What phone do you currently have?

I have a Samsung S4 and very much satisfied by its performance. In fact I have another normal Samsung model called “Guru” too. Even though the performance of Samsung S4 is quite good, it takes a back seat when it comes to power backup. Its battery does not hold power for long. So, I keep a basic Samsung model as a standby option. It has an amazing battery backup of 4-5 days even in low coverage areas. But, as I said, it is a basic model and not a smartphone. What I like most about Samsung S4 is its touch screen which is highly responsive and precise.
