xperia z1battery life worse after new android update

[KJC666]

Installed system update for android 4.4.2, and I am losing 75% of my charge after a full nights charging.
Normally ( before update) I would have 75% depleted when I put it on to charge
I am not constantly on my phone, not leaving apps open, my wireless, blutooth is off.
I have even installed battery defender, and it tells me it's being mostly used by "Google services"
I'm not even signed in to Google

Any suggestions please?

I have also experienced this and by the looks of these entries Sony aren't aware or are not interested?

Perhaps if enough of us make a point something might be done.

Over to you Sony as at the moment this device is not fit for purpose so I may be seeking compensation from you.

Fix it soon please!

Although I said this was the answer, Im not sure it was.

After the new update the problem no longer occurred
