Hi all, Some months ago, I decided to use sMIUI 5.3.27 because everyone said it was the best ROM. I am still using it now. I think I followed the updates until July-August, so I know about miui 7 and I know about the repartitioning of memory and this morning I've learned about merged systems. The point is: in these days I've been experiencing loss of battery during night and I can't understand why. So I'm thinking to upgrade to last ROMs. My only question is: does the battery last like that on 5.3.27? It's the only feature I really need. Thank you.
