Have you turn on the net and forgot to turn off?
If so the heat up may also be due to poor network coverage area as it has to use more energy to find and maintain signal also while net is ON some background app or auto update may also happen which may drain battery.Hope it helps you

That seems to be the case for me as well. All uncessary like BT, WiFi, Data etc is turned off and even Moderate Power Saving is turned off. I hope it gets fixed with future software updates. It's just that stand by optimisation is not great on this device.

EDIT: I mistakenly said "Moderate Power Saving is turned off". What I forgot to mention was that turning it ON before you go to sleep can tremendously reduce battery consumption. I have setup a "Save battery at night" Routine which auto sets the MPS till morning, since there is no need for the phone to be working at its potential then.

I think you are right that the standby optimization is not that gr8 on this device
