Drained over 30 % battery over night!

[Nifo]

Hello. 

I had about 85 % when going to bed (all apps closed), just alarm clock on. When I woke up this morning, the battery of my XZ2 Compact had drained around 30 % of the battery, and was down to about 50 %. Since this is a totally brand new phone (Pie Installed), Im not sure if this is normal - lets hope its not!

Any suggestions? Im using both Volte and Wifi-Calls. But that should not be any trouble, right? Im not using my phone during the nights. 

Im returning this phone for another brand, if this cant be fixed.

This is almost always an app issue. Is there a way you can provide a list of all the apps you have installed? I have noticed that using VPN or DNS kills the battery idling efficiency. What are the top apps that are draining? If it is Play Services/Android OS/System then this is likely a one off and you might want to give it a few more days for it to settle down.
