Usually my Xperia SP goes 2%down during night...but all of sudden,yesterday it went 40%down during the night. I really have no idea why this is happening... I included 3 pictures from the BetterBatteryStats app, it looks like that my phone wasnt even in the deep sleep because "Awake" stat is 15hours (that is probably the time since i unpluged the charger when it says 100% charged)
