Is the Phantom supposed to be warm when 'off'?

[jps75]

Hello,

I just bought a Phantom (and a Tree), and I've noticed that it remains noticeably warm even when not operating (i.e. in the morning after a whole night of being 'off'). This is especially evident in the heat sink area at the back, but the body is warm on top too. Not scolding hot, but definitely not cold and well above room temperature.
Is this normal behaviour?
Thanks.

Yes. It doesn't go off completely, just into standby mode. Mine is the same.
