Hi, guys.
I was thinking to switch to the latest S4 or Xperia Z so I went to do hands on both sets myself today. I tried the S4 at their concept store just now and it is very disappointing that the default UI lags like hell, just a simple scroll through the pages of home screen, it is very laggy and it come to a point that it hang there before it actually crashed.
I went to check the battery usage and to my surprised, it is using up to 92% of the battery with all the so-called smart features enabled.
So I tell myself that this is not the phone I will be wasting my money. I continue to test the demo set at the Telco and Xperia Z really very responsive in its homescreen UI, it is very smooth even there are so many background apps running and it never lag or hang at all.
I went to view the battery usage and the screen is only using less than 30% of the battery, the build quality is very solid compared to S4. The best part is that it is dust and water resistance and I will confirm to get the Xperia Z over the overrated S4.
