So my phone kept random restarting and draining my battery. So I have found something that has fixed my phone. Go into your settings, power management, then turn everything off. the stamina mode, low battery mode, and queue background data. You can leave the wifi on. After I did this my phone has not restarted and my battery has improved alot. I hope this helps.</P><P>kevin</P> Wed, 04 Mar 2015 05:36:33 GMT https://community.sony.si/t5/xperia-archive/zl-random-shut-off-fix/m-p/3380084#M481763 Kevinj00 2015-03-04T05:36:33Z https://community.sony.si/t5/xperia-archive/zl-random-shut-off-fix/m-p/3380085#M481764 Boot on safe mode amd see if you experience the same issue<BR /><BR /><A href="http://talk.sonymobile.com/t5/FAQ/How-to-boot-your-phone-into-safe-mode/m-p/348008#U348008" target="_blank">http://talk.sonymobile.com/t5/FAQ/How-to-boot-your-phone-into-safe-mode/m-p/348008#U348008</A> Wed, 04 Mar 2015 06:39:39 GMT https://community.sony.si/t5/xperia-archive/zl-random-shut-off-fix/m-p/3380085#M481764 Uliwooly 2015-03-04T06:39:39Z
