After couple of days, battery is still a hit for sure unlike v46. But it seems a little better over v47. With heavy use and xlv profile running at 900 gave me little less than 6 hrs. With nominal use and xlv profile running at 900 gave me abt 10 hrs which is quite acceptable.

Now two things i notice, one it is taking longer for battery to charge and two there are sudden drops in battery power towards the end.
