Hi @aiyaya, sorry to hear about this.

Is there any indication in the device when it turns off? For example, does it say that the battery level is low?

After the device have shut down and it starts restarting over and over again, are you ever able to power it on again? If you are, what do you need to do in order for it to start up again?

Keep me posted!

hi i have exactly the same problem with my xperia z5 as

Same problem with my Z5 Compact, did a restart on it this morning now the phone just keeps trying to start up then shuts down in an endless loop. Only way I can turn it off is to use the small button next to the sim card slot, but if I turn the phone on again it goes back into the endless start-stop cycle. Any suggestions for a fix please?

@po10ci, sorry to hear that.

Have you tried any of the two resets found on the link below? If you haven't done that, please do.

@Horizonti, sorry to hear about your device not starting up.

Can you try and remove the SIM and/or SD cards and see if that makes any difference? Should there be no change, try performing a software repair using Xperia Companion.

Keep me posted!

Hi Jonas, thank you for the reply. I spoke with Stephanie in customer service who sent me a very easy set of instructions and I did a software repair and am now back up and running with no loss of contacts. I'm very impressed with the help so thanks to all.

Regards. Horizonti.

Hi again @Horizonti2!

That is awesome news and you're very welcome!

Sounds like you perhaps had the contacts saved to your Google account and they were restored when you added your account again.

Have a fantastic day and let me know if there is anything else!
