Hello. I have an XA, which I have the problem. If the navigation is running, screen is ON, the battery slowly drainig on charger also. I tried with different navigation apps, different charger, original Sony charger also. During 6-8 hours trip the battery goes down completely. My Z3C phone has the same apps, working well with the same chargers. This phone was in the sony service, the battery was changed, but still the same problem. Does anybody have the same problem, experience, any idea? Thank. Gábor
