Hi all 
I gave my Xperia X installed with SFOS 4.1 to my girlfriend some days ago.
She just complained to me about the heat and the quick battery drain.
I don’t remember having those issues while I was using this phone as a daily driver (from 2.x to 4.0).
Are these known issues of SFOS 4.1 on Xperia X ? What could we do to help find the root cause ?
Cheers, Samuel
