Xperia XA - Horrendous battery life

[andvivia7]

I am getting barely 2.5 hours on screen time with the Xperia XA. I'm not doing anything stupid like leaving it on max brightness (it's auto) and I don't run masses of apps - in fact as you can see from the screen grabs it is clearly the display which is the main culprit. 

How on earth is this supposed to reach the advertised 2 days battery life? By not using it? It's absolutely useless.... very unhappy, particularly because it is otherwise a rather nice little device with that edge-to-edge screen.

Have I got a dodgy battery?!

Guys, the only thing that helped me was to turn off Smart cleaner.

Hi everyone! 

I have problems with battery drainage overnight when I lose around 40% of my battery. Sony stated that there was a software error previously and they will come up with an update that will fix this, but I have done all the updates (currently 33.2.A.3.81) and I still have this problem. My locaton scanning is off, I have also done a factory reset and everything and I still experience this problem. 

Does anyone face the same problem and know how to solve it?
