diminished battery power with update (Z5 Premium/dual)

[musique101]

Good things doesn't last forever.  

I was very excited to see the latest update with stamina mode but now I'm regretting it.  I'm not a heavy user at all and used to get by 2-3 days easily without charing.  After the update....there is no juice left on the phone! I have no other choice but charge the phone every day.  

Please PleasePlease give us a proper update, not just sloppy poop!

That's the point. WiFi was not on all the time. Neither was the phone active for the 9 hours. Surely this explains the problem, is something not keeping it active that it previously has not done before. 36 hour between charges is usual for me, I have used Xperia for over 5 years now and never had a problem like this.
