Battery drain

[Mimgig]

Hello!

So since 1,5 week I have my Sony Xperia XZ. What I noticed from the beginning is the battery drain. I already had a few times that I go to sleep with 40% - 50% battery and in the morning my phone is like out and only gives warning low battery.
First I thought it was because of Stamina mode. I started using that since day one, cause I like to get best out of my battery. So I started to use other stamina mode but still same problem.

So yesterday I turned stamina mode off and still the battery is poor. Yesterday I went to sleep with 53% and woke up this morning with 14% left. I think that's not normal when you are not using your phone, am I right?!

I already turned off apps that I don't use, I use low screen brightness and always clean apps running on the background.
Update to Nougat also didn't approve battery life.

This morning I took a screenshot of what is using the battery most:

Android operatingsystem: 25%
Phone inactive : 14%
Android system: 12%
Screen: 9%
Google play : 9%
Mobile standby : 8%
WiFi : 5%
And some apps like WhatsApp, snapchat using less then 5%

So anyone has tips how to improve my battery, And are there more Xperia XZ users coping with the same problem?

Battery HEalth is good then i think you should try to Factory reset the device or Repair via Pc companion 

I don't think so it should've drained this much in Safe mode .... anyways keep monitoring

PCC is no longer supported @Mimgig

You have to use XC

I had same problem and sent phone back, fault was identified and have now over 2 weeks without a phone been finally sent a replacement phone which is draining battery almost as much, So I give up on Sony the battery life is worse than my 2 year old Z2 and I have to ask for refund unfortunately as I have always been a loyal Sony customer from TVs to MP3 players and phones this experience has really turned me off.
