Apologies i put that on the wrong forum, I've been following a few with the same issue.
Yes I'm a Z5 owner,
And for what it's worth still have the battery issue.

Found a solution to my problem, WiFi calling and doze mode working. I have the latest update installed 32.3.A.2.33 and i disabled VoLTE. VoLTE is causing the kernal to wake-up the phone all the time when the screen is off, draining my battery. Hope this helps 😁

Can you elaborate how to turn off VoLTE on xperia XZ ?
I haven't able to find this option in settings.
What helped me a bit is to perform Factory reset to Nougat 7.0 without the SD card.
This defenetly helped with battery life - phone idle dropped from ~20% to around 15% in average.

I should be in settings/ call settings, but i belive it's not supported on the XZ anyway.
A reset heled me as well.
Also there's the option for the smartwatch companion app to run all the time, or not.
Letting it run in the background reduces battery life. Still usable, but deifnelty worst.

I don't think LTE is the issue, mine is always on (WIFI always OFF, because i use LTE) and it draws 2-3% for 8hr standby (night).

How to update it? I am on 7.0 and my z5c is useless, because the battery drain. I wish to have back my z1c...

Like i said, this solved my problem. I'm using a z5 compact, bad battery drain, WiFi calling disappearing and doze not working. My VoLTE is in settings>data usage>three dots in the top right hand corner>select mobile networks from the drop down menu.
Edit: i just read the other replies and you guys are right, the xz duel doesn't support VoLTE.
Are any of you using betterbatterystats?
