This is a happy review about my mobile sony xperia t3.i bought it before 1.5 years.I usually keep up my mobile memory loaded utmost and dont normally close all apps, but still sony xperia t3 doesnt hang and will not create any problem to the process.Battery backup is one added up advantage.Once charged, the battery runs for a day even after frequent whatsapp usage.I am totally convinced with sony xperia t3.Thank u.
