Much awaited Android 4.4.2 KitKat build was released for Xperia Z, ZL, ZR and Tablet Z by Sony recently in form of 10.5.A.0.230 firmware update but unfortunately along with many cool features of KitKat it brought a very problematic battery drain bug with it. Xperia Z KitKat users on 10.5.A.0.230 firmware are reporting a battery drain issue due to Google Play Services latest version which Sony support recently acknowledged on its forum also.
