The Battery Drain SUPER Fast!

[AndrewYs]

Hello Guys! I just bought my Xperia Z2 Two Days Ago and I found an issue about that my battery drain really really **bleep** fast and it also felt hot! In Normal State my phone can just only last for 8hours or less with my many things turned off,even if I turned on Stamina Mode it doesn't make any better too,it can only last for 1day or less!
Can anyone help me or tell me what to do?

Mine has the same issue after the update, I've downloaded an app "Gsambattery" and checked, found out it's caused by "Google service", used the app to disabled the service and problem solved.
