Before I sleep, I checked my Xperia Z5 Premium Dual, it is 1 am and 75% battery left. But when I woke up at 9 am, it has only 57% left. This problem appears after I updated my phone to android 7.
i left with 95% agter 8 h sleep it was still 95%. did you make clean install or directly update?
Hi @Submar, sorry to hear about that.
Did you have the chance to take a look at what was draining the battery during this period of time? You may do so by going to Settings > Battery > Tap the battery icon, this will present you with a list of apps and services which have used battery. Try charging your device fully before going to bed and then leave it over night disconnected from the charger, than have a look in the list in the morning. It sounds like there may be some app or service in the background which could be running, so this is a good troubleshooting step in order to locate such an app.
Let me know what it looked like!

My phone doesn't have a severe battery drain today, only 3% deducted. Guess it was my mistake yesterday. Thank you, guys. However, I have close all apps and greenify them all for these 2 days, I wonder what causes the difference.

Only 4 cores working(A53) remaining 4 Cores (Cortex A57) Always stoped and still Baterry Dains. Sony has really dumped this Z Series Champ "XPERIA Z5". Phone Idle eating 25% always. Has tried fresh installations and No third party apps installed. Nougat for Z5 from Sony is too much carelessly baked. Hate Lost trust in Sony Mobile division for giving such bad software and also for acting so insensitive towards Z series flagships.

Nougat Update was insane.
The update process did not work correctly. after factory reset Nougat works well but the battery drains extremly fast (today 6 am 100% battery - 11 am 53% by typical use - right now (12.20 pm) 50% while loading!!!).
Usage 10% Android OS, 8% Clock, 8% Sleepmode (!), 8% Android System,7% Blackberry HUB, 6% Google Service,...others less than 5%.
What happened to my mobile?
