In itself it was a good smartphone, safely at least. 4 star value. Unfortunately, Sony does not manage to deliver clean Updates. After 4.4.2 Kitkat the battery in 12 hours Standby is empty. Since you have not yet used your phone. Thus you have a mobile experience at the outlet. The recommendations that Google Play to downgrade services or disable several functions I know the way. This works reasonably well. From a premium manufacturer, however, I expect a bit more than the advice not to use the functions of my cell phone, so the battery lasts throughout the day. And for weeks since the update. Error is known and is not resolved. My next is certainly not a Sony more.
