everything what I read no docs and forums, reflash with SUS and sony PCC, flash different versions of FTF via flashtool, boot on safe mode etc, but nothing helps :(

    Is there software problem with shutdown loop or problem with battery controller or something else? How can I fix it? Any considerations?

    P.S. Small "force shutdown" button or Power+VolUp combination sometimes helps to shutdown phone.

    Try to start from scratch:
    1. Wipe internal sdcard
    2. Eject (pull out) you external sdcard
    3. Re-flash FTF (don't thick anything, let it default flash configuration)
    4. Don't try to restore any app or data from old firmware version.
    5. Check if the problem still persist

    I had something similar to your problem and solve it by connecting the phone to flashtools in fast boot (power button + volume + button) so after selecione check current device status and ready the phone restart and recovery I could enter and there you restore the phone and stay as before hope you serve anything we are here
