Hi all,
This happened:
After I picked up my phone in the morning (from charger), it had turned itself of during the night. After using it a while it started rebooting itself. This occures now very often. This happens with a lot of battery % left. Sometimes it restarts, and sometimes it just stops. When it stops I have to put the charger in to restart it, even it the battery seems to be fully charged. Can be an issue when I`m not at home.
I have notised that the battery % varies sometimes. It can co from 4 - 100 % in minutes while connected to the charger (Sony charger)
I have tried this.
- VolumeUP/Home button.
- Red button in Sim slot.
- PCC resetting
The phone was upgraded to Lollipop about one month before this occured. Have been working fine after the upgrade.
Can this be an battery issue?

Solved! Go to Solution.
Connect the phone to a wall charger > press and hold power & volume up for 10 seconds > let it charge for 2 to 3 hours
Thanks for your reply @uliwooly. Already tried that after reading about similar problems. Didn`t solve it unfortunately.
I'm sorry to hear that, contact your local Xperia Care
My warranty period is over, so that will cost me a fortune. 
Battery is ordered.
Will wright back and tell if this will solve my problem.
This was my sollution:
Ordered a new battery on Ebay. Installed and my phone is itself again.
The strange thing was that the problems that I experienced seemed like a software issue when I read about simmular problems here on the forum. Hopes this can help others as well.

I thought the Z1 was a sealed unit? How can you change the battery yourself?
I am having similar problems......just about to try a factory reset first to see if that helps......
