The Sony Xperia Z may be a nice feature packed phone. However with an operating system like android that’s open to any range of customizations and tweaks all around, there are probabilities that a handful of recent launcher or app installs may get your phone to the not responding state.

In such a scenario, restarting the Xperia Z in a forced manner can not be done by directly plugging out and putting the battery in because the back battery panel is closed and therefore the battery isn’t removable. To go concerning doing that, here’s a small fix you’ll follow:

Force to Restart Xperia Z Smart Phone with Built in Battery


  1. Press and hold the power button for or five at the side of the volume up key.
  2. Remove your finger once you feel the vibration then press and hold the volume up button for ten seconds.
  3. Now the phone begins to shut down automatically with a three-pulse vibration try.
  4. Now turn the phone on once more normally as you are doing and also the phone has restarted.

Though the external battery removal choice isn’t on the market, there’s a way to force restart the Sony Xperia Z. Allow us to know how it went within the comments?

    I couldnt get it to restart so I pressed the on/off button AND the volume up button at the same time. When I felt the vibrating the phone restarted.

      I second this. Just holding the power button down didn’t seem to have any effect.

      I also just had to do the same thing. Worked after pressing power AND volume

      1. Prathibha Gamage

        My phone was not responding at all. No screen, no vibration, only the white color LED. Holding the power button didn’t work. So as Kim suggested, I pressed and hold both ppower and volume up buttons and it worked!

    I did only 2 first steps and my xperia restarted, but it has got low battery now (3%). It’s a little bit strange, because when I went to sleep, it had 35%

    I pressed the power button and the volume up button at the same time for about 5-7 seconds. The phone shut down and I was able to do a normal startup.

    As per other comments being left, maybe the spelling, and instructions need updated slightly. Hold power key , then hold volume up key. Let go of both when phone vibrates, and should then re-boot. Appears to have got rid of some of the lag I was experiencing.

      thanks bro this helped…. it was sure some lag or somethin and also anothr option is to try transfering ur data from internal memory to ur external memory so that ur operating system gets enuf of internal memory to run smoothly…. this lag happns mostly bcuz v full the internal memory wid our downloads and forget to transfer them to our external memory… once ur internal memory has enuf space the phone should run smoothly….. peace!!

    First…i was worried when my Xperia “freeze”, i had pushed the power button for long time but nothing was happened. I follow your instruction by holding power & volume up button at the same time for about 3 seconds…and whoila! my phone shut down and i can restart…now it back to normal condition…thank you very much for your very good advice ^_^

    Thanks a million. Found lots of articles mainly saying to hold the power and up button at the same time and that does not work for me. Your procedure was different to those so I tried it and it worked. I did not get a vibration above but by just holding the power button for a few seconds (I had it pugged into a USB slot on my laptop) a red light appeared in the top right corner which indicated some life in the phone. Then holding the vol up for about 10 secs did the trick and after letting go I then got the vibration. Pressing power then started the phone. Excellent article.

    used this a few times now works perfectly. very rare my phone will crash as its a amazing phone!!

  11. Alex Vo

    If none of the button combos work! Then take out SIM card. Mine then auto restarted.

    +1: I couldnt get it to restart so I pressed the on/off button AND the volume up button at the same time. When I felt the vibrating the phone restarted.

  15. Remi

    Thanks Kim It totally worked

  16. charan

    yes with power button we have to press volume upwards then only the ph will restart.

  17. Kos Panikos

    yeah..power and volume up altogether

  18. Kate

    ive done absolutely all the tips and tricks everyone has offered. my phone still wont turn on or anything. when i have it on charge there is a solid red light, i leave it for a few mins and try the volume and power button technique, still nothing. This is the second time this has happened to my phone (the first time i was able to resolve it). What a piece of junk! My phone doesnt even have a restart button.. The fact that this phone even needs a well known “method” to turn it on, proves that it has had problems from the moment it was made. STUPID, STUPID, STUPID. IT is no longer a phone but a huge piece of junk! thanks for wasting my time SONY

    I had a bit of a pickle when my phone alarm went off while I was listening to music, and the screen wouldn’t respond to touch. I couldn’t do anything because the alarm app overlayed everything! In the end I decided to try this, but the real way to do it is both the power button and the up volume key pressed down at the same time. I got the restart after that, and now my alarm isn’t blaring out at me!
